5 Myths About Insomnia That Are Making Your Sleep Worse

If you’ve spent any time searching for answers to your sleep problems, you’ve probably absorbed a small library’s worth of advice. Some of it is solid. A surprising amount of it isn’t — and a few persistent myths may actually be keeping you awake.

Before we get into the deeper stuff, let’s clear the table of a few popular misconceptions that deserve a quick send-off.

A nightcap will help you sleep. It won’t. Alcohol might make you drowsy, but it fragments your sleep architecture — particularly REM and deep sleep — leaving you more likely to wake at 3 a.m. staring at the ceiling. Napping makes up for a bad night. Tempting, but napping during the day reduces your sleep drive, which is the very pressure your brain needs to fall asleep that night. For people with insomnia, napping often perpetuates the cycle rather than breaking it. Sleeping pills are the most effective treatment for insomnia. They’re not. The American College of Physicians, the American Academy of Sleep Medicine, and the European Sleep Research Society all recommend Cognitive Behavioural Therapy for Insomnia (CBT-I) — not medication — as the first-line treatment for chronic insomnia. Pills can offer short-term relief, but they don’t address the patterns that keep insomnia going.

Now, those myths are fairly straightforward to debunk. But some insomnia myths are sneakier. They sound reasonable, feel true, and quietly make things worse. Let’s look at five of them.

Myth 1: Everyone Needs 8 Hours of Sleep

This one is everywhere. It’s on wellness blogs, in fitness magazines, and probably stitched onto a throw pillow somewhere. But the idea that every adult needs exactly eight hours of sleep is a myth — and for people struggling with insomnia, it can be a genuinely harmful one.

Sleep need is biologically determined and varies from person to person. The actual range for healthy adults runs from roughly six hours to over ten, with seven being the minimum most sleep researchers recommend. Families tend to share similar sleep needs, just like they share height or eye colour. You can’t train yourself to need less, and you can’t will yourself into needing more.

Why Chasing a Number Backfires

Here’s where the damage happens. If you believe you need eight hours and you’re only getting six and a half, you start to panic. You go to bed earlier “just in case.” You lie there doing mental arithmetic — if I fall asleep right now, I’ll get seven hours and forty-two minutes. That arithmetic is not relaxing. It’s the opposite.

This kind of sleep-related anxiety is one of the things that CBT-I directly targets. By challenging unrealistic beliefs about how much sleep you need, you remove one of the biggest sources of nighttime pressure. And when the pressure drops, sleep often gets easier.

A more useful question than “Am I getting eight hours?” is “How do I feel during the day?” If you’re functioning well on seven hours, that might simply be your number.

Myth 2: Insomnia Is Just Stress — It’ll Go Away on Its Own

There’s a grain of truth here, which is what makes it sticky. Stress absolutely can trigger insomnia. A job loss, a health scare, a relationship falling apart — any of these can send your sleep sideways for days or weeks. And sometimes, when the stressor resolves, the sleep does come back.

But not always. And this is where people get stuck.

Sleep researchers use something called the 3P model to explain how insomnia develops and — more importantly — why it persists. The three P’s stand for predisposing factors (your baseline vulnerability), precipitating factors (the thing that triggered it), and perpetuating factors (the behaviours and thought patterns that keep it going). Stress lives in the “precipitating” category. But the perpetuating factors — going to bed too early, lying awake trying to force sleep, catastrophizing about tomorrow — those take on a life of their own.

How Does Insomnia Become Chronic?

The cruel irony is that most of the things people do to cope with a bad stretch of sleep are the very things that turn it chronic. You start spending more time in bed. You cancel plans to rest. You drink more coffee to get through the day, then wonder why you can’t settle at night.

The original stressor might be long gone, but now your brain has learned a new habit: bed equals wakefulness. The insomnia is no longer about stress. It’s about what happened after the stress.

This is also why insomnia often shows up alongside depression, anxiety, chronic pain, and other conditions. It’s rarely a single-cause problem — and waiting for it to resolve on its own can mean waiting a very long time. In Canada, over 90% of people with insomnia symptoms report having them for more than a year.

Myth 3: You Can Catch Up on Lost Sleep Over the Weekend

This one feels intuitively right. You had a rough week, so you sleep in on Saturday and Sunday to “recharge the batteries.” Problem solved.

Except your circadian rhythm doesn’t work like a bank account. You can’t deposit extra hours on the weekend to cover a weekday deficit. What you’re actually doing is shifting your internal clock — going to bed later and waking later — which makes it harder to fall asleep on Sunday night, which makes Monday morning brutal, which starts the whole cycle again. Sleep researchers sometimes call this “social jet lag,” and it’s a real phenomenon.

A 2019 study published in Sleep Health identified this belief as one of the most problematic sleep myths in terms of public health impact. The experts involved rated it as highly false and highly significant, because it gives people a false sense of control while undermining the consistency their sleep system actually needs.

The more effective approach — and it’s not glamorous — is going to bed and waking up at roughly the same time every day. Including weekends. Your body’s sleep-wake system thrives on regularity. It doesn’t care that it’s Saturday.

Myth 4: If You Have Insomnia, You’re Not Sleeping at All

People with insomnia often describe their experience in absolutes. “I didn’t sleep at all last night.” “I haven’t slept in three days.” And from the inside, it genuinely feels that way.

But here’s what sleep studies consistently show: most people with insomnia are sleeping more than they think. The subjective experience of wakefulness and the objective reality of sleep don’t always line up. This isn’t a character flaw or a failure of perception — it’s a well-documented feature of insomnia called sleep state misperception. Your brain can be in a light stage of sleep while your conscious experience registers it as lying awake.

This doesn’t mean the suffering isn’t real. It absolutely is. When your sleep feels broken, fragmented, or unrefreshing, the daytime impact is the same regardless of what a sleep study might measure. But understanding that you are likely getting some sleep — even when it doesn’t feel like it — can take the edge off the catastrophic thinking that so often accompanies insomnia.

The belief that you’re “not sleeping at all” tends to ratchet up anxiety, which makes falling asleep even harder. It’s another one of those thought patterns that CBT-I works to gently unravel — not by dismissing your experience, but by helping you develop a more accurate picture of what’s actually happening at night.

Myth 5: People With Insomnia Are Sleep Deprived

This one is subtler, and it catches a lot of people off guard. Insomnia and sleep deprivation sound like the same thing, but they’re not — and the distinction matters for treatment.

Sleep deprivation means you’re not getting enough sleep because something external is preventing it. Shift work. A new baby. An exam schedule that has you studying until 2 a.m. Remove the obstacle, and the sleep returns. The underlying system is fine — it just isn’t getting the chance to do its job.

Insomnia is different. With insomnia, you often have plenty of opportunity to sleep. You’re in bed. The lights are off. The house is quiet. And yet your brain won’t cooperate. The system itself has become dysregulated — typically through a combination of conditioned arousal, unhelpful sleep habits, and anxious thinking patterns.

Here’s where it gets interesting: many people with chronic insomnia are actually in a state of hyperarousal, not sleep deprivation. Their nervous systems are running hotter than average, even during the day. This is why some people with insomnia don’t feel sleepy during the day in the way you’d expect someone who “didn’t sleep” to feel. They feel wired, anxious, fatigued — but not necessarily drowsy.

This distinction is more than academic. If you treat insomnia as though it’s just a shortage of sleep, you’ll try to fix it by spending more time in bed. But for someone with insomnia, more time in bed often means more time lying awake, which strengthens the association between bed and wakefulness. It’s exactly the wrong move.

CBT-I therapy works by addressing the actual mechanism — the hyperarousal, the conditioned wakefulness, the catastrophic beliefs about sleep — rather than simply trying to increase hours in bed. It’s why 70 to 80 percent of people who complete CBT-I see meaningful improvement in how they sleep.

So What Actually Helps?

If there’s a thread running through all five of these myths, it’s this: the things that seem like they should help with insomnia — more time in bed, sleeping in on weekends, treating it as a simple stress response — are often the things that make it worse. Insomnia is a condition that thrives on well-intentioned but misguided coping strategies.

The good news is that insomnia is highly treatable. Not with more willpower. Not with more hours in bed. But with a structured, evidence-based approach that changes your relationship with sleep from the inside out.

That’s what CBT-I does. It’s not a quick fix or a one-size-fits-all protocol. It’s a collaborative process — typically six to eight sessions — that retrains your brain and body to sleep the way they were designed to. If you’re curious about what to expect in your first session, or if you’ve been wondering whether therapy is the missing piece in treating your insomnia, those are good places to start.

You don’t have to keep lying awake wondering what you’re doing wrong. Sometimes, the most helpful thing is finding out what you’ve been told that isn’t true.
