Sleep is important for people of all ages, but older people's sleep patterns are impacted by multiple factors, from medical conditions to medications. While it is often said that older people need less sleep, the current recommended sleep guidelines for all adult age groups are almost identical. According to the National Sleep Foundation, adults between 18 and 64 should aim for seven or more hours of sleep a night, while those 65 and older should get seven to eight hours. However, older people tend to go to bed earlier and wake up earlier, and their sleep tends to be shorter and lighter, with more frequent awakenings. Sleep disorders, such as insomnia, sleep apnea, and restless legs syndrome, become more common with age. Additionally, factors such as illness, medications, mental health, and pain can further impact sleep quality and duration in older adults.

What You'll Learn
Insomnia is the most common sleep problem in older adults
Sleep is an essential part of our lives, and as we age, our sleep patterns change. Older adults tend to go to bed earlier and wake up earlier, and the quality of their sleep may be impacted. While older adults need around seven to nine hours of sleep, just like all other adults, many struggle with sleep issues.
There are various factors that contribute to insomnia in older adults. One factor is the natural changes to their circadian rhythm and sleep-wake cycle. Older adults are more susceptible to circadian rhythm sleep disorders because the internal mechanisms regulating this rhythm deteriorate with age. Advanced sleep-wake phase disorder is common in older adults, causing them to feel tired in the early evening and wake up very early.
Additionally, older adults may experience insomnia due to medical conditions and medications. Medical conditions can cause pain, which can disrupt sleep, creating a vicious cycle where less sleep leads to more pain. Medications can also impact sleep, making individuals very sleepy during the day and interfering with their nighttime rest. Furthermore, certain medications can worsen underlying sleep disorders.
The treatment of insomnia in older adults can be complex. While prescription sleep medications are available, they are intended for short-term use and carry risks such as daytime sleepiness, especially in older individuals. Cognitive behavioural therapy, a form of counselling, can be beneficial. Maintaining healthy habits at bedtime, such as a consistent sleep schedule and avoiding caffeine and alcohol, can also help prevent and manage insomnia.

Older people tend to go to bed and wake up earlier
While older adults need the same amount of sleep as younger adults—about seven to nine hours each night—their sleep patterns differ. Older people tend to go to bed and wake up earlier than younger adults. This shift in sleep schedule is known as advanced sleep phase syndrome, which is caused by changes in the body's internal clock as one ages.
This phenomenon is supported by research indicating that older adults take naps more frequently than younger adults. According to the National Library of Medicine, approximately 25% of older adults nap during the day, compared to only 8% of younger adults. While napping can be beneficial, excessive or late napping can disrupt nighttime sleep, contributing to the earlier bedtime observed in older individuals.
The earlier sleep schedule in older adults may also be influenced by social factors. Social interactions provide cues that help maintain a regular sleep-wake rhythm. Therefore, social isolation, which is more prevalent among older adults, can impact their sleep patterns and contribute to earlier bed and wake times.
Additionally, older adults may experience changes in their ability to metabolize substances like caffeine, nicotine, and alcohol. These substances can disrupt sleep, further influencing the sleep patterns of older individuals and potentially contributing to their preference for earlier bed and wake times.
While the exact reasons for the shift in sleep schedules with age are multifaceted, it is clear that older adults tend to adhere to earlier sleep and wake times compared to their younger counterparts, even while maintaining similar total sleep requirements.

Sleep disorders become more common with age
Older adults need about the same amount of sleep as all other adults, which is seven to nine hours each night. However, older people tend to go to bed earlier and wake up earlier. Sleep becomes lighter and shorter, and one may wake up more often during the night. Many older adults don't sleep well.
Pain and sleeplessness can become a vicious cycle, in which less sleep can lead to more pain. Other issues that may affect older adults are chronic pain, such as arthritis, and cardiovascular disease. Nighttime urination, or nocturia, also increases with age, affecting up to 80% of older adults and contributing to disrupted sleep.
Older people are at a higher risk of circadian rhythm sleep disorders due to the internal mechanisms that regulate sleep deteriorating with age. Advanced sleep-wake phase disorder is common in older populations, with people routinely feeling tired in the early evening and waking up between 3 am and 5 am. Timed light exposures in the evening and a regimented sleep schedule can be used to treat these disorders.
REM sleep behaviour disorder (RBD), where people physically act out their dreams, sometimes violently, is also more common in older people. RBD has been found to be unusually prevalent in elderly men.

Medical conditions and medication can disrupt sleep
Older adults are more likely to have medical conditions and take medications that can affect their sleep. Medical conditions can cause pain, sleeplessness, and other sleep-disruptive symptoms. Additionally, certain medications can make individuals very sleepy during the day and make it difficult for them to sleep at night.
Medical Conditions
Several medical conditions can disrupt sleep in older adults. These include:
- Pain: Chronic pain conditions, such as arthritis, can make it difficult to fall asleep and impact overall sleep quality.
- Nocturia: Nighttime urination increases with age due to physical changes in the urinary system, affecting up to 80% of older adults.
- Respiratory Conditions: Lung or respiratory issues, such as chronic obstructive pulmonary disease (COPD) and asthma, can increase the risk for obstructive sleep apnea.
- Neurodegenerative Disorders: Conditions such as Parkinson's disease and Alzheimer's disease can cause sleep disturbances. Up to 40% of people with Parkinson's disease experience obstructive sleep apnea.
- Cardiovascular Disease: Research indicates that 39% of people with cardiovascular disease sleep fewer than 6.5 hours, resulting in an increased risk of death.
- Mental Health Disorders: Depression, anxiety, bipolar disorder, and other psychiatric disorders can contribute to insomnia and disturbed sleep patterns.
Medications
Medications can also significantly impact sleep in older adults. Certain medications can cause sleep disruption or excessive sleepiness:
- Stimulating Medications: Some medications have stimulating effects, including antidepressants (particularly selective serotonin reuptake inhibitors), decongestants, bronchodilators, certain antihypertensives, and corticosteroids. These can make it difficult to fall asleep or maintain a restful sleep.
- Sedating Medications: Long-acting sedatives or sleep aids can cause excessive daytime sleepiness and may lead to falls and accidents.
- Diuretics: Nighttime use of diuretics can disrupt sleep by increasing the need to wake up and use the bathroom.
- Sleep Medications: While sleep medications can be helpful in the short term, they carry risks and should not be relied upon long-term. They may cause dependence, and their effectiveness may decrease over time, requiring higher doses.
The impact of medical conditions and medications on sleep highlights the importance of consulting a doctor or healthcare provider for personalized advice and treatment options.

Lack of physical activity can impact sleep quality
Older adults are recommended to get seven to nine hours of sleep each night. However, factors such as medical conditions, medications, mental health, and pain can impact their sleep quality and duration. One factor that can significantly influence their sleep is their level of physical activity.
Lack of physical activity can disrupt the sleep/wake cycle, making it difficult for older adults to maintain a healthy sleep rhythm. This disruption can lead to shorter and lighter sleep patterns, causing them to wake up more frequently during the night.
Regular physical activity has been linked to improved sleep quality and the management of sleep disorders. Moderate-intensity exercises, in particular, have been shown to be beneficial in enhancing sleep quality in older adults. The release of endorphins through exercise can lower stress and anxiety levels, promoting relaxation and better sleep. Additionally, exercise stimulates the release of neurotransmitters such as serotonin and norepinephrine, which are crucial for mood regulation and relaxation, further aiding in sleep initiation and maintenance.
The bidirectional relationship between sleep and exercise is evident, as a good night's sleep can also increase motivation and energy levels for physical activity during the day. However, it is important to note that the intensity of exercise may vary for different individuals, and personalized recommendations are essential for optimizing exercise routines to improve sleep.
In summary, a lack of physical activity can impact the sleep quality of older adults by disrupting their sleep/wake cycle and affecting their overall health. Engaging in regular moderate-intensity exercises can help improve their sleep patterns and overall well-being.
