Sleep, Rest and Recovery

Sleep is a superpower

When you climb into bed and close your eyes, it might feel like nothing is happening. But your body is actually doing some of its most important work while you sleep. Sleep is like a nightly repair shop and recharge station for your whole body and brain.

Sleep, rest, and recovery are not the opposite of being active and healthy. They are a key part of it. You cannot run, learn, and grow well without them.

What happens while you sleep

While you are sleeping, your body is busy:

• Repairing muscles. When you run and play, your muscles get tiny stresses. Sleep is when they get fixed and made stronger.
• Growing. Your body releases special growth signals during deep sleep. That is part of how you get taller!
• Refreshing your brain. Your brain sorts and stores what you learned during the day, which helps your memory.
• Recharging energy. You wake up with a fresh supply of energy for the new day.

So sleep is not wasted time at all. It is when a lot of the magic of growing up and getting stronger actually happens.

Why rest days matter too

Sleep is rest at night. But rest also matters in the daytime. Here is a surprising fact: you do not get stronger during exercise. You get stronger afterwards, while you rest!

When you exercise, you put a small, healthy stress on your muscles. Then, during rest and recovery, your body repairs them and builds them back a little stronger than before. This is why athletes take rest days and do not train hard every single day. Resting is part of training, not the opposite of it. Older athletes plan this carefully, as you can read in why sleep matters for athletes.

If you exercise hard all the time with no rest, your body cannot catch up. You may feel tired, sore, and grumpy, and you might even get hurt. So a good plan mixes active days with rest days.

How much sleep do you need?

Different ages need different amounts of sleep. Most primary-age children (around 6 to 12 years old) need about 9 to 11 hours of sleep each night. That is a lot more than grown-ups need!

When you get enough sleep, you feel:

• happier and calmer
• more energetic for play and sport
• better able to concentrate and learn

When you do not get enough sleep, you may feel grumpy, tired, forgetful, and find it harder to do your best. Good sleep even helps your mood, which connects to feeling good through movement too.

How to sleep well

Getting good sleep is a skill you can practise. Here are some friendly tips:

• Have a bedtime routine. Doing the same calm steps each night tells your brain it is time to wind down.
• Switch off screens about an hour before bed. Bright screens can trick your brain into thinking it is still daytime.
• Keep your room dark, quiet, and cool. This helps your body drift off.
• Go to bed at a similar time each night, even at weekends if you can.
• Be active in the daytime. Moving and playing helps you sleep better at night. Try to be active every day.

Activity: build your dream bedtime routine

Design your own calm bedtime routine with a grown-up. Pick four or five quiet steps to do in the same order each night, for example:

1. Have a warm bath or shower
2. Put on your pyjamas and brush your teeth
3. Switch off all screens
4. Read a story or look at a book in soft light
5. Lights out, snuggle down, and think of something happy

Write or draw your routine on a chart and put it near your bed. Follow it every night for one week. Notice whether you fall asleep more easily and feel more rested in the morning.

Remember: sleep and rest are not lazy. They are when your body grows, repairs, and gets ready to be amazing again tomorrow. Look after your sleep, and your sleep will look after you.
