After a busy day of work and play, the body needs to rest. Sleep is necessary for good health. During this time, the body recovers from the activities of the previous day. The rest that you get while sleeping enables your body to prepare itself for the next day.

　　There are four levels of sleep, each being a little deeper than the one before. As you sleep, your muscles relax little by little. Your heart beats more slowly, and your brain slows down. After you reach the fourth level, your body shifts back and forth from one level of sleep to the other.

　　Although your mind slows down, from time to time you will dream. Scientists who study sleep state that when dreaming occurs, your eyeballs begin to move more quickly (Although your eyelids are closed). This stage of sleep is called REM, which stands for rapid eye movement.

　　If you have trouble falling asleep, some people recommend breathing very deeply. Other people believe that drinking warm milk will help make you drowsy. There is also an old suggestion the counting sheep will put you to sleep!

Having one of those days – or weeks – when everything seems to annoy you? Even if you do nothing about it, your bad mood will probably go away after some time. But with a little effort, you can forget it much faster – often within a day or two.

◇Walk it off

Exercise is the most popular bad-mood buster. A person who’s in a bad mood has low energy and high tension. Taking a fast ten-minute walk, or doing some quick exercises can do wonders towards changing that bad mood.

◇Tune it out

Listening to your favorite music for a while can also make tension go away quickly, because music starts associations with past positive experiences we’ve had.

◇Give yourself a pep talk

Stop and listen to what’s on your mind. Bad moods are often started by too many negative thoughts. Write them all down on paper, the pessimistic messages you’ve been giving yourself and then give optimistic answers. ( “I still don’t have a job.” Vs “I have two interviews next week.”)

◇Reduce your stress

Relaxation techniques are wonderful mood-lifters. These include deep breathing, stretching and visualizing, all of which sound complicated but aren’t. One easy way to visualize: close your eyes and picture a favorite place, such as the beach. Another simple way to be against distress is to make a to-do list. One reason for being in a bad mood is feeling you have no options. By taking control over certain areas, you realize you’re not helpless. You can make changes in your mood and life.

◇Avoid things that won’t improve your mood.

TV may not help much: You need to increase your energy level and stimulate（刺激） your mind – something that the TV show “Neighbors” won’t do. And before you reach for that piece of cake and coffee, think about how mood and food are linked. Sugar and caffeine contribute to depressed moods. A better choice? Research shows that carbohydrates, such as potatoes and pasta（面食）,produce a calming effect in people who have a desire for them.

A．Energy Level and Stress B．How to Beat a Bad Mood

Scientists are making new studies of color and its effects on our health. They have known for a long time that the color of a room or the color of the light in it can affect our feelings and emotions. Many prisons and hospitals have at least one room that is painted pink. Officials have found that light and color can produce physical changes in our bodies.

Professor Falfan worked with a group of 9 disabled children at school in Albert. Two of the children were blind. The other seven had normal sight. The scientists changed the color of the school room, then looked for changes in blood pressure, heart beat and breathing rate. The effects of color changes were the same for the blind children as for those with normal sight. Their blood pressure dropped from about 120 to 100. Similar changes were reported in heart-beat and the breathing. The children also were calmer and less excited. Then the colors of the room were returned to orange and white. Blood pressure, heart-beat and breathing rate went up and the children became excited again.

Professor Falfan said different colors produce different levels of light energy. He said the differences seem to affect chemicals in the brain that carry messages from nerve to nerve and from nerve to muscle.

A．blind people can be affected by colors, too

C．the chemicals in the brain change with feelings and emotions

D．if one’s blood pressure drops, his breathing will get slower and slower

Teenagers who do not get enough of the nutrients commonly found in fruits and fish are easier to have bad lungs, coughing and wheezing （喘息）．Teens who eat the least of fruit and especially vitamin C have weaker lungs compared to the others．

Teens who take in less vitamin E, found in vegetable oil and nuts, are more likely to have asthma（哮喘）, Jane Bums at the Harvard School of Public Health found.

Based on these findings．Bums said that current recommended dose（一剂）of vitamin C, 85 mg a day, may not be enough for teens to have healthy lungs．Teens who eat less fruit and don't take in enough fatty acids （脂肪酸） are more likely to have asthma and the signs of breathing difficulty．

Proper amounts of fatty acids are protective, Bums said, though fish, the best source of fatty acids, is particularly unpopular with teenagers．Fatty acids are also found in some nuts as well as some green vegetables'．Smokers who avoid vitamin C will increase their chances of coughing, wheezing and developing phlegm（痰）．

More than 80 percent of teens are getting their recommended doses of vitamin C - mainly from fruit drinks．"I wouldn't approve of drinking them, but at least they're getting their vitamin C from somewhere," Burns said．

Burns added that there are several different ways to get the necessary nutrients．"I think vitamin supplements are fine．I think adding vitamin D to orange juice is fine．But I do think there are added benefits that we don't fully understand of eating whole foods like fruits and vegetables and fish," she said．The researchers did not account for poverty and other factors that often distinguish less-healthy eaters and may explain their findings．
