Stormy = Sleepy?

Over the weekend, it was a bit cloudy and even rained a little. It was pretty much a mucky day. I felt the same feeling I do every time it's like this: I feel really lazy and tired, and the last thing I want to do is move.












Why does this happen? I asked a couple of friends to see if this was just me, and it isn't. Many people feel this way on a crappy day. I wonder how the weather changes the energy level in our bodies. Why am I so tired on days like these?

I decided to look it up. Google says that low light conditions of the storm can lead to a spike in melatonin, which helps control your sleep and wake cycles, therefore making you feel quite drowsy. I think that is super cool.
