Is there such thing as getting a rash from sweating?

I woke up this morning with whitish bumps on my upper back and on the back of my arms. I haven't used any different products, or eaten anything different so it's not an allergic reaction. I was sweating a lot in my sleep last night for some reason so it's the only thing I can think of. It doesn't really itch too much. It's just weird. Can it be from sweating?

I think it can be from sweating.  I get all kinds of weird rashes, when I am sweating, when I am hot, when I am nervous.  If it starts itching and doesn't heal in a few days I would go have it looked at though.

Yes it is possible. My brother gets this.
