Do you remember a time when you had no worries stopping you from getting a good night’s rest? Unfortunately, your happy childhood is probably a thing of the past. A recent survey has found that many people suffer from sleep problems. Some are unable to fall asleep, some wake up in the middle of the night, and others simply do not get enough sleep. One of the reasons why people fail to get a good night’s sleep is pressure from school or work. Noise pollution and light pollution in big cities may also contribute to sleep problems. In the short term, people with sleep problems often feel tired and have trouble concentrating. In the long term, they may be at increased risk of having a poor memory, being overweight and suffering a heart attack. Sleep problems are especially dangerous for teenagers. They are still growing, and night is the time when their bodies grow faster. Teenagers who do not sleep well may experience situations where body development slows down, and their health suffers. So, if you have trouble getting a good night’s sleep, it might be time to make some changes in your lifestyle. Task 1 Read the article and complete the following mind map.
