6. Eases Stress
Jumping into the shower without letting it heat up, or going into the ocean without slowly acclimating to it, can help promote hardening, increasing tolerance to stress, and even disease. A 1994 study found a drastic decrease in uric acid levels during and following exposure to a cold stimulus. There was also an increase in gluthathione, an antioxidant that keeps all other antioxidants performing at their optimal levels. The participants, who were 10 healthy people who swam regularly in ice-cold water during the winter, adapted to repeated oxidative stress.
7. Relieves Depression
Cold showers have been shown to relieve depression symptoms due to the intense impact of cold receptors in the skin, which send an overwhelming amount of electrical impulses from the peripheral nerve endings to the brain. Thus, it produces an antidepressive effect, and boosts moods, making it a pick-me-up. A 2008 study found that cold hydrotherapy has an analgesic effect, and does not appear to have noticeable side effects or cause dependence. This treatment included one to two cold showers of 38 degrees Fahrenheit, two to three minutes long, followed by a five-minute gradual adaptation to make the procedure less shocking.
It’s time to take a duck to water, and try the benefits of hydrotherapy.
