Dry air also increases the probability of static damage. They probably can't use outside air exchange to cool the server room.

I imagine just circulating your nice toasty air into a larger area filled with moist humans who want to be warmer would work, but it depends on your building layout.

Static damage? Where I was raised, winter temps regularly reached -40. That cold, outside air already had most of the moisture 'wrung out of it'. Now let that cold dry air into the house and warm it: the relative humidity plummets.

Now walk across a carpet in leather-soled shoes. Do NOT even touch metal doorknobs, let alone metal faucets!

A favorite game of my siblings and I during the winter growing up in Minnesota was to shuffle across the floor and then poke each other.

In the winter (in MN), I usually wake up to my dog shocking us nose-to-nose while he checks if I'm still sleeping.

I'm kind of surprised he hasn't been trained out of this from the pain/surprise. Seems like sort of a shock collar effect.
