Nighttime Awakenings: Why You Wake Up and How to Reclaim Restful Sleep

While various factors can disrupt your sleep, it should normally be easy to return to slumber. However, when sleep eludes you, and you find yourself tossing and turning, this may be a cause of concern. Explore the key reasons behind this phenomenon and discover effective tips to restore your sleep patterns, including what actions to take and avoid for a restful night.

9 reasons for waking up in the middle of the night

Waking up at night is quite common, with a study showing 35% of people experience disruptions at least three times a week. Things like a partner snoring, sudden brightness, temperature shifts, or noise can temporarily mess with your sleep. Most people, however, can quickly go back to slumber after such interruptions.

In other cases, one might keep waking up every night and struggle with falling asleep more often than usual, which could potentially indicate a more serious problem. In fact, there are quite a few factors — not necessarily medical — that may affect our sleep quality.

1. Circadian rhythm disturbances

Your body tries to align its sleep-wake routine with environmental cues, such as light and darkness, meal times, and exercise. When the body falls out of sync with these signals, it may suggest a circadian rhythm disorder. In such cases, individuals might experience frequent sleep difficulties, such as going to bed or waking up at unusual times.

2. Sleep disorders

Nighttime awakenings are a common symptom of sleep disorders. For instance, people with insomnia often wake up several times during the night and have a hard time falling back to sleep. In addition, obstructive sleep apnea (OSA) causes the airways to become blocked, eventually interrupting sleep. Nightmares are another reason for a restless night, making it harder to fall back asleep right away due to increased stress levels.

3. Mental health conditions

People dealing with mental health conditions like depression and anxiety may experience persistent thoughts or worries during nighttime. This can interfere with their ability to initiate or maintain sleep.

4. Other health issues

Some people may wake up during the night due to underlying health issues. One example is nocturnal high blood pressure, which causes symptoms such as frequent bathroom trips, snoring, breathing difficulties, and disrupted sleep. Other conditions like acid reflux, asthma, and dementia are also linked to frequent awakenings during the night.

5. Pain

It can be really hard to rest at night when you're dealing with pain. It's not just physical discomfort, pain is accompanied by mental problems such as anxiety and depression, making sleep problems even worse. Studies show that people with chronic pain are more likely to wake up in the middle of the night. They also take longer to get back to sleep once they’re awakened.

6. Older age

As we get older, our circadian system goes through changes that affect the regular patterns of our sleep-wake cycles. These changes can lead to shifts in our sleeping habits, like going to bed, getting up much earlier, and experiencing more frequent awakenings at night.

7. Hormones

Hormonal changes, like the ones occurring during pregnancy, perimenopause, and menopause, can make you more susceptible to waking up at night. Sleep problems are common among pregnant women, especially in the third trimester, with about 98% experiencing nighttime awakenings. In menopause, the decline in estrogen and progesterone production leads to symptoms like hot flashes, night sweats, and insomnia.

8. Medications

Some medications negatively impact sleep and contribute to nighttime awakenings. For example, beta-blockers, commonly used to treat high blood pressure, may suppress melatonin release, making it harder to sleep. In addition, using diuretics can result in frequent trips to the bathroom at night, which can disrupt sleep.

9. Lifestyle

The decisions you make regarding your lifestyle can also impact your ability to stay asleep. Those who smoke cigarettes often report having difficulties falling and staying asleep due to the stimulating effect of nicotine. Poor sleep hygiene can also contribute to waking up during the night.

What not to do when you wake up at night

Suppose you fell asleep as usual but found yourself opening your eyes in the middle of the night, long before your usual waking time. Before we talk about what to do in this situation, it’s important to be aware of the mistakes you should avoid.

One of the most frequent mistakes after waking up is turning on the lights. Exposure to light inhibits melatonin production, making it harder to fall back asleep. If absolutely necessary, consider using dim nightlights.

Another crucial rule to remember is not to reach out for your phone as soon as you wake up. Electronic devices emit blue light, which also disrupts melatonin production. Not only can this lead to poor quality sleep, but it can be harder to fall asleep since blue wavelengths increase alertness. It is also a good idea not to use any electronic devices in the hour before going to bed.

If you've been awake for more than 30 minutes and cannot fall back asleep, staying in bed longer can only make it more difficult. It's okay to get up and do something relaxing until you feel sleepy again.

How to go back to sleep if you don’t want to

Sometimes, it’s hard to get back to sleep when you’re woken up in the middle of the night — we’ve all been there. Luckily, there are various ways to help you relax and go back to sleep. See some examples:

  • Deep breathing. Take slow, deep breaths in through your nose and exhale through your mouth. Research suggests this activates the parasympathetic nervous system, promoting relaxation and helping you fall asleep.
  • Meditation. Evidence suggests that mindfulness meditation may improve the sleep quality of people dealing with sleep problems such as insomnia. You can find plenty of free apps and self-guided meditation audio online.
  • Progressive muscle relaxation (PMR). PMR involves tightening and then relaxing each muscle one by one. It’s a great way to let go of tension, reduce anxiety, and get into a more calm state for sleep.
  • Guided imagery. This technique encourages you to imagine peaceful scenarios to help you relax and doze off effortlessly.
  • Calming music. One study showed that people who listen to music at bedtime tend to fall asleep more quickly and experience fewer awakenings at night.
  • Journaling. If your mind is racing, try keeping a notebook by your bed. Writing down all your worries may help you clear your mind and relax.

How can you sleep the whole night?

Many sleep disruptions can be sorted out by adopting healthier sleep habits. It all starts with a consistent bedtime and wake-up schedule as well as setting up a calm and relaxing environment; in other words, your bedroom should ideally be meant only for sleep and sex, and no TVs or other disrupting devices should be present.

What you do in the hours before sleep also largely affects your nighttime. It's best to avoid consuming heavy foods, caffeinated drinks, and alcohol at least a few hours before bedtime, and intense physical activities should be put aside for the first half of the day, if possible.

If waking up at night persists, and none of the tips help, it may be time to consult a professional for further guidance.

When to seek help

Waking up and being unable to fall back asleep could be a sign of a health issue or sleep disorder. If improving your sleep habits doesn’t help with nighttime wake-ups, talking to a professional is advisable.

People wake up at night for many reasons, like noise or temperature changes, but they easily go back to sleep. If you find yourself frequently waking up and struggling to sleep, don't worry – you can get uninterrupted sleep again. Figuring out what's causing the problem can make a big difference in getting a good night's sleep. Just reach out for help.
