High magnetic fields are unique artificial physical environments. Since 1913, more than 10 Nobel prizes were given to novel findings related to high magnetic fields in the areas of high-temperature superconductivity, new materials, and life sciences. In recent years, progress in superconducting technologies has dramatically enhanced the application of high magnetic fields in scientific research, industry, and healthcare. Many countries have established national-level high magnetic research centers to strengthen scientific research in magnetic fields. The National High Magnetic Field Laboratory at Florida State University in the United States, the Grenoble High Magnetic Field Laboratory in France, the High Field Magnet Laboratory in Nijmegen in Netherlands, the Tsukuba Magnet Laboratory in Japan, and the High Magnetic Field Laboratory of the Chinese Academy of Sciences in China are the most recognized magnetic field research centers worldwide. Of these institutions, the High Magnetic Field Laboratory in China has a unique research team focused on magnetic field life science research. Current progress at Chinese institutions in high-level talent teams, scientific research, and industry applications is significant and has achieved considerable international influence. In April 2018, the 620th session of the Xiangshan Science Conference, "High Magnetic Field and Life Health: New Conditions, New Questions, New Opportunities", was held in Beijing. This conference attracted more than 40 participants from approximately 30 domestic and international institutions. The following central issues were discussed at the conference: (1) the theory and techniques of high magnetic equipment based on novel superconductive materials; (2) fundamental life science research under high magnetic fields; (3) magnetic nanoparticle medication and iron metabolism; and (4) applications of dynamic magnetic fields in human health care and medicine. The present paper offers a comprehensive summary of the opinions, views, and visions collected during this conference. In addition, this paper reviews recent progress in the interdisciplinary field of high magnetic fields and life science and healthcare. For each central issue discussed in the 620th session of the Xiangshan Science Conference, this review gives a brief summary of the current advancements and challenging problems in research. The key scientific questions and application techniques in this field and the strategic thinking and landscape planning of the scientific research are promoted. Several unknown questions and future directions of innovative and featured research are identified in this paper. First, the scientific questions in the field need to be refined. Moreover, it is necessary to consider how to achieve scientific breakthroughs and high-level scientific research results with the scientific and technical advantages that currently exist in China. Second, the translation-oriented interdisciplinary scientific research in this field needs to be one of the primary research directions to produce innovative principles, methods, and technologies for healthcare and medical treatments. Third, the cooperation of the research groups in China needs to be enhanced to advance the fundamental and application research of life sciences, health, and medical care with respect to high magnetic fields.
