This gives power shower a whole new meaning!
A study's found a cold shower can relieve stress.
According to researchers at Virginia Commonwealth University School of Medicine, cold water activates the sympathetic nervous system and increases beta-endorphin and noradrenaline in the brain. The latter is used in many anti-depressant medications.
Dr Nikolai Shevchuk discovered that people who take cold showers report improved mood, less stress and pain relief.
The recipe for a quick mood boost involves showering in cold water - around 20 degrees (a standard warm shower is 40 degrees) - for 2 to 3 minutes once or twice daily.
If that sounds too painful, try having your regular warm shower and turning it to cold for the last few seconds.
Brrrr to brilliant!
