The contrast shower protocol, created by Ray Cronise, a former NASA material scientist, is:
10 sec warm water, 20 sec cold water. Repeat 10 times. End on cold. Five minutes in total. Some benefits experienced by followers include:
- Boosted energy
- Lifted mood
- Higher fat burning rate This timer app implements the protocol and speaks cues to switch between warm and cold water and lets you track the progress - "Warm. beep beep ... Cold. beep beep ... Warm. beep beep ... Cold. beep beep ... One minute done ... ...... Congratulations! You just finished a five-minute contrast shower. Have a good one!" Happy contrast showering!
