Strange Sleep Patterns During Pregnancy: Causes & Tips

Sleep changes can be one of the very first things that women notice when they become pregnant. A woman who once had a good sleep routine may find herself confused by changes in her sleep patterns. While she had no trouble falling asleep before, when pregnant she may feel fatigued during the day or may not cope with sleeping through the night. Changes in sleep patterns may seem strange, but the truth is that it is a normal reaction of the body.

Why Do Sleep Patterns Change During Pregnancy?

There are many changes that occur during pregnancy, which can affect sleep behaviour. These changes can be attributed to hormonal fluctuations, physical discomfort, and emotional worries. According to Dr Mannan Gupta, sleep problems during pregnancy are normal and usually stem from these factors.

Hormones like progesterone facilitate the body's methods of relaxation, but increase drowsiness simultaneously. Moreover, physical discomfort and emotional experience can impair sleep quality.

What Are Common Sleep Changes in Pregnancy?

Women who are pregnant report experiencing similar alterations in their sleeping pattern. They include:

Sleeping longer: This is particularly seen in the early stages of pregnancy due to increased tiredness
Waking up multiple times: This is especially at night when sleep becomes lighter and is easily disturbed
Having difficulty falling asleep: Pregnant women might not be able to fall asleep as quickly as before
Having strange dreams: Dreams during pregnancy turn out to be more vivid

In general, these changes do not persist for a long period of time and differ considerably depending on the person.

“Changing sleep patterns are often the first gentle sign that a woman’s body is adjusting to the early stages of pregnancy”

Dr Mannan Gupta, Chairman & HOD- Obstetrics & Gynecology, Elantis Healthcare, New Delhi

Understanding Sleep Changes Across Trimesters

Sleep patterns evolve as pregnancy progresses through each of its stages. Each trimester is accompanied by particular sleep disturbances.

First Trimester: Extreme Sleepiness

In the first trimester, progesterone levels increase rapidly. The result is persistent sleepiness and the need for more hours of sleep.

Women tend to:

Be sleepy even when well rested
Frequently take multiple naps
Sleep poorly at night

Second Trimester: Get Good Rest

In the second trimester, women report less difficulty sleeping. At this stage, almost all women experience better functioning with fewer mood swings. However, some minor discomfort may still arise, interfering with sleep quality.

Third Trimester: Interrupted Sleep

In the last months of pregnancy, women may face considerable sleeping issues. The growing fetus and the following physiological changes lead to discomfort:

Frequent need to urinate
Back pain
Burps and heartburn
Cramps in the legs
Baby movements

What Other Factors Can Affect Sleep?

Besides the physical and hormonal changes, some other factors can affect sleep, such as:

Stress and anxiety: Worries about delivery or parenting may cause sleep disruption
Changes in body temperature: Pregnancy may make some women feel warmer than normal at night
Changes in breathing: Mild discomfort during breathing is experienced by some women

Practical Tips to Improve Sleep

There are ways to improve sleep even though changes in sleep patterns are often experienced by pregnant women.

Stick to a routine: Go to bed and wake up at the same time daily
Sleep on your left side: This position improves blood circulation to the baby
Use pillows for extra comfort: You can put pillows beneath your belly and between your legs for extra comfort and ease
Do not eat heavy meals: Refrain from eating heavy meals during bedtime to avoid heartburn during sleep
Limit caffeine intake: Ensure you do not take more than 2 cups of caffeine throughout the day, and try to avoid it in late evenings
Be active during the day: Gentle pregnancy-safe exercises can help you sleep better
Have a peaceful environment: Keep the room dark, comfortable, and quiet to provide a relaxing and soothing place to sleep well
Wear comfortable clothes: Since many pregnant women experience warmer temperatures at night, it is recommended to wear cool, light, and comfortable nightwear

When to Seek Medical Help

You should consult your doctor if you experience any of the following symptoms:

Severe insomnia lasting for a long time
Loud snoring or difficulty breathing
Continuous pain in your legs accompanied by swelling
Extreme fatigue affecting your daily life

Changes in sleep are a normal occurrence during pregnancy and indicate the body's attempt to support a new life. While these changes might be uncomfortable, you might be able to relieve them by following simple recommendations such as sticking to a schedule, sleeping in specific positions, and making some lifestyle changes.
