题目：Read the passage. Fill in the blanks with no more than three words. Try some light therapy! During the winter months, decreased levels of daylight can result in seasonal affective disorder, also described as SAD. Symptoms of SAD include a low mood, a lack of energy and a loss of interest in everyday activities. SAD sufferers might also find it hard to get up in the morning. One way of treating the SAD symptoms might be to try some light therapy in the form of SAD lamps. SAD lamps shine very bright, cool light. When this light hits the retina at the back of your eyes, it sends nerve signals to parts of your brain, affecting your chemical and hormone levels, and improving your mood. How do SAD lamps work? Sit with your eyes open about half a meter away from the SAD lamp for about half an hour to an hour a day. You can knit, work, watch television, etc. while you do so, but make sure that the light from the lamp falls on your face.
