Many older people experience insomnia, which can be due to mental health issues, medical conditions, and lifestyle changes. Treatment may involve improving sleep habits, therapy, and medication.

Some estimates suggest that up to 50% of older adults report symptoms of insomnia. However, insomnia is not a natural part of aging — many older people have no issues with sleeping.

Insomnia occurs when a person has difficulty falling asleep or getting good-quality sleep. Several treatments and therapies may help that a doctor should tailor to a person’s needs.

This article reviews the causes of insomnia, its symptoms, the effects of inadequate sleep, and treatment.

As a person gets older, they often experience changes in routines, behaviors, medications, and overall health. These can increase the risk of developing a sleep disturbance such as insomnia.

For example, a person may develop a new underlying condition, take new medications, and alter their lifestyle following retirement, all of which can put them at a higher risk of developing insomnia.

In addition, evidence suggests that a person will experience changes in their circadian rhythm as they age. These changes mean that an older adult may find that their average sleep per night decreases to between 5 and 7 hours until about age 60 when it plateaus.

There are several possible risk factors and causes of insomnia in older adults. They include both underlying medical or psychiatric conditions as well as reactions to medications.

Medical conditions

  • changes to environment, such as moving to a new home
  • excessive napping during the day

A healthcare professional may ask about a person’s sleep habits and any symptoms they are experiencing.

Healthcare professionals define insomnia as a person experiencing 3 nights or more in a week of difficulty falling asleep or staying asleep. For chronic insomnia, the sleeping issues must occur for 3 or more months.

In addition to assessing sleep, a healthcare professional may perform additional checks to determine if the lack of sleep is occurring alongside other conditions, such as heart disease, depression, or other conditions.

Treatment can vary between people. It often involves a combination of medications, natural remedies, and changes to sleep routines.

Experts generally recommend that a person plays an active role in developing their treatment plan to help them stick to it. The goal of treatment is to reduce the amount of sleep loss and help prevent daytime symptoms and possible complications.

Cognitive behavioral therapy for insomnia (CBTi) is a first-line treatment for insomnia. The technique incorporates several cognitive and behavioral techniques to help improve both short- and long-term sleep quality.

Medications

Several medications may help with insomnia. A person should work with a healthcare professional to determine the best medications for them and discuss any potential side effects before starting a new medication.

Some options include:

Natural remedies

A 2018 study suggests that melatonin and valerian root are alternative or complementary medicine options for insomnia. Though both are associated with only mild side effects, lack of regulation means formulas and doses can vary greatly between brands and products.

As with other medications, a person should discuss the use of melatonin, valerian root, or other herbs or supplements with a healthcare professional before taking them.

Other treatments

Several nonpharmaceutical options may help with insomnia. Some suggestions include developing healthy sleep habits, such as:

  • eating a balanced diet that includes sufficient iron and vitamins
  • getting regular exercise
  • avoiding alcohol, nicotine, and caffeine close to bedtime
  • making the bedroom an inviting space for sleep with cool temperatures, making it dark, and not having electronic devices
  • avoiding naps
  • eating meals on a regular schedule
  • avoiding certain medications
  • taking steps to manage stress
  • limiting fluids before bedtime
  • going to sleep and waking up around the same time each day
