I'm sorry I've been too busy to write much lately. Here's a quick tidbit for the one or two of you who check here daily and may be wondering where I am. (Thank you, loyal reader!)
Here's an article that debunks some common medical myths. I don't know as I believe everything they say (I mean, what parent hasn't seen a child go crazy after eating lots of sugar?), but here's an interesting take on the idea that it's important to wear a hat because we lose most of our body heat through our heads.
Interesting. I'm keeping my winter hat, though; there are times when I need that 10%.[T]he US Army Field manual for survival recommends covering your head in cold weather because around 40-45% of body heat is lost through the head. A recent study, however, showed there is nothing special about heat loss from the head - any uncovered part of the body would lose heat. Scrutiny of the literature shows this myth probably originated with an old military study in which scientists put individuals in arctic survival suits (but with no hat) and measured their body temperature in extreme conditions. If the experiment had been done with the participants wearing only swimsuits they would not have lost more than 10% of their body heat through their heads, the researchers said.
