There are two ideas about sleep that almost everyone with insomnia believes. Both feel like facts. Both fuel anxiety. And both deserve a serious reality check.

Belief #1: You need 8 hours of sleep

This one is everywhere. Articles, podcasts, well-meaning friends. The message is clear: eight hours or you're damaging yourself.

But it's not true. At least not universally.

The National Sleep Foundation puts average adult sleep needs at 7 to 9 hours, but notes that as few as 6 hours is sufficient for some people.

For those over 65, as few as 5 hours can be appropriate. We all have unique sleep needs, and trying to force yourself into an arbitrary number can actually create the problem you're afraid of.

I've seen people develop insomnia specifically because they tried to make themselves get eight hours when their body didn't need it.

They'd lie in bed for long stretches, awake and increasingly anxious. That planted seeds of doubt about their ability to sleep. The doubt became anxiety. The anxiety became insomnia. All because of a number that didn't apply to them.

Here's a simpler way to think about it. When you come out the other side of insomnia, you'll probably sleep about as much as you used to before it started.

If that's seven hours, great. If it's six and a half, that's fine too. The real test isn't a number on a chart. It's whether you feel reasonably refreshed when you wake up and have decent energy for most of the day.

And notice I said "most of the day." Normal sleepers have energy dips, too. Many don't feel amazing when they first wake up. Almost everyone hits an afternoon slump thanks to circadian rhythms.

After dealing with insomnia for a while, it's easy to develop perfectionistic standards for what good sleep should feel like. But "good sleep" doesn't mean feeling incredible every waking minute. It just means having enough fuel to live your life.

Belief #2: Insomnia is ruining your health

You've probably seen the headlines. Poor sleep linked to heart disease. Sleep deprivation connected to Alzheimer's. The message feels terrifying, and when you're already anxious about sleep, it pours gasoline on the fire.

So let's look at what the research actually says.

A 2018 meta-analysis examined chronic insomnia and mortality across 17 studies, spanning nearly 37 million people tracked for an average of 11.6 years.

The finding: no difference in odds of death for people with insomnia symptoms compared to those without.

Read that again. Across 37 million people over more than a decade, insomnia did not increase the risk of dying.

What about the studies linking poor sleep to diseases like cardiovascular problems or Alzheimer's? Those are correlation studies, and correlation is not causation.

Just because two things occur together doesn't mean one caused the other. It's equally plausible that people with Alzheimer's or heart disease have more trouble sleeping because of those conditions, not the other way around.

On top of that, a lot of sleep research relies on self-reported data (notoriously unreliable), small sample sizes, or statistical thresholds that make the findings hard to replicate.

That doesn't mean sleep research is worthless. But it means the scary headlines deserve a lot more skepticism than most people give them.

There's no final answer on every link between sleep and health. But there is a strong reason to believe it's nowhere near as dire as the headlines suggest.

Why this matters right now

Both of these beliefs, the eight-hour rule and the health panic, do the same thing: they raise the stakes on sleep.

And higher stakes mean more anxiety, which means a more activated nervous system at night, which means worse sleep.

Letting go of these beliefs won't fix your insomnia on its own. But it removes two significant sources of unnecessary fear.

And every layer of fear you peel away brings your nervous system one step closer to the calm it needs to let sleep happen on its own.

You don't need eight hours. Your health is not in danger. You can let those go.
