Athletes and fitness enthusiasts alike have taken up ice water baths as an immediate form of post-workout recovery. Ice baths, also known as cold water immersion (CWI) or loosely referred to as a form of whole body cryotherapy, entails submerging yourself in a vessel of cold water (roughly 50-59 degrees) after vigorous workouts or exposure to high heat such as a sauna, steam room or hot bath. 

The act of meditation has been around for centuries with rich origins in countries like Japan, India and China. In the last decade, it has become increasingly popular in the US for the positive effects on both mental and physical health. In fact, the amount of people who practice meditation has more than tripled from 2012 to 2017. 

While the practice of hot yoga cannot be traced back and attributed specifically to an individual or group, the use of heat can be attributed to many cultures and spiritual classes for centuries as a form of healing and cleansing.
