Re: Can Wet Hair Cause Cold/Flu?
Though going outside with wet hair cannot CAUSE a cold or flu, it can put a strain on your body if it is cold oustide. When your body has to fight too hard to stay warm it lowers your resistances and that's when colds and flues are most likely to be caught. Basically, it is better not to go outside with wet hair when it is cold.
According to one form of alternate medicine (Ayurveda) going outside with wet hair can cause sinus problems. Though this may not be true in the Western sense, if you look carefully, you can see the logic. A lot of heat esapes through the head. When the hair is wet, your more apt to lose more heat. This in turn would overwork your body. Because your sinuses are in your head, I'm sure they would over produce mucous and that may be what you are experiencing. This is just my theory on it.
Sometimes, it is wise to heed old wivestales as silly as they may seem with our science. There may be some logic behind these old beliefs.
