Why do I keep waking up early during pregnancy? 11 possible causes and 12 products that could help (2024)

If you're wondering why you keep waking up early during pregnancy, you're not alone. Many people experience a shift in their sleep pattern, here are some of the reasons why...

For many, pregnancy isn't exactly the most comfortable time of their lives, and this can often lead to difficulty sleeping. Whether it's the baby kicking and pressing on your bladder or thoughts about what being a mother might be like keeping you up, there are plenty of reasons why you might find yourself needing to know how to recover from a bad night's sleep - especially now coffee is no longer an option. Waking up early every morning is another common complaint, and combined with a night of tossing and turning it can leave you looking for ways to look less tired and get rid of dark circles.

If that sounds like you, don't worry, you're not alone and it's totally normal. But that doesn't mean it's not annoying. Dr Hana Patel, resident sleep expert atTime4Sleep explains, "Sleep disturbances during pregnancy are quite common, especially during the first trimester. Causes of insomnia during pregnancy may include nausea, heartburn, general physical discomfort and frequent trips to the bathroom. Many women also report instances of sleep apnea and leg cramps during this period. These physical symptoms can disturb your natural sleep cycle, leaving you feeling less rested in the morning."

We've spoken to Dr Hana and other sleep experts to put together a list of reasons why you keep waking up early in pregnancy, and we've researched the products that can help you get a more restful night in future.

Why do I keep waking up early in pregnancy?

1. Hormones

Your body is going through a lot of changes during pregnancy, and hormones are the culprit for many side effects over the nine months - including changes to your sleep. This is particularly the case in the first trimester, when rising levels of progesterone often make people feel more sleepy and fatigued.

Unfortunately, this doesn't always equal a longer night's sleep. A study published in the Journal of Biological Rhythms suggested that women shift their daily schedules earlier by up to a few hours during the first third of their pregnancy. The experiment involved 39 women wearing wristwatches that continuously monitored their daily activity and rest both before and during pregnancy.

While the study found that women's daily schedules gradually returned to normal before giving birth, another study published in the Journal of Clinical Sleep Medicine found that oxytocin, the hormone responsible for uterine contractions, peaks at night and may cause sleep fragmentation in late pregnancy.

2. You're wearing the wrong clothes to bed

In the winter, as the temperature drops, we're more inclined to bundle up in thermal pyjamas to keep the heat in. But if you're currently pregnant you might find that you're often waking up hot and sweaty - this is partly due to the hormones, but also a result of an increase in blood supply to the skin. And did you know that by the eighth week of pregnancy, your heart is pumping blood20 percentfaster?

While you might feel cold at the beginning of the night, wearing linen pyjamas is one of the best ways to ensure that your temperature stays regulated while you sleep during the winter months. This is because the material has thermo-regulating characteristics, which means the breathable fabric allows heat to escape during summer while serving as an insulator during winter.

3. Your bedroom is too warm

Similarly, a sleep environment that is too warm may cause you to wake up early in pregnancy. While you might have been able to sleep through before conceiving, those warmer temperatures could be the reason your sleep is now disturbed.

Sleep behaviour and environment expert James Wilson, akaThe Sleep Geek, says, "Our body is very sensitive to changes in core temperature when it comes to sleep." He adds, "Consider what your mattress is made from. Foam mattresses make you hotter, so to help your body manage its temperature then sprung mattresses with natural fillings may be more helpful."

James also suggests having a separate duvet to your partner, as sharing might mean their body heat will make you hotter, whereas separate sleep environments allow you both the chance to manage your temperature better.

4. Discomfort

There are many side effects from pregnancy that may cause you discomfort while sleeping. Common complaints include heartburn, back ache, nausea, bloating and constipation. In addition, there's a link between restless leg syndrome and pregnancy, with the NHS explaining that about one infive pregnant women will experience symptoms in the last three months of their pregnancy - although it's not clear exactly why this is.

The main symptoms include an overwhelming urge to move your legs, but it can also cause an unpleasant crawling or creeping sensation in the feet, calves and thighs. One of the treatments is regular exercise in the daytime.

Meanwhile, Dr Hana Patel offers some advice for easing discomfort during pregnancy: "It is usually recommended to sleep on your left side if possible, as this can facilitate blood flow to major organs and to the foetus. If you can, try to get into a habit of doing this early on - if you are not usually a side sleeper as this will help you become more comfortable in the long term."

You could also try using a pregnancy pillow, which assists in sleeping comfortably on your side and can support your back, neck, knees, hips and growing belly.

5. Spending too much time in bed

It's normal to feel fatigued during pregnancy, but getting into bed early on in the day might not be the best idea for creating a good quality sleep environment. This is because the more time you spend in bed doing other things like relaxing, watching television or even working, the more your brain associates bed with a place of movement rather than sleep.

Hypnotherapy Directory member Penelope Ling explains that the best way to solve this problem is to "Only use your bed for sleep, if you have difficulties sleeping." She adds, "Then our brains associate the bed only with sleep, instead of being the place you do everything else. No computing, no TV, no spending hours chatting with friends - just sleep."

6. Sleep apnea

Sleep apnoea is when your breathing stops and starts while you sleep, and research in the Obstetrics and Gynecology Clinics of North America journal found that it may affect as many as26 percentof all pregnancies.

While not usually dangerous, in pregnancy sleep apnea can have adverse consequences, including increasing your risk of high blood pressure and making you more likely to develop gestational diabetes andpreeclampsia.

Common symptoms, according to the NHS, include:

• Breathing stopping and starting again
• Making gasping, snorting or choking noises during sleep
• Waking up a lot in the night
• Loud snoring

According to Dr. Michael Breus, otherwise known as the Sleep Doctor, "REM sleep is concentrated more heavily in the last half of the night, which means people with sleep apnea may be more likely to be awakened in the very early morning as a result of their sleep-disordered breathing."

If you have any of the symptoms of sleep apnea, you should see your GP, they may refer you to a specialist sleep clinic for tests. The NHS advises that if someone else has seen you have the symptoms, it can help to bring them with you to the GP.

7. Lacking in magnesium

8. Too little exercise

We get it, pregnancy can leave you feeling fatigued and, especially in the later stages, you're exhausted just from walking up the stairs, let alone a full-on workout. But if you've found that you've been less active since falling pregnant then this might explain why you're waking up early.

Nick Littlehales, Elite Sport Sleep Recovery Coach, explains that adding more exercise to your daily routine could help prevent sleep difficulties. "Abalanced approach to exercise will avoid crashin into sleep between 9pm and 12am and then woken around 2/3am feeling either unrefreshed or wide awake. Once that becomes the norm then the only way out is to reset, before other counterproductive behaviour adjustments kick in."

It doesn't have to be intense exercise either, as onestudy by researchers at Brandeis Universityfound that taking more steps during the day may be related to better sleep at night. Meanwhile, yoga has been shown to be particularly effective for women struggling to sleep during pregnancy, as one study published in the journal Complementary therapies in clinical practice found that pregnant women who practiced yoga hadreduced sleep disturbances.

9. Needing the toilet

Pregnancy is often associated with an increased need to go to the toilet. It can start very early on, due to hormonal changes and increased blood flow, but is especially common in the later stages when the growing uterus puts pressure on the bladder. While it's nothing to worry about, it can be very annoying.

Unfortunately, it's a relatively unavoidable problem. It's not recommended to drink less, as it's important to stay hydrated, but you could try to drink an adequate amount of water earlier in the day and avoid drinking too much right before bed. You can also cut out diuretics - which increase urine production - such as coffee, tea and any soft drink containing caffeine. Celery, ginger and watermelon are also known to be diuretics.

10. Insomnia

Insomnia is characterised by having trouble falling asleep or staying asleep. "Insomnia affects one in three people at some point in their lives, and it can manifest itself in a few, very uncomfortable ways." Shamir Patel, pharmacist and founder of Chemist 4 U assures us.

"It can make it difficult to fall asleep in the first place – causing long hours of distress – or it can mean that people find it hard to stay asleep during the evening. Some people may find that they wake up far earlier than they would like and then find it difficult to get back to sleep.

"Often, people with insomnia will feel very tired when they do wake up and will experience extreme tiredness during the day. The stress that this causes can often exacerbate the problem."

Sleep difficulties such as insomnia are common during pregnancy. While there's no quick fix, the NHS recommends trying the following for pregnant people who are suffering:

• If you can, nap during the day and get some early nights during the week
• Avoid tea, coffee or cola drinks in the evening, as the caffeine can make it harder to go to sleep
• Try to relax before bedtime so you're not wide awake - you can ask your midwife for advice or you antenatal classes may teach you some techniques
• You could join an antenatal yoga or pilates class, or try other physical activity such as walking more or swimming

11. Anxiety

Anxiety during pregnancy - also known as perinatal anxiety - is very common. Pregnancy is a big life change and, coupled with the differences in your body and the plans that need to be made for your new arrival, it's understandable if you're often experiencing feelings of worry.

"When there are stressors in our lives, our physiology gears up for a fight-or-flight response that can contribute to sleepless nights and anxious dreams." Melinda Powell, UKCP psychotherapist and author of The Hidden Lives of Dreams, explains. "Up to 50 per cent of dream content thematically relates to emotions experienced the day before, so, essentially, anxiety dreams act as a form of nocturnal therapy, helping us to work through our fears and concerns. They may even have a role in moderating our fears in waking life – making us less reactive and so more able to act more responsively in our daily lives."

Dr Hana Patel offers her advice for those struggling with anxiety: "Sleeplessness can often be caused by stress and anxiety - remember that this is a time in which you should be prioritising rest! Insomnia, combined with feelings of low mood or hopelessness can also be a sign of depression in some cases, so be sure to talk to your healthcare provider if you are experiencing difficulty with your mental health."
