Most people who experience a whole body cryotherapy session report that they are in a better mood and have higher energy.  Some European studies show that clients have less anxiety/depression after cryotherapy – this may be due to an increase in endorphins.  Endorphins are chemicals released by the brain which blocks pain perception and may elicit the feeling of euphoria.  On a physical level, cryotherapy has been shown to increase connective tissue growth.  This helps athletes recover from injuries and it may help alleviate symptoms from arthritis, tendinitis, and chronic pain.  However, cryotherapy is not appropriate for people with liver disease and other health conditions, see list below.
