There are lots of things that you can do to give yourself the best possible chance of getting a good night's sleep catch up on your sleep now that you're back at school.

Read on to find out more.
Sleep is vital for humans - while we snooze our brain builds new connections, our body repairs itself and our energy is restored.
Studies have shown that sleeping helps both our physical and mental health, and increases our energy and ability to concentrate.
Many of us sacrifice sleep for lots of reasons - for example, to catch up on homework or to have more time to relax in the evening - but in the long run, this isn't good for our bodies.
A good night's sleep starts with how you behave in the day.
It's harder to get to sleep at night if you still have lots of energy stored up, so during the day, try going for walks or a run about if you can.
However tired you may feel, it's best not to nap during the day. Your body likes routine and taking naps in the day confuses it!
It's hard to sleep when your brain is whirring away - try to relax as much as you can at the end of the day.
That means no last-minute homework, running around too late, or drinks containing caffeine or lots of sugar.
If you're struggling to calm yourself at night, try taking a cool shower, meditating or reading. Even drinking a glass of water slowly or breathing deeply can help.
Stick to a routine
As hard as it is to do the same thing over and over, your body will thank you for it when it comes to sleeping.
Try to go to bed the same time each night, and wake up the same time each morning. It will get your body running like clockwork!
Many of us like to chill out by playing games, scrolling through social media or going on our phone.
These can be great ways to relax and have fun during the day, but in your last hour before bed, try to put them away if you can.
The bright lights from screens can keep us awake.
Cool as a cucumber
Finally, when you go to bed, make sure to keep the room nice and cool.
Maybe keep your window slightly open, if you're able to, so that fresh air can circulate around your room. You'll want to keep your curtains closed and turn all of the lights off.
A dark, cool room is the best way to send you soundly off to sleep.
