Analgesic Effect: The Benefits of Cold-Water Immersion
A study conducted in 2012 revealed that cold-water immersion can effectively reduce soreness, inflammation, and constrict blood vessels following an intense workout. However, a more recent research conducted in 2017 found no evidence to support the claim that cold-water immersion therapies contribute to faster functional recovery and improved performance among athletes. Nevertheless, this hydrotherapy still offers potential benefits, as it can help alleviate muscle soreness and provide analgesic effects similar to that of a placebo.
Relieves Certain Symptoms of Depression
Scientific research has indicated that subjecting oneself to cold temperatures can stimulate the sympathetic nervous system, responsible for regulating heart rate, blood pressure, and other bodily functions. This activation leads to a rise in endorphin levels in the bloodstream, which can have a positive impact on mood. Cold showers, in particular, can be effective in this regard due to the high concentration of cold receptors in the skin. As a result, the peripheral nerve endings send a greater number of electrical impulses to the brain, potentially producing an anti-depressive effect.
