luckily I had not done login, otherwise you felt my laughter when I read phone (I was talking about hair dryer ...)

I think sudo in your language you say sweat.
I think that our headache 95% is caused by taking cold or wind in it, the most vulnerable areas are: the side (above and behind the ear) and the neck;
if you are sweaty in those areas and you are exposed to wind and cold headache is first and strongest.
Mesci thanks for giving me the opportunity to explain ...
