Insomnia, the inability to fall or stay asleep, is a common problem that affects a significant number of pregnant women. According to research, up to 38% of pregnant females experience sleep disturbances during pregnancy. This lack of quality sleep can have a profound impact on a woman’s physical and emotional well-being, leaving her feeling exhausted and potentially increasing the risk of complications during pregnancy and childbirth. Insufficient sleep during pregnancy has been linked to an increased risk of gestational diabetes, preeclampsia, and prolonged labour. This article will explore the reasons behind pregnancy insomnia, its effects, and effective strategies to help you get the rest you need during this crucial time.
What is insomnia?
Insomnia is a sleep disorder characterised by difficulty falling asleep, staying asleep, or waking up too early and being unable to fall back asleep. It can be classified as acute (short-term) or chronic (lasting more than three months). Insomnia can manifest in different ways, such as:
- Sleep-onset insomnia: In this type of insomnia, one has trouble falling asleep at the beginning of the night and often lies awake for hours before drifting off.
- Sleep maintenance insomnia: This involves waking up multiple times and struggling to fall back asleep, leading to fragmented and non-restorative sleep.
- Terminal insomnia: This type of insomnia occurs when you wake up much earlier than desired, usually between 3 am and 5 am, and cannot go back to sleep.
While occasional sleeplessness is common and usually not a cause for concern, chronic insomnia can significantly impact a person’s quality of life and overall well-being, leading to daytime fatigue, cognitive impairment, and increased risk of accidents and injuries.
Why you can’t sleep: understanding the causes of pregnancy insomnia
During pregnancy, a woman’s body undergoes numerous hormonal and physical changes that can disrupt sleep patterns. These changes can contribute to the development or exacerbation of insomnia.
Hormonal changes: Hormonal fluctuations play a significant role in sleep disturbances during pregnancy. As progesterone and estrogen levels rise, they can impact the sleep-wake cycle and make it more difficult to fall and stay asleep. Progesterone has a sedative-like effect that can initially promote drowsiness but can also lead to fragmented sleep as levels continue to increase.
Physical discomforts: Pregnancy often comes with many physical discomforts that can interfere with sleep quality. Back pain, leg cramps, heartburn, and the need to frequently urinate due to pressure on the bladder can all contribute to difficulty falling and staying asleep. As the pregnancy progresses and the baby grows, the added weight and discomfort can further exacerbate insomnia.
Psychological factors: The emotional and psychological changes that accompany pregnancy can also cause sleep disturbances. Pre-sleep emotional thoughts about childbirth, the transition to parenthood, and concerns about the baby’s health can keep expectant mothers awake at night. Additionally, the excitement and anticipation of the baby’s arrival can make it challenging to wind down and relax before bedtime.
Sleep disorders: Some women may experience worsening of pre-existing sleep disorders like sleep apnoea due to weight gain and hormonal changes during pregnancy. Sleep apnoea, characterised by repeated episodes of breathing cessation during sleep, can lead to frequent awakenings, poor sleep quality, and excessive daytime sleepiness.
In addition to the factors mentioned above, certain lifestyle habits and environmental factors can also contribute to insomnia during pregnancy. Consuming coffee close to bedtime, engaging in stimulating activities before sleep, and exposure to blue light from electronic devices can all disrupt the body’s natural sleep-wake cycle. Furthermore, environmental factors like noise, light, and uncomfortable temperatures can make falling and staying asleep harder.
What to do: effective strategies for better sleep during pregnancy
While insomnia during pregnancy can be frustrating and exhausting, there are various strategies you can implement to improve your sleep quality. These strategies can be divided into several categories, including creating a relaxing bedtime routine, optimising your sleep environment, addressing physical discomforts, promoting relaxation and sleep onset, and maintaining healthy daytime habits.
Creating a relaxing bedtime routine
Establishing a consistent sleep schedule and engaging in calming activities before bedtime signal your body that it’s time to wind down and prepare for sleep.
- Read a book or listen to soothing music, as it reduces stress and facilitates better sleep.
- Take a warm bath or shower, as it promotes relaxation.
- Avoid activities like watching TV or using electronic devices shortly before bed, as they can disrupt your sleep cycle.
Optimising your sleep environment
Creating a sleep-conducive environment can significantly improve your chances of getting a good night’s rest. Here are some tips to optimise your sleeping space:
- Maintain a room temperature between 20°C and 25°C, as a warmer environment can disrupt sleep.
- Use blackout curtains or an eye mask to ensure complete darkness, as light exposure can suppress melatonin production and interfere with sleep.
- Use earplugs or white noise to minimise disruptions from external noises like traffic, neighbours, or snoring partners.
- A comfortable mattress and pillows that provide proper spinal alignment and support can promote better sleep.
Addressing physical discomforts
Pregnancy often comes with a host of physical discomforts that can interfere with sleep. To alleviate these issues, consider the following:
- Use pregnancy pillows to support your back, belly, and legs; they help relieve pressure and discomfort.
- Consult your healthcare provider about safe antacids or dietary modifications to reduce heartburn and indigestion.
- Drinking plenty of water and avoiding caffeine prevents leg cramps and frequent urination at night.
Promoting relaxation and sleep onset
Engaging in relaxation techniques calms your mind and body, preparing you for a more restful sleep. Consider practising the following:
- Deep breathing exercises can help to reduce stress and anxiety, promoting a sense of calm before bedtime.
- Progressive muscle relaxation, which involves systematically relaxing different muscle groups, releases physical and mental tension.
- Mindfulness meditation helps to quiet the mind and promotes better sleep.
- Practising gentle yoga poses and stretches releases physical tension and promotes relaxation.
Healthy daytime habits for better sleep
Healthy habits during the day can significantly impact your sleep quality at night. Here are some tips to consider:
- Regular moderate exercise, such as walking or prenatal yoga, promotes better sleep by reducing stress and fatigue. However, avoid intense workouts close to bedtime, as they can be stimulating and make it harder to fall asleep.
- Follow a balanced diet rich in tryptophan, magnesium and calcium, as these nutrients promote better sleep.
- Exposure to natural light for at least 30 minutes daily helps to regulate the circadian rhythm and improve the sleep-wake cycle.
- Avoid long daytime naps as they make it harder to fall asleep at night.
Safety and when to seek professional help
While over-the-counter sleep aids and herbal remedies may seem tempting when dealing with insomnia during pregnancy, it’s crucial to exercise caution and consult with your healthcare provider before using any medication or supplement. Many over-the-counter sleep aids and herbal remedies have not been extensively studied for safety during pregnancy and may pose risks to you and your developing baby.
If your insomnia persists for more than a few weeks, significantly impacts your daytime functioning, or is accompanied by symptoms of anxiety, depression, or other mental health concerns, it’s essential to seek professional help. Your healthcare provider can help you to optimise your sleep environment, establish a consistent sleep routine, and implement other sleep-promoting habits. He may recommend cognitive behavioural therapy (CBTi) and safe medication options for managing severe insomnia during pregnancy. However, medications are reserved for cases where non-pharmacological interventions have been ineffective, and the benefits of treatment outweigh the potential risks.
