Are You Getting Quality Sleep?

The Overlooked Heart Prescription

A couple of years ago, I asked a simple question:

Are you getting quality sleep?

Today, I want to revisit that question—but this time through the lens of your heart and metabolic health.

Most of us think of sleep as downtime. Something we do when the day is finally over.

But while you're sleeping, your body isn't simply shutting down.

It's restoring, regulating and resetting.

And your heart is very much part of that conversation.

THE BIG IDEA

Sleep is so important to cardiovascular health that the American Heart Association includes it in Life's Essential 8, alongside nutrition, physical activity, blood pressure, cholesterol and blood sugar.

For most adults, the goal is an average of 7–9 hours each night.

But here's what I really want you to understand:

Healthy sleep is about more than the number of hours you spend in bed.

Quality. Regularity. Timing. Continuity. And how you function during the day.

These are all pieces of what experts now describe as multidimensional sleep health.

You can spend eight hours in bed and still wake up exhausted.

That's worth paying attention to.

CONNECT THE DOTS

Think about it this way:

SLEEP → METABOLISM → BLOOD PRESSURE → INFLAMMATION → ❤️ HEART

Poor sleep is associated with several of the same cardiometabolic factors we've been discussing throughout this series—including higher blood pressure, impaired glucose regulation, abnormal lipids, obesity and inflammatory signaling.

And remember our conversations about metabolism and food?

There's another connection.

Your body has an internal clock—your circadian rhythm—that helps coordinate sleep and wakefulness as well as hormone release, digestion, metabolism and cardiovascular function.

Irregular sleep schedules and disruption of that natural rhythm have been associated with obesity, type 2 diabetes, hypertension and cardiovascular disease.

Your body doesn't just pay attention to how long you sleep.

It also pays attention to rhythm.

DR. G'S TAKE

When I ask someone about sleep, I don't want to hear only:

“I get seven hours.”

I also want to know:

Do you wake refreshed?

Are you waking repeatedly during the night?

Do you snore loudly?

Has anyone noticed pauses in your breathing?

Are you struggling with daytime sleepiness?

Does your sleep schedule change dramatically from day to day?

Because sometimes what looks like “I'm just not sleeping well” deserves a closer look.

Persistent snoring, witnessed breathing pauses, disrupted sleep or excessive daytime sleepiness may warrant evaluation for an underlying sleep disorder rather than simply being accepted as part of stress—or getting older.

TRY THIS THIS WEEK

Don't try to create the perfect bedtime routine overnight.

Choose one sleep anchor.

Maybe it's:

⏰ Set it: Keep your bedtime and wake time reasonably consistent.

📱 Dim it: Reduce bright light and screens as bedtime approaches.

🌙 Create it: Give yourself a short, predictable wind-down routine.

🛏️ Protect it: Keep your bedroom dark, quiet and comfortable.

Or perhaps your next step is finally talking with your healthcare professional about persistent snoring, breathing pauses, insomnia or daytime sleepiness.

One change. Repeated consistently.

Your body loves rhythm.

❤️ ONE-MINUTE HEART CHECK

Tonight, ask yourself:

Am I usually getting 7–9 hours?

Do I wake feeling restored?

Is my sleep schedule reasonably consistent?

Am I frequently waking during the night?

Do I snore heavily or struggle with daytime sleepiness?

Don't judge the answers.

Notice them.

Sometimes awareness is the first clue that something deserves attention.

THE BRIDGE FORWARD

Over the past several weeks, we've connected a lot of dots:

Autoimmunity.

Inflammation.

Cholesterol.

Metabolism.

Food.

And now—

Sleep.

Sleep isn't wasted time.

It isn't simply what happens after everything else on your to-do list is finished.

Sleep is part of your cardiovascular prevention plan.

So tonight, instead of thinking only about getting through another busy day, consider giving your body something it needs just as much as movement and good nutrition:
