Social jetlag (noun): Feeling tired because of changes in sleep schedule.

Consistent (adjective): Staying the same over time.

As we grow older, the amount of sleep we need changes. Teenagers, who are between 14 and 17 years old, need about 8 to 10 hours of sleep each night. This is similar to adults, who need 7 to 9 hours of sleep.

Why teens sleep differently

When we become teenagers, our sleep timing changes. We start to go to bed and wake up later. This happens to teenagers all around the world and even to other animals!

Early school = not enough sleep

Because school starts early, teenagers often have to wake up before they are ready. This means they don't get enough sleep during the week. On weekends, they can sleep in and try to catch up on the sleep they missed. This change in sleep schedule is called "social jetlag." It can make teenagers feel tired and can lead to problems like gaining weight and feeling sad.

How to feel more rested

To help with social jetlag, it's okay to sleep a little longer on weekends. But it's best to wake up within two hours of your usual time during the week. This helps you recover from lost sleep and keeps your sleep schedule more consistent.
