The findings make sense to me. I get uncontrollably tired whenever there is a hurricane on its way. I figured out a while back that this is due to the unusually low pressure associated with these storms. I have sensitive hearing and somehow whatever mechanism accounts for my acute hearing also seems to respond to low pressure. Other people do not seem to get tired from low pressure the way I do and seem to think I’m a bit crazy for needing to conk out in the middle of every tropical storm and hurricane. I’m not sure how the whole inner ear pressure thing might make me sleepy, but sometimes I notice a full feeling in my ears when I am tired.
