Regular cold exposure, such as cold showers, ice baths and ocean swimming has risen in popularity in the last decade due to its many potential health benefits.
This extra attention on cold exposure has made it the focus of extensive research in recent years, with studies confirming its positive effect on a wide array of biological processes.
Below, I’ve summarised five key advantages of regular cold exposure and how these may impact longevity:
1 – Boosts Metabolism: Cold exposure stimulates the conversion of white fat to brown fat, which burns calories and generates heat.
Brown fat is a beneficial fat that is energy efficient and has a primary function of thermoregulation. Increasing brown fat stores improves metabolic health and aids in weight management, both crucial for longevity.
2 – Improves Circulation: Cold exposure causes blood vessels to constrict and then dilate, enhancing the circulation of oxygen-rich blood to vital organs, the brain, vasculature and the heart.
Cardiovascular health is a critical marker and determining factor of longevity, so any improvement in this correlates with an increased healthspan.
3 – Enhances White Blood Cell Production: Studies suggest that regular cold exposure may increase white blood cell production (a critical component of a strong immune system).
A resilient immune system prevents infections and chronic diseases, which can significantly impede longevity.
4 – Reduces Inflammation: Cold exposure reduces inflammation by decreasing the production of pro-inflammatory cytokines.
Perhaps the most potent advantage of cold exposure for longevity is its ability to reduce inflammation, a leading risk factor for organ failure, chronic diseases (such as heart disease) and Alzheimer’s disease.
5 – Increases Cellular Health: Studies show that cold exposure triggers the activation of heat shock proteins and other defence mechanisms that protect cells from damage and enhance cellular repair processes.
Cellular protection is a key factor in preventing the deterioration of tissues and organs and reducing the risk of age-related diseases.
This list demonstrates the rich and varied benefits that regular cold exposure has on biological systems (and how these may translate to a raft of potent longevity benefits).
