Is a sauna good or bad?
 

I've had a concussion for 3 months will a sauna worsen or make my head better, I'm allowed to run if that makes a difference

Being allowed and being good for you can be two different things.

At 3 months I could not have ran and I'm sure a sauna would not have been good for me either as temperature had a big impact on how I felt.

Trying new things (taking new steps) should be done in moderation until you know how it affects YOU.

Youngboii,

The sauna would not have a positive impact on your symptoms. It will stress your system.

What was your purpose for the sauna?

I sauna-ed from two months onward. The first few times I couldn't take it, but now it's part of my daily routine. Try it for five minutes and see how you feel.

If you do sauna, rinsing down with cold water afterwards can be very beneficial for circulation, including to the brain!
