Sleep Recommendations for Older Adults (65+ Years)

While the total amount of sleep needed decreases only slightly in older adulthood, the architecture of sleep changes meaningfully. Deep sleep may account for less than 5% of total sleep time in adults over 70, compared to 15-20% in younger adults. This reduction in deep sleep has implications for immune function, tissue repair, and memory consolidation. REM sleep also decreases modestly but remains important for cognitive health. Research from the National Institute on Aging has linked poor sleep quality in older adults to accelerated cognitive decline, increased risk of Alzheimer's disease, higher rates of falls and accidents, and greater overall mortality. Sleep apnea affects an estimated 20-40% of older adults and is significantly underdiagnosed in this population. Insomnia is the most common sleep complaint, affecting roughly half of adults over 65. Restless leg syndrome, periodic limb movement disorder, and REM sleep behavior disorder also become more prevalent with age.

Maintain a consistent sleep-wake schedule aligned with your natural circadian preferences — if you naturally wake at 5:30 AM, set your bedtime accordingly to ensure 7-8 hours of opportunity for sleep. Get bright light exposure during the morning and early afternoon to reinforce circadian signals. Stay physically active with age-appropriate exercise such as walking, swimming, or gentle yoga — regular physical activity is one of the strongest predictors of sleep quality in older adults. Review all medications with your healthcare provider, as many common medications including beta-blockers, diuretics, antidepressants, and corticosteroids can disrupt sleep. Limit fluid intake in the evening to reduce nighttime bathroom trips. Avoid using alcohol as a sleep aid — its sleep-disrupting effects are amplified in older adults. If you enjoy napping, keep naps short and before 3 PM.

Excessive daytime sleepiness that interferes with activities, frequent napping that exceeds 1-2 hours per day, taking more than 30 minutes to fall asleep regularly, or waking more than 2-3 times per night with difficulty returning to sleep may indicate a treatable sleep disorder. Loud snoring, observed breathing pauses, and gasping during sleep are hallmarks of sleep apnea and should be evaluated promptly. Unusual sleep behaviors such as acting out dreams, sleep-related eating, or confusion upon waking warrant medical evaluation. Cognitive changes including increased forgetfulness, difficulty finding words, and impaired judgment may be worsened by or partially caused by undiagnosed sleep disorders.
