It used to be a joke to tell someone to take a cold shower when either their temper or their passions were getting the best of them, but there are also some health benefits to a cooler shower -- including that it boosts your immunity.
Certified fitness and wellness coach Emma Caird tellsReal Simplethat a cold shower can increase white blood cells, which battle disease and infection. Dr. Amber O’Brien adds that the cool rush of water is also good for your mental health, reducing stress and anxiety. There are other benefits to a cold shower, including increasing your focus and energy levels. But it’s important to know you don’t have to jump right into an icy shower to receive the perks. Start by reducing the temperature gradually at the end of the shower for a few seconds. Add a few more seconds every time.
