How sleep typically changes as you age
If you have been wondering, “does sleep change with age,” you are not alone. Many people notice that they fall asleep earlier, wake up more often at night, or feel less rested in the morning as they get older. These changes are very common, and in many cases they are a normal part of aging.
According to MedlinePlus, most older adults have more trouble falling asleep, wake up more often at night, and tend to wake up earlier in the morning than they used to (MedlinePlus). Your total sleep time might stay about the same, around 6.5 to 7 hours, but it is usually more fragmented.
Here are some of the most typical shifts you may notice over the years:
- You feel sleepy earlier in the evening and wake up earlier in the morning
- You wake up 3 to 4 times during the night
- You spend less time in deep, dreamless sleep
- You may feel like you slept poorly, even if you spent enough hours in bed
These changes can be frustrating, especially if you are trying to improve your sleep health. Understanding what is normal and what is not is the first step toward better rest.
How much sleep you still need
It is a common belief that you simply need less sleep as you get older. Research does not support that idea.
The Sleep Foundation notes that adults aged 65 and older should still aim for at least seven hours of sleep each night, just like younger adults (Sleep Foundation). MedlinePlus also states that healthy adults continue to need about 7 to 8 hours of sleep throughout their adult years (MedlinePlus).
What does change is how easy it is to get that sleep. With age you are more likely to:
- Take longer to fall back asleep after waking
- Spend less time in slow wave, or deep, sleep
- Feel tired during the day even if you spent enough total time in bed
So your sleep need does not shrink, but the path to meeting that need often gets bumpier.
What happens to your sleep stages
When you sleep, your brain cycles through different stages. Deep sleep is when your body repairs tissues and supports immune function. Rapid eye movement (REM) sleep is linked with memory and mood.
As you get older, these stages shift:
- Total sleep time tends to decrease from young adulthood to midlife, then levels off after about age 60 (NIH PMC)
- Sleep efficiency, the percentage of time in bed that you actually spend asleep, steadily declines, even after age 60 (NIH PMC)
- You spend less time in slow wave, deep sleep, and more time in lighter stages of sleep (Journal of General and Family Medicine)
Because you are in lighter sleep more often, you wake more easily. Noises, temperature changes, or the need to use the bathroom are more likely to interrupt your rest.
You may not notice a dramatic drop in total hours, especially after age 60, but the quality of those hours can feel different.
Why your internal clock shifts earlier
A big reason sleep changes with age is your circadian rhythm. This is your internal 24 hour clock that tells you when to feel sleepy and when to feel alert.
With age, several things happen:
- The part of the brain that controls this clock, called the suprachiasmatic nucleus, does not work as effectively (Sleep Foundation)
- Your circadian rhythm shifts earlier, a pattern called a “phase advance”
- The daily highs and lows of key signals like melatonin and body temperature become less pronounced (NIH PMC)
In everyday terms, this often looks like:
- Feeling ready for bed much earlier in the evening
- Waking up around 4 or 5 a.m., even if you want to sleep later
- Struggling with shift work or jet lag more than you used to
UCLA Health notes that as adults reach midlife, nightly sleep drops by about 30 minutes every 10 years, mainly because it gets harder to maintain consolidated sleep, not because your body needs less rest (UCLA Health).
How hormones and aging affect your sleep
Several hormones that influence sleep also change with age, and this can disrupt your nights.
Research shows that with aging you often experience:
- Reduced melatonin production, so your “sleep hormone” signal is weaker (Sleep Foundation)
- Lower amplitude of melatonin secretion and altered cortisol rhythms (NIH PMC)
- Declines in sex hormones like testosterone and estrogen, which are linked to changes in sleep quality (NIH PMC)
If you were assigned female at birth, menopause can add extra challenges. Decreases in estrogen and progesterone often bring hot flashes and night sweats, both of which can wake you up repeatedly (UCLA Health).
All of these hormone shifts make sleep lighter and more fragile, which is why sudden awakenings become more common.
Lifestyle changes that influence sleep as you age
Sleep does not change in isolation. Your daily habits, your environment, and your health all matter, and many of these naturally shift with age.
Common lifestyle changes that can affect your sleep include:
- Less physical activity due to retirement, joint issues, or mobility limits
- Fewer social interactions, which can lower mood and disrupt routines
- Less time outdoors and less exposure to daylight, especially if you no longer commute or spend time outside for work (Sleep Foundation)
Older adults generally get only about an hour of daylight exposure per day, on average, and this reduced light input makes it harder for the brain clock to stay in sync (Sleep Foundation). This is especially true if you live in a care facility or have a condition like Alzheimer’s disease.
You might also find that:
- You nap more frequently during the day
- You spend more total time in bed even though you are not sleeping the whole time
- Your schedule is looser, so bedtimes and wake times drift
All of these can feed into more fragmented nighttime sleep.
Common sleep problems in older adults
Sleep difficulties become more frequent with age, but they are not something you simply have to put up with.
According to the Sleep Foundation, between 40 percent and 70 percent of older adults live with chronic sleep issues, and up to half of these problems may not be diagnosed (Sleep Foundation). MedlinePlus notes that disruptions can include trouble falling asleep, trouble staying asleep, excessive sleep, or unusual behaviors during sleep (MedlinePlus).
Some common patterns include:
- Sleep maintenance insomnia: You fall asleep fairly easily but wake up often and have trouble staying asleep
- Early morning awakenings: You wake up very early and cannot fall back asleep, even when you still feel tired
- Increased daytime sleepiness: You feel drowsy or need multiple naps to get through the day
Research suggests that in older adults, sleep maintenance insomnia and early awakenings are more frequent than problems falling asleep in the first place (Journal of General and Family Medicine).
At the same time, older adults are sometimes less likely to mention sleep problems to a doctor, perhaps because they accept poor sleep as a normal part of aging or have become used to feeling tired (Journal of General and Family Medicine).
How sleep difficulties affect your health
Even if you tell yourself you are just a “light sleeper now,” consistently poor sleep can take a toll on your health and daily life.
MedlinePlus notes that chronic insomnia in older adults can lead to:
- Confusion and mental changes
- Mood changes, including depression
- Increased risk of automobile accidents (MedlinePlus)
Sleep fragmentation and low oxygen levels during sleep have also been linked to poorer physical function, such as weaker grip strength and slower walking speed, in older adults (Journal of General and Family Medicine).
If you regularly wake unrefreshed, feel foggy, or rely heavily on caffeine to function, it is worth treating your sleep as a key part of your health, not just an annoyance.
When changing sleep is normal, and when to get help
Some sleep changes are expected as you age. Others are signs that something more is going on.
Changes that are usually normal
These patterns often reflect typical aging, especially if they are mild:
- Falling asleep and waking up earlier than you did in your 20s or 30s
- Waking up a few times each night but falling back asleep fairly easily
- Sleeping a bit less deeply than you once did
If you still feel mostly rested, function well during the day, and do not feel overly sleepy, you may simply be adjusting to a new sleep pattern.
Changes that deserve medical attention
It is a good idea to talk to a healthcare provider if you notice:
- Persistent trouble falling asleep or staying asleep at least three nights a week
- Loud snoring, gasping, or choking during sleep, as reported by a partner
- Feeling very sleepy during the day or frequently nodding off
- Mood changes, confusion, or memory problems that seem linked to poor sleep
- Pain, frequent urination, or breathing problems that repeatedly wake you up
Sleep disorders become more common with age, and conditions such as dementia and Parkinson’s disease can significantly change sleep patterns (UCLA Health). The good news is that treating underlying issues, like chronic pain, depression, or nocturia, often improves sleep quality (MedlinePlus).
Why being cautious with sleep medications matters
It can be tempting to solve sleep problems with a pill, especially when you feel desperate for rest. However, older adults respond to sleep medications differently than younger adults, and side effects can be more serious.
MedlinePlus notes that because of these differences, it is important to consult a healthcare provider before using any sleep aid (MedlinePlus). Sedative medications can:
- Increase your risk of falls and fractures
- Cause confusion or daytime drowsiness
- Interact with other medications you may be taking
Safer approaches often include:
- Cognitive behavioral therapy for insomnia (CBT I)
- Melatonin supplements in appropriate doses and timing, under medical guidance
- Lifestyle adjustments like consistent routines and better light exposure (MedlinePlus)
If you already use sleeping pills regularly, it is worth asking your healthcare provider if there are non drug strategies that could work as well or better for you.
Habits that support better sleep as you age
You cannot stop the clock, but you can create conditions that help your aging body sleep as well as possible. Small, consistent changes add up.
Here are practical strategies based on the research:
Strengthen your daytime routine
- Get more daylight: Aim for regular outdoor time, especially in the morning, to help keep your circadian rhythm on track (Sleep Foundation). Even a daily walk around the block helps.
- Move your body: Gentle exercise like walking, stretching, or water aerobics during the day can make it easier to fall asleep at night.
- Limit long naps: Short naps of 20 to 30 minutes can be refreshing, but long or late afternoon naps may cut into your nighttime sleep.
Make your evenings more sleep friendly
- Set a steady schedule: Go to bed and wake up at about the same time every day, including weekends.
- Create a calming routine: Read, listen to soft music, or practice relaxation techniques to signal to your body that it is time to wind down (MedlinePlus).
- Watch your light exposure: Dim bright overhead lights in the evening and limit bright screens close to bedtime when possible.
Improve your sleep environment
MedlinePlus recommends basic but powerful steps such as keeping your bedroom comfortable and quiet (MedlinePlus).
You can try:
- Keeping the room cool enough for comfort
- Using blackout curtains or an eye mask if early light wakes you
- Trying a fan or white noise if sounds disturb you
- Choosing a mattress and pillows that support your preferred sleep position
Adjust how you respond to wake ups
If you wake during the night and cannot fall back asleep:
- Avoid lying awake in bed for long stretches
- Get up, sit in low light, and do something relaxing, like reading
- Return to bed when you feel sleepy again
This helps your brain keep associating your bed with sleeping rather than with worrying or clock watching (MedlinePlus).
Key takeaways
When you ask, “does sleep change with age,” the answer is yes, it usually does. You are likely to:
- Need just as much sleep as before, at least 7 hours per night, even though it becomes harder to get
- Spend less time in deep sleep and more time in lighter stages
- Wake up more often during the night and earlier in the morning
- Experience changes in hormones, circadian rhythm, and lifestyle that all affect your rest
Some of this is a normal part of getting older. However, frequent sleep problems are not something you have to accept.
If you feel that poor sleep is affecting your mood, thinking, or daily life, reach out to a healthcare provider. Addressing medical issues, reviewing medications, and improving sleep habits can make your nights more restorative again, no matter your age.
