The National Library of Medicine (NLM) has done several studies about cold immersion and ice baths in great detail and their findings highlight various scientifically-backed benefits.

One study found that athletes who took ice baths after exercise experienced less muscle soreness and were able to train longer following the ice bath. Similarly, two studies from other sources, one in 2016 and one in 2011, discovered that cyclists experienced less soreness after soaking in cold water for 10 minutes.

Another NLM study, found that cold water exposure creates an “immunostimulating” effect which basically means it stimulates your immune response. Multiple studies have proven that regular cold showers can boost one’s immune system and lower inflammation and anxiety levels. A Science Direct study showed improvement of depression symptoms after several weeks of hydrotherapy.
