Increase Endorphins
For those with depression or anxiety, taking a cold shower regularly may provide some health benefits like getting gentle electroshock therapy. The low temperature would stimulate more electrical impulses to the brain. As a result, it helps increase energy levels, clarity, and alertness. More importantly, cold water triggers the release of endorphins, which are also known as happiness hormones. This effect makes people feel more optimistic and cheerful. That’s why hydrotherapy has been increasingly becoming a popular treatment option for depression. [2]
Fight against Common Diseases
The immune system plays a key role in resisting foreign elements and preventing diseases. Some studies have shown that taking a cold shower on a regular basis may stimulate the production of leukocytes, a part of the immunity. This can help you deal with common illnesses better, such as the flu and colds. In addition, cold showers may actually help prevent several forms of cancer. Those who are going to have surgery or treatments for other diseases would take cold showers to improve their immune system. [3]
