Immersion in cold water, from immersion in the winter ocean to the adoption of ice baths and bathing in the hole, is becoming more and more popular among athletes and lovers of a healthy lifestyle, but its benefit remains under close scientific attention. In a systematic review and meta analysis conducted by researchers from the University of South Australia (Unisa), its influence on health and well-being and scientists learned several interesting nuances, writes University of South Australia.

Scientists analyzed data 11 studies with the participation of 3,177 people. The results they obtained, published in the PLOS One journal, indicate that immersion in cold water can temporarily reduce stress, improve sleep and improve the quality of life, but its effect is often short -term and depends on the context. Researcher at the University of South Australia and the author of the study, Tara Kane, emphasized the nuances of the study, in particular, the dependence of the benefit of immersion in cold water from time.

The analysis showed that the decrease in stress lasted only about 12 hours after immersion, and a slight improvement in the quality of life was noted by participants who took a cold shower within 20, 60 or 90 seconds, although these advantages disappeared after three months after. In addition, one study showed that in people who regularly take a cold shower, the number of diseases of illness was reduced by 29%. However, the allegations that immersion in cold water significantly increases immunity or mood, do not have significant evidence.

The study of scientists was devoted to immersion in water with a temperature of 10-15 degrees Celsius at chest level or higher, including methods such as cold shower, ice baths and immersion in the ice hole. It is interesting that although the immersion itself in cold water is widely used by athletes to reduce inflammation and soreness of the muscles, one of the researchers, Dr. Ben Singh, noted that at first it causes a temporary surge in inflammation.

Singh explained that such a short -term reaction is a way of the body to adapt to stress, just as physical exercises first damage the muscles and then strengthen them. Given this effect, people with existing diseases should be cautioned, since the initial inflammatory reaction may have negative health consequences.

Although some data confirm the short -term benefit of immersion in cold water, its long -term consequences remain unclear. The study emphasizes that most of the information is obtained from men, which limits their wider applicability on all. In addition, many allegations of increasing immunity and a steady improvement of mood do not have confirmed scientific justification.

Researchers emphasize the need to carry out further long -term work among various groups of the population in order to determine who gets the greatest benefit from immersion in cold water and optimal conditions for its use. Cold impact as wellness practice is gaining momentum around the world. However, scientific research is still ambiguous in relation to its long-term influence.
