Sleep patterns change as we age, and older adults may experience changes in the quality and duration of their sleep. While it is a common misconception that older adults require less sleep, many older adults struggle to get the sleep they need. Sleep disorders in older adults can involve disrupted sleep patterns, problems falling or staying asleep, excessive sleep, or abnormal behaviours with sleep. This can be caused by a variety of factors, including changes in the body's internal clock, long-term health conditions, medications, mental health, lifestyle habits, and more. Understanding the underlying reasons for sleep disturbances in older adults is crucial for improving their sleep quality and overall well-being.

Hormonal changes
As we age, our bodies produce less melatonin, a hormone that is usually secreted in response to darkness, aiding sleep by coordinating our circadian rhythms. This decrease in melatonin production is one of the reasons why older people tend to experience changes in the quality and duration of their sleep.
Hormones such as estrogen and progesterone, which are the two major female hormones, also play a significant role in sleep quality. Women with polycystic ovary syndrome (PCOS) tend to have irregular periods, higher testosterone levels, and lower progesterone levels. These hormonal irregularities can exacerbate sleep difficulties. Research also suggests that lower levels of progesterone can make women more irritable and less able to relax, which can negatively impact sleep.
Additionally, menopause can cause significant hormonal changes, leading to night sweats and hot flashes that can disrupt sleep. The loss of reproductive hormones during menopause may also contribute to the development of sleep apnea, a condition where breathing briefly stops during sleep. Postmenopausal women are two to three times more likely to experience sleep apnea compared to premenopausal women.
Furthermore, older individuals taking multiple medications should be cautious as drug interactions can magnify side effects like drowsiness. Certain medications for conditions such as anxiety, depression, insomnia, and allergies can cause excessive sleepiness.
While hormonal changes are a significant factor in sleep disturbances among older adults, it is important to note that lifestyle changes, stress, anxiety, and the presence of multiple health conditions can also contribute to sleep issues in this population.

Medication side effects
Older adults commonly experience sleep disorders. While sleeping pills and medication can help, they also come with side effects and risks.
Diphenhydramine
Diphenhydramine is an antihistamine that blocks H1 receptors in the brain, which are crucial for wake-promoting effects. It is the active ingredient in many over-the-counter sleep aids, such as Advil PM, Tylenol PM, ZZZQuil, and Benadryl. While it can help with sleepiness, it has been linked to an increased risk of cognitive decline, confusion, urinary retention, constipation, and next-day grogginess in older adults. It can also cause decreased reaction times and dizziness, leading to a higher risk of falls and accidents, especially at night. The American Academy of Sleep Medicine does not recommend diphenhydramine as a first-line treatment for chronic insomnia.
Melatonin and Valerian
Melatonin is a hormone that promotes sleep and is often taken as a supplement. Valerian is an herb that has a calming effect on the nervous system and is also taken as a supplement. While these are natural remedies, they can interfere with other medications or make health conditions worse. It is always best to check with a healthcare provider before taking them.
Prescription Sleeping Pills
Prescription sleeping pills, such as benzodiazepines, carry more risks than over-the-counter options. Benzodiazepines can impair mental and physical function in older adults, increasing the risk of falls and confusion. When combined with other medications, especially painkillers, mood stabilizers, or anxiety medications, they can suppress breathing and lead to respiratory depression. Sleeping pills can also cause constipation, muscle weakness, and a "hangover" effect the next day, with people feeling drowsy and experiencing muddled thinking.
Additionally, sleeping pills can lead to dependence, and if not used correctly, they can make sleep problems worse over time. They are not recommended for long-term use, and older adults should try non-drug treatments first, such as exercise and relaxation techniques.
Dementia
For people with dementia, sleep medication can be especially dangerous. It can cause dizziness and an increased risk of falls, and it is only prescribed for very short-term use when severe sleep problems are present. Drugs like donepezil, rivastigmine, and galantamine, which are used to treat dementia symptoms, can also cause insomnia as a side effect.

Lifestyle factors
Social isolation and significant life changes are other lifestyle factors that can impact sleep. These experiences can increase stress and anxiety, which are commonly associated with sleep issues. Additionally, older adults who experience social isolation may have reduced opportunities for physical activity and social interaction, which can negatively affect their sleep quality. Engaging in physical activities, social interactions, and mental stimulation can help improve sleep patterns and overall well-being in older adults.
Hormonal changes also contribute to sleep disturbances in older adults. The body's production of melatonin, a hormone that promotes sleep and regulates circadian rhythms, decreases with age. This reduction in melatonin can disrupt sleep patterns, making it challenging for older adults to fall and stay asleep.
Furthermore, certain lifestyle choices, such as staying up late and not maintaining a consistent sleep schedule, can lead to sleep deprivation in older adults. This deprivation can manifest as insomnia, which is a common sleep disturbance in this age group. It is important for older adults to prioritize sleep and practice good sleep hygiene to ensure they are getting adequate rest.
Additionally, older adults may experience sleep apnea, which is more prevalent in this age group due to their bodies producing less oxygen during sleep. This condition can lead to heavy snoring and interrupted sleep, resulting in increased sleep requirements. Sleep apnea can also be a symptom of underlying health issues, such as cardiovascular disease and diabetes, or a side effect of certain medications.

Dementia and other health conditions
Sleep disturbances are common in older adults. This can be due to changes in the body's internal clock, which is located in the hypothalamus and controls our 24-hour circadian rhythms. As we age, our bodies also produce less melatonin, a hormone that promotes sleep by coordinating these circadian rhythms.
There is a complicated relationship between sleep and dementia. People living with dementia often experience poor sleep, but it is unclear whether this is a risk factor for the disease. Some researchers believe that both theories—that poor sleep increases dementia risk and that early dementia causes poor sleep—could be true, and the relationship is circular.
Studies have shown that individuals who sleep fewer than five hours per night are twice as likely to develop dementia. Consistently sleeping six hours or less at age 50, 60, and 70 was associated with a 30% increase in dementia risk. However, it is not yet fully understood why inadequate sleep increases dementia risk. One theory suggests that during sleep, brain cells and their connections shrink, creating more space between them so that substances like the beta-amyloid protein, which is involved in Alzheimer's disease, can be flushed away. Therefore, a lack of sleep may result in a higher concentration of this toxic protein.
Different types of dementia are associated with different sleep problems. For example, rapid eye movement sleep behaviour disorder (RBD), where people act out their dreams or talk in their sleep, is linked to Dementia with Lewy bodies and Parkinson's disease. Sleep disturbances are also common in Alzheimer's disease, with patients often waking up frequently during the night and finding it difficult to fall back asleep. This may be due to the amyloid protein, which builds up in Alzheimer's, disrupting the sleep-wake cycle.
Medications for conditions like anxiety, depression, insomnia, chronic pain, and dementia can also cause excessive sleepiness in older individuals. Older adults may metabolize medications differently, making them more susceptible to adverse effects.
Excessive sleeping in older individuals with serious medical conditions could indicate a decline in health, so it is important to ensure they are still receiving proper nutrition, personal care, and medications. A solid routine can be beneficial for managing dementia behaviors. Providing opportunities for social interaction, mental stimulation, and physical activity can also improve an older adult's quality of life and sleep.

Circadian rhythm changes
One key factor contributing to circadian rhythm changes is the decrease in melatonin production. Melatonin is a hormone that helps promote sleep and is usually secreted in response to darkness. With age, the body produces less melatonin, which can disrupt the coordination of circadian rhythms and make it more challenging to fall and stay asleep.
Additionally, older adults may experience a natural slowdown in energy production, resulting in decreased physical activity and engagement during the day. This reduced activity can further impact their sleep at night. Studies have shown that boredom and a lack of engagement during the day can contribute to excessive sleep in older adults. When individuals are more involved in life and have various activities to occupy their time, they tend to sleep better at night.
Furthermore, the quality of sleep tends to change as people age. Older adults may experience more fragmented sleep with frequent awakenings, resulting in less deep or "slow-wave" sleep. This reduction in deep sleep can impact brain health and leave them feeling less rested, even after a full night's sleep.
To mitigate the effects of circadian rhythm changes, older adults can benefit from establishing a solid daily routine. Maintaining a consistent sleep schedule, reducing distractions in the bedroom, and limiting substances that interfere with sleep, such as caffeine and alcohol, can all help improve sleep quality. Additionally, regular exercise and social interaction can enhance overall well-being and contribute to better sleep patterns.
