Winter can be a challenging time for many people. In spite of the fact we may feel stuck inside and want to curl up in bed with the day closing early if it goes beyond this and starts to affect how you feel and think, then it is seasonal depression or more scientifically "Seasonal Affective Disorder (SAD)" that requires attention.
Seasonal Affective Disorder (SAD) is a type of depression that’s triggered by a change in seasons, usually when the Autumn season starts. The shorter days and lesser daylight may cause neurochemical changes in the brain that lead to depression symptoms. It is believed that melatonin, a sleep-related neuro-hormone, plays an important role in this condition. In response to darkness, the pineal gland in the brain produces melatonin. As a result, the circadian rhythm (24-hour internal clock) and sleep timing are maintained. Seasonal Depression may significantly affect mood due to changes in Melatonin levels.
