Key takeaways

  • Insomnia can be caused by pain, medications, sleep apnea, mood, bladder symptoms and routines.
  • Sleep medicines can increase fall and confusion risk in older adults.
  • Persistent or sudden sleep changes deserve medical review.

Why sleep changes with age

Older adults may sleep more lightly, wake earlier or wake more often. These changes do not mean severe insomnia should be ignored.

Poor sleep can worsen daytime fatigue, attention, mood and fall risk.

Common causes

Pain, restless legs, sleep apnea, nighttime urination, depression, anxiety, caffeine, alcohol and irregular routines can all contribute.

New insomnia can also follow illness, hospitalization, grief or medication changes.

Medication considerations

Some prescriptions, over-the-counter products and supplements can affect sleep. Sedating medicines may increase confusion or falls.

Older adults should ask before using sleep aids, antihistamines or alcohol for sleep.

Sleep hygiene

Helpful habits may include a consistent wake time, a calming bedtime routine, comfortable room temperature and limiting screens close to bedtime.

The bed should be associated with sleep rather than long periods of wakeful worrying.

Daytime light and activity

Morning light, gentle movement and social routine can help regulate the sleep-wake cycle.

Long late-day naps may make nighttime sleep harder for some people.

When insomnia needs review

Medical review is important when insomnia is persistent, paired with snoring or breathing pauses, linked to falls or causing severe daytime impairment.

When to contact a healthcare professional

Seek prompt medical advice for sudden confusion, falls, severe depression, suicidal thoughts, breathing pauses during sleep or insomnia after a medication change.
