Frequent Night Wakings

Q: Does a weighted blanket help you sleep through the night?

Yes. The steady pressure lowers stress hormones and increases serotonin production, making you less likely to start tossing and turning between sleep cycles.

Q: Why do I always wake up around 3:00 or 4:00 am?

This is often the point at which your body transitions into lighter REM sleep and your liver is very active. An early cortisol spike from stress can also wake you at this time.

Q: What should I do if I wake up at night and start worrying?

Leave your bed after 20 minutes of tossing and turning. Write your worries down and do a quiet activity in dim light. Only return to bed when you feel sleepy again.

Q: Does the bedroom temperature affect staying asleep?

Yes, a temperature between 16 and 18 degrees is ideal. A room that is too warm prevents the drop in body temperature needed for deep sleep.

Q: Can a magnesium supplement help me sleep through the night?

Magnesium supports muscle relaxation and the nervous system, which can help extend sleep duration and improve the quality of deep sleep.

Q: Why do I wake up with a dry mouth or feeling thirsty?

This may indicate mouth breathing or low humidity. Both can lead to lighter sleep, making you more likely to wake up from external triggers.

Q: Is it a good idea to check my phone if I wake up at night?

No. Blue light immediately suppresses melatonin production and tells your brain it’s daytime, which can make falling back asleep nearly impossible.

Q: What effect does cortisol have on night-time waking?

With chronic stress, an unwanted cortisol spike can occur during the night. This puts your body into a state of alertness, causing you to jolt awake in the middle of the night.

Q: Can snoring or sleep apnoea cause me to wake up?

Yes. Brief pauses in breathing force your brain to wake you momentarily to restore breathing, leading to a highly fragmented and restless night.

You can usually fall asleep without too much trouble, but around three o’clock you wake with a start and the tossing and turning begins. Staying-asleep problems can be just as exhausting as trouble falling asleep, because they interrupt the deep restorative phase of your sleep. This often leaves you waking up tired and unsettled.

In this article, we explain the causes behind this night-time waking and how you can extend your sleep.

Common causes of frequent night wakings problems

When you wake in the middle of the night, it’s often a sign that your body is being pulled out of deep sleep by an internal or external trigger.

Blood sugar fluctuations

An underestimated cause is blood sugar. If you consume a lot of sugar or fast carbohydrates in the evening, your blood sugar can drop during the night. Your body then releases adrenaline to correct this, leaving you wide awake.

Alcohol and sleep quality

Although alcohol may help you fall asleep faster, it significantly disrupts the second half of the night. Once the alcohol has been metabolised, sleep becomes lighter and more fragmented, leading to repeated waking.

The impact of environmental factors

As the night goes on, your sleep naturally becomes lighter. Outside noise, a change in room temperature, or a partner moving can then wake you more easily than earlier in the evening.

Tips to sleep through the night

The goal is to disrupt your sleep cycle as little as possible. Here are effective strategies to improve your ability to stay asleep.

Optimise your sleep environment with supportive tools

To eliminate external triggers, you can use specific products:

White noise: Ideal for neutralising sudden sounds (such as passing cars).
Sleep earplugs made to measure: For complete reduction of background noise.
Sleep mask: Prevents early morning light from activating your body clock too soon.

Limit fluids and heavy meals

Try not to drink too much in the two hours before bed to avoid night-time trips to the toilet. Also choose a light snack that helps keep blood sugar stable, such as a handful of nuts.

Frequently asked questions about staying-asleep problems

Is it normal to wake up once a night?

Yes, almost everyone wakes briefly during the night. It only becomes a problem if you lie awake for longer than 20 minutes, or if you don’t feel rested during the day.

Does a weighted blanket help you sleep through the night?

It can, although we believe more in the power of a wool duvet or blanket. It offers a similar effect but is far more user-friendly. The steady pressure and weight of the duvet encourages lower stress-hormone production throughout the night, making you less likely to start tossing and turning when you move between sleep cycles.

Why do I always wake up around 3:00 or 4:00 am?

This is often the point at which your body transitions from deep sleep into more REM sleep. It’s also the time when the liver is busiest processing substances (such as alcohol).

What should I do if I wake up at night and start worrying?

If you notice your mind starting to race, it’s important not to fight the thoughts. Try a short relaxation exercise, or jot your worries down on a note beside your bed to get them “out of your head”. Don’t stay in bed tossing and turning for more than 20 minutes, and use the breathing exercise to relax.

Does the bedroom temperature affect staying asleep?

Absolutely. A room that is too warm (above 18–19°C) can disrupt your sleep cycle. Your body temperature needs to drop slightly to remain in deep sleep. A cool, well-ventilated room is essential.

Can a magnesium supplement help me sleep through the night?

Magnesium is known as the “relaxation mineral”. It helps muscles relax and supports the nervous system, which can contribute to deeper, more uninterrupted sleep. If in doubt, always consult your doctor.

Why do I wake up with a dry mouth or feeling thirsty?

This may indicate that the room humidity is too low, or that you are mouth-breathing during sleep. Mouth breathing makes sleep lighter and can cause you to wake more easily. A humidifier may help.

Is it a good idea to check my phone if I wake up at night?

No, it’s one of the worst things you can do. Blue light signals to your brain that the day has begun, pushing you straight back into a more wakeful state. Keep lighting dim and avoid screens.

What effect does cortisol have on night-time waking?

Cortisol is your natural “wakefulness hormone”. Normally it only rises in the early morning to wake you up. However, with chronic stress, a cortisol spike can occur during the night. This can make you jolt awake around 3:00 or 4:00 am feeling alert, often with a racing heart.

Can snoring or sleep apnoea cause me to wake up?

Absolutely. Sleep apnoea causes brief pauses in breathing, prompting your brain to send an alarm signal to wake you so you start breathing again. You often don’t remember the pause, but you do notice that you suddenly wake up and have had a restless night.

Why do I need to go to the toilet so often at night (nocturia)?

While drinking too much before bed is an obvious cause, it can also be due to disrupted production of antidiuretic hormone (ADH) or prostate issues (in men). If you have to get up to urinate more than once a night, it can significantly disrupt your deep sleep cycles.
