How to stop cement from sweating in spring?

Actually, a dehumidifier does create heat. When we were first married and living in a small bottom floor apartment where there was a slab of concrete under the carpet, we heated the whole space with a dehumidifier. All those watts of energy that a dehumidifier consumes have to go somewhere.

I've also found a dehumidifier heats the space.

I wonder if there is a vapor barrier underneath that slab?

Would a whirly bird on the roof stop it?
