Sleep is a complex process that becomes more challenging as we age. Older adults often experience changes in their sleep patterns, such as becoming sleepy earlier, waking up earlier, or not sleeping as deeply. While it is a common misconception that older adults require less sleep, the recommended sleep duration for adults remains at seven to nine hours per night. However, many older adults struggle to achieve this due to various factors, including medical conditions, medications, mental health issues, and pain. Sleep disorders such as insomnia, restless legs syndrome, and sleep apnea become more prevalent with age, impacting sleep quality and duration. Additionally, lifestyle choices like alcohol consumption, caffeine intake, and lack of exercise can also contribute to sleep disturbances in older individuals. Understanding the unique sleep needs of older adults and addressing the underlying causes of sleep difficulties are crucial for maintaining their overall health and well-being.

Sleep disorders: Older adults are prone to insomnia, sleep apnea, and restless legs syndrome
Sleep disorders are highly prevalent among older adults, with researchers estimating that between 40% and 70% of older adults experience chronic sleep issues. There are several reasons why a 70-year-old may struggle to sleep some nights, and it is important to identify the underlying causes to address the sleep disturbances effectively.
Insomnia
Insomnia is a common sleep disorder among older adults, characterised by difficulty falling or staying asleep. It can be caused by various factors, including poor sleep habits, such as an inconsistent sleep schedule, daytime napping, and a noisy or bright sleeping environment. Additionally, underlying medical conditions, such as anxiety, bipolar disorder, thyroid disease, depression, and chronic pain, can contribute to insomnia.
Sleep Apnea
Sleep-disordered breathing (SDB), or sleep apnea, is another prevalent sleep disorder in older adults. It involves the complete cessation of breathing (apneas) or partial reduction in breathing (hypopneas) during sleep. Obstructive sleep apnea, a type of SDB, is characterised by the obstruction of the upper airway during sleep, resulting in disrupted breathing patterns. Risk factors for SDB include increasing age, gender, and obesity.
Restless Legs Syndrome (RLS)
Restless legs syndrome (RLS) is a sleep disorder that causes an overwhelming urge to move the legs, often accompanied by uncomfortable sensations. It typically occurs during periods of rest or inactivity, including when trying to fall asleep. While RLS can occur at any age, it may be more prevalent in older adults due to the increased risk factors associated with age.
Other Factors
In addition to these specific sleep disorders, older adults may experience sleep disturbances due to changes in their body's natural internal clock, known as circadian rhythm disruptions. This can result in falling asleep earlier in the evening and waking up multiple times throughout the night. Furthermore, certain medications, herbs, supplements, and recreational drugs can interfere with sleep patterns. Addressing these underlying causes through non-pharmacological treatments, such as cognitive behavioural therapy, sleep hygiene education, and relaxation therapy, can help improve sleep quality in older adults.

Circadian rhythm changes: The body clock shifts, causing early tiredness and wakefulness
Circadian rhythm changes are a common cause of sleep problems in older adults. Circadian rhythms shift with age, gradually becoming earlier in older adulthood. This is known as a "phase advance", where older adults perform mental tasks better in the morning and start to get sleepy earlier in the evening.
The circadian rhythm is the daily pattern of sleep and wakefulness that the body follows. It is primarily regulated by light exposure, with daylight signalling the body to wake up and darkness signalling the body to produce melatonin, a hormone that promotes sleep. As we age, our eyes may let in less light, particularly the short-wave light that is important for regulating the circadian rhythm. Older adults may also spend less time outdoors and more time exposed to weak artificial light, which is less effective at controlling our sleep-wake cycle.
In addition to light exposure, physical activity and other external factors can also impact the circadian rhythm. Older adults may experience changes in their sleep patterns due to lifestyle factors or other age-related changes. They may also have more trouble adapting to new sleep rhythms, making it more difficult to adjust to changes in their schedule.
The endogenous secretion of melatonin, which promotes sleep, is reduced in older adults. This can contribute to sleep disruptions and daytime sleepiness. While melatonin replacement therapy has been suggested as a possible treatment, there is currently little consensus on the recommended dose or timing of administration, and it is not regulated by the Food and Drug Administration.
Circadian rhythm changes can have significant impacts on older adults, interfering with their daily activities and reducing their quality of life. Severe changes to the circadian rhythm may even be an early sign of Alzheimer's disease or other age-related pathologies.

Medication and health: Medication, illness, and pain can disrupt sleep
Sleep problems are common in older adults, and the quality of sleep tends to deteriorate with age. A healthy 70-year-old may wake up several times during the night, and this can be unrelated to any disease. However, medication, illness, and pain can also disrupt sleep.
Medication
Certain medications can interfere with sleep patterns, and older adults are more susceptible to these disruptions due to age-related alterations in sleep physiology. For example, tetrahydrocannabinol (THC), a psychoactive component of cannabis, can disrupt the sleep cycle. Even some sleep medications, when used frequently, can cause insomnia. Additionally, older adults taking certain medications for insomnia, such as hypnotics, benzodiazepines, and Z-drugs, may experience increased risks and side effects. It is always advisable to consult a doctor or a healthcare provider to review the medications and their potential impact on sleep.
Illness
Long-term or chronic illnesses can significantly impact sleep in older adults. Conditions such as heart failure, sleep apnea, untreated psychiatric illnesses, endocrine disorders, neurological disorders, chronic obstructive pulmonary disease, asthma, and gastroesophageal reflux disease can contribute to sleep disturbances. Additionally, mental health conditions like anxiety disorders, bipolar disorder, and depression are commonly associated with sleep problems.
Pain
The presence of pain during the night can significantly affect sleep quality in older adults. Musculoskeletal pain, in particular, has been linked to poor subjective sleep. The relationship between sleep and pain is bidirectional, meaning that as pain complaints become more prevalent with age, they can further disrupt sleep, creating a cycle that negatively impacts overall quality of life.

Lifestyle: Exercise, diet, stress, and social engagement impact sleep
Lifestyle choices, including exercise, diet, stress levels, and social engagement, can have a significant impact on sleep quality and duration.
Exercise
Regular exercise is beneficial for sleep. Engaging in physical activities such as walking, yoga, pilates, or moderate-intensity workouts can improve sleep quality. However, it is important to consider the intensity and timing of workouts. High-intensity exercises close to bedtime may delay sleep due to increased heart rate, while low-intensity workouts can promote relaxation and improve sleep.
Diet
A balanced diet that includes adequate amounts of carbohydrates, healthy fats, and proteins is essential for better sleep. Whole grains, high-fiber foods, and vitamins have been linked to improved sleep quality. On the other hand, diets low in fiber and high in saturated fat or sugar can impact sleep negatively. Additionally, consuming caffeine and alcohol within a few hours of bedtime can reduce sleep quality.
Stress
Stress is a common disruptor of sleep. High levels of stress can prolong the time it takes to fall asleep and cause sleep fragmentation. Stressful thoughts about responsibilities, work, family, or finances can interfere with sleep patterns. Managing stress through relaxation techniques, strategic planning, and offloading daytime responsibilities can help improve sleep.
Social Engagement
Socializing and engaging in group activities have been linked to improved sleep quality. Participating in novel, unfamiliar activities and having meaningful social connections can positively impact sleep. Social engagement provides mental and physical stimulation, which can help regulate sleep patterns and overall sleep quality.

Sleep environment: Bedroom comfort, light, and technology use affect sleep
Sleep is an essential part of our lives, and as we age, our sleep patterns and quality of sleep can change. Researchers estimate that between 40% and 70% of older adults experience chronic sleep issues, which can significantly impact their daily lives and overall well-being. Here are some ways to improve sleep by creating a comfortable bedroom environment, considering lighting, and managing technology use:
Bedroom Comfort:
Creating a comfortable sleep environment is crucial for a good night's rest. Here are some ways to enhance bedroom comfort:
- Temperature Control: Maintaining a cool and comfortable temperature is essential for promoting sleep. The National Sleep Foundation recommends a sleep environment of around 67 degrees Fahrenheit, although individual preferences may vary. Consider using climate control devices like fans, air conditioners, or heaters to maintain a suitable temperature. Additionally, investing in "high-tech" sheets and mattress toppers designed with temperature-regulating fabrics can help keep you cool and comfortable throughout the night.
- Air Quality: Improving the air quality in your bedroom can positively impact your sleep. Using an air purifier can help remove harmful contaminants such as pollen and dust, ensuring you breathe cleaner air during sleep.
- Comfortable Mattress and Pillows: A meticulously designed mattress with high-quality materials can provide cool comfort and support for a restful night's sleep. Smart pillows are also available, offering features like built-in speakers for streaming relaxing music or audiobooks, as well as temperature regulation to keep your pillow cool throughout the night.
Light:
Light plays a crucial role in regulating our sleep-wake cycles, known as circadian rhythms. Here are some ways to optimize lighting for better sleep:
- Natural Light Exposure: Aim for early morning sunlight exposure or equivalent indoor brightness. In contrast, avoid excessive light exposure at night, as it can disrupt your sleep.
- Minimize Blue Light Exposure: Blue light from electronic devices like phones, tablets, and TVs can stimulate your brain and disrupt your sleep. Use "night mode" settings or blue light filter glasses to reduce blue light exposure. Limiting screen time two to three hours before bedtime can also help.
- Bedroom Lighting: Make your bedroom as dark as possible at night. Use blackout curtains or electronically controlled window shades to block external light. When preparing for bed, keep the lighting dim, and consider using low-power lamps with warm color temperatures to promote relaxation.
- Smart Lighting Technology: Smart bulbs that gradually fade near bedtime and slowly brighten in the morning can help regulate your body's internal clock. These bulbs can even mimic the color of sunrise, providing a natural lighting experience.
Technology Use:
While technology can sometimes aid sleep, excessive or inappropriate use can be detrimental. Here are some tips to manage technology use:
- Remove Electronics: Consider removing phones, computers, and other electronic devices from your bedroom. This helps reduce the temptation to check emails or play games and it minimizes notifications and vibrations that can disturb your sleep.
- Limit Screen Time Before Bed: Avoid screens at least 30 minutes to two hours before bedtime. If you need to use devices, utilize “night mode” settings or blue light reduction applications to minimize their impact on your sleep.
- Utilize Sleep Trackers: Wearable or "nearable" sleep trackers can monitor sleep duration, quality, phases, and environmental factors like temperature and light exposure. This data can help you understand your sleep patterns and make necessary improvements.
