"Randy, do you have to go to the bathroom?" "Not anymore...."

It's winter time. Or, it will be tomorrow. But I don't do odd on the weekends, so today will have to do.

And, because it's winter time, it's also cold. So, to fight the cold, we bundle up. And, we always wear a hat when it's cold because we lose most of our body heat through our heads.

Mom's have been telling kids that for years. heck, the local new's keeps telling people that. And the sad part is, the believe it.

But it's not true.

In the 1970's the 'fact' that you lose 40-45% of your body heat through your head started being spread around. (some said it was as high as 90%). Teachers in school taught it, the neighbors told you, your friends moms told you. I was a kid growing up in the 70's, and if I dared to not wear a hat, and it was below 40, you got told!

So, where did this information come from?

In the 1950's, the US Army was looking at improving their cold weather gear. (winters in Korea were cold.) So, they put soldiers in arctic wear and had them stand out in the cold. Their pants, jackets, boot and gloves all did a fine job. However, every single man reported their heads were cold.

It doesn't take a genius to realize then, that the head is where most of the heat escapes, and hats should be worn.

When the soldiers put on hats and stood out in the cold, they reported warm heads. The scientific conclusion the Army came to, and published in an extensive report was: wear a hat.

There's just one slight problem with the study the army did. And by slight problem, I really mean one major problem. When they had the soldiers originally stand in the cold, they were wearing full arctic gear, except, no hats. Their heads were totally exposed.

Gee, I wonder how they came to the conclusion that you lose most of your body heat through your head?

Since then, more studies have been done. It's been shown that heat escapes from your head at the same rate as the rest of your body. In fact, if you were to stand in the snow wearing only a Speedo, you'd only lose about 10% of your heat through your head.

Exposed skin is where you lose heat, not just the head. So, keep it bundled out there. otherwise, I'll call the army and have them get all scientifically experimental on your ass.
