Cold water constricts your blood vessels, which produces a short-lived feeling of alertness. It has never been proven to have any health benefits.

If you want to feel more alert for the next hour or so, take a cold shower. If you're trying to improve your health, don't bother.

Dumb and stupid. You're just destroying your body.

True.

>It has never been proven to have any health benefits.
Imagine thinking that being in a state of fight and flight constantly spiking cortisol is a healthy thing, lol

I advice against it, unless he is trying to deteriorate his health and cause early dementia.

They're unnecessary & overhyped. If you do them at night they'll keep you awake & even fuck with your sleep. Doing them in the morning will keep you alert for a short period.
Like >>34583962 says, don't bother.
Lukewarm showers are best in my opinion.

They fuck with your sleep if you take them in the evening, can confirm when I used to try them after having a hot shower. Lukewarm showers are best.
