If getting a good night’s sleep seems harder than it used to be, you’re not imagining it.
Adults over 50 frequently report getting less sleep — and often find themselves waking earlier, sleeping more lightly, or getting up several times throughout the night.
“While older adults may find it harder to obtain adequate sleep, the biological need for sleep does not significantly decrease as you age,” says
Saema Tahir, MD, a board-certified sleep medicine physician and pulmonologist with a private practice in New York City. “Changes in sleep duration and quality are common with age, but should not be considered simply ‘normal’ or ignored — they carry real health consequences.” Poor sleep has been linked to a higher risk of
heart disease,
cognitive decline, and mental health conditions like
depression.
Fortunately, understanding age-related biological changes — including shifts in metabolism, hormones, and the body’s internal clock — can help you take steps to improve your sleep and support healthy aging.
1. Metabolism Changes Can Interfere With Sleep — Support Both With Healthy Daily Habits
As you age, your
metabolism naturally changes. Muscle mass tends to decline, fat distribution shifts, and age-related changes in fat tissue can contribute to
insulin resistance, which makes it harder for the body to regulate blood sugar efficiently.
Your metabolism is also closely linked with sleep. Poor or insufficient sleep can disrupt blood sugar regulation, appetite hormones, and other metabolic processes — potentially contributing to insulin resistance and weight gain. In turn, metabolic conditions such as
obesity and
type 2 diabetes are commonly linked to sleep disorders like
obstructive sleep apnea. Over time, this can create a cycle in which poor sleep contributes to poorer metabolic health, which may further interfere with healthy sleep.
“What I really emphasize is that no hack, pillow, or supplement will fix sleep,” Dr. Tahir says. “Eating your last meal at least three hours before bed, reducing refined carbohydrates and alcohol, and maintaining physical activity all have evidence supporting improved sleep quality through metabolic pathways.”
2. Melatonin Naturally Declines With Age, but You Can Still Strengthen Your Body’s Sleep Signals
Melatonin is a hormone that helps regulate your body’s internal clock by signaling when it’s time to feel sleepy. Its production is closely tied to light exposure, rising in response to darkness to promote sleepiness and falling with morning light to help you wake up.
Beginning around age 40, the body gradually produces less melatonin at night, and the timing of its release may also shift — making it harder to fall and stay asleep.
Rather than relying on
melatonin supplements alone, which can interfere with medications and cause daytime drowsiness in older adults, experts recommend strengthening your body’s natural sleep signals through light exposure and
daily routines.
“Get bright outdoor light during the day, especially in the morning, and keep your evenings dim and relaxing by reducing bright screens and overhead lights close to bedtime,” says Junxin Li, PhD, RN, an associate professor at Johns Hopkins School of Nursing in Baltimore, who researches the impact of aging on sleep. “A regular sleep-wake schedule, consistent meal timing, and limiting alcohol near bedtime can also support the circadian system.”
3. Addressing Hormonal Changes Can Help Relieve Sleep Issues in Menopause and Beyond
Menopause affects more than reproductive health.
For many women, declining estrogen, which helps regulate body temperature, and progesterone, which has sleep-promoting effects, can contribute to
night sweats, nighttime awakenings, and difficulty falling asleep.
Mood changes and other menopause-related symptoms can further disrupt sleep.
And these
sleep issues may persist years after your final menstrual period.
“Often what happens is that hormonal changes and other symptoms, like hot flashes, first cause insomnia to develop during menopause,” says Philip Gehrman, PhD, a professor of clinical psychology in psychiatry at the Hospital of the University of Pennsylvania in Philadelphia, and a behavioral sleep medicine research expert who has researched sleep disorders in older adults. “But then the insomnia takes on a life of its own, persisting into the postmenopausal period.”
Dr. Gehrman suggests tailoring sleep strategies to symptoms. For
night sweats, consider tactics like keeping your bedroom cool, choosing lightweight bedding and sleepwear, and discussing persistent symptoms with your healthcare provider. Treatments like
cognitive behavioral therapy for insomnia (CBT-I) involve working short-term with a healthcare professional to work on your bedtime routine and other sleep-related behaviors and can help improve sleep over time.
4. If You’re Getting Less Deep Sleep Than You Used to, Focus on Sleep Quality
The structure of your sleep naturally changes with age. Beginning in midlife, adults gradually spend less time in deep, slow-wave sleep — the
sleep stage most associated with physical recovery and feeling refreshed — and may wake more often throughout the night.
This shift is thought to stem, in part, from age-related changes in the brain’s sleep-regulating neurons, Tahir explains. Research suggests that aging can weaken the body’s internal clock and its ability to build up the pressure needed to sleep, which contributes to earlier and more fragmented sleep.
As a result, even spending enough hours in bed can leave you feeling tired the next day.
Although researchers haven’t identified an evidence-backed way to restore the deep sleep lost with aging, healthy habits can help you get more restorative sleep. Exercise may promote deeper sleep, while limiting alcohol near bedtime and treating
sleep disorders can prevent disruptions that fragment sleep.
Many older adults can train their brains for more effective sleep. Gehrman says CBT-I uses behavioral strategies to train the brain to associate the bed with sleep rather than wakefulness and establish a more consistent sleep-wake pattern.
“Cognitive behavioral strategies can help reduce time spent awake — including keeping a regular sleep and wake schedule, winding down before bed, and getting out of bed to do relaxing activities if you’re unable to sleep,” he adds.
5. Cortisol Level Shifts Can Be Managed With Stress Relief Techniques
Cortisol, a main stress hormone, normally follows a daily cycle — dropping at night to promote sleep and rising in the morning to wake you up.
For some, this rhythm may become altered during menopause, prompting
higher evening cortisol levels that can contribute to difficulty falling asleep or nighttime awakenings.
To support a healthy cortisol rhythm for sleep, Li underscores the importance of sticking to a set bedtime and prioritizing
stress management in your daily routine.
“A calming wind-down routine before bed — such as slow breathing, meditation, gentle stretching, reading, or other relaxing activities — can help signal safety and reduce nighttime alertness,” Li says. “It’s also helpful to avoid stressful work, intense conversations, news, TV shows, or problem-solving right before bed.”
6. Bladder Changes Can Be Mitigated by Tweaking Your Fluid Intake
Getting up to use the bathroom more than once, known as
nocturia, is a common reason adults over 50 wake up during the night.
Age-related changes in the bladder and kidneys can increase nighttime urine production, making bathroom trips more frequent.
Shifts in hormones that regulate fluid balance, along with medical conditions that are common with age, like an
enlarged prostate and obstructive sleep apnea, can also contribute to nocturia.
“Nocturia is one of the most common causes of sleep fragmentation in this age group,” Tahir says. “Evidence-based strategies include restricting fluids after 6 p.m., reducing caffeine and alcohol intake, treating underlying contributors like prostate or bladder issues, and timing any diuretic medications to the morning rather than evening.”
