Two hours later I was still awake. I didn't feel sleepy so I got up, had another energy drink and continued watching TV. My parents were already in bed. I didn't fall asleep until 2 am! I don't want to stay up late, I just can't go to sleep. What's the matter with me? Cameron, 15 Dear Cameron Teenagers need more sleep than adults (nine hours per night, one more than adults) but less than children (twelve hours). Scientists think that teenagers are getting less sleep than before. Energy drinks can be part of the problem. They contain lots of sugar and calories, which give you energy. Did you know that one small can contains about 110 calories? That's equal to eating two large apples or a large banana. One small can contains nearly all of the sugar (nearly seven small spoons - 27 grams) you should eat in a whole day (32g)! It's less than a can of cola, but compares badly with the 12g in a banana and 10g per apple. This of course is bad for your weight and your teeth! Energy drinks are also often full of caffeine. You find caffeine in tea and coffee and it makes you feel more awake. It can also make you feel nervous, give you stomach aches and headaches, reduce your feelings of sleepiness and can even cause problems with your heart. So my advice is not to stay up late until you feel sleepy, but go to bed early. Reduce the number of energy drinks you have, or why not give them up completely? This will help your teeth and your weight as well, if that's a problem for you. Definitely don't have any after lunchtime, because the caffeine takes several hours to leave your body. Polly​
