It has been determined that the effect of a hormone called Melatonin is important in Seasonal Depression. Melatonin hormone, a hormone produced by the pineal gland in the brain, increases in dark environments. In autumn and winter, the shortening of the days and the decrease in the amount of sunlight available cause this hormone to increase. An increase in the melatonin hormone can cause effects such as slowing down a person's physical movements, fatigue, drowsiness, etc.
It is also important that the serotonin hormone decreases inversely to the increase in the melatonin hormone. Serotonin is a chemical (neurotransmitter) substance that affects people's energy, joy and enthusiasm and is known to increase its production in the body with sunlight. For this reason, it is considered an important factor in the formation of seasonal depression in terms of reducing energy and enthusiasm.
