A new study conducted by scientists at the University of Ottawa, Canada, has shown that immersing in cold water can improve cell health and slow down the aging process of the body.

The study, which was carried out on healthy young individuals, revealed that cold water immersion enhances the process of "autophagy," or more specifically, the recycling of cells to maintain their health and remove damaged cells.
The experiment involved 10 young men who immersed themselves in cold water at 14°C (57°F) for one hour each day over the course of a week. Blood samples were taken before and after the experiment.

The results showed that after exposure to extreme cold, there was a temporary disruption in the autophagy process. However, with continued exposure to cold during the week, the activity of this process increased, and markers of cell damage decreased.
Kelly King, the lead author of the study, explained that this suggests that acclimatizing to cold could help the body cope more efficiently with harsh environmental conditions. She expressed amazement at the speed with which the body adapted, adding that cold exposure could help prevent diseases and possibly even slow aging at the cellular level.
It is worth noting that cold water immersion has become a popular phenomenon in Canada, and this study provides scientific evidence of its benefits. The healthy activity of autophagy not only extends the lifespan of cells but may also protect against various diseases.
Professor Kelly emphasized that "This research highlights the importance of acclimatization programs to improve human health, especially in environments with extreme temperatures."
However, other researchers clarified that the results apply only to young, healthy men, and more studies are needed to confirm their effectiveness across other groups.
The study was published in the scientific journal Advanced Biology.
