In your younger years, you may have slept soundly through the night, waking refreshed in the morning. But as the years pass, many people notice changes. It may take longer to fall asleep. You wake more often during the night. You feel sleepy earlier in the evening and wake before dawn, unable to drift off again.
Changes in sleep are very common with age, but poor sleep is not something you simply have to accept. Understanding why sleep changes can help you make adjustments that lead to better rest. This article explains how sleep changes as we age, common causes of poor sleep in later life, and practical ways to sleep better.
How Sleep Naturally Changes With Age
Less Deep Sleep
Deep sleep, also called slow-wave sleep, is the most restorative stage. It decreases gradually from early adulthood onward. Older adults typically spend much less time in deep sleep than younger people, which can make sleep feel lighter and less refreshing.
More Night Waking
With lighter sleep, it's easier to be woken by noise, discomfort, or the need to use the bathroom. Older adults tend to wake more often during the night.
An Earlier Body Clock
The body's internal clock tends to shift earlier with age. Many older adults feel sleepy earlier in the evening and wake earlier in the morning. This is called an advanced sleep phase.
Changes in Melatonin
Some research suggests the body may produce less melatonin, the hormone that helps signal sleep, as we age, although this varies between individuals.
More Daytime Napping
Lighter nighttime sleep may lead to more daytime naps, which can in turn make nighttime sleep harder.
Despite these changes, older adults still need about seven to eight hours of sleep. The ability to sleep may change, but the need for sleep does not drop dramatically.
Common Causes of Poor Sleep in Later Life
Health Conditions
Many conditions that become more common with age can disrupt sleep, including arthritis and chronic pain, heart and lung conditions, acid reflux, diabetes, and prostate problems.
Nighttime Urination
Needing to urinate during the night becomes more common with age and is a frequent cause of sleep disruption.
Sleep Apnea
Obstructive sleep apnea, where breathing repeatedly stops and starts during sleep, becomes more common with age. It causes fragmented sleep, loud snoring, and daytime tiredness, and is linked with heart problems and cognitive decline if untreated.
Restless Legs Syndrome
An uncomfortable urge to move the legs, often worse in the evening, can make it hard to fall asleep.
Medications
Some medications, including certain blood pressure drugs, antidepressants, steroids, and diuretics, can affect sleep.
Mood and Life Changes
Retirement, loss of loved ones, loneliness, anxiety, and depression can all affect sleep.
Less Daylight and Activity
Spending more time indoors and being less active can weaken the body clock's signals, leading to poorer sleep.
Menopause
Hot flashes and night sweats can disrupt sleep for many women in midlife.
Why Good Sleep Matters for the Aging Brain
Sleep is crucial for memory, mood, and brain health. Research suggests that the brain's waste-clearing system works more actively during sleep, helping remove proteins associated with Alzheimer's disease. Studies have also linked poor sleep and short sleep in midlife and later life with a higher risk of cognitive decline. Improving sleep is one of the most valuable things you can do for your brain as you age.
How to Sleep Better as You Get Older
Keep a Regular Schedule
Go to bed and wake up at the same times each day, including weekends.
Get Morning Light
Bright daylight in the morning strengthens your body clock. If you tend to get sleepy too early in the evening, getting more light in the late afternoon or early evening may help shift your clock later.
Stay Active
Regular physical activity improves sleep quality. Walking, swimming, tai chi, and gardening are all great options. Try to finish vigorous exercise a few hours before bed.
Limit Naps
If you nap, keep it short, around 20 to 30 minutes, and early in the afternoon.
Watch Evening Drinks
Limit fluids in the two hours before bed to reduce nighttime bathroom trips. Avoid caffeine after early afternoon and limit alcohol, which disrupts sleep.
Create a Restful Bedroom
Keep your bedroom cool, dark, and quiet. Consider blackout curtains, earplugs, or a white noise machine. Make sure your mattress and pillows are comfortable.
Wind Down
Develop a relaxing routine before bed: reading, gentle stretching, a warm bath, or calming music. Avoid screens and stimulating activities.
Stay Engaged During the Day
An active, engaging day helps you sleep better at night. Social activities, hobbies, learning, puzzles, and brain games keep the mind stimulated and build healthy sleep pressure.
Manage Worries
Write down worries or tomorrow's plans earlier in the evening. Practice relaxation techniques like slow breathing or mindfulness.
Get Out of Bed If You Can't Sleep
If you're awake for more than 20 minutes, get up and do something quiet in dim light until you feel sleepy.
Be Cautious With Sleeping Pills
Many sleeping pills and over-the-counter sleep aids can cause next-day grogginess, confusion, and falls in older adults. Some, such as those containing diphenhydramine, have anticholinergic effects linked with memory problems. Talk to your doctor before using sleep medications.
Cognitive Behavioral Therapy for Insomnia
Cognitive behavioral therapy for insomnia (CBT-I) is the recommended first-line treatment for chronic insomnia, including in older adults. It helps change habits and thoughts that interfere with sleep and has lasting benefits without the side effects of medication.
When to See a Doctor
- You regularly have trouble falling or staying asleep
- You snore loudly or stop breathing during sleep
- You feel very sleepy during the day
- You wake frequently to urinate
- Pain or restless legs disturb your sleep
- Your mood is low or you feel anxious
Keep a Sleep Diary
A sleep diary can reveal patterns you might otherwise miss. For two weeks, note when you go to bed, roughly how long it takes to fall asleep, how often you wake, when you get up, any naps, and what you ate and drank in the evening. Share it with your doctor if you're seeking help. Many people discover simple causes, such as a late cup of tea, a long afternoon nap, or an irregular bedtime.
