3. Sleep enough
Every living creature needs to sleep. Sleep is especially important for teenagers as it directly impacts mental and physical growth and development. The main benefit of sleep is the release of growth hormone which is needed by your body so that it can grow (toddlers can grow as much as 1.5cm overnight!).
As you grow up you will need to spend more time on homework and meeting with friends (online and offline). Some of the things we do as we get older can make it hard for us to sleep (e.g. watching TV close to bedtime). Remember that your parents are not punishing you if they send you to bed - they know that you need rest to grow taller and to be happy! If you do not get enough sleep it can be bad for health and can cause problems like not being able to pay attention in school or putting on extra weight.
Teenagers should be getting between 9- 11 hours per night. If you tend to sleep late on the weekend, that’s a message from your body to tell you that you need to sleep more on school nights.
