Seasonal affective disorder (SAD) is a type of depression that sets in or starts in the winter months. Unlike other types of depression, it may improve as spring comes on. It is often a cyclical, recurring disorder--you'll feel depression every winter and begin to feel better each spring.
季節(jié)性情緒紊亂（seasonal affective disorder，SAD）指多發(fā)于冬季的一種抑郁癥，也稱“冬季抑郁癥”。與其它類型的抑郁癥不同的是，這種季節(jié)性抑郁癥會(huì)在春天到來(lái)時(shí)有所好轉(zhuǎn)。這是一種循環(huán)的、反復(fù)發(fā)生的情緒紊亂，每年冬天時(shí)覺(jué)得抑郁，春天到來(lái)時(shí)又好轉(zhuǎn)了。
A study by Alfred Lewy at the Oregon Health and Science University found that most of the symptoms of seasonal affective disorder are caused by body rhythms that are not in sync with the sun. Often the body gets out of sync with the sun because of winter's shortened days. The pineal gland, which regulates body rhythms, secretes a hormone called melatonin during the night. This can affect your sleep wake cycle and other rhythms. When it gets dark too early in the day, the pineal gland and the body's sleep wake cycle get out of sync.

Seasonal affective disorder is far more common in northern climates, where days can be very short in winter. SAD affects more women than men and is likelier to occur in people under age 40 than those older than that.
