Teenagers and Sleep

Information and tips

There have been many students arriving at school very tired and bleary eyed. I thought I would write a little about teenagers and sleep. Teenagers sleep patterns change dramatically during adolescence.

What is unique about teenagers’ sleep?
Teenagers' sleep tends to be less regular than the sleep of adults and young children. This means that the times when you go to bed on the weekend are not at all the same as on school nights. On weekends, you may go to bed much later. You may also wake up much later on the weekends. Late bedtimes on school nights makes it hard to get enough sleep. This is because you need to wake up early for school. You should aim for at least 8 hours of sleep on school nights.

What makes teenagers’ sleep less regular?
Teenagers’ biology works to make them go to bed later. Individual lifestyles play a part in this too. As you grow, you can stay up longer. Your 24-hour body clock can also move later, delaying the time that you feel sleepy at night and awaken in the morning. Up to a point these are natural changes. However there are other things that can also push the time you go to bed to later hours than desirable or make sense in terms of getting ready for the next day. These include using technology in the hour before going to bed (e.g. mobile phone, computer), and working too late (e.g. excessive homework, part-time evening job). On weekends, staying up too late and sleeping in too much can also upset your natural sleep wake rhythm, pushing your sleep patterns later.

How common are irregular sleep patterns in teenagers?
On weekends, about 90% of teenagers will go to bed later, and then sleep in. This can be OK if you do not change your weekend bedtimes by too much (no more than 2 hours). However about 40% of teenagers go to bed two or more hours later on weekends. This raises their chances of getting less than 8 hours sleep on school nights.

How do the sleep patterns of teenagers affect them?
While many teenagers cope with changing their hours of sleep some do not. Signs of not coping include if you are often late for school, feel sleepy during the day, feel moody or grumpy, and maybe not getting good grades at school.

What could you do to help cope?
There are ways to help your sleep to be more regular. At night, try to stop using technology earlier, dim the lights earlier, and start to relax earlier. Going to bed at a set time on school nights can help. On weekend mornings, try not to sleep in so long. When you do get out of bed on weekends, try to get a bit more outdoor light, and try to be a bit more active (e.g. get dressed earlier, have breakfast earlier, get moving earlier).
