and behavior to acclimatize seasonal enforcement easily without altering body homeostasis.
The prime principle of Ayurvedic system of medicine is preventive aspect, can be achieved
by the change in diet and practices in response to change in climatic condition. This is a very
important aspect of preventive medicine as mentioned in Ayurvedic texts. Lifestyle disorders
are very common in the present era, basically originating from lack of following seasonal
regimens due to lack of concentration in seasonal characteristics. A rm scientic analysis is

Introduction
Ayurveda, the age old science of life, has always emphasized to
maintain the health and prevent the diseases by following proper
diet and lifestyle regimen rather than treatment and cure of the
diseases. The basic principle followed in the Ayurvedic system
of medicine is Swasthyashya Swasthya Rakshanam, which means
to maintain the health of the healthy, rather than Aturashya
Vikara Prashamanancha, means to cure the diseases of the
diseased.[1] For this purpose the Dinacharya (daily regimen)
and Ritucharya (seasonal regimen) have been mentioned in the
classics of Ayurveda.[2]
With the change in season, the change is very evident in the
environment we live in. We see various changes in bio-life
around us, such as flowering in spring and leaf-shedding in
autumn in the plants, hibernation of many animals with the
coming of winter, and so on. As human being is also part of
the same ecology, the body is greatly influenced by external
environment. Many of the exogenous and endogenous rhythm
have specific phase relationship with each other; which means
that they interact and synchronize each other. If body is unable
to adopt itself to stressors due to changes in specific traits of
seasons, it may lead to Dosha Vaishamya, which in turn may
render the body highly susceptible to one or other kinds of
disorders.[3]
As adaptations according to the changes, is the key for
survival , the knowledge of Ritucharya (regimen for various
seasons) is thus important. People do not know or ignore the
suitable types of food stuffs, dressing, and others regimen to
be followed in particular season, this leads to derangement
of homeostasis and causes various diseases, such as obesity,
diabetes, hypertension, cancer, and so on. Lifestyle diseases are
a result of an inappropriate relationship of people with their
environment. Onset of these lifestyle diseases is insidious,
delayed development, and difficult to cure.[4] In our country
the situation is quite alarming due to rapid changing of disease
profile. The World Health Organization has identified India as
one of the nations that is going to have most of the lifestyle
disorders in the near future. Nowadays, not only are lifestyle
disorders becoming more common, but they are also affecting
younger population. Hence, the population at risk shifts
from 40+ to maybe 30+ or even younger. Already considered
the diabetes capital of the world, India now appears headed
toward gaining another dubious distinction of becoming the
lifestyle-related disease capital as well. A study conducted
jointly by the All India Institute of Medical Sciences and Max
Hospital shows the incidence of hypertension, obesity, and heart
disease is increasing at an alarming rate, especially in the young,
urban population. According to the doctors, a sedentary lifestyle
combined with an increase in the consumption of fatty food
and alcohol is to blame cases of obesity, diabetes, hypertension,
and so on.
Ritucharya is prominently discussed in the first few chapters

AYU | Oct-Dec 2011 | Vol 32 | Issue 4 467
Thakkar, et al.: Ritucharya for lifestyle disorders
of most of the Samhitas of Ayurveda. Prevention of disease to
maintain health is being the first and foremost aim of the holistic
science of Ayurveda. In Tasyashitya chapter of Charaka Samhita,
it is said “Tasya Shitadiya Ahaarbalam Varnascha Vardhate.
Tasyartusatmayam Vaditam Chestaharvyapasrayam,” which means
‘the strength and complexion of the person knowing the suitable
diet and regimen for every season and practicing accordingly
are enhanced.[5] Main theme of this chapter is to make people
aware concerning the methods to live in accordance with the
environment. In this article, the Ritucharyas mentioned in the
classics of Ayurveda have been discussed and emphasis has been
given on the likely impact of Ritucharya on lifestyle disorders.
Classification of season
The year according to Ayurveda is divided into two periods
Ayana (solstice) depending on the direction of movement of
sun that is Uttarayana (northern solstice) and Dakshinayana
(southern solstice). Each is formed of three Ritus (seasons).
The word Ritu means “to go.” It is the form in which the
nature expresses itself in a sequence in particular and specific in
present forms in short, the seasons.[6]
A year consists of six seasons, namely, Shishira (winter), Vasanta
(spring), and Grishma (summer) in Uttarayan and Varsha
(monsoon), Sharata (autumn), and Hemanta (late autumn) in
Dakshinayana. As Ayurveda has its origin in India, the above seasonal
changes are observed predominantly in Indian subcontinent.
Uttarayana and its effect
Uttarayana indicates the ascent of the sun or northward
movement of the sun. In this period the sun and the wind are
powerful. The sun takes away the strength of the people and
the cooling quality of the earth. It brings increase in the Tikta
(bitter), Kashaya (astringent), and Katu (pungent) Rasa (taste),
respectively, which brings about dryness in the body and reduces
the Bala (strength). It is also called Adana Kala.
According to modern science, this can be compared with the
gradual movement of earth around the sun to the position,
in which the rays of the sun falls perpendicularly at 30 degree
meridian of the North Pole on June 21st every year, called as
summer solstice. The northward journey of the Sun from Tropic
of Capricorn to Tropic of Cancer happens.
During Uttarayana the seasonal changes in Indian subcontinent
is from Shishira (winter) to Vasanta (spring) and to Grishma
(summer). The period can be compared to mid-January to
mid-July, when warmness and dryness in weather increases.
It has an overall debilitating effect on environment, to which
human being is also a part.
Dakshinayana and its effect
Dakshinayana indicates the descent of the sun or movement of
the sun in southern direction. In this period, the wind is not very
dry; the moon is more powerful than sun. The earth becomes
cool due to the clouds, rain, and cold winds. Unctuousness
sets in the atmosphere and Amla (sour), Lavana (salty), and
Madhura (sweet) Rasa are predominant, so the strength of
person enhances during this period. It is also called Visarga Kala.
According to modern science, this can be compared with the
gradual movement of the earth around the sun to the position,
in which the rays of the sun fall over 30 degree meridian of
the South Pole perpendicularly on December 21st every year, is
called as winter solstice. The southward movement of the Sun
occurs from Tropic of Cancer to Tropic of Capricorn.
During Dakshinayana, the seasonal changes occur in the Indian
subcontinent from Varsha (monsoon) to Sarata (autumn) and to
Hemanta (late autumn). This period can be compared to mid-July
to mid-January, when cool sets, and due to which anabolic activity
dominates over the catabolic activity in the environment.
State of strength
In the beginning of Visarga Kala and ending of Adana kala, that
is, during Varsha and Grishma, weakness occurs. In the middle
of the solstices, that is, during Sharata and Vasanta, strength
remains in moderate grade and in the end of Visarga Kala and
in the beginning of Adana Kala, that is, during Hemanta and
Shishira, maximum strength is seen.[7]
Regimen of different seasons

Discussion
This is the way the ancient sages set up the regimen for various
seasons on analytical reasoning to obtain Swastha (health) and
prevent the diseases. The examples set by them stand as a hint to
decide other dos’ and don’ts’ in the regimen—Ritucharya [Table 1].
The environmental factors include the nature of the land, water,
and various atmospheric phenomena, including temperature,
humidity, wind, rain, clouds, and atmospheric pressure. All
these environmental factors undergo a continuous change and
at a time, no two moments are exactly alike in a given place.
Thus with the rising Sun the temperature keeps on rising
and gradually drops at night. The maximum and minimum
temperature fluctuates daily but it is highest in summer and
lowest in winter. Similarly, all these factors show diurnal as well
as seasonal variations and these variations for a particular time
are known as season.[14]
A study on animals with seasonal changes revealed the effects of
photoperiod on immune function and hormone synthesis which
influence the development of opportunistic disease.[15] Another
study indicated that free-living species from many regions can
seasonally modulate glucocorticoid release. In other words,
the magnitudes of both unstressed and stressed glucocorticoid
concentrations change depending on the time of the year.[16]
A human clinical study was carried out by Mallika et al. to
assess the biophysical and biochemical changes occurring due to
Ritusandhi. Clinical study shows provocation of Tridosha with the

dominance of Vata and Kapha provocation. In this study during
Ritusandhi frequently, Jwara, Pratishyaya, and Alasya Lakshnas were
met with. In Agnibala also although remarkable changes are seen,
they are not up to pathologic mark. Regarding the biochemical
changes, there is a varied pattern—sometimes increasing and
decreasing, but all these are within the range of normal variations.
The variation in biochemical values are seen but not remarkable.[3]
One study carried out by Jangid et al. on the concept of Ritus
and their effect on Bala reported that the overall effect of
Hemanta Ritu on Bala of healthy volunteers was maximum,
effect of Vasanta Ritu was moderate and the effect of Varsha
Ritu was minimum, and concluded that Hemanta is the Ritu
of Pravara Bala, Vasanta is the Ritu of Madhyama Bala and
Varsha is the Ritu of Avara Bala. Results of the study support
the principles of Ayurveda.[14]
Many other systems of medical science have observed the
influence of seasonal rhythm in physical and mental health. To
quote Hippocrates, “Whoever wishes to investigate medicine
properly should proceed thus in the first place to consider the
seasons of the year and what affect each of them produces.”[17]
Even in Tibetan system of medicine, seasons are regarded as
one of the fundamental factors in etiology and pathology, and a
powerful instrument in the prevention of diseases.
In Ayurveda, the knowledge of Ritucharya is a first hand guide
to the concept of Kriya-Kala, which describes the modes and
stages of the development of diseases, with regard to the state
of different DoshasVatu, Pitta, and Kapha in accordance
with the changes of time. A good understanding of it is very
much essential for early diagnosis and prognosis for adopting
preventive and curative measures.
It is to be known that disharmony in the DoshasVatu, Pitta,
and Kapha results in Roga (disease). And aim of the science
of Ayurveda is to maintain the harmony. With changes in
diet and lifestyle, there are changes in the state of Tridosha,
which is bound to affect us, resulting disharmony, causing
lifestyle diseases. Ritu acts as Vyanjaka or Nimittakarana in
the aggravation and manifestation of disease. For example,
an evening (afternoon) headache is essentially with Vata
predominance. Diseases due to Vata show a tendency to
aggravate during the rainy season.[18]
It has been observed that there is an increased occurrence of
flu, dry skin in winter, heat stroke in summer, pollen allergy in
spring, high incidence of air and water borne diseases in rainy
season, and skin diseases in autumn. Thus it can be said that
physiology vindicates the concept of Ritucharya.[19] Studies
have even revealed the increased incidence of Asthma attack
in winter season. There is also a reference of Seasonal Affective
Disorder in modern science.[20]
Peoples’ diet changed substantially in the second half of
20th century, generally with increased consumption of meat, dairy
products, vegetable oils, fruit juice, and alcoholic beverages, and
decreased consumption of starchy staple foods, such as bread,
potatoes, rice, and maize flour. These observations suggest that
the diets [or lifestyle] of different populations might partly
determine the rates of cancer, and other lifestyle disorders, such
as obesity, diabetes, cardiovascular diseases, etc.[21] In 1900, the
top three causes of death in the United States were pneumonia/
influenza, tuberculosis, and diarrhea/enteritis. Communicable
diseases accounted for about 60% of all deaths. In 1900, heart
disease and cancer were ranked number 4 and 8, respectively.
Since the 1940s, the majority of deaths in the United States
have resulted from heart disease, cancer, and other degenerative
diseases. And, by the late 1990s, degenerative diseases
accounted for more than 60% of all deaths.[22]
Already considered the diabetes capital of the world, India now
appears headed towards gaining another dubious distinction of
becoming the lifestyle-related disease capital as well. A study
conducted jointly by the All India Institute of Medical Sciences
and Max Hospital shows that the incidence of hypertension,
obesity, and heart disease is increasing at an alarming rate,
especially in the young, urban population.[23]
Doctors however say a strict diet and regular exercise along
with cholesterol controlling drugs can go a long way in checking
lifestyle diseases. But with the knowledge of Ritucharya we can
surely avoid these by practicing regimen in accordance with
the Ritu to maintain the harmony of the Tridosha and to stay
healthy ever. Growing public awareness, with the support of the
government and corporate wellness programs may help arrest
the rapid increase in the incidence of such diseases, saving lives
and crores of rupees in costs.
With global warming and variation in the advent of season, it can
surely be a query, of the importance of Ritucharya in the present
scenario. It is to be understood that the background on which
Ritucharya is based, that is, Dosha and Panchamahabhuta theory.
Although today Ritus do not follow uniformity, the level of Dosha
and Panchamahabhuta can be analyzed accordingly, to decide the
regimen, to which this knowledge of Ayurveda holds as a pathfinder.
These principles surely demand a closer observation for clarity.

Background: The prevalence of type 2 diabetes (T2D) has increased substantially in the past few decades throughout the world. In India, the epidemic of diabetes continues to increase irrespective of area, status, and age. Despite various scientific societies involved in the treatment of diabetes, still, the burden of diabetes keeps growing. Aims: The aim of this work is to explore the Ayurvedic concept of a personalized diet to modulate the gut microbiota for the treatment of T2D. Material and methods: A thorough study of literature from online scientific databases including Web of Science, PubMed, Scopus, and Google Scholar as well as from classical texts of Ayurveda was done. A careful compilation was done to extract the valuable output of the personalized diet to modulate the gut microbiota. Results: There are various diets used to control blood glucose levels, and their effects are also being studied on the transcriptome or epigenome despite 99.9% genomic similarity among human beings. However, microbiomes have only 10% similarity. Ayurvedic diet is given on the basis of Prakriti (body constitution), therefore, it is also called personalized diet. Conclusion: The diets prescribed for T2D in Ayurveda are high in fibers, polyphenols, and complex carbohydrates which enrich butyrate‑producing bacteria and decrease lipopolysaccharide‑producing bacteria. Hence, there is a need to have a personalized diet to manage the glucose level by enriching beneficial gut microbiota. The approach of a personalized diet associated with gut microbiota can be helpful in maintaining blood sugar in T2D patients. Keywords: Ayurvedic diet, gut microbiota, personalized diet, Prakriti, type 2 diabetes

Indian menstruators have followed various menstrual rituals or beliefs for an eternity now. These rules and restrictions constructed in ancient India were based on numerous observations and logics and were handed down to women through centuries of chain of wisdom by their mothers and grandmothers. Today’s modern women though don’t shy away from calling every restriction a myth and every cultural practise a sham. To resolve this confusion, this article explores the various menstrual beliefs and practices from India along with the logical explanations from an array of literature as to why these practices were started in the first place.

The effect of harmful diet as well as activities of the mother causes congenital anomalies. The psychology of pregnant woman may also affect the foetus growth in her womb. Vedas considered the fact that for achievement of conception, happiness and good psychology of woman is an important factor [1]. The period of pregnancy and the intrauterine environment are crucial to the tendency to develop diseases like Cancer, hypertension, diabetes etc. Similarly, the maternal lifestyle, particularly diet, exercise and smoking during pregnancy, have an important role in determining the risk to develop diseases that manifest themselves both during childhood and particularly in adulthood [2]. Maternal behaviour during early periods of life can alter the epigenetic state of the foetal DNA. Maternal stress and maternal-placental-foetal biological mediators of stress can affect foetal development. In fact, it has been showed that exposure to maternal psychosocial stress during intrauterine life is associated with significantly shorter leukocyte telomere length in young adulthood, a predictor of disease onset and mortality. The present literary / conceptual study thus focuses mainly on interpreting these reviews, on the basis of modern scientifc knowledge and intervention of personalised Dincharya & Ritucharya to prevent prevalence of cancer.
... Ritu contributes various changes in nature (Baghel et al., 2018). The Ritu concept is based on the changes in vegetation phenology like flowering, fruiting and leaf shedding (Thakkar et al., 2011), as well as on the temperature, climate, movement of sun in celestial sphere and the day length. Whole year is divided in six Ritus (seasons) (Krishnan, 2020) and each Ritu is approximately consist of two months (Singh et al., 2012a) Table.1. ...

Amphibian and reptiles are weather sensitive, poikilothermic group of animals, and their occurrence varies with the change in seasons. Present study was conducted in Ramnagar Forest Division of Uttarakhand state of India. Ramnagar Forest Division is the western part of Terai Arc Landscape which is an important ecoregion of the world. Sampling was done with Visual Encounter Surveys along with other methods, in all the seasons of a year. A total of 47 species of herpetofauna was recorded in the study, including 10 species of frogs, 13 species of lizards, 20 species of snakes and 4 species of testudines. The maximum number of herpetofauna species was observed during monsoon season, while the least number species were found in winters. The general pattern of herpetofauna species richness that observed in Ramnagar Forest Division was, found to be highest in monsoons, which then started decreasing in autumns and a rapid decrease was noticed in pre-winter and reached minimum in winters. In springs it started rising again and continue to rise in summers to reached maximum in monsoons
... Ayurveda is a perennial source of knowledge, known to mankind since several thousands of years, about cause, features and treatment of diseases, and ways to restore as well as promote health. Our ancient Acharyas explain Ritucharya which means methods for adapting with the changing environment (3) which is not in our control. Ritu or season appear in nature due to the movement of sun, the prime energy source of the nature. ...

Ayurveda is an ancient system of medicine, clearly mentioned epidemic under a broad term 'Janapadodhwansa'. According to Ayurveda there are two types of Vyadhis based on causative factors which are stated in Charaka Samhita vimansthan chapter 3. Acharya Sushruta called it as Maraka and Acharya Bhela called it as Janamaar. There are four factors that has been described which are getting vitiated in Janopadodhwamsa.These are Vayu (air),Jala (water),Desha (land) and Kaala (season). Among these four factors Kaala is mainly main factor. Many of today's medical sciences coincide with some of the basic principles of Ayurveda.Today whole world is suffering from the COVID-19 pandemic.To assess the concepts of epidemiology in Ayurveda and to compare the same with recent COVID-19 pandemic, literary study of the epidemic was done thoroughly, including classical treatises like Charaka Samhita, Sushruta Samhita & modern textbooks of epidemiology. Most of the concepts of Ayurveda about Janopadodhwamsa are found relevant to current theories of pandemic/epidemic. When COVID-19 pandemic compares with Janopadodhwamsa, it shows similarity in concepts like causative factors,modes of transmission,methods of prevention of outbreaks etc.Also,control measures of COVID-19 can be compared with Hetu-viparit & Vyadhi-viparitchikitsa. The concepts described in Ayurveda regarding Janapadodhwansa are more or like the present modern concept of the pandemic or epidemic.Thus, the ancient Indian medicinal systems were well known to the fact of the epidemics & outbreaks of infectious diseases

Reproductive health is a universal concern, a central determinant of quality of life. Male reproductive health disorders can evolve at any phase of life, but accountability of males in maintenance of reproductive and sexual health is seemingly low. Preconception care for men discloses a reproductive health plan, health assessment, health promotion, clinical and psychosocial interventions to improve the adolescent and men in reproductive age groups. In Ayurveda the necessity of sound reproductive health for successful conception is explained under dinacharya (daily regimen), ritucharya (seasonal regimen), sadvritta (code of conduct for keeping good and balanced condition of body and mind), panchakarma (purificatory therapies), rasayana (rejuvenation therapy) and vajikarana (aphrodisiac therapy). Research studies paved less limelight to address the need for preserving the same right from an early phase of life. It is the privilege to avail the possibilities from both ayurvedic and contemporary science to upgrade reproductive health, which in turn enhances positive eugenics. This review is intended with an attempt to detail the ayurvedic aspects of male reproductive health with special reference to preconception care.

A dinacharya, or daily routine, is one of the best practices that one can do to prevent and manage cardiovascular disease (swastha Raksha-maintenance of health and rogir chikitsa-treatment of patient). Din means “day” and charya means “routine,” making a literal translation from Sanskrit of “daily routine.” It means merging the daily cycle with the natural cycle of the solar system. The yogic rishi (a person who practices self-realization as a yogi or yogini) considers daily routine to be a stronger healing force than any other curative medicine. Dinacharya activates relaxation response and parasympathetic tone to counteract the sympathetic overdrive of stress the cause of cardiovascular disease.

World is suffering a huge crisis because of COVID 19 pandemic. Apart from this burden of noncommunicable diseases (NCD’s) is also too high. We get very good comprehensive measures in Ayurveda, which will protect our body from both Infective diseases & NCD’s. It is recently; Modern science has come to know about disturbance in circadian rhythms (biological clock) by means of faulty diet, untimely eating & performing tasks at wrong time’s causes many diseases. Ayurveda already knew that environmental changes in whole day have effects on our body and to synchronize with them they mentioned Dincharya. Apart from this they were also aware of ef- fects of seasonal changes on human body and to synchronize with them they have mentioned Rutucharya. Based on seasonal changes Aacharyas have classified six Rutu’s namely Shishira, Vasanta, Grishma, Varsha, Sharad and Hemant. According to their effects on body different Rutucharyas are told. At present Indian calendar seems to be slightly out of phase with seasons but with help of tropical phenomena like solstices, equinoxes with respect Uttarayan, Dakshinayan & seasonal markers mentioned in Samhitas we can mark exact seasons. Based on Ayur- vedic Siddhantas we can understand different Rutucharyas & can implicate them in our present routine. Keywords: Rutucharya, Seasonal Regimen, Lifestyle, Diet, Dakshinayan, Uttarayan.

A randomized Survey study was done on healthy volunteers to evaluate effect of Ritu on Bala, as mentioned in Charaka-Sutrasthâna-6/8. According to which, the beginning of the Visarga kâla i.e Varshâ and the end of the Âdâna Kâla i.e. Grîshma Ritu mark the Daurbalya (Decreased Bala) of the Human being. While the end of Visarga Kâla i.e. Hemanta and the beginning of Âdâna Kâla i.e. Shishira Ritu signify maximum Bala and middle of the both Kâlas i.e. Sharad & Vasanta Ritu respectively medium Bala is observed. To prove the validity of the principle Sûtra, 95 healthy volunteers were registered, out of which 80 continued through out the study period for the Bala assessment. The Bala assessment was performed with the help of a specific scoring pattern based upon 12 parameters (from Âyurveda as well as Modern science), in three different Ritus viz. -Hemanta, Vasanta and Varshâ. The study illustrated significant to highly significant differences in the most of the parameters, which is supportive to the selected Sûtra that the maximum Bala is found in Hemanta Ritu, medium Bala in Vasanta while minimum in Varshâ Ritu.

The purpose of this study was to determine the impact of chronic diseases of lifestyle on the mortality pattern of South Africans and to estimate the number of South Africans affected by major risk factors for these diseases. The proportion of deaths due to chronic diseases of lifestyle was calculated from the deaths reported to the Central Statistical Services. This group of diseases was responsible for 24.5% of deaths of all South Africans and 28.5% of those aged 35-64 years whose deaths were reported in 1988. The major causes of death contributing to these figures were cerebrovascular diseases (7.2% of all deaths and 7.9% of deaths of persons aged 35-64 years) and ischaemic heart disease (8.7% of all deaths and 9.6% of deaths of persons aged 35-64 years). The age-standardised prevalence rates for the major risk factors reported in five cross-sectional studies in different areas and groups are compared. Estimates from the reported prevalence rates, based on the size of the South African population recorded in the 1985 census figures, were calculated for the major risk factors. Overall 4.88 million South Africans smoked, the largest group of smokers being black males (2.6 million). for hypertension 5.5 million South Africans had blood pressures above 140/90 mmHg; again the largest groups were blacks (3.0 million). For hypercholesterolaemia and raised low-density lipoprotein cholesterol levels, 4.8 million and 3.1 million South Africans respectively had an increased risk for ischaemic heart disease, blacks having the lowest levels.(ABSTRACT TRUNCATED AT 250 WORDS)

Winter is energetically demanding. Physiological and behavioral adaptations have evolved among nontropical animals to cope with winter because thermoregulatory demands increase when food availability decreases. Seasonal breeding is central within the suite of winter adaptations among small animals. Presumably, reproductive inhibition during winter conserves energy at a time when the adds of producing viable young are low. In addition to the well-studied seasonal cycles of mating and birth, there are also significant seasonal cycles of illness and death among many populations of mammals and birds in the field. Challenging winter conditions. such as low ambient temperatures and decreased food availability, can directly induce death via hypothermia, starvation or shock. In some cases, survival in demanding winter conditions puts individuals under great physiological stress, defined here as an adaptive process that results in elevated blood levels of glucocorticoids. The stress of coping with energetically demanding conditions can also indirectly cause illness and death by compromising immune function. Presumably, the increased blood concentrations of adrenocortical steroids in response to winter stressors compromise immune function and accelerate catabolic mechanisms in the field, although the physiological effects of elevated glucocorticoids induced by artificial stressors have been investigated primarily in the laboratory. However, recurrent environmental stressors could reduce survival if they evoke persistent glucocorticoid secretion. The working hypothesis of this article is that mechanisms have evolved in some animals to combat seasonal stress-induced immunocompromise as a temporal adaptation to promote survival. Furthermore, we hypothesize that mechanisms have evolved that allow individuals to anticipate periods of immunologically challenging conditions, and to cope with these seasonal health-threatening conditions. The primary environmental cue that permits physiological anticipation of season is the daily photoperiod; however, other environmental factors may interact with photoperiod to affect immune function and disease processes. The evidence for seasonal fluctuations in lymphatic organ size, structure, immune function, and disease processes, and their possible interactions with recurrent environmental stressors, is reviewed. Seasonal peaks of lymphatic organ size and structure generally occur in late autumn or early winter and seasonal minima are observed prior to the onset of breeding. Although many of the field data suggest that immune function and disease processes are also enhanced during the winter, the opposite seasonal pattern is also observed in some studies. We propose that compromised immune function may be observed in some populations during particularly harsh winters when stressors override the enhancement of immune function evoked by short day lengths. Because so many factors covary in field studies, assessment of our proposal that photoperiod mediates seasonal changes in immune function requires laboratory studies in which only photoperiod is varied. A review of the effects of photoperiod on immune function in laboratory studies reveals that exposure to short day lengths enhances immune function in every species examined. Short day exposure in small mammals causes reproductive inhibition and concomitant reduction in plasma levels of prolactin and steroid hormones, as well as alterations in the temporal pattern of pineal melatonin secretion. These hormones affect immune function, and influence the development of opportunistic diseases, including cancer: however, it appears that either prolactin or melatonin secretion is responsible for mediating the effects of photoperiod on immune function. Taken together, day length appears to affect immune function in many species, including animals that typically do not exhibit reproductive responsiveness to day length.

Until now, prospective studies of aging have begun with 50-60-year-olds, not adolescents. Premature death, childhood variables, and alcohol abuse have been often ignored, as has successful aging. The authors reviewed the existing literature on health in late life in order to highlight that, increasingly, successful aging is not an oxymoron. The present study followed two cohorts of adolescent boys (237 college students and 332 core-city youth) for 60 years or until death. Complete physical examinations were obtained every 5 years and psychosocial data every 2 years. Predictor variables assessed before age 50 included six variables reflecting uncontrollable factors: parental social class, family cohesion, major depression, ancestral longevity, childhood temperament, and physical health at age 50 and seven variables reflecting (at least some) personal control: alcohol abuse, smoking, marital stability, exercise, body mass index, coping mechanisms, and education. The six outcome variables chosen to assess successful aging at age 70-80 included four objectively assessed variables (physical health, death and disability before age 80, social supports, and mental health) and two self-rated variables (instrumental activities of daily living and life enjoyment). Multivariate analysis suggested that "good" and "bad" aging from age 70-80 could be predicted by variables assessed before age 50. More hopeful still, if the seven variables under some personal control were controlled, depression was the only uncontrollable predictor variable that affected the quality of subjective and objective aging. One may have greater personal control over one's biopsychosocial health after retirement than previously recognized.

Relative risk estimates suggest that effective implementation of behaviors commonly advocated in preventive medicine should increase life expectancy, although there is little direct evidence. To test the hypothesis that choices regarding diet, exercise, and smoking influence life expectancy. A total of 34 192 California Seventh-Day Adventists (75% of those eligible) were enrolled in a cohort and followed up from 1976 to 1988. A mailed questionnaire provided dietary and other exposure information at study baseline. Mortality for all subjects was ascertained by matching to state death tapes and the National Death Index. California Adventists have higher life expectancies at the age of 30 years than other white Californians by 7.28 years (95% confidence interval, 6.59-7.97 years) in men and by 4.42 years (95% confidence interval, 3.96-4.88 years) in women, giving them perhaps the highest life expectancy of any formally described population. Commonly observed combinations of diet, exercise, body mass index, past smoking habits, and hormone replacement therapy (in women) can account for differences of up to 10 years of life expectancy among Adventists. A comparison of life expectancy when these factors take high-risk compared with low-risk values shows independent effects that vary between 1.06 and 2.74 years for different variables. The effect of each variable is assessed with all others at either medium- or high-risk levels. Choices regarding diet, exercise, cigarette smoking, body weight, and hormone replacement therapy, in combination, appear to change life expectancy by many years. The longevity experience of Adventists probably demonstrates the beneficial effects of more optimal behaviors.

Diet-related factors are thought to account for about 30% of cancers in developed countries. Obesity increases the risk of cancers in the oesophagus, colorectum, breast, endometrium, and kidney. Alcohol causes cancers of the oral cavity, pharynx, larynx, oesophagus, and liver, and causes a small increase in the risk of breast cancer. Adequate intakes of fruit and vegetables probably lower the risk for several types of cancer, especially cancers of the gastrointestinal tract. The importance of other factors, including meat, fibre, and vitamins, is not yet clear. Prudent advice is to eat a varied diet including plenty of fruit, vegetables, and cereals to maintain a healthy bodyweight with the help of regular physical activity and to restrict consumption of alcohol.

The vertebrate stress response helps animals respond to environmental dangers such as predators or storms. An important component of the stress response is glucocorticoid (GC) release, resulting from activation of the hypothalamic-pituitary-adrenal axis. After release, GCs induce a variety of behavioral and physiological changes that presumably help the animal respond appropriately to the situation. Consequently, GC secretion is often considered an obligatory response to stressful situations. Evidence now indicates, however, that free-living species from many taxa can seasonally modulate GC release. In other words, the magnitudes of both unstressed and stressed GC concentrations change depending upon the time of year. This review examines the growing evidence that GC concentrations in free-living reptiles, amphibians, and birds, but not mammals, are commonly elevated during the breeding season. This evidence is then used to test three hypotheses with different focuses on GC's energetic or behavioral effects, as well as on GC's role in preparing the animal for subsequent stressors. These hypotheses attempt to place annual GC rhythms into a physiological or behavioral context. Integrating seasonal differences in GC concentrations with either different physiological states or different life history stages provides clues to a new understanding of how GCs actually help in survival during stress. Consequently, understanding seasonal modulation of GC release has far-reaching importance for both the physiology of the stress response and the short-term survival of individual animals.
