As someone who wears a beard, I'd like to remind you and all others that body hair is a natural way to trap air and moisture near the body for a cooling effect. If you're shaving off your body hair, then you're defeating Mother Nature's most effective air conditioning, and you're going to ensure that your sweat slides uselessly down your legs before it can help your body cool down.

*mother natures most effective HAIR conditioning

I actually found here in Australia my legs felt cooler when they were shaven. Potentially because my legs have quite dark hair and therefore retain heat.

A very large number of males who are not genetically predisposed to the possession of any body hair and who happen to live in hot, humid, sometimes dusty as well as in extremely cold environments would like to remind you and to other proud owners of bushy beards and the hirsuteness overall that the body hair attributed to or induced «natural air-conditioning», «insulation», «protection from contaminants» is bunk armchair science.

Such naturally body hair devoid males also happen to live statistically significantly longer and healthier lives as well as outnumber the number of the said proudly hirsute males by a significant proportion.

As though living longer without a beard is somehow a good thing.

A beard is the facial hair, not the body hair. The beard hair is coarser, is longer, and the beard hair growth is regulated by different hormonal pathways. It is possible for an adult male to grow a beard whilst remaining completely body hair free.

I... have a beard and I was explicit about not shaving anything. Thanks for the "reminder," but:

Hey sorry, this does not happen.

I've spent many, many hours in the sun (sports, yard work, hiking) including in muggy 95F/35C+ summers over the years. There are days where I have consumed gallons of water just to replace what I've sweated out.

Wouldn't exactly be hard to detect. If it was literally running down my legs with no chance to evaporate then it would be pooling in my socks and shoes or leaving trails of sweat on the tennis court. Never seen this happen to me or anybody else in person or on TV. And certainly you don't see this on televised sports. You don't see leg hair-less people passing out or dripping sweat onto the playing surfaces in basketball, tennis, etc.

Body hair may serve other sorts of cooling purposes. Certainly the hair on our heads (if we're lucky enough to have it) protects us from the sun. And thick enough body hair may do that as well. Really not buying the sweat thing though.

I shaved my legs for years, being a woman because society expects me to. Since I have stopped shaving ( having two full legs of stubble every day is a chore and uncomfortable) I noticed my legs sweat less and are way more comfortable, not to mention no razor burn, no ingrown hair, no prickly missed stubble because I was in a hurry and no more heat rash which I would frequently get on my thighs. Guess we have hair on our legs for a reason, imagine that.
