An office that is too warm

Short answer: Change the innermost layer to something that moves moisture, and put the outermost one away. A warm office is mostly about moisture against the skin.

What actually bothers you

It is rarely the temperature alone. It is the sweat that stays in a cotton shirt and makes the fabric clammy against your back after a couple of hours.

The change that works

A thin undershirt in bamboo viscose under the shirt moves the moisture away from the skin and into the fabric where it evaporates. It feels cooler even though there is one more layer. See bamboo undershirts for men.

The other measures

A looser shirt, rolled up sleeves and a bottle of water on the desk. See bamboo shirts for men and bamboo t-shirts for women.

Frequently asked questions

Is one layer fewer better

Not always. A layer that absorbs moisture beats bare skin inside a shirt.

Why do you sweat most on your back

Because the chair back blocks the air that would otherwise cool you.

Does a desk fan help

Yes, moving air evaporates sweat faster.
