Hydrotherapy, referred to as the ‘Water Cure’ in the 1800s, is the use of water to maintain health.
One method of hydrotherapy is the provision of contrast (i.e. applying hot then cold water to the area) to increase blood flow to and through the area. Some practitioners suggest it supports pain relief by stimulating endorphins and increasing circulation through an inflamed area.
The procedure (using your arm as an example) is as follows:
(1) Shower the arm and hand with water that is as hot as you can comfortably handle, working from the hand up to the shoulder and back down to the hand. Do this for 1-minute.
(2) Adjust the temperature to cold and shower your arm and hand with cold water, working from the hand up to the shoulder and back down to the hand. Do this for 30-seconds.
(3) Repeat step 1 and then step 2 for a further 6 times.
