Physical changes during pregnancy

Increased hormone levels

During pregnancy, our bodies experience a surge in hormone levels. These hormonal changes can have a significant impact on our sleep patterns. One hormone that increases during pregnancy is progesterone. Progesterone has a sedative effect, making us feel more tired and sleepy. On the other hand, the increased levels of estrogen can cause discomfort and disrupt our sleep. Additionally, oxytocin, also known as the “love hormone,” increases during pregnancy and can affect our ability to fall asleep and stay asleep.

Weight gain and bodily changes

Another physical change during pregnancy is weight gain. As our bodies grow to accommodate the developing baby, the extra weight can cause discomfort and make it challenging to find a comfortable sleeping position. The increase in weight can also put pressure on our joints and lead to back pain. These physical changes can make it harder to get a good night’s sleep.

Increased blood volume and circulation

Pregnancy leads to an increase in blood volume to support the growing baby. This change can affect our sleep by causing frequent urination. As our blood volume increases, our kidneys have to work harder to filter our blood, which leads to increased urine production. The need to get up and use the bathroom frequently throughout the night can disrupt our sleep and make it harder to fall back asleep.

Frequent urination

As mentioned before, the increased blood volume and circulation during pregnancy can cause frequent urination. This issue can be particularly challenging during the later stages of pregnancy when the growing uterus presses against the bladder. The constant need to use the bathroom can disturb our sleep and make us feel more tired during the day.

Common sleep problems during pregnancy


Insomnia, the difficulty in falling asleep or staying asleep, is a common sleep problem during pregnancy. The combination of hormonal changes, physical discomfort, and heightened emotions can contribute to insomnia. It is essential to establish a bedtime routine and create a comfortable sleep environment to promote better sleep.

Nausea and vomiting

Many pregnant women experience nausea and vomiting, especially during the first trimester. These symptoms can worsen at night, making it difficult to sleep. Eating small, frequent meals, avoiding trigger smells, and drinking ginger or peppermint tea can help manage the nausea and vomiting and improve sleep quality.

Restless legs syndrome (RLS)

Restless legs syndrome is characterized by an uncontrollable urge to move the legs, often accompanied by uncomfortable sensations. Pregnancy can exacerbate RLS symptoms, making it harder to relax and fall asleep. Regular exercise, leg stretches, hot and cold therapy, massage, and leg elevation can provide relief from RLS symptoms and promote better sleep.

Snoring and sleep apnea

Snoring and sleep apnea can affect pregnant women due to weight gain and changes in hormonal levels. These sleep disorders can lead to disturbances in breathing and prevent restful sleep. Sleeping on the side, using nasal strips or a nasal dilator, maintaining a healthy weight, and seeking medical evaluation can help address snoring and sleep apnea during pregnancy.

Heartburn and acid reflux

Heartburn and acid reflux are common during pregnancy, particularly in the later stages. The growing uterus puts pressure on the stomach, causing stomach acid to flow back into the esophagus, leading to discomfort and sleep disturbances. Eating smaller meals, avoiding trigger foods, sleeping with an elevated upper body, and using antacids or other medications can alleviate heartburn and acid reflux symptoms.

Hormonal changes and sleep

Effects of progesterone

Progesterone, a hormone that increases during pregnancy, has a sedative effect, making us feel more tired. However, progesterone can also contribute to disrupted sleep and awakenings during the night due to its impact on breathing patterns. This hormonal change can make it harder to achieve restful sleep during pregnancy.

Role of estrogen

Estrogen, another hormone that increases during pregnancy, can cause discomfort and disrupt sleep. Estrogen can make our nasal passages more congested and lead to snoring and difficulty breathing during sleep. Additionally, estrogen can affect our mood and emotions, which can contribute to sleep disturbances.

Impact of oxytocin

Oxytocin, often referred to as the “love hormone,” increases during pregnancy. While oxytocin is essential for bonding with the baby and promoting relaxation, it can also interfere with sleep. The heightened levels of oxytocin can create feelings of restlessness and make it difficult to fall asleep and stay asleep throughout the night.

Melatonin and sleep patterns

Melatonin, a hormone that regulates sleep-wake cycles, plays a crucial role in our sleep patterns. During pregnancy, the levels of melatonin can fluctuate, leading to changes in our sleep patterns. The disruptions in melatonin production can contribute to insomnia and other sleep problems commonly experienced during pregnancy.

Body changes and sleep comfort

Growth of the uterus

As the pregnancy progresses, our uterus expands to accommodate the growing baby. The increased size of the uterus can put pressure on neighboring organs, such as the bladder and intestines. This pressure can lead to frequent urination and make it challenging to find a comfortable sleeping position.

Breast size and tenderness

During pregnancy, our breasts undergo significant changes in preparation for breastfeeding. The increased size and tenderness of the breasts can affect sleep comfort, making it more challenging to find a comfortable position. Using supportive bras and pillows can help alleviate discomfort and improve sleep quality.

Increased blood flow

The increased blood volume and circulation during pregnancy can also impact sleep comfort. The rise in blood flow can cause warmth and sweats, leading to discomfort during sleep. Keeping the bedroom cool and using breathable bedding can help regulate body temperature and improve sleep comfort.

Back pain and discomfort

As our bodies adjust to the growing baby, many pregnant women experience back pain and discomfort. The additional weight and changes in posture can strain the back muscles and spine, leading to sleep disturbances. Using pillows for support, practicing good posture, and engaging in exercises specifically targeting back pain can alleviate discomfort and promote better sleep.

Changes in lung capacity

During pregnancy, our lung capacity can be reduced due to the pressure exerted by the expanding uterus on the diaphragm. This change may cause shortness of breath and difficulty breathing while lying down, making it uncomfortable to sleep. Adjusting sleep positions to allow for better airflow and using extra pillows for support can help manage this issue and improve sleep quality.

Sleep hygiene tips for pregnant women

Establishing a bedtime routine

Establishing a consistent bedtime routine can signal to our bodies that it is time to relax and prepare for sleep. Engaging in calming activities such as reading, taking a warm bath, or practicing relaxation exercises can help promote better sleep during pregnancy.

Creating a comfortable sleep environment

Creating a comfortable sleep environment is crucial for getting quality sleep during pregnancy. Keep the bedroom cool, use comfortable and breathable bedding, and invest in a supportive mattress and pillows. Additionally, using blackout curtains or an eye mask can block out any unwanted light and promote a more restful sleep environment.

Maintaining a healthy diet and exercise

Maintaining a healthy diet and exercise routine during pregnancy can positively impact sleep. Eating a balance of nutritious foods, staying hydrated, and engaging in regular physical activity can help regulate our hormones and promote better sleep. However, it is important to avoid heavy meals and strenuous exercise close to bedtime to prevent sleep disturbances.

Managing stress and anxiety

Pregnancy can bring about a range of emotions, and stress and anxiety can interfere with sleep. Finding healthy ways to manage stress, such as practicing relaxation techniques or engaging in activities that bring joy, can help improve sleep quality. It may also be helpful to talk to a healthcare provider or therapist for additional support.

Using relaxation techniques

Relaxation techniques, such as deep breathing, meditation, and guided imagery, can be beneficial in promoting relaxation and better sleep during pregnancy. These techniques can help calm the mind and reduce anxiety, allowing us to unwind and prepare for a restful night’s sleep.

Dealing with insomnia during pregnancy

Avoiding caffeine and large meals

Caffeine and large meals can stimulate our bodies and make it harder to fall asleep. It is important to avoid consuming caffeine, such as coffee or tea, close to bedtime. Additionally, eating smaller, balanced meals earlier in the evening can prevent digestive discomfort and promote better sleep.

Managing nighttime bathroom trips

Frequent urination is a common issue during pregnancy, especially during the later stages. To minimize nighttime bathroom trips, it can be helpful to limit fluid intake in the evening and empty the bladder before going to bed. Additionally, placing a nightlight in the bathroom can help navigate during nighttime trips without fully waking up.

Using pillows for support

Using pillows for support can alleviate discomfort and help find a more comfortable sleeping position. Placing a pillow between the legs, under the belly, or behind the back can provide extra support and reduce strain on the body. Maternity pillows specifically designed for pregnant women are also available and can offer optimal support for better sleep.

Finding a comfortable sleeping position

Finding a comfortable sleeping position during pregnancy can be challenging, especially as the belly grows larger. Sleeping on the side, particularly the left side, is recommended as it improves circulation and allows for better oxygen flow to the baby. Placing a pillow between the knees can help maintain proper alignment and enhance comfort.

Practicing relaxation exercises

Engaging in relaxation exercises before bed can help calm the mind and promote better sleep. Deep breathing, progressive muscle relaxation, and gentle stretching can help relax the body and prepare for restful sleep. It may be beneficial to incorporate these exercises into the bedtime routine to signal to the body that it is time to unwind and sleep.

Managing nausea and vomiting at night

Eating small, frequent meals

Eating small, frequent meals throughout the day can help manage nausea and vomiting during pregnancy. Avoiding large meals and consuming foods that are easy to digest can minimize stomach discomfort and reduce the chances of experiencing nighttime symptoms. It is also helpful to have a small snack by the bedside for immediate relief in the morning.

Avoiding triggering smells

Certain smells can trigger nausea and vomiting during pregnancy. It is important to identify and avoid any scents or odors that may worsen symptoms, especially in the bedroom. Keeping the bedroom well-ventilated and free from strong odors can help prevent nighttime episodes of nausea and improve sleep quality.

Drinking ginger or peppermint tea

Ginger and peppermint are natural remedies known for their soothing properties and ability to alleviate nausea. Drinking ginger or peppermint tea before bed can help calm the stomach and reduce the likelihood of experiencing nighttime episodes of nausea. It is important to consult with a healthcare provider before incorporating any herbal remedies into the routine.

Using acupressure wristbands

Acupressure wristbands are knitted bands that apply pressure to specific points on the wrist, known as acupressure points. These bands are designed to relieve nausea and can be worn throughout the day and night. Utilizing acupressure wristbands while sleeping can provide continuous relief from nighttime nausea and vomiting.

Addressing restless legs syndrome (RLS)

Regular exercise and stretching

Regular exercise, particularly leg stretches and gentle movements, can help alleviate symptoms of restless legs syndrome. Engaging in physical activity earlier in the day can help reduce restlessness and promote better sleep at night. However, it is important to avoid intense exercise close to bedtime, as it can stimulate the body and make it harder to fall asleep.

Hot and cold therapy

Applying hot or cold therapy to the legs can provide relief from restless legs syndrome symptoms. Taking a warm bath or using a heating pad before bed can help relax the muscles and reduce the urge to move the legs. Alternatively, applying a cold compress or soaking the legs in cold water can have a soothing effect and alleviate discomfort.

Massage and leg elevation

Massaging the legs, particularly the calves and thighs, can help relax the muscles and relieve restless legs syndrome symptoms. Using gentle, circular motions and applying a soothing lotion can enhance the effects of the massage. Additionally, elevating the legs on a pillow or cushion can promote better blood flow and reduce the urge to move the legs.

Medication options

In severe cases, medication may be prescribed to manage restless legs syndrome symptoms during pregnancy. However, it is important to consult with a healthcare provider before taking any medication. They can provide guidance on the safety and appropriate use of medications to alleviate restless legs syndrome and improve sleep quality.

Dealing with snoring and sleep apnea

Sleeping on your side

Sleeping on the side, particularly the left side, is recommended during pregnancy to improve circulation and allow for better airflow. This sleeping position can help minimize snoring and reduce the risk of sleep apnea episodes. Using pillows to support the body and maintain the side-sleeping position can further enhance comfort and prevent the likelihood of rolling onto the back.

Using nasal strips or a nasal dilator

Nasal strips or a nasal dilator can be effective in reducing snoring and improving breathing during sleep. These products work by opening up the nasal passages, allowing for better airflow and reducing the vibration that causes snoring. Nasal strips can be applied externally, while a nasal dilator is inserted into the nostrils.

Maintaining a healthy weight

Maintaining a healthy weight during pregnancy can help reduce the likelihood of snoring and sleep apnea. Excess weight can contribute to airway obstruction and breathing difficulties during sleep. Following a balanced diet and engaging in regular physical activity as recommended by a healthcare provider can support overall weight management and improve sleep quality.

Seeking medical evaluation

If snoring or suspected sleep apnea persists or worsens during pregnancy, it is important to seek medical evaluation. A healthcare provider can assess the symptoms, determine the underlying cause, and recommend appropriate treatment options. They may refer you to a sleep specialist for further evaluation and management of sleep disorders during pregnancy.

Coping with heartburn and acid reflux

Eating smaller meals

Eating smaller, more frequent meals can help minimize heartburn and acid reflux symptoms during pregnancy. Consuming smaller portions reduces the amount of stomach acid that is produced, helping to prevent discomfort and reflux episodes. It is also advisable to eat meals at least two to three hours before bedtime to allow for proper digestion.

Avoiding trigger foods

Certain foods can trigger or worsen heartburn and acid reflux during pregnancy. It is important to identify and avoid these trigger foods to minimize symptoms. Common triggers include spicy, fatty, and acidic foods, as well as caffeine and carbonated beverages. Opting for a more alkaline diet, rich in fruits and vegetables, can help reduce acidity and prevent reflux.

Sleeping with an elevated upper body

Sleeping with the upper body elevated can help prevent stomach acid from flowing back into the esophagus and causing heartburn. Using additional pillows or a wedge pillow under the upper body can provide the necessary elevation. It is important to maintain a comfortable position to ensure quality sleep while keeping the upper body elevated.

Using antacids or other medications

Antacids, which neutralize stomach acid, can provide temporary relief from heartburn and acid reflux symptoms during pregnancy. However, it is essential to consult with a healthcare provider before using any medications, including over-the-counter antacids, as they may have potential side effects or interactions with other medications. A healthcare provider can recommend appropriate medications for managing heartburn and acid reflux.
