After age 70, the brain produces less melatonin, the hormone responsible for deep, restorative sleep. At the same time, the body’s internal clock becomes more sensitive to light, noise, and small disturbances.
As a result:
Nighttime awakenings become more frequent
Falling back asleep takes longer
You may feel tired despite spending many hours in bed
This isn’t classic insomnia. It’s a natural neurological shift associated with aging.
Helpful habits
Get sunlight exposure in the morning
Reduce bright screens and harsh lighting in the evening
Keep consistent sleep and wake times
