Составьте двухминутную речь в пользу здорового сна

Healthy sleep is very important. Sometimes people underestimate it and create problems for themselves sleeping 4-5 hours a day. They wake up tired and spend all their day in a bad mood because they can't concentrate on their work. Sleep deprivation can also cause some serious health problems. That's why it's important to sleep 7-9 hours a day or even more for teenagers. Healthy sleep is a key to a great and efficient day.
