It's important to think about the quality of your sleep. Sleep specialist Dr Rafael Pelayo said: "What you really want to do is wake up feeling refreshed — that's what it's about." He added: "If somebody tells me that they sleep many hours but they wake up tired, something is wrong. You shouldn't leave your favourite restaurant feeling hungry."

Use it only for sleep, sex and quiet activities like reading. Avoid bright lights, large meals, caffeine and alcohol before bed. Try things to help you relax, like a hot bath.

The quality of sleep is important
Most people need between seven and nine hours of sleep. However, the amount of sleep we need changes throughout our lives. Newborns need the most sleep, between 14 and 17 hours. As we get older, the amount of sleep we need decreases.
The quality of sleep is just as important as the quantity. Sleep specialist Dr. Rafael Pelayo says, "What you really want to do is wake up feeling refreshed — that's what it's about." If you're sleeping many hours but still waking up tired, something is wrong.
To improve the quality of your sleep, keep your bedroom dark, quiet, and at a comfortable temperature. Only use it for sleep, sex, and quiet activities like reading. Don't bring electronic screens like TVs or cell phones into the bedroom. Have a bedtime routine and avoid bright lights, large meals, caffeine, and alcohol before bed. Try relaxing activities like a hot bath, and make sure you're getting enough exercise during the day.
It's also important to listen to your body and pay attention to its sleep cues. There are definitely times when your body is telling you that you need more sleep. If you find yourself lying awake, get up and do something quiet until you feel sleepy.

If you're feeling tired during the day, you may want to consider taking a nap. Here are some tips on how to nap effectively:
- Find a good place to nap. It should be peaceful and quiet so that you will not be disturbed by others.
- Lie down or sit in a comfortable chair.
- Keep the room dark. A sleep mask may help.
- Listen to soft music or white noise.
- Try deep breathing or another relaxation technique, such as meditation, at the start of your nap.
- Keep your nap short. A brief 20-minute nap can help you feel more rested and alert when you wake up. Napping for longer than 30 minutes may leave you feeling groggy.
- Give yourself a few minutes to recover after your nap. Try a bit of stretching and walking around.
- Experiment with the timing, duration, and location of your nap. Consider keeping a nap diary where you can record your sleepiness or fatigue levels before and after your nap, as well as where, when, and how long you napped.
- If you're struggling to fall asleep, don't force it. Get up and do something quiet, like reading, until you feel sleepy.
