The new name isn’t quite as catchy as “SAD,” but it does describe the condition more precisely.
So let’s first review depression. Depression, or major depression, is a serious condition where someone loses their sense of life being enjoyable; this feeling of malaise affects every aspect of their day-to-day life, whether they’re working, studying, eating, or sleeping.
And when it’s dark out, the pineal gland releases the hormone melatonin, which is chemically related to serotonin.
Seasonal affective disorder (SAD) is a type of depression related to seasonal change, typically starting in the fall and winter months when there is less natural sunlight. Symptoms include hypersomnia, irritability, and carbohydrate craving. SAD is treated with light therapy, medication, and psychotherapy.
