Unlike younger women, the risk of cardiovascular disease in older women matches or exceeds that of men. Excessive cortisol may play a role in this increased risk. Here we explore the possibility that the Transcendental Meditation (TM) program may reduce the cortisol response to a metabolic stressor as a way of reducing disease risk in older women. Data from 16 women who were long-term practitioners of transcendental meditation (mean = 23 y) were compared with data from 14 control women matched for age (mean = 75 y, range = 65-92 y). Data on demographics, disease symptoms, and psychological variables were collected, and cortisol response to a metabolic stressor (75 g of glucose, orally) was examined in saliva and urine. Pre-glucose levels of salivary cortisol were identical for the two groups. Post-glucose cortisol rose faster in the controls and was significantly higher than that in the TM women (P < 1 3 10(-4)). Urinary excretion of cortisol during this period was 3 times higher in controls than in the TM women (2.4 +/- 0.17 and 0.83 +/- 0.10 microg/h, respectively; P = 2 x 10(-4)). In addition, the number of months practicing transcendental meditation was inversely correlated with CVD risk factors. Lower cortisol response to metabolic challenge may reflect improved endocrine regulation relevant to the disease-preventing effects of transcendental meditation in older women.

    • "One that examined nondepressed HIV+ patients reported that a stress management intervention designed to increase spiritual growth led to an increase in lymphocyte proliferation and a 3-fold increase of INF-γ [104]. Likewise, Eastern spiritual meditation has been shown to increase antibody response to influenza vaccine [105], alter the ratio of pro-/anti-inflammatory cytokines [106, 107], increase NK cell activity [107], reduce cortisol [107–110], and decrease catecholamine [111, 112] levels (and in one study, there was a trend toward superiority over conventional CBT [113]).

    ABSTRACT: This paper (1) reviews the physical and religious barriers to CBT that disabled medically ill-depressed patients face, (2) discusses research on the relationship between religion and depression-induced physiological changes, (3) describes an ongoing randomized clinical trial of religious versus secular CBT in chronically ill patients with mild-to-moderate major depression designed to (a) overcome physical and religious barriers to CBT and (b) compare the efficacy of religious versus secular CBT in relieving depression and improving immune and endocrine functions, and (4) presents preliminary results that illustrate the technical difficulties that have been encountered in implementing this trial. CBT is being delivered remotely via instant messaging, telephone, or Skype, and Christian, Jewish, Muslim, Buddhist, and Hindu versions of religious CBT are being developed. The preliminary results described here are particular to the technologies employed in this study and are not results from the CBT clinical trial whose findings will be published in the future after the study ends and data are analyzed. The ultimate goal is to determine if a psychotherapy delivered remotely that integrates patients' religious resources improves depression more quickly than a therapy that ignores them, and whether religious CBT is more effective than conventional CBT in reversing depression-induced physiological changes.

    • "When the cortisol levels were analyzed in a study on Transcendental Meditation, the cortisol levels in 8 meditators and nonmeditators were compared before, during, and after a meditation session and there was a significant drop in the meditation group [27]. Walton et al. [28] and Mc Lean et al. [29, 30] have done several studies on the effect of TM on cortisol levels, and they found that the technique lowered cortisol in normal subjects and also postmenopausal women exposed to laboratory stressors. Serum cortisol levels were found to be significantly reduced in 52 males after the practice of Buddhist Dhammakaya Meditation in comparison with 30 nonmeditators [22]. "

    ABSTRACT: THE OBJECTIVE WAS TO FIND OUT THE EFFECT OF INTEGRATED AMRITA MEDITATION TECHNIQUE (IAM) ON THE STRESS HORMONES: adrenaline and cortisol. One hundred and fifty healthy subjects were randomized into three groups. Blood was collected at 0 hour, 48 hours, 2 months, and 8 months after the first visit. Adrenaline was analyzed by ELISA and cortisol by Chemiluminescent method. In the IAM, PMR and control groups 44, 44, and 36 came, respectively, for the baseline visit. Within group, cortisol and adrenaline levels reduced in the IAM 48 hours onwards and the fall sustained until 8 months (P < .05). ANCOVA (Repeated measures) on adrenaline taking the four levels of observation showed a highly significant (P = .001) drop in the IAM group. The mean cortisol values between groups were not statistically significant (P = .138). IAM Technique was effective in reducing adrenaline and cortisol levels within group comparisons.

    • "Meditation is a stress-reducing phenomenon that brings about " the relaxation response " by inducing favorable brainwaves and lowering the physiological and biochemical by-products of stress, such as lowered respiration rate, decreased heart rate, and lowered blood pressure (Lazar et al., 2000). Empirical evidence indicates that meditation is associated with reduced salivary cortisol levels, increased salivary total protein levels, lowered systolic and diastolic blood pressures, and reduced pulse rate (Sudsuang, Chentanez, & Veluvan, 1991; Walton et al., 2004). Brain imaging studies further specify the neurological impact of mediation practice on the brain. "

    ABSTRACT: Clinical challenges encountered by trauma survivors revolve primarily around (a) recognizing and differentiating current emotional experiences and physical cues from trauma-based responses and (b) learning how to regulate emotions and behaviors that allow beneficial fulfillment of needs and goals as defined by current life context and not past trauma. Meditation provides a different and complementary "technology" for conceptualizing and providing treatment to trauma survivors. By training clients to attend to the present, enhancing their ability to stay physiologically calm, and increasing positive emotions, meditation practice allows clients to manifest their internal resources to address the problems of trauma. This article discusses meditation practice for treating trauma survivors and describes the meditation experience of two clients to illustrate the potential benefits of meditation in their recovery process.
