Is it safe for the brain? What about saunas? Because I read somwhere that heathstroke and hyphotermia is bad for the brain.
In the sauna you shouldnt sray longer than 15 minutes at once. Also if your lungs are birning or you feel light headed maybe go out. Otherwise it's safe if the temperature is measured. A cold shower after the sauna is so good.
As for cold showers you won't go into a shock or anything if it's not freezing water. Start by wetting your toes and then go straight for the head. A quick cold shower is really refreshing for some people.

Both Saunas and Cold Showers are perfectly safe
Hypothermia and Heatstroke are extremes to where you're actually dying, you'll know when you're close to even coming close to either.
Just don't do anything dumb like "who can stay in the sauna/ice bath the longest!"
