Plunge Pools are an excellent way of cooling down after a heat treatment. Plunge pools accompany spas, saunas or steam rooms to enjoy the sensation of going from an intensely warm environment to a chilly environment in a matter of seconds. By rapidly cooling the body, blood circulation is stimulated, pores are closed and detoxified. Plunge pools also numb the joints, and are effective in reducing pain, relieving muscle spasms and help minimize muscle inflammation.
