– If air temperature is consistent in a room, why does air from a room fan feel cool on our skin? It’s the same air with the same temp… just faster
In: Biology
I would say it’s partly mental but also some science to it.
Mental, because your brain automatically connects air flow to “cool breeze” so it feels better.
Scientifically I would say that your body is constantly radiating heat. Meaning there is a bubble of heat around your body that eventually dissipates/cools. As air blows over your skin, that heat is being pulled away from your body, rather than just idly radiating the heat away, which cools you down more/faster.
A facilities manager (maintenance guy) for a business I used to work at always got complaints about how hot it is in the offices. The temp was always at 70 during the day, and a lot of folks would dress appropriately if they were too cold, such as pants and sweaters. The manager would turn up fan speed a little bit, rather than drop the temperature, and the ones complaining were happier.
