When it comes to pregnancy, it is often thought that a woman can comfortably sleep all day, but sleep problems during pregnancy are quite common. It is estimated that two-thirds of pregnant women experience insomnia at some point during their pregnancy.

This lack of sleep can lead to some problems during pregnancy, and some studies have shown a relationship between insufficient sleep and longer labor times and increased likelihood of cesarean delivery. Additionally, a constant state of insomnia is associated with the risk of pregnancy hypertension, preeclampsia, gestational diabetes, or depression, so it is necessary to pay attention to and take this condition seriously.

We will try to explain the causes of insomnia during pregnancy, the normal changes in sleep patterns during each trimester, the symptoms that indicate you should seek help, and most importantly, how you can solve this with practical and safe measures.

Changes in Sleep Patterns During Pregnancy

Although a large part of these sleep disorders is caused by hormonal changes brought about by pregnancy, physical changes (weight gain, digestive disturbances, cramps, fetal movements) and emotional changes (fears, anxiety, stress) also play a role. The changes vary according to the stage of pregnancy, so sleep patterns change in each trimester.

Additionally, insomnia during pregnancy often comes with a range of symptoms: difficulties falling asleep, frequent nighttime awakenings, feelings of inadequate restorative sleep, and daytime fatigue, irritability, and drowsiness. Understanding what happens at each stage will help you develop strategies that are more suitable for your situation.

First Trimester

We begin to feel significant changes in our sleep patterns during the first trimester. For many women, this is the first sign that something is changing in the body, accompanied by nausea.

On one hand, the main hormone of pregnancy, progesterone, causes you to feel very drowsy during the day. You may notice that you can sleep anywhere, even during times when you were very active before. However, at night, sleep is often more superficial, and frequent awakenings occur. Even if you feel like you have slept for long hours, it is common to feel that you have not truly rested.

On the other hand, the body has to increase blood volume, so there is fluid retention and more blood in circulation. This increase, along with the effects of certain hormones, causes the kidneys to work harder and increases urine production. As a result, the need to go to the bathroom several times during the night is quite common, and it can often be difficult to fall back asleep.

Additionally, nighttime nausea, vomiting, heartburn, or reflux may also occur, making it difficult to fall asleep. Daytime drowsiness and nighttime superficial sleep characterize the early weeks for many pregnant women.

Second Trimester

Generally, the second trimester is the best period in many ways. Although sleep disorders do not completely resolve, there is a noticeable improvement compared to the beginning of pregnancy.

The effects of the progesterone hormone continue, so the feeling of daytime drowsiness decreases, but at night sleep still remains somewhat superficial and awakenings occur; however, many women find this more tolerable.

Almost certainly, you will sleep uninterrupted for 3 or 4 hours at the beginning of the night, and then you will feel that you have difficulty falling back asleep after the first awakening. Indeed, even if you have slept intermittently, this sleep is superficial and may not always be restorative.

Nightmares and very vivid dreams may arise during this period. Many mothers complain about strange dreams related to pregnancy, the baby, or childbirth that occur during the second trimester and continue until the end. This is due to the expression of our brain's fears and anxieties about the unknown; these worries may remain in the background while awake, but they emerge strongly during sleep.

Although the second trimester is perceived as a "calmer" period, it is important to maintain sleep hygiene routines (regular hours, suitable environment, light dinners, etc.) from now on, as this will lay the foundation for better coping with future changes.

Third Trimester

At this stage, the baby is quite heavy and active. Its size, position, and activity level directly affect your rest. It moves constantly and wakes you up frequently, so you will need to reach a "compromise" regarding sleep positions with it.

You may be comfortable in one position, but if the baby does not feel comfortable in that position, it will not stop moving. Its sleep rhythm is different from ours, and they do not sleep continuously for long periods in the womb. They take many short naps there, so it is natural to feel as if they are almost never still.

At this stage, the need to urinate increases very frequently. Due to the weight of the baby, the bladder is compressed and its capacity decreases significantly; therefore, even small amounts of urine can trigger the urge to go to the bathroom.

Additionally, snoring may begin. This is due to the uterus compressing the diaphragm and making it difficult for the lungs to expand. Also, airflow may decrease due to nasal congestion caused by pregnancy, which increases snoring. Sometimes it can be so loud that it can wake you up or cause your partner to say you are snoring more.

Snoring is quite common during pregnancy and is usually normal. However, it can sometimes be associated with real health issues, such as obstructive sleep apnea syndrome, which requires evaluation.

If you feel apnea or shortness of breath during snoring, do not hesitate to consult your doctor. A typical feature of sleep apnea is experiencing loud snoring accompanied by wheezing, pauses in breathing, or a feeling of choking.

If you have been diagnosed with hypertension, preeclampsia, diabetes, or another complication during pregnancy, you should consult your doctor when snoring begins, even if you do not have a clear feeling of apnea. In these cases, insomnia complications can worsen, so it is important to assess the situation early.

Insomnia Symptoms to Know During Pregnancy

Recognizing the symptoms helps you understand which discomforts are normal during pregnancy and in which situations you need to seek professional help. The most common symptoms are:

  • Difficulty falling asleep even if you feel tired, taking longer than usual.
  • Difficulty maintaining sleep, with frequent awakenings throughout the night.
  • Waking up too early, with an inability to fall back asleep.
  • Feeling of inadequate restorative sleep, feeling that you cannot rest even after spending long hours in bed.

During the day, the following may also occur:

  • Excessive daytime sleepiness, with a desire to sleep at inappropriate times.
  • Irritability and mood swings due to lack of rest.
  • Difficulties with attention and concentration, small forgetfulness, and feeling "heavy".
  • Increased anxiety or sadness, which can also feed into insomnia.

If you are consistently identifying several of these symptoms, it is recommended to share the situation with your midwife or doctor so they can assess whether a more specific approach is needed, especially if it is accompanied by hypertension, gestational diabetes, suspected depression, or severe anxiety.

Main Causes of Insomnia During Pregnancy

There can be many and varied reasons for insomnia during pregnancy. Often, multiple factors come together, so it is not always easy to identify a single cause. The most common causes include:

  • Hormonal changes affect circadian rhythms and sleep depth.
  • Physical discomforts, such as back pain, cramps, heartburn, or increased frequency of urination.
  • Baby's movements, especially in the third trimester and the last weeks.
  • Concerns about the fetus's health, birth, and life changes.
  • Unhealthy sleep habits, such as using screens in bed, irregular hours, or heavy dinners.

Some factors are particularly common during pregnancy:

  • Heartburn or gastroesophageal reflux: progesterone relaxes the lower esophageal sphincter, and as there is less space for the stomach, digestion slows down and makes it easier for stomach contents to rise into the esophagus while lying down.
  • Increased frequency of urination: the growing uterus puts pressure on the bladder, and having more fluid in circulation necessitates trips to the bathroom several times during the night.
  • Muscle aches and cramps in the legs or feet: very common at the end of the day, which can cause sudden awakenings and make it difficult to fall back asleep.
  • Postural discomfort: as the belly grows, it becomes difficult to lie on your back or stomach.

Understanding which factor is more effective in your case will help you better choose sleep hygiene measures and lifestyle changes.

Effects of Poor Sleep During Pregnancy

Insomnia problems during pregnancy are quite common and in most cases are not a sign of a serious illness. However, as the duration of insufficient sleep increases, it can have consequences for both mother and baby.

For the mother, conditions associated with a lack of quality sleep include:

  • Increased risk of pregnancy hypertension and preeclampsia, especially when combined with other risk factors.
  • Increased likelihood of gestational diabetes and difficulties in glucose control.
  • Increased pain perception, especially in the back, pelvis, and joints.
  • Increased anxiety and depression symptoms, with more irritability and feelings of being overwhelmed.
  • Excessive daytime fatigue, making it difficult to be productive at work, care for other children, or engage in daily activities.

For the baby, various studies have observed that continuous maternal insomnia is associated with the following conditions:

  • Increased risk of intrauterine growth restriction, resulting in babies that are slightly smaller than expected.
  • Increased likelihood of preterm birth or induced birth due to maternal complications.
  • Increased cesarean rates, as the mother may be more fatigued and have a reduced capacity to respond during labor.

Considering all this, paying attention to rest during pregnancy is not a luxury, but rather an important part of self-care and the health of the baby. Improving sleep quality is part of holistic management during pregnancy, along with nutrition, exercise, or monitoring blood pressure.

What Can I Do to Manage Insomnia During Pregnancy?

It is not recommended to take medication on your own during pregnancy. However, with your doctor's recommendation, some medications or treatments may be used when non-pharmacological measures are insufficient; sleep should primarily be addressed with habit changes and psychological support if necessary.

Do not take anything without consulting your specialist. Although there may be cases where your acquaintances or family members have been treated successfully, the specific conditions of each pregnancy make generalization impossible. In fact, some "natural" or herbal products can be dangerous during pregnancy.

Most mothers manage to control insomnia by improving sleep hygiene. This includes making simple changes to daily routines, nutrition, sleep times, and resting environments; when these changes are maintained, they can make a significant difference.

Sleep Hygiene Habits for Better Rest

It is best to set very simple rules that will help us fall asleep and have a restful sleep:

  • Good nutrition. Nutrition is a key component. Avoid heavy, spicy, or fatty foods, especially in the evening. Never skip dinner: having an early and light dinner, a meal containing complex carbohydrates, protein, and healthy fats helps prevent sugar drops throughout the night.
  • If you are cooking at home and feel very tired, you can take a short nap of 10 or 15 minutes. This will help you feel better and will not affect your nighttime sleep.
  • Ensure good hydration by drinking water throughout the day. However, reduce fluid intake a few hours before going to bed to decrease the need to go to the bathroom.
  • Go to the bathroom before bed. This way, the need to empty your bladder will arise later, allowing you to sleep longer at the beginning of the night.
  • Avoid stimulants in the hours after noon. Caffeinated beverages, such as coffee, tea, or cola, are stimulating and diuretic, making it difficult to fall asleep and stay asleep.
  • Do some exercise during the day, but never in the hours before bed. Activities like walking, light swimming, or prenatal yoga improve sleep quality and reduce anxiety.
  • Wind down before bed. Engaging in too much stimulating activity (working, intense exercise, tense conversations) right before sleep makes it difficult to fall asleep. The same applies to electronic devices like computers, tablets, or smartphones: the blue light they emit reduces melatonin production. It is better to read a book or engage in calming activities before sleep.
  • Go to bed as soon as you feel sleepy. Waiting too long can cause you to lose the feeling of needing to sleep.
  • Have a glass of warm milk before bed. This is a classic "grandma remedy." The proteins in milk and the warmth help with relaxation. Grandmothers often add honey or sugar; this depends on your weight gain and gestational diabetes risk.
  • Ensure the room is cool and well-ventilated. It becomes harder to fall asleep in hot weather, and pregnancy also increases body temperature.
  • Adopt a comfortable position. If you are in the third trimester, you will also need to adapt to the most comfortable position for the baby.
  • Try not to make to-do lists in bed or mentally review the next day. To clear your mind, it is better to write down tasks on paper.
  • Use relaxation techniques. A midwife teaches deep breathing, visualization, or progressive muscle relaxation exercises. Practice these every day so they are more effective when you need them.

Positions and Pillow Support for Better Sleep

Position is key for quality rest. From the second and especially the third trimester onwards, the following are recommended:

  • Sleep on your side, preferably on your left side. This position increases blood circulation, improves the delivery of nutrients and oxygen to the placenta, and reduces pressure on the vena cava on the right side.
  • Avoid lying on your back for long periods, as the weight of the uterus can put pressure on the vena cava and may cause dizziness, discomfort, or even drops in blood pressure.
  • Place a pillow between your legs to align your hips and alleviate pressure in the lower back area.
  • If you feel tension or heaviness in your abdomen when lying on your side, place a pillow under your abdomen.
  • Elevate the head of the bed slightly with pillows or a support if you experience significant reflux or a feeling of choking in a lying position.

"Nursing pillows or ergonomic pillows for pregnancy" can be very helpful: they conform to body shape, support the abdomen and legs, and help maintain the side position effortlessly.

Psychological Support and Therapy for Insomnia During Pregnancy

In many cases, sleep hygiene measures are sufficient, but if insomnia persists and is associated with intense anxiety, constant worry, or a very low mood, psychological support can be greatly beneficial.

Cognitive behavioral therapy for insomnia is the preferred treatment for pregnant women. In a short time, a qualified psychologist or psychiatrist:

  • Assesses your personal situation, identifying your fears related to pregnancy and childbirth and the factors contributing to insomnia.
  • Corrects misconceptions about sleep, such as thoughts like "if I don't sleep for 8 hours, the baby will be harmed" or "I'll never be able to sleep well again."
  • Teaches emotional regulation, relaxation, breathing, and pregnancy-appropriate mindfulness techniques.
  • Helps you create realistic rest routines that are compatible with your work and family life.

If there is a history of intense anxiety, depression, or emotional issues, this psychological support not only improves sleep quality but also reduces the risk of postpartum depression and facilitates a better bond with the baby.

What About Medication Use for Sleep During Pregnancy?

In some cases, especially when insomnia is very severe and previous measures have not worked, the specialist may evaluate medication use. In every case, a balance is struck between the risks of not treating insomnia (such as maternal exhaustion or worsening of underlying conditions) and the potential effects of medications.

Some groups of medications that may be used include:

  • First-generation antihistamines, such as doxylamine, induce sleepiness and are considered relatively safe when used under medical supervision during pregnancy.
  • Some short-acting hypnotics or benzodiazepines may be considered in very selective situations, always at the lowest effective dose and for the shortest duration possible.
  • Some sedative antidepressants may be used when insomnia is associated with significant depression or anxiety, and only when deemed necessary by the specialist.

Supplements that seem harmless, such as melatonin or some "relaxing" herbs, have not been sufficiently researched during pregnancy and may lead to adverse effects or even a risk of miscarriage in some cases. Therefore, they should not be taken without a clear recommendation from a doctor.

Still, if insomnia is not improving or is worsening, consult your doctor: they will evaluate treatment options based on your specific situation, taking into account your pregnancy period and history, and will clearly explain the safest options.

Insomnia during pregnancy often significantly improves after the baby is born. Nevertheless, learning to maintain your rest, manage anxiety, and listen to your body's needs now will also be a valuable tool for postpartum and baby care.
