Seasonal affective disorder (मौसम की वजह से होने वाली बिमारी) is a mood disorder subset in which people who typically have normal mental health throughout most of the year exhibit depressive symptoms at the same time each year. It is commonly, but not always, associated with the reductions or increases in total daily sunlight hours that occur during the summer or winter. Common symptoms include sleeping too much, having little to no energy, and overeating. The condition in the summer can include heightened anxiety. In the United States, the percentage of the population affected by SAD ranges from 1.4% of the population in Florida to 9.9% in Alaska. SAD was formally described and named in 1984, by Norman E. Rosenthal and colleagues at the National Institute of Mental Health.
Seasonal affective disorder Meaning
Seasonal Affective Disorder (SAD) is a type of depression that occurs at a specific time of year, usually during the fall and winter months when there is less sunlight. It is sometimes referred to as “winter depression” or “winter blues.” SAD is believed to be related to changes in light exposure, which can affect the body’s internal clock (circadian rhythms) and lead to disruptions in the production of certain neurotransmitters, such as serotonin and melatonin.
