In recent years, cold water therapy, which includes immersion in cold water or cold showers, has become an increasing health trend among athletes. Despite its widespread popularity, scientists have begun to question the effectiveness of this therapy in improving general health.
To answer these questions, a group of researchers at the University of South Australia conducted a comprehensive study aimed at evaluating the health benefits of cold water therapy. The results of the study showed that this practice may be beneficial, but it also carries some limitations that must be taken into consideration. Analyzing the effects of cold water therapy. Researchers used data from 11 studies involving 3,177 participants to analyze the effects of cold water therapy on stress levels, sleep quality, and overall quality of life. The results found that immersion in cold water may help temporarily relieve stress, but the benefits are short-lived and depend heavily on the context. Tara Kain, a researcher at the University of South Australia, says: "Although cold water therapy is widely accepted in the sports community, its effects on the general public are still not fully understood." Relieving stress and improving sleep. The study showed that immersion in cold water can reduce stress levels for up to 12 hours. Participants who included cold showers in their daily routine also reported a slight improvement in their quality of life, with showers lasting between 20 and 90 seconds. However, the researchers noted that these benefits fade after 3 months, indicating that continuity may be the decisive factor in achieving sustainable results. Regarding other health effects, it was shown that regular cold showers may reduce the number of days off work due to illness, as one study showed a 29 percent reduction in the number of days lost due to illness. However, this result raises questions about the mechanisms that lead to this effect, and whether these results apply to everyone or only to specific groups. Inflammatory response: a tool for adaptation. Dr. Ben Singh, one of the researchers in the study, pointed out that cold water therapy causes a temporary increase in inflammation, which may seem contradictory given the use of ice baths to reduce inflammation after exercise. However, this inflammatory response is part of the body's reaction to the cold, and can help the body adapt and heal in the long run. Caution for those with chronic diseases. Despite the promising results, the researchers warned that cold water therapy may pose risks to people suffering from chronic diseases or other health conditions, as the temporary increase in inflammation may negatively affect their health. Dr. Singh said: "People with chronic health conditions should be cautious when trying cold water therapy, as the initial inflammation may have negative effects on their health." (Sky News)
