What is a seasonal affective disorder?

seasonal affective disorder (SAD) is a mood disorder that many feel in winter. It is characterized by seasonal depression, "blues", a desire to feel or withdraw and often with a desire for star meals. While the "Winter Blues" have long been recognized, seasonal affective disorder has been studied from the age of 80. Its mechanism is still not understood, but intuitively it seems that it is an evolutionary delay in the past of nearby nature. When the days shorten and the nights are long, they could expect our ancestors to limit their activities, retreat to a cozy shelter, and sleeping a large part of time, spending their awakening, perhaps repairing their hunting equipment and telling stories around the municipal fire pit.

Since our modern lifestyle does not mean space for the need for hibernation, people can find themselves stress to be forced to be forced into everyday activities when they want to tell only stories and sleep. A seasonal affective disorder is therefore a very real physiological phenomenon and one that can be treated. AssumptionIt is that shorter days and lack of daylight may cause melatonin overproduction, a hormone related to sleep that is formed in the wider gland; After melatonin overproduction, depression is often followed. The current treatment of seasonal affective disorders uses fully spectral light for several hours-dokonce only an hour-day, which suppresses melatonin secretion, thus increasing the mood of the sad upright.

If you usually go through a period of depression in winter, especially in January and February, which lack the holidays to get the mood, and do not suffer from depression at any other time of year, it is likely that you are hit by seasonal affective disorder. Some studies claim that up to thirty percent of adults in countries in their countries are affected by a seasonal affective disorder to some extent. Most seasonal affective disorders can find that simply walking out of the door for an hour a day gives them enoughdaylight to reduce symptoms. Others may have to try the therapy of inner light or even medicines. Perhaps it is unfortunate that we can no longer retreat to the cave to deal with a quality switching on and starch refreshments.
