For most adults, a normal sleeping heart rate sits somewhere between 60 and 73 beats per minute.
But the surprising finding after analysing 537,000 nights of Ultrahuman Ring data is that this figure doesn’t meaningfully change as you get older.
The average 25-year-old and 65-year-old are within 2 bpm of each other. While sleep architecture changes substantially as we age, our resting heart rates stay the same.
In this guide, we explain what counts as normal at your age – and the science behind what happens to your heart rate while you sleep.

Key takeaways
- The typical sleeping heart rate is 64 to 67 bpm at every age decade.
- Sleeping heart rate is your average heart rate across your night.
- Most adults cluster tightly, inside a 10 to 13 bpm window, whatever their age.
- Sleeping heart rate is different from resting heart rate – and on average Ultrahuman Ring users’ RHR was 10bpm lower.
Normal sleeping heart rate by age
| Age | Typical sleeping heart rate | Most people fall between |
|---|---|---|
| 18–29 | 66 bpm | 60–73 |
| 30–39 | 67 bpm | 60–73 |
| 40–49 | 66 bpm | 60–73 |
| 50–59 | 66 bpm | 60–73 |
| 60–69 | 65 bpm | 59–72 |
| 70+ | 64 bpm | 59–71 |
These figures come from 78.3 million nights of sleep recorded by 532,195 Ultrahuman Ring users between June 2024 and May 2026.
The widespread assumption that sleeping heart rate climbs steadily with age does not appear in them at all. If anything, it drifts down slightly after 60.
People also cluster more tightly than you would expect. The middle half of users falls inside roughly the same 10 to 13 beat window at every age, so there is no separate normal to grow into.
Is my sleeping heart rate normal?
If you are inside the band for your age, clearly yes. But even if you sit outside it, it doesn’t mean anything is wrong.
Well-trained endurance athletes sit far below these ranges, often in the 40s or below. That is a strong heart moving more blood per beat, and on its own it is not a concern.
Sitting significantly higher than your age bracket is worth more attention.
But the most important comparison is against yourself. A sustained, unexplained 10 bpm rise above your usual means considerably more. Using a device to track your heart rate and have awareness of your own normal is where the real value of wearables lie.
Resting heart rate vs sleeping heart rate
This trips up almost everyone, and most articles on the subject have it backwards.
Sleeping heart rate is the average across the whole night. Across Ultrahuman members that runs about 67 bpm.
Resting heart rate, the figure your Ring shows you, is the lowest point your heart reached during that same night. Across the same members it runs about 57 bpm.
The two sit around 10 beats apart and rise and fall almost in step. Neither is more correct, but they are not interchangeable, and checking your resting number against a sleeping chart will tell you that you are doing better than you are.
Most health writing defines resting heart rate as something you measure awake, before getting out of bed. The Ring does not do it that way, which is why its number looks low next to the tables you will find elsewhere.
Why your heart slows at night
The parasympathetic nervous system, the rest-and-digest side, takes over as you fall asleep. It slows the heart and drops blood pressure.
It is not steady through the night. Heart rate reaches its lowest in deep non-REM sleep, which is concentrated in the first half. REM sleep pushes it back up in short bursts, sometimes close to daytime levels.
The lowest point of all usually lands in the early hours, around three to five in the morning, where the deepest parasympathetic phase and your natural circadian trough overlap.
What pushes your sleeping heart rate up
Alcohol is the clearest single-night cause, and the one we can measure directly because members tag it themselves. Comparing 5,129 members against their own non-drinking nights, across 29,826 tagged nights, sleeping heart rate ran a median 4.3 bpm higher on nights they logged a drink.
A late hard session raises it the same night, especially in the evening. Over months the same training lowers your baseline, so the short-term cost and the long-term gain point in opposite directions.
A warm bedroom is common and easy to miss, because nothing about it feels like a cause.
A heavy or late meal keeps digestion running into the night.
Stress shows up the same night after an acute one, and drifts the baseline upward over weeks when it does not let go.
Being run down. When you are coming down with something your heart usually runs faster at night, which is worth noticing when nothing else explains it. A single raised night on its own means very little.
The luteal phase. In menstruating members, sleeping heart rate typically rises in the two weeks before a period and settles again as it starts.
Frequently asked questions
What is a normal sleeping heart rate by age?
The typical figure runs 64 to 67 bpm at every age decade, with most adults between about 59 and 73. Your own baseline matters more than the band you fall into.
Is sleeping heart rate the same as resting heart rate?
No. Sleeping heart rate is the average across the night, around 67 bpm. Your Ring’s resting heart rate is the lowest point of that same night, around 57. They move together, but they are not the same number.
Why does my heart rate drop while I sleep?
The parasympathetic nervous system takes over, slowing the heart and lowering blood pressure. The deepest dip comes in non-REM sleep in the early hours. REM sleep pulls the average back up in short bursts.
Does alcohol affect sleeping heart rate?
Yes. Across 5,129 members compared against their own non-drinking nights, sleeping heart rate ran a median 4.3 bpm higher on nights they logged a drink.
What’s a dangerously high sleeping heart rate?
No single number makes one dangerous, which is why the question worth asking is how far yours sits from your own usual. A sustained rise of around 10 bpm above your baseline, lasting more than a week with nothing to explain it, is worth raising with a doctor. So is a reading that stays above 80 to 90 bpm for several weeks in an otherwise healthy adult. A raised number alongside chest discomfort, breathlessness, fainting or new palpitations should be looked at the same day.
