The Benefits of Cold Water Therapy

Cold Water Therapy has been scientifically proven to improve mental health, speed muscle recovery, increase physical performance, strengthen immunity and protect brain function, among other benefits. It also lowers stress, promotes weight loss, boosts energy levels, and improves circulation. Despite some negative reactions (like itchy welts from cold urticaria, according to the Mayo Clinic) and potential for hypothermia, this natural and easy-to-do therapy is safe for most people who practice it regularly.

However, it is important to note that cold water immersion can be stressful on the heart and blood vessels, so those with heart, blood pressure or circulatory problems should not jump into cold lakes or ice baths without checking with their doctors first. The key is to start low and slow—like dipping your toes into the pool or cold lake before diving in headfirst—and gradually build up your tolerance over time.

When the body is exposed to cold temperatures, the nervous system triggers a response that causes the blood vessels to constrict, which reduces inflammation and helps alleviate aches and pains. In one study, athletes who regularly took a cold-water plunge experienced less muscle soreness and more rapid post-workout recovery than those who did not.

This is especially important for those suffering from chronic or acute pain. Cold immersion also stimulates the release of the neurotransmitter norepinephrine, which can elevate mood and act as an antidepressant. You can try this simple therapy at home by taking regular cold showers or going for a cold swim in the winter months. The National Geographic show Limitless With Chris Hemsworth also showcased the benefits of this therapy when Hemsworth was challenged to go for a freezing swim in open water under medical supervision.
