Jenna Levesque ATOC 1070 February 27, 2007 Seasonal Affective Disorder Every 365 days, the Earth, tilted on its axis, makes a complete revolution around the sun allowing for the changing of seasons throughout the year in each geographic location. The angle at which the sunlight hits the earth changes around the rotation and making the winter season occur when the sunlight is least direct. In the winter months, daylight decreases and the weather chills from the less direct sunlight. Not only does the lessened sunlight shorten the days and provide less heat, but its also is the main cause for Seasonal Affective Disorder (SAD). SAD is classified as a “winter depression” that is most prevalent in the Northern Hemisphere through the months of December, January, and February. Cases of SAD increase with altitude, where the days are shorter and winter months last longer. The amplified incidence in certain locations is related to their respective geographic placement on the globe. Because of the tilt of the earth, the winter months in the Northern Hemisphere are much more intense. Likewise, incidents increasing further from the equator can also be explained by the harsher winters and reduced exposure to sunlight characteristic of higher latitudes. This severe form of “winter blues” is estimated to affect half a million people
