Sleep is essential for our physical and emotional health, and the quality and duration of sleep can change as we age. While older adults need the same amount of sleep as younger adults, they often experience more disturbances and find it harder to fall asleep. This misconception that older people require less sleep contributes to the notion that poor sleep is a normal part of ageing, but it is not. Sleep disorders and insomnia are common among older adults, and can lead to serious health issues such as an increased risk of cardiovascular disease, diabetes, weight problems, and breast cancer in women. Additionally, sleep-disordered breathing, such as sleep apnea, has been linked to a higher risk of dementia and other neurodegenerative conditions. However, many older adults report few or no sleep problems, and maintaining good sleep hygiene and developing healthy habits can promote better sleep as we age.

Sleep disorders and insomnia
Sleep is a complex process, with multiple parts of the brain working together to prepare the body for sleep. As we age, our bodies undergo several changes that can significantly affect our sleep quality and patterns. Older people tend to experience less time in the "slow-wave" NREM stage of sleep, causing them to wake up more frequently during the night. They spend less time in deep sleep, resulting in an average of 3 to 4 awakenings per night. This can lead to feelings of sleep deprivation, even if their total sleep time remains unchanged.
Older adults are susceptible to various sleep disorders, with insomnia being the most prevalent. Insomnia is characterised by difficulty falling asleep or maintaining sleep, resulting in significant daytime impairments. These impairments may include excessive sleepiness, fatigue, mood disturbances, and difficulty concentrating. The risk of insomnia increases with age, affecting 10-30% of older adults. It is often associated with other medical and psychiatric conditions, such as sleep-disordered breathing, restless leg syndrome, and movement disorders.
Several factors contribute to insomnia in older adults. These include stressful life events, medical conditions, medications, and behavioural changes. Older individuals with insomnia are at an increased risk of developing depression, anxiety, and suicidal tendencies. They are also more susceptible to heart disease, hypertension, and stroke. It is crucial to address insomnia and seek appropriate treatment, as it can significantly impact one's health and well-being.
Treating insomnia in older adults requires careful consideration. While sleep medications can provide short-term relief, they carry risks of dependence and withdrawal and should be avoided or used with caution in older adults. Cognitive behavioural therapy, healthy habits, and creating a peaceful bedroom environment are recommended approaches to managing insomnia in this population. Additionally, older adults should ensure proper sleep hygiene, limit daytime napping, and avoid substances that can disrupt sleep, such as caffeine and alcohol.
In summary, insomnia is a common sleep disorder among older adults, often coinciding with other medical and psychiatric conditions. Effective management of insomnia involves a comprehensive approach that includes non-pharmacological interventions, lifestyle modifications, and, in some cases, careful use of sleep medications under medical supervision. By addressing insomnia and improving sleep quality, older adults can enhance their overall health and well-being.

Sleep duration and quality
Sleep is essential for both physical and emotional health, helping to improve concentration and memory formation, facilitating cell repair, and boosting the immune system. While sleep needs change throughout a person's lifetime, older adults require a similar amount of sleep to younger adults, with seven to nine hours per night recommended. However, many older adults experience changes in sleep quality and duration. They may take longer to fall asleep, sleep less deeply, and wake up more frequently, leading to a perception of sleep deprivation even when total sleep duration remains unchanged.
Older adults often face challenges in obtaining adequate sleep due to various factors. One reason is the decrease in melatonin production, the hormone that promotes sleep. Additionally, older individuals may experience more disruptions during sleep, resulting in less time spent in deep, dreamless sleep. They may also be more susceptible to conditions like insomnia, which affects almost half of adults aged 60 and older. This can be caused by stress, changes in routine, or underlying medical issues. Other factors contributing to sleep disruption include nocturia (night-time urination), anxiety, discomfort, and pain from chronic illnesses.
To address sleep difficulties, older adults should consider improving sleep hygiene and developing healthy habits. This includes adopting soothing bedtime rituals such as taking a bath, listening to music, or practicing relaxation techniques like progressive muscle relaxation, mindfulness meditation, or deep breathing. It is also important to limit the use of sleep aids and sleeping pills, as they can have side effects and may not address the root causes of insomnia. Cognitive behavioral therapy and certain medications, such as antidepressants or mild antihistamines, can be effective in managing insomnia under medical supervision.
Additionally, older adults should be mindful of their sleep schedules and adjust their bedtimes to match when they naturally feel tired. Napping can be beneficial, but it should be limited to short durations of 15 to 45 minutes to avoid disrupting nighttime sleep. Maintaining a sleep diary or using sleep-tracking tools can help identify patterns and concerns to discuss with a doctor or sleep specialist.
While aging brings changes in sleep patterns, it is important to understand that poor sleep is not an inevitable part of growing old. Many healthy older adults report minimal or no sleep problems, and there are treatments available for those who do. By addressing the unique sleep needs of older adults and promoting better rest, we can enhance their overall health and quality of life.

Sleep patterns and changes
Sleep patterns change as we age, but disturbed sleep and daytime drowsiness are not a normal part of ageing. Older adults need about the same amount of sleep as younger adults—seven to nine hours per night. However, older people tend to go to bed earlier and wake up earlier than they did when they were younger.
Older people may experience changes in the quality and duration of their sleep. They may find it harder to fall asleep and spend more time in bed trying to sleep. Older people may also sleep more lightly and experience abrupt transitions between sleep and wakefulness. They are more likely to wake up multiple times during the night, with one source stating that older people wake up an average of three to four times each night. This is because they spend less time in deep, dreamless sleep.
Older people may also experience more disruptions during sleep, including those caused by nocturia, or nighttime urination, which becomes more common with age due to physical changes in the urinary system. Other causes of sleep disruption include anxiety, discomfort, and pain from chronic illnesses. Obstructive sleep apnea, which is more common in older adults, can also cause disrupted sleep. This occurs when throat muscles relax during sleep, blocking the airway.
Many older adults experience insomnia, the persistent difficulty in falling or staying asleep. Insomnia may be caused by various overlapping factors, such as stress, changes in routine, or underlying medical conditions. While short-term insomnia can be managed with sleep medicines, these should not be used long-term due to associated risks. Instead, older adults with insomnia may benefit from cognitive behavioural therapy or developing healthy habits at bedtime.

Sleep medications and alternatives
Older adults need about seven to nine hours of sleep each night, which is similar to the sleep requirements of younger adults. However, older people tend to go to bed and wake up earlier than they did when they were younger. Many older adults experience changes in the quality and duration of their sleep, and some may find it challenging to get sufficient sleep.
Older adults respond differently to medications than younger individuals, and it is essential to consult a healthcare provider before taking any sleep medications. While sleep medicines can provide temporary relief, they should ideally be avoided or used sparingly due to the risk of dependence and addiction.
Medications
- Antidepressants: Certain antidepressants can be beneficial if depression affects sleep. Some options, such as trazodone, mirtazapine (Remeron), amitriptyline (Elavil), and nortriptyline (Pamelor), are used off-label to treat insomnia. However, the evidence for their effectiveness in treating insomnia is limited.
- Antihistamines: Mild antihistamines can be more effective than sleeping pills for short-term insomnia relief. However, most health experts do not recommend them for older adults.
- Melatonin supplements: These supplements are generally safe for short-term use and can help individuals fall asleep faster, aiding in jet lag reduction. Controlled-release melatonin is recommended as a first-line agent in older adults.
- Z-drugs: Zolpidem, eszopiclone, and zaleplon are commonly prescribed for insomnia and can be considered if first-line agents are ineffective. However, they carry a risk of dependence and should be used with caution.
- Doxepin: This medication has been shown to improve sleep efficiency and total sleep time at doses of 3 and 6 mg. It has a favorable adverse effect profile in older adults and can be considered for short-term use.
Alternatives
- Cognitive Behavioral Therapy (CBT): CBT is a type of counseling that can help manage insomnia and improve sleep habits.
- Healthy Habits: Developing healthy bedtime habits can prevent or manage insomnia. This includes avoiding alcohol, which can disrupt sleep later in the night, and limiting caffeine and exercise close to bedtime.
- Sleep Diary: Keeping a sleep diary can help identify patterns and triggers for insomnia.
- Address Pain and Discomfort: If pain or discomfort from chronic illnesses is interfering with sleep, it is important to consult a doctor for appropriate management.
- Treat Sleep Apnea: Sleep apnea is a common sleep disorder characterized by snoring and airway blockage during sleep. Treatment options include continuous positive airway pressure (CPAP) devices, dental devices, or surgery to keep airways open during sleep.
- Manage Nocturia: Nocturia, or nighttime urination, is common in older adults and can disrupt sleep. Limiting fluid intake before bedtime and addressing any underlying urinary issues can help manage this condition.

Sleep and health
Sleep is essential for both physical and emotional health. A good night's sleep helps improve concentration and memory formation, allows the body to repair any cell damage that occurred during the day, and boosts the immune system, thereby helping to prevent disease.
Older adults need about the same amount of sleep as younger adults, which is seven to nine hours per night. However, older people tend to go to bed and wake up earlier than they did when they were younger. Many older adults experience changes in the quality and duration of their sleep. Older people may spend less time in deep, dreamless sleep, and wake up more frequently throughout the night. They may also experience more disruptions during sleep due to factors such as needing to urinate (nocturia), anxiety, discomfort, or pain from long-term illnesses.
Sleep disorders, such as insomnia, sleep apnea, restless legs syndrome, and periodic limb movement disorder, can also contribute to sleep difficulties in older adults. Insomnia is the most common sleep problem in adults aged 60 and older, with almost half experiencing difficulty falling or staying asleep at least three nights a week. Sleep apnea, which is more common in older adults, can increase the risk of high blood pressure, strokes, heart disease, and cognitive problems. Additionally, research suggests a link between disturbed sleep and a higher risk of developing dementia.
To improve sleep quality, older adults can try developing healthy bedtime habits and improving sleep hygiene. Relaxation techniques, such as deep breathing or meditation, can help, as can adopting soothing bedtime rituals like taking a bath or listening to music. It is also important to address any underlying causes of sleep problems, such as pain or medication side effects, and to consult a doctor if sleep difficulties persist.
