Waking up at night is normal

You jolt awake at 2:47 AM. Again. Same time as last night. Your mind starts racing: “What’s wrong with me? Why can’t I sleep through the night like I used to?”

Here’s what might surprise you: There’s probably nothing wrong at all. Waking during the night is not only common—it’s completely normal.

The Eight-Hour Sleep Myth

We’ve been sold a lie about sleep. The cultural expectation is that “good sleep” means eight hours of continuous unconsciousness, where you drift off at 10 PM and wake refreshed at 6 AM without a single interruption.

But that’s not how human sleep actually works.

Most adults wake up 2-3 times per night. particularly as we get older and for women, after menopause. If you’re waking up during the night, you’re not broken—you’re human.

How Humans Actually Slept (Before We Messed It Up)

For thousands of years, historical records describe human sleep patterns very differently from what we expect today. Our ancestors didn’t sleep for eight hours straight. Instead, they experienced what was called “first sleep” and “second sleep.”

The pattern went like this: 3-4 hours of deeper sleep after sunset, followed by a period of wakefulness lasting up to two hours, then dozing through the remainder of the night until sunrise.

You’ve probably heard old sayings like “an hour of sleep before midnight is worth two after midnight.” These sayings are over 500 years old and reflect historical experiences of human sleep.

So what changed?

Industrialisation in the 18th century created pressure for workers to sleep in a single consolidated block, maximising time available for factory work. Gas and electrical lighting in the 19th century pushed wakeful activity further into the night. Sleep became something we were supposed to get done efficiently, in one go, ideally in under eight hours.

We essentially re-engineered human sleep to suit industrial capitalism, not human biology.

Why You Wake Up at (Almost) the Same Time Every Night

Here’s something that frustrates many people: waking at the same time every night, or with remarkable regularity—say, every 90 minutes.

Before you panic, here’s the truth: This is actually a sign that your sleep is working perfectly.

We sleep in cycles, each lasting 60-120 minutes. At the end of each cycle, we naturally come closer to the surface of sleep before descending into the next cycle. If something disturbs you during that lighter phase—a distant noise, a shift in body position, a dream—you might fully wake up.Your body’s internal clock is so well synchronised that it brings you to this lighter sleep phase at the same time each night. Rather than being a symptom of a problem, this regularity demonstrates that your sleep mechanisms are functioning extraordinarily well.

Other Reasons We Wake Up

Sleep cycles aren’t the only reason for nocturnal awakenings. As we age, our bodies become less able to completely “shut down” for long periods. Instead, we need periodic “maintenance” breaks:

• Bathroom needs – Nocturia increases with age
• Pain or discomfort – Arthritic joints, restless legs, or simple positional discomfort
• Breathing – Shortness of breath or sleep apnoea can cause awakenings
• Temperature changes – Hot flushes or room temperature fluctuations

All of these become more common as we get older. They’re not signs that your sleep is failing—they’re signs that you’re adapting to changing physical needs.

The Type of Sleep That Feels Like Being Awake

Around 30% of normal sleep consists of lighter sleep where we have some awareness of our environment. For people with chronic physical or mental health conditions, this can be as high as 70%.

This creates a confusing situation: You’ve actually been asleep, but because you had some awareness during that sleep, it feels like you were awake the whole time. People often drastically underestimate how much sleep they’re getting because of this phenomenon.

This is why I strongly caution against chasing “continuous unawareness” with sedative medications. That deeply unconscious sleep people remember from their teenage years isn’t the natural state of adult sleep, particularly for those managing health conditions.

What to Do When You Wake Up at Night

First and most importantly: Don’t panic. Don’t get frustrated. Don’t start calculating how many hours of sleep you’ve lost.

The frustration itself often becomes the problem. When you wake at 2 AM and immediately think “Oh no, not again, I’ll never get back to sleep,” you’ve just triggered your stress response—which definitely won’t help you get back to sleep.

Instead, if you find yourself awake:

1. Stay calm. Remind yourself that waking is normal.

2. Don’t try to sleep. If you’re awake and sleep feels far away or you find yourself frustrated, trying to get back to sleep, break that cycle. Sit up and read, or get out of bed.

3. Do something boring. This is where stimulus control comes in. Have a plan before you go to bed of what you will do if you wake during the night: a designated chair, a boring book, a simple puzzle, low lighting. Not your phone. Not work emails. Not anything engaging.

4. Return to bed when sleepy. Not when exhausted, not on a schedule—when you feel genuinely sleepy.

The goal is to maintain the association between your bed and sleep, not lying awake feeling frustrated.

When to Seek Help

While waking during the night is normal, consistently having trouble getting back to sleep isn’t something you need to live with. If you’re regularly awake for extended periods and it’s affecting your daytime function, talk to your GP or a sleep physician.

There may be underlying issues worth investigating—sleep apnoea, restless legs syndrome, circadian rhythm disorders, or other conditions that can be effectively treated.

The Bottom Line

Modern life has given us unrealistic expectations about sleep. We think we should collapse into unconsciousness and wake eight hours later feeling refreshed, with no awareness of the time in between.

That’s not broken sleep—it’s a broken expectation.

Your ancestors woke during the night. Your body is designed to cycle through sleep stages that bring you closer to wakefulness several times per night. This is normal. This is natural. This is how sleep works.

The problem isn’t your sleep—it’s the standard you’re judging it against.

If you find that you’re waking more than you think you should and consistently having trouble getting back to sleep, it’s worth talking to your health professional.
