The average American will spend over 500 workdays in the shower over a lifetime. But a simple 90-second trick can work wonders for your physical and mental health:

Step 1: Before you shut the water off, turn the


temperature down as low as it will go. Stay under the icy stream for 30 seconds. (Scream if necessary.)

Step 2: Turn the water up as hot as you can handle it. Stay under the hot water for 30 seconds.

Step 3: Switch the water back to cold for 30 more seconds. Then shut it off.

This hydrotherapy exercise will increase circulation… boost your immune system… increase your internal fat-burning mechanism… reduce stress… and battle depression. Not bad for 90 seconds of just standing there.
