the body. A study of people aged 85 to 110 showed that low inflammation levels predicted survival and cognitive function. Reducing inflammation could therefore prolong life and lower the risk of chronic diseases.
Norepinephrine inhibits inflammatory pathways by decreasing levels of TNF-alpha, a protein implicated in almost all human diseases. It also reduces other inflammatory molecules such as MIP-1 alpha. Furthermore, by lowering body temperature, blood vessels constrict, which can help reduce inflammatory markers.
Boosting immunity
Another surprising benefit of cold showers is improved immunity. One study showed that immersion
