Abstract

Aging is a multifaceted biological process characterized by a progressive decline in physiological functions and heightened vulnerability to diseases, shaped by genetic, environmental, and lifestyle factors. Among these, cold exposure has garnered interest for its potential anti-aging benefits. This review examines the impact of cold exposure on aging, focusing on key physiological processes such as inflammation, oxidative stress, metabolic regulation, and cardiovascular health. Cold exposure has been shown to reduce chronic inflammation, enhance antioxidant defenses, and improve metabolic health by activating brown adipose tissue. Furthermore, findings from hibernating mammals and model organisms suggest a connection between lower environmental temperatures and increased longevity. However, the potential long-term health risks of extended cold exposure, particularly in older adults, remain a significant concern. Epidemiological studies reveal increased rates of mortality and morbidity in populations living in cold climates, emphasizing the complexity of the relationship between cold exposure and aging. This review underscores the need for further research to elucidate the long-term effects of cold exposure on aging and to establish guidelines for leveraging its benefits while mitigating cold-induced risks.

期刊介绍： Life Sciences is an international journal publishing articles that emphasize the molecular, cellular, and functional basis of therapy. The journal emphasizes the understanding of mechanism that is relevant to all aspects of human disease and translation to patients. All articles are rigorously reviewed. The Journal favors publication of full-length papers where modern scientific technologies are used to explain molecular, cellular and physiological mechanisms. Articles that merely report observations are rarely accepted. Recommendations from the Declaration of Helsinki or NIH guidelines for care and use of laboratory animals must be adhered to. Articles should be written at a level accessible to readers who are non-specialists in the topic of the article themselves, but who are interested in the research. The Journal welcomes reviews on topics of wide interest to investigators in the life sciences. We particularly encourage submission of brief, focused reviews containing high-quality artwork and require the use of mechanistic summary diagrams.
