Why do i be aware of so tired when its a changeable daylight?

is there a medical defence for this?Why do i be aware of so tired when its a changeable daylight?
thats actually somewhat true, because on 4th of july, absolutly no one be leaving their house because it be really gloomy and everyone be tired. a few reasons i could chew over of was that the miserable weather makes it be aware of somewhat like dark and made people tired. as resourcefully as there be alot of allergens in the atmosphere, and sometimes allergies can make you sleepy. but thats of late my guess.
yes the sun gives you vit D which give you energy and on changeable days you dont get as much as when it is sunny
