S.A.D stands for seasonal affective disorder and efffects and symptoms can include severe depression and anxiety. For those who suffer from S.A.D. they suffer from these symptoms only during certain seasons of the year. The most comon being summer or winter. Those with S.A.D. are fine the rest of the year.
Although the cause has yet to be determined, many doctors agree that it is the sun to blame. In the winter time there is less sunlight and this drop in daylight can mess with your bodies natural clock and make it harder to sleep and causing the amount of serotonin in your body to drop. As many of us know, serotonin is the chemical that is released when you are happy.
For those that suffer there are ways for relief. For winter S.A.D light therapy has been known to be effective. Doctors have also been known to prescribe melotonin and even anti-depression medication to help balance your body.
I never knew this exsisted but evey fall I go through a slight depression phase. I feel overwhelmed, exhausted and all I want to do is lay in bed in my pajamas. It's nice to know that there is a reason this seems to happen every year.
