Many Americans are affected with this seasonal affective disorder, which is commonly known as SAD. According to the health specialists, some people become more depressed in the winter months, when the days are shorter and darker. Women are most probable victims of SAD when compared to men. People who suffer from this type of depression in the winter months lose their energy, suffer anxiety attacks, gain weight, sleep more and have reduced sex drive.  Suicides are also at the peak during this time of year.  However, light therapy seems to work magic to treat SAD. The depression is treated using light devices and there are no side effects. You can easily buy light devices at home at economical prices, after consulting your doctor.
