How Cold Water Immersion Can Alter Your Cells' Functioning

A recent study has shown that frequent cold water immersion can boost autophagy, maintaining cellular homeostasis and energy levels. Autophagy is the process by which cells break down and recycle damaged or excess proteins and organelles. A study conducted by the University of Ottawa found that daily one-hour cold water immersions over a week can alter cell functioning and enhance cold tolerance. Ten healthy young men participated in the study, immersing in cold water at 57.2°C for an hour each day. "Our results suggest that repeated cold exposure significantly enhances autophagic function, a crucial cellular protective mechanism; this enhancement enables cells to better cope with stress and could have significant implications for health and longevity," explained study co-author Glen Kenny. The researchers emphasized that repeated exposure to such temperatures could greatly contribute to preventing various diseases. However, they noted that the effects of cold water immersion only last three months post-immersion. As cold water immersions are becoming increasingly popular, the research team urges participants to understand the impacts on cellular mechanisms. Significant improvements were also observed in terms of fatigue, sleep, skin health, and immunity. Since the study focused on the male population, further research on the effects of cold water immersion on other population groups is necessary.
