It is a common problem among all ages and it influences about 90 million American adults. People most at risk are males and those who are overweight, but snoring is a problem of both genders, although it is possible that women do not present this complaint as frequently as men.‎ ‎    Snoring is often the loud or harsh sound that can occur as you sleep. You snore when the flow of air makes the tissue in the back of your throat vibrate (颤动) as you breathe. The sound most often occurs as you breathe in air, and can come through the nose, mouth or both two organs. It can occur during any stage of sleep.‎ ‎    About half of people snore at some point in their lives. Snoring is more common among men, though many women snore. It appears to run in families and becomes more common as you get older. About 40percent of adult men and 24 percent of adult women are habitual snorers. Men become less likely to snore after the age of 70.‎ ‎    Sleeping on your back may make you more likely to snore. You may snore when your throat or tongue muscles are relaxed. And substances(物质) that can relax these muscles may cause you to snore. These include alcohol, muscle relaxants and other medicine.‎ ‎    Snoring can be a nuisance to your partner and anyone else nearby. You may even snore loudly enough to wake yourself up. Though, in many cases people do not realize that they snore. Snoring can also cause you to have a dry mouth when you wake up.‎ ‎    Light snoring may not disrupt your overall sleep quality. Heavy snoring may be connected with a risk factor in the heart disease, stroke and many other health problems. So never take it lightly.‎ ‎1. Why do some people snore during their sleep? A.

Here are some tips for beating shy feelings.‎ Start small with people you know. Practice social behaviors like eye contact, confident body language, introductions, small talk, asking questions, and invitations with the people you feel most comfortable around. Smile. Build your confidence this way. 1 .‎ Think of some conversation starters. 2 . Think of conversation openers, like introducing yourself, giving a compliment, or asking a question.

Find group activities where you can be with people who share your interests. Give yourself a chance to practice socializing (社交) with these new people, and get to know them slowly. People who are shy often worry about failing or how others will think about them. So treat yourself like your own best friend. Encourage yourself instead of expecting to fail.‎ Most of all, be yourself. It’s OK to try out different conversational ways you see others use 5 . Being the real you and daring to let yourself be noticed are what attract friends.‎ A. It’s important to make friends.‎ B. Then try to do this with new friends, too.‎ C. Give yourself a chance to take part in activities.‎ D. Write down what you want to say beforehand.‎ E. Often, the hardest part of talking to someone new is getting started.‎ F.
