What are these tiny bumps on my skin called? could they be from sweating in the sauna?

Where are they?: If on upper arms, they are called keratosis pilaris (sometimes seen on upper legs too). If elsewhere, you'll need to see a dermatologist to get precise diagnosis. Doubt that it's due to sweating in a sauna, regardless of what it is.
