HEART RATE: What your resting Heart Rate is telling you

A pro marathoner and someone who never exercises can have the same resting heart rate. So what makes the athlete’s heart better?

It pumps more blood with each beat. More force per squeeze = fewer beats needed. That’s efficiency.

Most people have no clue what their resting heart rate is. Maybe they saw it once on a watch. But they’ve never asked: Is mine good? What’s it saying?

That’s a miss. Because this one number tells you a lot, with almost no effort.

It’s how many times your heart beats per minute when you’re awake, calm, and sitting still.

Normal = 60–100 bpm. But within “normal,” lower is usually better.

• 40s–50s: Often means a strong, efficient heart. It moves enough blood without working hard.
• 80s–90s: Your heart’s working overtime just to keep you idling.

Think of a car at a stoplight. A good engine idles low and quiet. A strained engine idles high and loud.

Over a lifetime, a heart at 80 bpm beats tens of millions more times than one at 50 bpm. That adds up.

If your resting heart rate climbs, it’s usually for a reason:

1. You’re out of shape - Most common cause. An unfit heart works harder. Good news: this is fixable.
2. Chronic stress - Stress hormones keep your heart rate up. A high resting rate can be the first sign your nervous system’s been in overdrive.
3. Poor sleep - One bad night spikes it. Months of bad sleep keeps it high.
4. Dehydration, alcohol, caffeine - All make your heart work harder. Alcohol especially raises it for hours — even into the next morning.
5. Medical issues/meds - Thyroid problems, anemia, infections, or certain prescriptions. A sudden jump? Talk to your doctor.

One reading tells you a little. The trend over weeks and months tells you everything.

• Creeping up over a year? Could be weight gain, stress, worse sleep, or declining fitness.
• Drifting down? Your workouts and sleep are working.

That’s the real power of your watch: not today’s number, but the line it draws over time.

A 5–10 beat jump that stays high is often your body’s first warning sign — before you even feel sick, overtrained, or burnt out.

Best time: First thing in the morning, before you get up or have coffee.

1. Use your watch/ring - Most track it automatically while you sleep.
2. Do it manually - Lie still. Find your pulse on your wrist or neck. Count beats for 30 seconds × 2.

Check a few mornings and average it. One weird night can throw it off. Your average = your baseline. That’s the number to watch.

Resting heart rate responds fast. Most people can drop it in a few months:

1. Move more - Walking, cycling, swimming, jogging. Aerobic exercise = stronger heart = fewer beats needed. Most effective step.
2. Protect sleep - Consistent, quality sleep lets your nervous system recover and your rate settle.
3. Manage stress - 5 minutes of slow breathing helps now and long term.
4. Hydrate + limit alcohol - Both make a difference faster than you’d think.

No gym or complex plan needed. Just consistency. Your resting heart rate will keep score — and show progress before the mirror does.

Your heart beats ∼100,000 times a day whether you notice or not.

Taking 30 seconds to check in might be the easiest health habit you ever build.
