Key points
What changes with age
A large meta-analysis of sleep recordings shows that as we age, it takes a little longer to fall asleep, light sleep takes up more of the night and REM sleep (when most dreaming happens) decreases[3].
The National Sleep Foundation suggests 7 to 8 hours of sleep after 65, compared with 7 to 9 hours for younger adults[4]. To find out more: how much sleep you really need.
Normal ageing, or insomnia?
Slightly lighter sleep or waking a little earlier is not an illness. We call it insomnia when the difficulties occur at least three nights a week for at least three months and affect your days: tiredness, concentration, mood[6]. At that point it isn't “just age”: insomnia can be treated at any age.
In older people, some causes are worth looking into with your doctor: pain, needing to pass urine at night, sleep apnoea, restless legs, medicines, low mood. See Do I have insomnia? and waking up at night.
Sleeping pills: greater risks
After 65, sleeping pills (benzodiazepines, zolpidem, zopiclone) carry a higher risk of prolonged sedation, memory problems, confusion and falls, with a risk of hip fracture. The Belgian general practice guideline sees no place for a sleeping pill as a first-line option in older people: the benefit is too small to justify the risks[5].
Never stop suddenly
If you have been taking a sleeping pill for a long time, don't stop it on your own: stopping suddenly can cause withdrawal. Talk to your doctor, who can plan a very gradual reduction. See Sleeping pills and CBT-I.
CBT-I works after 60 too
CBT-I is the first-line recommendation for chronic insomnia, whatever your age[6]. In older adults, a meta-analysis of 14 studies shows a clear improvement in sleep efficiency (about 8 percentage points), with less time awake at night (about 23 minutes) and faster sleep onset[1].
In digital form, 9 trials involving 760 people aged 60 and over show a drop of about 4 points in insomnia score, still present at follow-up. The authors point out that these results mainly apply to “younger seniors” and that follow-up is still limited[2].
Gentler settings
For older adults, the authors of the method suggest more flexible adjustment thresholds for the sleep window[7]. In ReSomnia, from age 65, cautious settings apply: the window never goes below 5 hours 30 minutes, and it widens as soon as sleep efficiency reaches 85% (instead of 90%).
To understand the method: sleep restriction and stimulus control. One extra precaution when you get up at night: a night light to show the way lowers the risk of falling.
