Insomnia in older adults

Overview

Insomnia is trouble falling asleep, staying asleep, or waking up too early and not being able to get back to sleep. In older adults, it is a common sleep problem that can affect your energy, mood, and overall health.

Yes, insomnia is common among older adults. About 30 to 48% of seniors report some form of insomnia.

It affects both men and women, but women are slightly more likely to experience it. People with chronic health conditions or who take multiple medications are also at higher risk.

Symptoms

Common symptoms

• Trouble falling asleep at night
• Waking up often during the night
• Waking up too early and not being able to get back to sleep
• Feeling tired or not rested after a full night’s sleep
• Daytime sleepiness, irritability, or trouble concentrating

Symptoms in children

• Children can have insomnia too, but for older adults the symptoms are more likely linked to other health issues.

Symptoms in older adults

• Waking up multiple times at night and struggling to fall back asleep is very common.
• Spending a lot of time in bed without sleeping.
• Feeling fatigued during the day, which can increase the risk of falls.

Causes

Main causes

• Changes in your natural sleep-wake cycle as you age
• Chronic health conditions like arthritis, heart disease, or diabetes
• Medications that can interfere with sleep (ask your doctor or pharmacist)
• Pain, discomfort, or the need to urinate frequently at night
• Stress, anxiety, or depression

Risk factors

• Being over 65 years old
• Having a chronic illness
• Taking multiple medications
• Living alone or having limited daytime activity
• Drinking caffeine or alcohol close to bedtime

When to see a doctor

See a doctor urgently if:

• If insomnia is causing you to feel unsafe, dizzy, or fall often
• If you have thoughts of harming yourself

Book a routine appointment if:

• If poor sleep lasts longer than a few weeks and affects your daily life
• If you snore loudly and feel very tired during the day
• If your sleep is disturbed by physical pain or frequent bathroom trips

Diagnosis

Your doctor will ask about your sleep patterns, health conditions, and medications. They may ask you to keep a sleep diary for a week or two.

Tests that may be done

• Questionnaires about sleepiness and sleep quality
• Blood tests to check for thyroid problems or low iron
• Sleep study (polysomnography) if sleep apnea or restless legs is suspected

What to expect at your appointment

The doctor will work with you to find the cause. They will review your medicines and medical history. They may suggest tracking your sleep and making simple changes before trying any treatments.

Treatment

Treatment for insomnia in older adults usually starts with healthy sleep habits and non-medical approaches. Medicines are used only when needed and for a short time. Always talk to your doctor before trying any sleep aids.

Self-care at home

• Keep a regular sleep schedule – go to bed and wake up at the same time each day
• Create a calm bedtime routine (reading, gentle stretches, warm bath)
• Make your bedroom comfortable: dark, quiet, and cool
• Avoid large meals, caffeine, and alcohol in the evening
• Get natural light during the day, especially in the morning
• Stay active – gentle exercise like walking can improve sleep

Medical treatments

Your doctor might recommend cognitive behavioural therapy for insomnia (CBT-I), which is a proven non-drug treatment. If needed, certain prescription sleep aids may be used for a short time, but they are not recommended for long-term use in older adults because of risks like falls and confusion. Always follow your doctor’s advice and never stop or change medications without consulting them.

When is surgery considered?

Surgery is not used to treat insomnia. In some cases, surgery for an underlying cause (like sleep apnea) may help improve sleep.

Living with this condition

Living with insomnia can be frustrating, but small changes can make a big difference. Try to be patient with yourself and focus on good sleep habits. If you have a bad night, resist the urge to nap for more than 20 minutes or go to bed much earlier.

Lifestyle tips

• Stay socially active – loneliness can worsen sleep
• Limit screen time before bed – the blue light can keep you awake
• Use the bed only for sleep – avoid working or eating in bed

Diet and exercise

A balanced diet and regular physical activity can improve sleep. Avoid heavy meals near bedtime. Consider a light snack like a banana or warm milk if you’re hungry. Exercise during the day, but not too close to bedtime.

Mental health and emotional wellbeing

Insomnia can make you feel irritable, anxious, or down. It can also affect your memory and concentration. If you notice these feelings, talk to your doctor or a counsellor. Treating insomnia often improves your mood as well.

Prevention

You can reduce your risk of insomnia by keeping a regular sleep schedule, staying active during the day, managing stress, and treating any health conditions early. While you cannot always prevent it, good habits make it less likely.

Screening programmes

There is no routine screening test for insomnia, but your doctor may ask about your sleep during regular check-ups.

Complications

If left untreated

• Higher risk of falls and accidents due to daytime sleepiness
• Worsening of chronic conditions like high blood pressure or diabetes
• Increased risk of depression and anxiety
• Memory problems and reduced quality of life

Long-term outlook

The outlook for older adults with insomnia is good. Most people improve with simple changes and treatment. Even if you have had poor sleep for a long time, working with your healthcare team can help you get better rest and feel more energetic during the day.
