The benefits of cold showers include increased endorphins, lower chances of depression, improved metabolism, improved circulation, better resistance to common illnesses, reduced pain, an elevated respiratory rate, increased alertness, an increased ability to wake up in the morning, faster physical recovery, reduced muscle soreness, healthier hair and scalp, healthier skin, and a boosted overall mood.
Most people prefer hot showers because they are more enjoyable, and hot showers also have a number of benefits. However, when it comes to physical and mental health, cold showers prove much better for you than hot showers.
Cold showers can increase the number of endorphins someone has as well as serve as a type of antidepressant. The human body’s many cold receptors, and during cold showers, these receptors are activated quickly and end up sending overwhelming amounts of electrical impulses to the brain, which results in insane levels of stimulation in the nerves in the brain, leading to many endorphins being released and an overall feel-good effect. This leads to an improved mood and reduced chances of depression. Additionally, a clinical trial found that taking a cold shower for 5 minutes, 2 or 3 days a week can help relieve symptoms of depression.
Cold showers can also improve metabolism because while in these cold conditions, the body has to work harder to maintain a stable body temperature. This improves the metabolism and can help with weight loss, though it shouldn’t be relied on to lose weight. Your circulatory system can also be improved by taking cold showers for a similar reason to the metabolism improvements as the body must work harder to pump blood and in turn becomes stronger.
Cold showers can also improve the ability to fight common illnesses because the cold waters shocks and stimulates the blood cells designed to fight off infection (called leukocytes). According to the National Libary of Medicine (NLM) - The United States national database of medical information - a study conducted in the Netherlands called the “cool challenge” found that people who switched to cold showers for 90 days called in sick from work 29% less than people who took hot showers. So obviously, this stimulation of blood cells has a noticeable effect on the body’s ability to fight common illnesses.
There is also evidence that cold showers can have anesthetic-like effects on the body, meaning pain relief. An article written in the North American Journal of Medical Sciences found that exposure to cold water can cause constriction of the blood vessels, which can help reduce swelling and edema, which cause pain. The cold can also slow the speed by which nerve signals conduct pain impulses. And while cold showers shouldn’t be solely relied on as anesthesia, they can reduce general pain and discomfort.
Increased alertness can also be a result of the shock brought on by cold showers because it stimulates nerves and the brain, and this combined with a higher respiratory rate (touched on earlier) can make it easier to wake up in the morning as an additional result of cold showers.
Because of the regenerative properties of the cold water and the stimulation of the cells and nerves, cold showers can support muscular relaxation, reduce muscle soreness, and improve the ability of your muscles to repair themselves after high exertion.
