                                                           Autumn blues? Let the sunshine in.

     Falling leaves, withering flowers, cold winds, faint sunshine. 1_____ Spirits can be low.

     People who suffer from "the autumn blues" often are extremely exhausted, lack energy, need more sleep,

feel increased appetite and gain weight.

     "The exact cause of this condition, often called seasonal depression or seasonal affective disorder (SAD),

is not known yet," says Chen Jue, associate professor at Shanghai Mental Health Center. "But recent studies

availability of sunlight."

     One theory is that with decreased exposure to sunlight, the biological clock that regulates mood, sleep,

and hormones is delayed, running more slowly in winter. 2_____. Another theory is that brain chemicals that

transmit information between nerves may be altered (改变) in individuals with SAD. It is believed that exposure

to light can correct these imbalances.
