Sleep and Exercise (and small spaces?) (23)

Lately, I've been trying to pay better attention to what settings I sleep better in, as well as certain things I do throughout the day or at night that might also effect the quality of sleep I get.  I've come to a few conclusions!
First of all, I always sleep better on the days that I get a good workout in.  I might've already touched on this, but ever since I've actually been paying attention to it, it has become extremely obvious to me that this is the case!  If I happen to miss a day of working out, it usually doesn't effect me a whole lot, but if I go more than 2 days without working out I can usually tell that I might not sleep as well, or I might wake up more frequently.  I think this is because of how the body and mind seem to rejuvenate or refresh while one sleeps, which we have discussed thoroughly in class, but I also think part of the reason might be because of my mindset about it.  I already think that I sleep better when I workout, so when I'm getting into bed and my muscles are already sore I immediately tell myself (sometimes a little excitedly) that I'm about to get a a great night of sleep that night. 
Second, I think I've realized that I don't like to sleep in the open.  I've always known this because I hate sleeping without any covers on, but I think it extends beyond that a little bit.  If I'm sleeping in a bigger room or a bigger area, I realize I don't feel as comfortable or relaxed as I do if I'm in a smaller space.  So, for example, I'm in a room in Davis, and they're fairly smaller than other rooms.  My room at my parents' house is bigger than this room, but I've noticed I feel almost more secure in a smaller room than in a larger one.  And interestingly enough, because of this I've actually started to sleep better in my smaller dorm room than in my larger bedroom when I go to my parents' house, and that makes me just a tad bit upset!  Hopefully I'll figure out a way to adjust a little better.
I've also decided to start tracking my sleep a little better.  I have a FitBit, which can track sleep if it's worn at night, and I'm going to start doing that more often to get a better feel of how I actually sleep at night.  We'll see what happens!
