Why Do I Wake Up During the Night? 6 Common Causes That Interrupt Sleep

You wake up, look at the clock and spend a few seconds trying to work out what brought you out of sleep. Perhaps it was a noise, a thought, the need to get up or simply a feeling of discomfort. Then comes the next thought: “Will I be able to fall asleep again?”

Waking up during the night can happen occasionally without necessarily indicating a problem. However, if it happens repeatedly, it is worth paying attention to what comes before and after it. The cause is not always the same, and there is no single solution that works for everyone.

A Night-Time Awakening Does Not Necessarily Mean You Have a Sleep Problem 

Sleep is not one completely uninterrupted period. Brief awakenings can occur between sleep stages, and you may not even remember them in the morning. What matters more is whether you wake up frequently, stay awake for a long time or feel tired the following day.

If it happens once in a while, it may be linked to something simple, such as a warm room or an external noise. If it becomes a regular pattern, the following possible causes can help you understand where to start.

1. Your Mind Has Not Slowed Down

Sometimes your body is in bed, but your mind is still going over the day. An unfinished task, a difficult conversation or the schedule for the following day may come back to you when you wake up during the night.

Stress does not have to be intense to affect sleep. It may be enough to keep your mind alert. And when you open your eyes and start thinking about how many hours are left until morning, the tension can increase.

In this case, try to create a clearer transition into the evening. Leave some time between your daily responsibilities and going to bed, dim the lights and avoid turning a night-time awakening into an opportunity to plan or solve problems.

2. Something in Your Bedroom Is Waking You Up

Light, noise and temperature can interrupt sleep without you immediately realising it. Bright early-morning light, noise from the street or a room that is too warm may be enough to wake you up.

Think of your bedroom as a whole. You do not need to change everything. It may be enough to reduce a source of light, improve ventilation or remove a source of noise.

If you wake up because you cannot find a comfortable position, consider your sleep surface, too. A mattress that no longer supports you as it once did, or a pillow that does not suit your sleeping position, may contribute to more frequent awakenings. Explore the mattress range from CANDIA and compare the options to find what best suits your sense of comfort.
 

3. Your Evening Routine Has More of an Impact Than You Think

Coffee late in the day, nicotine and alcohol can affect how well you sleep through the night. Alcohol, for example, may make you feel sleepy more easily, but that does not mean your sleep will remain undisturbed until morning.

The same may happen after a heavy meal or spending many hours in front of a screen. You do not need to aim for a “perfect” routine. Try making small changes: see whether having your coffee earlier helps, leave more time between dinner and bedtime, or put screens away before going to bed.

4. Your Body Is Looking for a More Comfortable Position

Some awakenings start with physical discomfort. Pressure on your shoulder, discomfort in your lower back, a pillow that holds your head too high or a sleep surface that makes it difficult to change position can all disturb your sleep.

This does not mean that every night-time awakening is caused by your mattress or pillow. However, if you often wake up in the same position, keep trying to get comfortable or feel better when sleeping somewhere else, it may be worth taking a closer look at your sleep environment.

Explore the sleep pillows from CANDIA to discover different options based on height, feel and sleeping position. For more on the relationship between sleeping position, mattress and pillow, read our article Proper Sleeping Position: The Role of the Mattress.

5. Other Physical Needs May Be Waking You Up

Needing to use the bathroom during the night is a common reason for waking up. It may be influenced by how much fluid you drink late in the evening, medication or changes that occur in the body over time.

Other physical changes, such as feeling hot, night sweats or periods of hormonal change, may also interrupt sleep. It is not helpful to automatically attribute the cause to a single explanation. Pay attention to when it happens, how often it occurs and whether it affects your day.

If the symptom is new, severe or persistent, discuss it with your doctor. A proper assessment requires your personal medical history and cannot be made on the basis of an article alone.

6. There May Be an Underlying Sleep Disorder

In some cases, frequent awakenings are linked to sleep disorders. Pay closer attention if you notice any of the following alongside your night-time awakenings:

•  Loud snoring or pauses in breathing.
•  A sudden feeling of choking or gasping for air.
•  Excessive daytime sleepiness.
•  An uncomfortable urge to move your legs or restless sensations in your legs.

 

These signs do not constitute a diagnosis, but they are a reason to seek professional guidance. Sleep apnoea, restless legs syndrome and other conditions require assessment by a specialist.
 

What to Do When You Wake Up at 3 a.m.

The first thing that may help is to avoid turning waking up into a battle with the clock. If possible, keep your phone and the time out of sight. Calculating how many hours are left until morning will usually keep you more alert.

Stay in the dark for a while and try to relax your body. If quite some time passes and you are still not sleepy, get out of bed and go somewhere quiet. Read a few pages of a book or do something relaxing that does not involve bright lights or screens. Return to bed when you start feeling sleepy again.

The aim is to notice what happens before you fall asleep, what wakes you up and how you feel the following day. Sometimes the answer lies in a small change to your routine. At other times, a more careful assessment is needed. Both are worth approaching calmly.

Speak to a healthcare professional if night-time awakenings persist, affect your concentration or mood, or are accompanied by loud snoring, pauses in breathing, pain or other symptoms.
