Cryo machines use liquid nitrogen which is then vaporized. When this vaporized liquid nitrogen touches your skin, your skin temperature will drop between 40-70 degrees Fahrenheit in a short amount of time. Usually, this time takes about 2-3 minutes. Our skin will react to the cold temperature which then sends a message to the brain. This will stimulate regulatory functions in the body and assist areas that might not be working to their fullest potential. Thermoreceptors in the skin send signals to the brain to send the blood to the core to maintain body temperatures with a process called vasoconstriction. Toxins are then flushed away from peripheral tissues. Your blood is enriched with oxygen, enzymes, and nutrients. Your body will activate natural healing abilities to release endorphins will which further benefit you.
