听力题 Do you have trouble sleeping at night? Then maybe this is for you. When you worry about meeting sleep and twisting around, trying to find a comfortable position. You''re probably only making matters worse. What happens is that your heart rate actually increases, making it more difficult to relax. You may also have some bad habits that contribute to the problem. Do you rest frequently during the day ? Do you get no exercise, or do you exercise late in the day? Do you sleep a lot or sleep late on weekends? Any of all these facts might be leading to your trouble in sleeping. What should you do then on those sleepless nights? Don''t bother with sleeping pills, they can actually cause even worse results later. The best thing to do is to drink milk or eat cheese. They will help you relax, and you''ll be on the way to get a good night''s sleep. Until tomorrow''s broadcast, this has been another series hint for good health by Doctor Handison.
