( ВЫПИСАТЬ ГЛАГОЛЫ С ТЕКСТА)
Sleep is food for the brain (M03r). During sleep, important body functions and brain activity happens. Sleeping little can be harmful. You can look bad, feel bad, and you work poorly. If you don't sleep enough, you may find it difficult to get along with your family and friends and get bad marks at school. Remember: a brain that is hungry for sleep will get it, even when you don't expect it. When you do not get enough sleep, you are more likely to have an accident or illness.
teen = teenager
FACTS:
• Sleep is important to your well-being, as the air you breathe, the water you drink and the food you eat. It can even help you to manage the stress of being a teen.
• Teens need about 9 V4 hours of sleep each night to function best (for some, 8 V2 hours is enough). Most teens do not get enough sleep - one study found that only 15% reported sleeping 8 V2 hours on weekdays.
• Teens often have irregular sleep patterns - they typically stay up late and sleep in late on the weekends, which can affect their biological clocks and hurt the quality of their sleep.
CONSEQUENCES:
Not getting enough sleep or having sleep difficulties can:
• limit your ability to learn, listen, concentrate and solve problems. You may even forget important information like names, numbers, your homework or a date with a special person in your life;
• add to skin problems;
• lead to bad behaviour such as shouting at your friends or being impolite to your teachers or family members;
• make you eat too much or eat unhealthy foods like sweets and fried foods that lead to weight gain.
SOLUTIONS:
• Make sleep a priority. Decide what you need to change to get enough sleep to stay healthy and happy.
• Make your room very comfortable. Keep it cool, quiet and dark. If you need to, get dark curtains. Let in bright light in the morning to tell your body to wake up.
• Having caffeine close to bedtime can hurt your sleep, so avoid coffee, tea, coca cola and chocolate late in the day so you can get to sleep at night.
• Choose a bed and wake-time and stick to it, coming as close as you can on the weekends. A good sleep schedule will help you feel less tired.
• Don't eat, drink, or exercise within a few hours of your bedtime. Don't leave your homework for the last minute. Try to avoid the TV, computer and telephone one hour before you go to bed. Have quiet, calm activities, and you'll fall asleep much more easily!
• If you do the same things every night before you go to sleep, you teach your body the signals that it's time for bed. Try taking a bath or shower (this will leave you extra time in the morning), or reading a book.
