Sleep changes with age: older adults may sleep less, spend less time in deep sleep, and wake up more often. Sometimes sleep problems become a sign of insomnia. Let's look at how to distinguish normal from pathology and when to see a doctor.
How sleep changes with age
Aging affects sleep structure: older adults sleep less, spend less time in deep sleep, and wake up more easily. Not only the number of hours matters, but also sleep quality. Sleep helps the body restore its strength, and with frequent awakenings some sleep stages may be insufficient, which affects well-being and health.
Age-related insomnia: how it manifests
Insomnia is regular sleep problems. In older adults it may manifest as difficulty falling asleep, frequent nighttime awakenings, early awakening, and inability to fall back asleep. During the day a person feels tired, irritable, and has difficulty concentrating. If this condition lasts less than 3 months, it is short-term insomnia; if longer, it is long-term.
Causes of insomnia in old age: illnesses and medications
The causes of insomnia in older adults are diverse. Among them are stress, anxiety, depression, noise, an uncomfortable bed, a room that is too hot or too cold. Alcohol, caffeine, and nicotine also disrupt sleep. Many diseases can cause insomnia: Alzheimer's or Parkinson's disease, restless legs syndrome, hyperthyroidism, menopause, chronic pain, sleep apnea. Some medications also contribute to sleep disturbance.
Why insomnia is dangerous for older adults
Poor sleep is not just fatigue: it can affect physical and mental health, thinking, and daily activity. Therefore, with prolonged sleep problems it is better to see a doctor.
How a doctor assesses sleep problems
The doctor will ask about the nature of sleep, lifestyle, diseases, and medications taken, and will perform an examination. To diagnose sleep disorders, polysomnography may be performed — a study that records brain activity, eye movements, breathing, heart rhythm, and other indicators during nighttime sleep. If another sleep disorder is suspected, such as apnea, the person may be referred to a sleep clinic.
When to see a doctor
You should see a doctor if changing sleep habits has not helped, sleep problems last for months, or insomnia interferes with daily life. The doctor will help find the cause and suggest appropriate treatment, such as cognitive behavioral therapy. Medications are prescribed rarely and only for a short period.
- Difficulty falling asleep that lasts more than 30 minutes.
- Frequent nighttime awakenings and problems falling asleep after them.
- Early awakening and inability to fall back asleep.
- Feeling tired and irritable during the day.
- Difficulty concentrating due to lack of sleep.
Insomnia by itself is not a reason to call an ambulance; 103/112 — for life-threatening conditions, for example signs of stroke or heart attack.
