Why Sleep Is Harder During Pregnancy
Sleep disruption during pregnancy is extremely common and affects the majority of pregnant women at some point — particularly in the first and third trimesters. The causes are varied and often compound each other: physical discomfort, hormonal changes, frequent urination, heartburn, restless legs, anxiety about the birth, and an increasingly difficult time finding a comfortable sleeping position.
Good sleep during pregnancy is not just important for the mother — it directly affects foetal development, immune function, and preparation for labour. Finding safe, natural ways to improve sleep quality is one of the most important things a pregnant woman can do for herself and her baby.
Sleep Problems by Trimester
| Trimester | Common Sleep Problems | Main Causes |
|---|---|---|
| First trimester | Fatigue, frequent urination, nausea, vivid dreams | Rising progesterone, hCG hormones |
| Second trimester | Restless legs, leg cramps, heartburn | Growing uterus, iron deficiency, acid reflux |
| Third trimester | Discomfort, frequent waking, anxiety, back pain | Baby size, pressure on bladder, pre-birth anxiety |
Evidence-Based Sleep Tips for Pregnancy
Sleep on Your Left Side
Sleeping on the left side is the recommended position from the second trimester onwards. It improves blood flow to the placenta, reduces pressure on the liver, and decreases back pain. A full-length pregnancy pillow supports the bump, back, and knees simultaneously and makes left-side sleeping significantly more comfortable.
Keep the Room Cool and Dark
Pregnancy raises core body temperature, making an already warm room even more disruptive to sleep. Keep the bedroom at 17–19°C where possible. A silk sleep mask is a safe and comfortable way to block early morning light that causes premature waking — the Rested Dusk Silk Sleep Mask and Dawn Silk Sleep Mask are both 100% mulberry silk and hypoallergenic — gentle on sensitive pregnancy skin.
Use White Noise
White noise is completely safe during pregnancy and is particularly useful for light sleepers who are already sleeping more lightly due to hormonal changes. The Rested Sounds & Stories plays white noise, pink noise, and nature sounds continuously overnight — masking variable sounds that cause waking and creating a consistent sleep environment.
Establish a Wind-Down Routine
Anxiety about the birth, the baby, and life changes is one of the most common causes of sleep difficulty in the third trimester. A consistent wind-down routine that signals to the nervous system that it is time to rest is particularly valuable during pregnancy. A warm shower using the Rested Sleep Body Wash — formulated with calming lavender and botanicals — is safe during pregnancy and triggers the thermoregulation response that supports sleep onset.
Apply a Calming Sleep Balm
The Rested Sleep Balm is formulated with lavender essential oil and magnesium — both safe for use during pregnancy. Lavender supports the GABA calming pathway and reduces anxiety. Magnesium can also help with the leg cramps that are common in the second and third trimesters. Always check with your midwife or GP before introducing new topical products during pregnancy.
Manage Heartburn
Elevating the head of the bed by 15–20cm using a wedge pillow reduces acid reflux during sleep. Avoiding large meals within 2–3 hours of bed and staying upright for 30 minutes after eating also helps significantly.

Preparing for Baby's Sleep Before the Birth
Pregnancy is the ideal time to set up a sleep environment for your newborn. Research shows that introducing white noise before the birth — so the baby hears it in utero — may help them associate it with comfort even faster after birth. Setting up the Rested Sounds & Stories in the nursery before baby arrives means you are ready to use it from night one.
Frequently Asked Questions
Is white noise safe during pregnancy?
Yes. White noise is completely safe for pregnant women and is one of the most effective natural sleep aids available during pregnancy. The Rested Sounds & Stories plays white noise, pink noise, and nature sounds — all safe to use throughout pregnancy.
Can I use a silk sleep mask during pregnancy?
Yes. A silk sleep mask is completely safe during pregnancy and is particularly useful for blocking early morning light that causes premature waking. The Rested Dusk and Dawn Silk Sleep Masks are hypoallergenic and gentle on sensitive skin.
Is lavender safe during pregnancy?
Lavender in topical products and aromatherapy is generally considered safe during pregnancy in normal amounts. However, always check with your midwife or GP before introducing new topical products during pregnancy, particularly in the first trimester.
Why can't I sleep during pregnancy even when I'm exhausted?
Hormonal changes, physical discomfort, frequent urination, and anxiety all contribute. Even when physically exhausted, elevated cortisol and progesterone can make it difficult to settle. A consistent wind-down routine, cool dark room, and white noise address the environmental and behavioural factors that compound the hormonal ones.
What is the best sleeping position during pregnancy?
Left side sleeping from the second trimester onwards. This improves blood flow to the placenta and reduces pressure on the liver. A full-length pregnancy pillow makes this position significantly more comfortable.
