There are advantages to cooling the body, at least externally – just like using an icepack on a swelling or injury. One of the idea behind using cryotherapy for athletes is that it can help with post-training recovery by preventing muscles and joints from swelling due to damage during training.
Hypothermia is when your core body temperature begins to drop, and requires prolonged exposure to cold. A cryotherapy session is measured in minutes and you’re monitored during that time so hypothermia doesn’t develop.
