According to this article, 10 to 20 percent of the U.S. population suffer from seasonal depression, with women making up three-fourths of this percentage. Perhaps Dr. Holly has the cure for you, girls: GET SOME SUNSHINE!! I always feel so satisfied after a walk outside on a pleasant day. I grab my water bottle and some upbeat music and head right out the door. Oftentimes, I find myself smiling as I wander through the neighborhood because I just can't contain my happiness when I see the beauty of the world around me.
Once the weather is no longer cooperating, regardless of whether it is rainy, freezing, or just miserably hot, you'll be glad that you took advantage of those nice days while you had the chance. Rather than constantly working out in a stuffy indoor environment, take it outside where you've got an endless supply of fresh air. When you notice that the trees and flowers are growing, the trees are blossoming, and the birds are singing, go outside and join them for a little time in the sun. Chances are, you'll return home feeling happy AND healthy. :-)
