6 Things People Over 50 Should Know About Optimizing Sleep

From everydayhealth.com 

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.

Although these changes become more prevalent with age, experts caution against accepting them as inevitable. Despite the common misconception that older adults require less sleep, most still need seven to nine hours nightly to support overall health and well-being.

“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 apnoea. Over time, this can create a cycle in which poor sleep contributes to poorer metabolic health, which may further interfere with healthy sleep.

Healthy daily habits can support both sleep and metabolic health. Regular physical activity, for example, supports healthy aging and may also help improve sleep quality and sleep efficiency in older adults.

“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 signalling 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 oestrogen, which helps regulate body temperature, and progesterone, which has sleep-promoting effects, can contribute to night sweats, night-time 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 behavioural 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 behavioural therapy for insomnia (CBT-I) involve working short-term with a healthcare professional to work on your bedtime routine and other sleep-related behaviours and can help improve sleep over time.

Hormone therapy (HT) may also promote better sleep for some women during perimenopause or menopause by reducing sleep disruptors like hot flashes and night sweats.

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 behavioural strategies to train the brain to associate the bed with sleep rather than wakefulness and establish a more consistent sleep-wake pattern.

“Cognitive behavioural 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 night-time 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 night-time 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 night-time 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 apnoea, can also contribute to nocturia.

Waking once or twice a night to pee definitely interrupts sleep, but simple lifestyle tweaks and treating underlying medical conditions can provide relief.

“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.”

The Takeaway

• Sleep tends to get lighter and more fragmented with age, but adults older than 50 still need seven to nine hours per night. 
• Several age-related biological changes — including shifts in metabolism, hormones, melatonin production, sleep architecture, and bladder function — make it harder for older people to get restorative sleep.
• Experts advise small daily habits like consistent bedtimes, exposure to daylight, physical activity, smart meal timing, and a comfortable sleep environment, and urge older people to address underlying health conditions with guidance from your healthcare provider to support healthy sleep and aging.
