As opposed to winter, autumn or early spring, I feel forced to keep all of my windows and blinds/curtains shut during the day to avoid the from place heating up too much. I have almost no daylight at all during the summer months, and am only able to open my windows once the sun goes down. During winter and early spring, I can keep my windows open all day. Ironically the season with the most daylight hours becomes the season with the least daylight to me. I not only obverse this behavior in myself, but in many other households as well.
I personally hate summer with a passion to begin with, and this only adds to my dislike for the season. The heat and high humidity, the insects, the birds, the blindingly bright sunlight, the increased electricity bill due to AC use. And on top the inability to do anything about it all. People with allergies suffer even more.
During the winter you can simply heat your house and wear warm clothing. If I want to cool down, I simply open a window. But during summer? All you can do is suffer. It is much more energy efficient to heat a space then it is to cool it. It also takes exponentially more effort to cool something then to heat it. Even from a purely logical point of view this season sucks. Even if you have an air-conditioned home, you are still powerless once you step outside.
I like to wear formal clothing, and my sensitivity to warm weather prevents me to wearing what I enjoy without suffering for it. There is really nothing about the summer that I like.
