Depressed? Try a Cold Shower
It’s just a theory so far, but worth a try if you’re up for it: A cold shower might be just the trick to shock your brain out of a depressed mood.
I stumbled upon a decade-old article this week detailing a hypothesis along these lines. It points out that modern humans in our comparatively luxurious environments are largely missing out on something primates have experienced for millions of years: Cold shocks.
Heated water might be robbing us of a the “thermal exercise” we need for our brains to function adequately.
The hypothesis seems reasonable. We know exposure to cold activates a release of beta-endorphin and norepinephrine, both of which play important roles in boosting mood. And because there are so many cold receptors in the skin, a cold shower would send tons of electrical impulses to the brain. The article’s author says this could overwhelm the brain and result in an anti-depressive effect.
So give it a try next time you’re feeling depressed. It may give you just the boost you need!
