The look at different tribal people from dfferent climates and different traditional cultures and indegenous cultures, shows that some has more ans some has nearly no body hair.

In modern times shaving is very common even under traditional cultures. The use of iron blade are include in a lot cultures.

Asian people are known for less body hair. Excluding the typical yogi guru whith full beard and some chest hair. Meditarianian people and arabic middle east people have lot of body hair also in central europe people have natural more body hair. And hair loss is common also in old days in central europe. Maybe not in paleotimes?

Inuit people of the north also have less facial and less body hair.

Is there a rule or fomrula for less body hair or much body hair. There was a documentry on skin colour and vitamin D through the sun. They also mentioned body hair. They somehow combined it with the walking straight and different temperature of the body.

What do you know on hair?

i actually heard the opposite; humans lost body hair to improve cooling. therefore; less hair=increased cooling. my understanding is that in land based mammals covered with hair, water evaporation (cooling) via sweating is not very efficient, hence panting and saliva spreading (or jumping in some water for cooling etc)

I think balding has to do with high testosterone, and balding isn't an illness or physical impairment, just something we have social perceptions about.

I know eating a paleo diet made my body hair much sparser and finer, and is helping my head hair to grow back in thicker after a couple years of chronic telogen effluvium...

Easy, Higher testoterone levels lead to less body hair. high estrogen and low T leads to increased DHT which cause body hair growth. this is why most caucasians get hairie (and balder) as they age, it has to do with the high estrogens involved in eating vegetables and grains. some ethnicities have higher Tesosterone levels then others, American Indians and Asians in particular. Meat raises Testosterone.

My guess is body hair relates more to the need for evaporation than anything due to dietary differences. Those from dry climates sweat more than those from humid climates, as the ability to cool the body through sweating is favored in desert climates of all temperatures. Body hair provides more surface area to speed the cooling process. In addition hair provides 'lubrication' at friction points.

I've also found that after I turned 35 my body hair lightened significantly, so maybe some of you are experiencing normal aging.

Being a real-life chewbacca of Germanic and Celtic descent, I am interested in the answers... I have nothing else to offer, except that I know people who have spent their lives in the sun eating a natural (WAPF) type diet (no lack of Vit. D) and still grew to be bald.
