Sleeping may seem like a period of inactivity for your body and mind. But sleep is a dynamic state where your brain and body are busy with repair and regeneration – making sleep hygiene vital for your health.
 
Sleep hygiene is a set of good habits that help enhance sleep duration and quality, with excellent benefits for the brain and body. It enables you to fall asleep quickly and sleep well.
 
With enough good quality rest, you can wake up feeling refreshed, energised and alert, enabling you to be at your best during the day.

Studies suggest that sleep can help boost your immunity, contribute to longevity, and enrich your overall quality of life.
 
In young children and adolescents, sleep is crucial for growth. In deep sleep, the body also increases the production of proteins needed for cell growth and repair. Sleep also aids the nervous system functions, affecting thinking, memory and performance. In addition, it helps maintain a robust immune system to protect you from infections.
 
Getting a good night's rest – or at least #OneMoreHour of sleep – delivers many health benefits. Here are 10 ways to develop sleep hygiene practices to improve sleep health.

1. Develop a consistent sleep schedule

Get up and go to sleep at the same time, even on weekends and holidays. This helps your body's circadian rhythm determine your sleep and wakefulness schedule.

2. Avoid napping during the day

Napping provides positive benefits such as improved mood and energy levels, but the American Sleep Association states that naps can "decrease the sleep debt necessary for easy sleep onset."

3. Exercise regularly

Working out during the day can help you fall asleep more easily at night. But avoid exercising too close to bedtime. It can delay the onset of sleep due to a rush of endorphins in the body.

4. Limit caffeine intake

Too much caffeine, which can come from sodas, certain teas, and coffee, can disrupt your body's internal clock and keep you awake at night. So, avoid caffeine late afternoon and evening, especially if you're sensitive to even small amounts.

5. Avoid oversized meals before bedtime

Give your body time to digest a heavy meal to avoid disrupting your body's circadian rhythm. Limit fluid intake, too, so you don't keep waking up to go to the bathroom, which can make it difficult to go back to sleep.

6. Remove electronic devices from the bedroom

Watching shows, reading in bed, or working in your bedroom trains your brain to associate it with work and play instead of rest. Blue light from screens can also stimulate your brain and keep you wide awake.

7. Make your bedroom a relaxing and quiet place

Dim your lights to signal your body it's time to sleep. Keeping your bedroom dark, quiet and cool helps promote a good night's rest.

8. Establish a calming routine before bedtime

Soothing night-time routines – such as drinking caffeine-free herbal teas like chamomile or lavender, taking a warm bath, and meditating – can help you relax and unwind after a long day.

9. Clear your mind before bed

A 2018 study published in The Journal of Experimental Psychology: General found that participants who wrote down a detailed to-do list at bedtime fell asleep faster than those who journaled about completed tasks. So, if your mind is preoccupied with the things you still need to do, write them down. It may help make you feel more prepared for the next day.

10. Don't lie in bed when you can't sleep

Lying in bed can make you associate bed with wakefulness when you have insomnia or anxiety. Do something soothing like reading in another room for a few minutes until you feel sleepy. Then go to bed and try again.
 
This is one way to strengthen the bed and bedroom as cues for sleep – behavioural treatment for insomnia pioneered by clinical and research psychologist Richard R. Bootzin. If you have difficulty falling asleep, this can help establish a more consistent sleep-wake schedule.

Your sleep hygiene is vital to your sleep health, which is affected by the amount and quality of your sleep. Guidelines also show the amount of sleep necessary changes as you age.
 
Sleep experts worldwide recommend a range of seven to nine hours for adults, while children and adolescents require more to help them grow. (It is best to discuss your child's sleep with the paediatrician.)
 
Sleep quality and timing are equally important in delivering the necessary benefits for optimal health.
 
If you have a sleep disorder, your sleep hygiene may look different, so it is best to consult with your medical health practitioner.
