Research has shown that cold showers can have multiple health benefits. For example, a cold shower can help with blood circulation, muscle soreness after intense workouts, itchy skin, etc. Mental health conditions (such as anxiety and depression) may also benefit from taking a cold shower. Cold showers are also considered an easy and accessible at-home version of hydrotherapy. Hydrotherapy is a form of therapy that uses water (whether hot or cold) to treat a number of symptoms and conditions. Many people state that they feel more alert, clear-headed, and energized after taking a plunge in cold water. As a result, people feel like they have a firmer grip over their stress, anxiety, and/or depression.
