There are many reasons why older people may sleep a lot. Firstly, it is important to note that insomnia is the most common sleep disturbance in older adults, with up to 40-50% of those over 60 reporting disturbed sleep. Insomnia in older adults is associated with overall poor health and mental well-being. Moreover, older individuals often suffer from multiple medical problems, such as osteoarthritis, chronic obstructive pulmonary disease, congestive heart failure, and neurologic deficits, which can lead to difficulty with sleep initiation and maintenance. Additionally, mental health conditions such as depression, anxiety, and boredom are also common causes of excessive sleep in older adults. Furthermore, older adults often have to manage multiple medications, which may have side effects such as excessive sleepiness. Other causes include nutrient deficiencies, new medications, sleep disorders, and changes in the body's internal clock. It is important to consult a doctor to determine the underlying cause of excessive sleep in older adults and provide appropriate treatment or support.

What You'll Learn
Dementia
People with dementia may experience a complete reversal of their normal sleep patterns, staying awake all night and sleeping during the day. They may also experience a deterioration in the quality of their sleep as they get older, getting less deep or 'slow-wave' sleep, which is essential to keep the brain healthy and refreshed. Additionally, people with dementia may find it exhausting to perform simple tasks like communicating or eating, which can further contribute to their increased sleep.
There are several factors that can contribute to excessive sleep in people with dementia:
- Condition and Brain Changes: Vascular dementia and other types of dementia can directly affect sleep patterns, causing sleep issues at night and napping during the day. The damage to the brain associated with dementia can impact the areas responsible for regulating sleep and wakefulness, resulting in disrupted sleep-wake cycles.
- Coexisting Conditions: Conditions such as depression, which is common in those with vascular brain conditions, can cause persistent fatigue and changes in sleep patterns. Other coexisting conditions or side effects of medications can also contribute to excessive sleepiness.
- Medications: Certain medications can cause fatigue or sleepiness as a side effect, including antihistamines, antidepressants, antipsychotics, and some Parkinson's disease drugs. Polypharmacy, or taking multiple medications, can also increase the risk of drug interactions that may impact sleep.
- Sleep Disturbances: People with dementia may experience sleep disturbances such as insomnia or disrupted sleep-wake cycles, which can further contribute to excessive daytime sleepiness.
- Age and Health: Older adults may experience changes in their sleep patterns due to age-related factors or coexisting health conditions. Chronic pain, osteoarthritis, and neurological issues can impact sleep quality and contribute to excessive sleepiness.
It is important to consult a doctor if you notice significant changes in sleep patterns or excessive sleepiness in elderly individuals with dementia. They can help identify any underlying health problems, adjust medications, or suggest strategies to improve sleep quality and regulate sleep patterns.

Depression
Older adults with depression may find it difficult to fall asleep or stay asleep, and they may also experience frequent night-time awakenings or early morning awakenings. Depression can also cause changes in the body's internal clock, known as the suprachiasmatic nucleus (SCN), which is responsible for regulating circadian rhythms. These circadian rhythms influence when a person feels sleepy or alert, and as the SCN ages, it can disrupt sleep patterns, leading to fragmented sleep.
Additionally, older adults with depression may be taking medications that can interfere with sleep. Antidepressants can be effective in treating depression-related sleep disturbances, but they may also have side effects that impact sleep. It is important for older adults to consult with a healthcare provider before taking any sleep medications, as these can have risks and should not be used long-term.
Treating depression in older adults is crucial for overall health and well-being. Cognitive behavioural therapy, a form of counselling, can be effective in managing depression and improving sleep quality. Addressing depression and improving sleep habits can help enhance the quality of life for older adults and reduce the risk of other health complications associated with poor sleep.

Medication
Sleep difficulties become more common as people age. Insomnia is one of the most common sleep disorders in older adults, with people aged 60 and older being more susceptible to it. This can be attributed to several factors, including changes in our internal circadian clocks and sleep-wake cycles as we age, as well as the side effects of medications used to treat geriatric medical conditions.
When it comes to medication for sleep issues in older adults, it is important to proceed with caution. While sleeping pills and sleep medications can be effective, they also carry risks and side effects. Older adults should typically try non-drug treatments first, as there may be safer ways to improve sleep. Over-the-counter sleep medications often contain antihistamines, which can cause drowsiness, but they can also lead to side effects like constipation, diarrhea, muscle weakness, and digestive problems. Natural supplements such as melatonin and valerian are also available, but it is recommended to check with a healthcare provider before taking them.
Prescription sleep medications, such as benzodiazepines and non-benzodiazepines, can produce hypnotic effects and increase the risk of falling, tolerance, dependence, and withdrawal. Doctors should carefully consider the patient's other prescriptions to prevent negative drug interactions. Other prescription sleep medications include ramelteon, a melatonin agonist that interacts with natural hormones in the body to promote sleepiness, and suvorexant, which suppresses orexins, neuropeptides that cause sleep disturbances.
Antidepressants are also used to treat insomnia in older adults. Doxepin, at low doses, is a selective histamine antagonist that is FDA-approved for insomnia and has been shown to improve sleep parameters in older adults. Mirtazapine is another antidepressant that has been found to be effective in treating severe insomnia and anxiety associated with depression. Trazodone, a 5-HT2 receptor antagonist, has been shown to improve total sleep time and efficiency without serious side effects, even in patients with Alzheimer's dementia. However, caution should be exercised with patients with dementia or cognitive impairment, as adverse CNS effects may occur.
In summary, while medication can be an option for treating sleep issues in older adults, it should be approached with caution due to potential side effects and risks. Non-drug treatments should be considered first, and if medication is deemed necessary, it should be prescribed carefully, taking into account the patient's overall health and other medications. It is important to prioritize determining the underlying cause of the sleep disorder rather than just treating the symptoms.

Sleep disorders
The medications used to treat these various underlying medical problems can also cause disruptions in sleep. β-blockers, bronchodilators, and corticosteroids, for example, can all cause sleep disturbances. Polypharmacy is increasingly common among older adults, and the side effects of multiple medications interacting can cause excessive sleepiness.
Depression is a common cause of sleep problems in people of all ages. In older adults, this can be triggered by extreme boredom, loss of a sense of purpose, medication changes, the death of loved ones, or loneliness. Other mental disorders or medical conditions that may cause insomnia include anxiety disorders, bipolar disorder, alcoholism, and thyroid disease.
Dementia, especially in its later stages, can cause people to sleep a lot during the day and night. This can be distressing for family and friends, who may worry that something is wrong. However, excessive sleepiness during the day does not always mean death is close.
If an elderly person is sleeping a lot, it is important to ensure they are still getting the personal hygiene, hydration, medications, and nutrition they need. They should not be in the same position for too long, or bed sores and other health problems may arise.

Lifestyle changes
While occasional sleep problems are common at any age, disturbed sleep, waking up tired every day, and other symptoms of insomnia are not a normal part of aging. Sleep is essential for both physical and emotional health, and insufficient sleep can lead to serious health problems, including an increased risk of cardiovascular disease, diabetes, weight issues, and breast cancer in women.
If an elderly person is sleeping a lot, it could be due to underlying health problems, medication, or lifestyle factors. Here are some lifestyle changes that could help improve sleep:
- Exercise: Regular exercise can help improve sleep, but it should not be done within three hours of bedtime.
- Sunlight: Getting sunlight during the day can help regulate the body's internal clock, making it easier to fall asleep at night.
- Bedtime routine: Establish a bedtime routine that promotes relaxation and prepares the body for sleep. This could include taking a warm bath, drinking herbal tea, or practicing meditation or deep breathing.
- Sleep schedule: Maintain a consistent sleep schedule by going to bed and waking up at the same time each day, even on weekends. This helps to regulate the body's internal clock and improve sleep quality.
- Bedroom environment: Ensure the bedroom is comfortable, dark, quiet, and conducive to sleep. Consider using earplugs, eye masks, or white noise machines to block out distractions.
- Limit caffeine and alcohol: Caffeine and alcohol can disrupt sleep. Limit caffeine intake after noon and avoid alcohol close to bedtime, as it can disrupt sleep later in the night.
- Screen time: Avoid screens, such as televisions, computers, and phones, for at least an hour before bedtime, as the blue light emitted by these devices can interfere with sleep.
- Comfortable bed: Invest in a comfortable mattress, pillows, and bedding that support the body and promote sleep.
- Sleep position: Use an adjustable bed base to accommodate different sleeping positions and relieve pain or discomfort.
- Sleep diary: Keep a sleep diary to track sleep patterns, caffeine and alcohol intake, exercise, and any lifestyle changes. This can help identify patterns and potential triggers for sleep disturbances.
- Stress management: Stress and anxiety can disrupt sleep. Practice relaxation techniques, such as deep breathing or meditation, and seek support from family or a counselor to manage stress effectively.
- Healthy diet: Eat a balanced diet and avoid heavy, sugary, or spicy foods close to bedtime, as they can disrupt sleep. Limit fluid intake before bed to prevent frequent bathroom trips.
It is important to consult a doctor if sleep problems persist or if there are concerns about underlying health conditions or medication interactions.
