Weather

Yes that is right our mood those change acording to the weather. I really have no idea why but those happen to me wether some times might make me sleppy or awake, sad or happy. I guess that it also has something to do with how we might be fealing at that moment. Lets say we are a little sad and it stars raining you might just burst into tear. I don't know why but it is a little weird. well happy mylotting

It's a combination of a few things. The low light is part of it, also the lowered air pressure (which is also what causes the "smell of rain" that comes before and after a storm). And the sun give us vitamins, especially vitamin K which we can get from some foods but in nowhere near the amount as we get from 20 minutes out in the sun.
