New research suggests that when you sleep may matter more than many of us realize. Here’s what the science actually says—and what you can do about it.
By Tom Green | Well After 50
Most of us have heard that we need seven or eight hours of sleep. We’ve heard it from doctors, read it in magazines, and probably told ourselves a hundred times that we ought to get to bed earlier.
But here’s something I found interesting: What if getting enough sleep is only part of the picture? What if keeping a regular sleep schedule matters, too?
Researchers studying thousands of adults have found a connection between irregular sleep patterns and a higher risk of dying earlier. That certainly caught my attention.
Before anybody starts worrying about staying up late on Saturday night, though, there’s something important to understand. These studies show an association. They don’t prove that going to bed at the same time every night will make you live longer.
Still, the findings are worth looking at, especially for those of us over 50.
The short answer
In a study of about 61,000 adults with an average age of 63, people with the most regular sleep schedules had a 20% to 48% lower risk of dying during the study than people with the most irregular schedules. It doesn’t prove cause and effect, but it’s a strong hint that when you sleep matters, not just how long.
The simplest thing you can do tonight: pick a wake-up time and stick to it every day, weekends included. Your bedtime will start to follow.
What Researchers Discovered About Sleep and Longevity
A study published in the journal SLEEP examined sleep patterns in 60,977 UK Biobank participants, whose average age was approximately 63. Instead of simply asking people how long they slept, researchers used wearable devices to measure their sleep and activity patterns.
They were interested in something called sleep regularity—how consistently someone was asleep or awake at similar times from one day to the next.
Over an average follow-up of about 6.3 years, researchers found that participants in the four groups with more regular sleep patterns had a 20% to 48% lower risk of death from any cause, compared with those in the least regular group.
Perhaps the most surprising finding was that sleep regularity predicted mortality risk more strongly than sleep duration in the researchers’ models. That’s not the same as saying sleep duration doesn’t matter. It absolutely does. But it suggests we’ve been overlooking an important part of healthy sleep.

Another Large Study Found a Similar Connection
A separate study published in eLife examined 88,975 UK Biobank participants, with an average age of about 62. Researchers again used activity-monitoring devices to examine sleep regularity.
They found that people with highly irregular sleep patterns had higher mortality risks than those with more consistent patterns. In one comparison, participants near the low end of the sleep-regularity scale had a 53% higher estimated mortality hazard than those around the middle of the scale, after adjustments for other factors.
These findings weren’t based on somebody remembering how much they slept last Tuesday. They came from objective recordings. That’s valuable, although wearable measurements and statistical adjustments still can’t eliminate every possible source of error.
The two studies also drew on the UK Biobank, so they shouldn’t be treated as two completely independent populations.

What a 2025 Review Added to the Picture
By 2025, there was enough research on sleep regularity for scientists to examine the findings across many different studies. A systematic review published in Sleep Medicine Reviews included 59 primary studies.
The researchers found that irregular sleep timing was associated with several health concerns, including higher blood pressure, insulin resistance, cardiovascular events, and symptoms of depression and anxiety. Five of the reviewed cohorts also linked less regular sleep with higher all-cause mortality.
The review strengthens the argument that sleep regularity deserves attention alongside sleep duration and quality. But the authors also called for further intervention research. That’s important because we still need stronger evidence about whether deliberately improving sleep regularity lowers the risk of disease or premature death.

Why Might Your Sleep Schedule Matter?
Our bodies run on an internal timing system commonly called the circadian rhythm. It’s involved in much more than deciding when we feel sleepy. This system helps coordinate hormone activity, body temperature, alertness, and other biological functions throughout the day and night.
Light exposure, mealtimes, physical activity, and sleep schedules all interact with this internal clock. When bedtime and waking time shift considerably from one day to another, the body’s timing signals may become less consistent.
Researchers are investigating whether this kind of disruption contributes to metabolic changes, inflammation, and cardiovascular problems. However, that doesn’t mean an irregular schedule automatically causes these conditions. Health problems, work schedules, stress, medications, and other circumstances can also disrupt sleep. The relationship may work in more than one direction.
Does Sleep Change After 50?
Yes, and that’s something many of us recognize without needing a scientific study to tell us. You might fall asleep earlier than you used to, wake during the night, or find yourself wide awake before sunrise.
Pain, medications, bathroom trips, stress, and sleep disorders can make matters worse. But needing less sleep simply because we’re getting older is a common misconception.
According to the CDC, adults ages 61–64 generally need 7–9 hours, while adults 65 and older are advised to get 7–8 hours per night. And those hours need to be reasonably restorative.
If you’re spending eight hours in bed but waking repeatedly and feeling exhausted the next day, it’s worth finding out why. That’s particularly important when poor sleep has become something you’ve simply learned to live with.
Seven Ways to Build a More Consistent Sleep Routine After 50
You don’t have to buy expensive gadgets, track every minute of sleep, or build your entire evening around a complicated routine. Start with a few manageable habits.
1. Give Yourself a Regular Wake-Up Time
If you change only one part of your sleep schedule, a consistent wake-up time is a practical place to begin. Try getting up around the same time each morning, including weekends. You don’t need to panic about an occasional late morning. The goal is a pattern your body can become accustomed to.
2. Get Some Daylight Early in the Day
Morning daylight helps your internal clock distinguish daytime from nighttime. If you’re able, spend some time outdoors after getting up. Even a morning walk or sitting outside with your coffee can help establish a routine. And you don’t have to turn it into a workout.
3. Watch That Afternoon Coffee
Here’s one that can sneak up on us. You may enjoy an afternoon cup of coffee and never feel especially stimulated by it. But caffeine can remain active in the body for hours. If you’re having trouble falling asleep, try moving your last caffeinated drink earlier and see whether your sleep improves.
4. Keep Moving During the Day
Regular physical activity supports better sleep and overall health. Walking, gardening, swimming, or strength training can all fit into a healthy routine. If evening exercise leaves you wide awake, try doing it earlier. And if pain is interfering with your sleep, choose activities that don’t aggravate it.
5. Make Your Bedroom Work for You
A dark, quiet, comfortable room can make sleeping easier. Keep the temperature comfortable, reduce unnecessary light, and limit distractions. If television or phone use keeps you awake longer than intended, try putting those aside during your wind-down period.
6. Pay Attention to Alcohol and Late Meals
Alcohol may make you sleepy initially, but it can also disrupt sleep later in the night. Heavy meals close to bedtime may cause discomfort, especially if you experience acid reflux. You don’t need a rigid set of rules for every evening. Pay attention to what seems to disturb your sleep and make adjustments where you can.
7. Don’t Ignore Persistent Sleep Problems
This might be the most important point in the entire article. If you’re regularly struggling to sleep, waking up gasping, snoring heavily, or feeling unusually sleepy during the day, don’t assume it’s just part of getting older.
Sleep apnea and chronic insomnia are health problems that deserve proper evaluation. For persistent insomnia, cognitive behavioral therapy for insomnia (CBT-I) is recommended as a first-line treatment by the American College of Physicians. There’s a difference between improving your sleep habits and trying to treat a medical sleep disorder on your own.
A Simple 7-Day Sleep Schedule Reset
Want to try this without overthinking it? Here’s a one-week plan I’d follow:
- Day 1: Choose your wake-up time, one you can keep every day of the week. Set an alarm.
- Day 2: Get outside, or sit by a bright window, within an hour of waking. Even 10 minutes helps set your body clock.
- Day 3: Make 2 p.m. your coffee cutoff.
- Day 4: Take a walk sometime during the day. Moving in daylight helps you sleep at night.
- Day 5: Start a 30-minute wind-down before bed: dim lights, screens down, something calm.
- Day 6: Keep your wake-up time even though it’s the weekend. This is the hard one, and the one that matters most.
- Day 7: Notice how you feel. Most people find they get sleepy at about the same time each night once the wake-up time is steady.
What If You Wake Up at 3 A.M. Every Night?
First, don’t assume you’ve ruined your night’s sleep. An occasional awakening doesn’t mean something is seriously wrong. If you wake up and can’t get back to sleep, try to avoid watching the clock and becoming frustrated about how many hours you have left.
When you’re lying awake for a long time, getting out of bed briefly for a quiet, relaxing activity may be more helpful than continuing to struggle. If this happens frequently, a sleep diary can help you notice patterns.
Write down your bedtime, wake-up time, nighttime awakenings, caffeine use, and how rested you feel. Bring that information to your healthcare provider if the problem persists. You may discover that stress, pain, medication timing, or another treatable issue is affecting your rest.
Can Better Sleep Actually Help You Live Longer?
Here’s where I think we need to be careful. The research gives us good reason to take regular sleep seriously. But we cannot honestly say that setting an alarm for the same time every morning will add five years to your life. The studies don’t establish that.
What they do suggest is that sleep regularity is an important part of overall sleep health—and one that’s easy to overlook. We already have strong reasons to care about getting enough good-quality sleep. Poor sleep is linked with cardiovascular and metabolic health problems, and it can affect how we feel and function during the day.
Building a steadier routine is a reasonable step toward better sleep, even though its effect on lifespan hasn’t been proven.

Common Questions
How many hours of sleep do you need after 60?
The CDC recommends 7 to 9 hours for adults 61 to 64, and 7 to 8 hours for adults 65 and older. Quality and regularity matter too.
Is it bad to sleep in on weekends?
An occasional lie-in won’t hurt, but regularly shifting your schedule by a couple of hours can leave you feeling like you have jet lag on Monday. A steady wake-up time is the most helpful habit.
What is the best bedtime after 50?
There isn’t one perfect time. The best bedtime is one you can keep consistently that still gives you 7 or more hours before your wake-up time.
Are naps okay after 50?
A short nap of 20 to 30 minutes in the early afternoon is fine for most people. Long or late naps can make it harder to fall asleep at night.
Why do I wake up so early now?
Our body clock tends to shift earlier as we age, so many people feel sleepy earlier and wake earlier. If you’re waking too early and can’t get back to sleep, morning light and a consistent schedule can help, and it’s worth mentioning to your doctor.
My Take: Don’t Turn Sleep Into Another Thing to Worry About
One thing I’ve learned about getting older is that there always seems to be another health rule we’re supposed to follow. Eat this. Don’t eat that. Exercise more. Avoid stress. Get eight hours of sleep. Sometimes it can feel exhausting just trying to do everything right.
I don’t think that’s the lesson here. The lesson is that something as ordinary as our daily sleep routine deserves a little more attention.
If you’re sleeping well, feeling rested, and keeping a fairly steady schedule, that’s encouraging. If you’re struggling, maybe start by making one small change instead of trying to fix everything at once.
And remember, healthy aging isn’t about being perfect. It’s about making choices that give us a better chance of feeling good and staying active in the years ahead. That’s something worth getting a good night’s sleep for.
