Sleep Changes After 60: What's Normal and What Needs Treatment

Sleep architecture changes measurably with age. Understanding which changes are normal and which signal a disorder worth treating is the first step toward better sleep after sixty.

What Changes Are Normal With Age

Circadian phase advance is the most predictable age-related sleep change. The internal clock shifts earlier, producing earlier sleep onset (8 to 10 p.m. rather than 10 to 11 p.m.) and earlier natural waking. This is a biological shift, not a pathology, and attempting to override it with late-night social schedules typically results in chronic sleep deprivation.

Slow-wave sleep (deep sleep) decreases progressively from young adulthood. A 70-year-old may spend only 5 to 10% of the night in slow-wave sleep compared to 20 to 25% in their twenties. This makes older adults more easily aroused by noise, light, or discomfort. Nighttime awakenings become more frequent and longer.

Sleep efficiency — the percentage of time in bed actually spent asleep — typically drops from 95% in young adults to 80 to 85% in adults over 70. This means an 8-hour time in bed may produce only 6.5 to 7 hours of actual sleep.

Total sleep need does not substantially change with age. The perception that older adults need less sleep is contradicted by the evidence; they need similar amounts but find it harder to obtain them.

When Changes Become Disorders

Obstructive sleep apnea (OSA) becomes more prevalent after 60, affecting an estimated 30 to 50% of older adults to some degree. Weight distribution changes, reduced muscle tone in the upper airway, and anatomical changes increase risk. Untreated OSA is associated with cardiovascular disease, cognitive decline, and increased dementia risk. Warning signs include loud snoring, witnessed apneas, waking with headaches, and excessive daytime sleepiness.

Restless legs syndrome (RLS) affects up to 20% of adults over 65. The uncomfortable urge to move the legs, worse in the evening and at rest, delays sleep onset and disrupts sleep continuity. It is treatable and underdiagnosed in this population.

Periodic limb movement disorder (PLMD) involves repetitive leg movements during sleep that the person is often unaware of but that fragment sleep significantly.

Circadian rhythm sleep disorder in the advanced sleep phase variety (ASPD) causes sleep onset before 8 p.m. and waking before 4 a.m. While related to normal phase advance, severe cases benefit from treatment including evening light therapy.

Medications and Sleep

Adults over 65 take an average of five prescription medications. Many have sleep-disrupting effects as primary or secondary actions: beta-blockers reduce melatonin, diuretics cause nocturia, corticosteroids increase arousal, decongestants are stimulants, and some antidepressants suppress REM sleep. A medication review with a pharmacist focused on sleep effects is often among the highest-yield interventions available.

Sedative-hypnotics prescribed for sleep in this population carry significant risks including falls, cognitive impairment, and dependency. The American Geriatrics Society explicitly lists benzodiazepines and related drugs (Ambien, Lunesta) on the Beers Criteria of medications to avoid in older adults.

Evidence-Based Interventions

Cognitive behavioral therapy for insomnia (CBT-I) is the recommended first-line treatment for chronic insomnia in older adults by both the American Academy of Sleep Medicine and the European Sleep Research Society. It is more effective than medication in the long term and has no side effects. Stimulus control, sleep restriction therapy, and relaxation training are its core components.

Morning light exposure resets the circadian clock earlier and can partially counteract advanced phase. Thirty minutes of outdoor light before 9 a.m. is more effective than any supplement for circadian regulation.

Mattress Considerations After 60

Pain is the most common sleep disruptor in older adults, and mattress inadequacy is a frequent contributor. Joints become more pressure-sensitive with age. A mattress that was adequate at forty may cause hip and shoulder pain at sixty-five. Medium-firm mattresses that provide both support and cushioning typically score highest in studies of older adult sleep quality.

Ease of getting in and out of bed becomes relevant with reduced hip and knee mobility. Mattress height combined with a supportive base affects daily function, not just sleep quality.
