B. Write out the implied main idea of the following paragraph. 3. 'If you have trouble getting a good night's sleep, don't have an alcoholic drink
before bedtime. While alcohol can certainly knock you out, it also damages
the quality of sleep you'll get. "That's because it chemically interferes with
dreaming, an important part of restful sleep. Also, avoid beverages and foods
that contain caffeine, such as coffee, most teas, colas, and chocolate. "Caffeine
can stimulate you, making sleep difficult or impossible. A better before-bed
choice is milk, which contains a mild, sleep-inducing type of protein. 'Another
piece of good advice is to exercise during the day; this can leave you tuckered
out enough at night to fall promptly and soundly asleep. But do avoid exercise
right before bedtime, as its immediate effects are more stimulating than
relaxing. Last, try to get up at about the same time every day; this practice will
help your body establish a solid sleep and wake cycle. "Varying your hours too
much can confuse your body's "inner clock."
