A resting pulse of 64 beats per minute is good. It falls within the normal adult range of 60 to 100 bpm and sits toward the lower, healthier end of that spectrum. The American Heart Association puts it simply: when it comes to resting heart rate, lower is better.
Why 64 BPM Is Better Than “Normal”
While any resting heart rate between 60 and 100 is technically normal, not all numbers in that range carry the same health outlook. A 2013 study published in the journal Heart followed about 3,000 men for 16 years and found that rates near the top of the normal range were linked to higher blood pressure, greater body weight, and elevated blood fats. The risk climbed steeply: a resting heart rate between 81 and 90 doubled the chance of premature death, and rates above 90 tripled it.
At 64, your heart is pumping efficiently enough that it doesn’t need to work as hard between beats. That generally reflects good cardiovascular fitness and is associated with reduced rates of cardiac events like heart attacks. Highly trained athletes can have resting rates as low as 40 bpm, so 64 puts you in solid territory between average and athletic.
What Your Resting Heart Rate Reflects
Your resting heart rate is essentially a measure of how efficiently your heart pumps blood. A stronger heart pushes more blood with each beat, so it needs fewer beats per minute to keep up with your body’s demands. That’s why regular aerobic exercise tends to pull your resting rate down over time.
Several factors beyond fitness can shift your number up or down on any given day:
- Medications: Blood pressure drugs (beta-blockers, calcium channel blockers), certain antidepressants, and heart rhythm medications can all lower your pulse into the 50s or 60s.
- Caffeine and stimulants: These push your rate higher temporarily.
- Stress and sleep: Poor sleep or chronic stress raises your baseline. Your heart rate naturally drops during sleep and is lowest first thing in the morning.
- Thyroid function: An underactive thyroid can slow your heart rate, while an overactive one speeds it up.
- Hydration and temperature: Dehydration and heat both force your heart to beat faster to maintain blood flow.
How to Get an Accurate Reading
The number you see matters less if you’re not measuring it correctly. Your true resting heart rate is best captured after you’ve been sitting or lying still for at least five minutes, ideally in the morning before coffee or exercise. Place two fingers on the inside of your wrist, just below the base of your thumb, and count beats for 30 seconds, then double it. Many smartwatches and fitness trackers do this automatically, though wrist-based sensors can be off by a few beats depending on fit and movement.
If you’re checking because a device gave you a reading of 64 during the day while you were moving around, your actual resting rate is likely a bit lower. Activity, even walking across the room, nudges the number up.
When a Low Pulse Is a Problem
A heart rate of 64 is not low enough to raise concern. Bradycardia, the medical term for a slow heart rate, is defined as fewer than 60 beats per minute, and even then it’s only a problem if the heart can’t pump enough oxygen-rich blood to the body. Rates between 40 and 60 are common in fit young adults and during sleep.
Bradycardia becomes concerning when it causes symptoms: dizziness, unusual fatigue (especially during physical activity), shortness of breath, confusion, fainting, or chest pain. If your pulse drops below 60 and you feel fine, there’s generally nothing to worry about. If you experience any of those symptoms alongside a slow pulse, that’s worth a medical conversation.
Tracking Changes Over Time
A single reading of 64 is reassuring, but the real value of knowing your resting heart rate comes from watching it over weeks and months. A gradual decrease usually signals improving cardiovascular fitness. A sudden or sustained increase of 10 or more beats from your baseline, without an obvious cause like illness or stress, can be an early signal that something has changed in your health.
If you’re using your resting heart rate as a fitness benchmark, checking it first thing in the morning two or three times a week gives you a reliable trend line. At 64 bpm, you’re starting from a healthy place.
