A guy I am crushing on was complaining today that on rainy days, he feels like absolute crap - extremely exhausted and drained. I speculated that it might be related to the barometric pressure which gives lots of people headaches. Anyway, he is coming to see me as a sage in all things body/diet related so wanted to know if there was anything he could take to counteract this. Or does it indicate a low-level deficiency he needs to address, i.e. vit D? He's not Paleo (yet) but isn't the worst eater, either, and not fat. Body of Adonis, actually.
Hmm. Pressure changes and clouds can trigger the seasonal disorder--isn't that using the acronym SAD also?--and migraine. I don't know of a relief solution for the migraine but if anyone offers one here I'll use it. For SAD, I think some people are trying full spectrum lighting to simulate sunshine.
For me, I get a similar situation due to an Eustachian tube problem. Get migraines around times when it is really windy/rainy. Odd thing is it doesn't seem to happen in planes or driving up mountains. I usually end up taking something like Excedrin. Can't really tell if Paleo helped or not (you'd think it would due to being less inflammatory). Doesn't rain much around me, and hasn't been truly windy in a while.
Other possibility is SAD like others have mentioned. However, for me, the migraine is plenty enough to make me feel exhausted/drained. It keeps me up at night.
