The thought of stepping into ice cold water can be intimidating. But, cold exposure is shown to be great for you in a variety of ways. Research shows it can boost your metabolism and reduce inflammation and stress. It can also improve your sleep quality and focus, and increase your energy levels. Like exercising, cold exposure puts a healthy amount of stress on your body that your body then has to overcome, making it stronger in the long run. And it causes you to release natural painkillers, such as endorphins, that are pleasurable as well. And you can take it slow—start by stepping into mildly cold water, and make it a little colder each time you shower. And stay in a little longer each time. It will get easier and easier over time. It’s a health tool that is fast, cheap, and effective!
