Weather...

Ever been cranky when it was just too hot? Have you ever been gloomy or depressed when its cold or rainy? Can the weather affect our mood? This has always been an intriguing subject to me and others. It has even been studied by scientists and sociologists.
Like when the days are extremely hot, and you feel irritated or moody for no apparent reason. And what about when it is cold or rainy and gloomy and you feel sad, melancholy, even depressed, but you can't quite put your finger on it. Is there any evidence to substantiate these seemingly bizarre occurrences?
There are studies that link weather with long periods of high temperatures to increase in crime. It is believed that people get irritable and hostile when it is extremely hot. Several law enforcement agencies have statistics that shows the correlation of the two. Think about how you felt if ever you had experienced a heat wave. Made you how hot, irritable, frustrated, or maybe even angry.
In conclusion, there is some evidence that says that the weather can affect our mood. But not documented, I believe we can judge for ourselves, as well. If you have ever been happy and energetic on a bright sunny day, or sad and depressed or lack of energy on winter days or rainy days, or if you have been irritable on an extremely hot day, you have proven that, the weather does have some physical, however minimal, or psychological affect on our mood.
