KK Women's and Children's Hospital (KKH) explains the importance of sleep during pregnancy, dangers of having a lack of it, and simple tips for good sleep.
1. Sleep: Guide
Sleep is an important restorative behaviour and plays an integral role in your health. To improve your sleep quality, it is important to understand how sleep helps to restore our health and energy.
Why do we sleep?
Sleep allows our brains to consolidate our learning and memory so we can perform tasks better the next day. When we have enough sleep, we are less likely to overeat and crave unhealthy food and make wiser food choices.
Symptoms of sleep deprivation
Health risks of poor sleep
There are many health risks associated with poor quality sleep for preconception women, pregnant and postpartum women.
Sleep in pregnancy
Sleep is important in pregnancy but sometimes changes to your body makes it difficult to fall asleep and get comfortable. Pregnant women are more prone to sleep disturbances and short sleep duration due to hormonal changes, physical discomfort, sleep disorders and anxiety associated with childbearing that they experience. Many women experience sleep disturbances especially in their second and third trimester.
Getting quality sleep during pregnancy is important for both mother and baby. Insufficient and poor quality sleep are associated with pregnancy complications like gestational diabetes, high blood pressure and early birth.

Changing your behaviour with good sleep hygiene
Sleep hygiene refers to healthy sleep habits or behaviours that you can adopt to improve your ability to fall asleep and remain asleep throughout the night. Changing your behaviour is crucial in achieving better quality sleep! There are some ways in which you achieve this.
1) Go to sleep and lie down on your bed ONLY when you are sleepy.
Avoid lying in bed and forcing yourself to sleep if you don’t feel sleepy.
The bed should only be used for sleep and intimacy.
This will help your brain to associate your bed for sleeping only, making it easier for you to fall asleep in the long run.
2) If you are not able to fall asleep after 20 minutes of lying in bed, GET UP and go to another room.
It is a common misconception that we should stay in bed and try to fall back to sleep when we have difficulty falling asleep.
Although it seems counter-intuitive, it is better to leave your room and do other activities such as reading, listening to soft music. Only come back to your bed when you are feeling sleep.
3) Set a regular sleep and wake time
This will help you strengthen your circadian clock which regulates your sleep and wake cycle.
Try to maintain a regular sleep and wake up time every day, including the weekends
4) Avoid napping too much in the day
Limit your napping to once a day for a short duration of 15 to 30 minutes.
It should be taken approximately 7 to 9 hours after waking up. It can be refreshing and not likely to disturb your nocturnal sleep.
5) Sleep in a cold, dark and quiet bedroom
6) Avoid caffeine, nicotine, alcohol before bed
Avoid big meals, smoking, alcohol, caffeine, heavy, spicy or sugary foods four to six hours before bedtime.
7) Minimise your pre-bedtime screen time
8) Exercise regularly
Especially if taken earlier in the day, exercise can help improve sleep quality, allowing you to fall asleep faster, and sleep more easily and soundly.
However, vigorous exercise in the late afternoons and evenings should be avoided as it can make falling asleep at night more difficult.
For more information on how to get started on exercising and what kind of exercises to do, check out our section on
9) Manage your stress
Stress can cause you feel anxious and your heart to beat faster, making it more difficult for you to fall asleep.
A way of managing your stress is to designate a worry time – a particular time period of the day set for thinking about things that worry you. This can help to reduce your worried thoughts when you are going to sleep at night.

10) Avoid supplements like melatonin
If you feel you that you require supplements or medications to help with sleep, discuss it with your doctor.
Products labelled as ‘natural’, such as melatonin, have the potential to interfere with your body’s normal processes, especially if you’re trying to conceive or in pregnancy.
Here are additional tips for getting yourself comfortable when sleeping during your pregnancy.
Relaxation techniques help to limit cognitive arousal and reduce muscular tension that might be making it difficult for you to fall asleep.
Relaxation techniques include mindfulness, meditation, guided imagery and breathing techniques. Here are some ideas on how you can practice these relaxation techniques!
