Sleep architecture changes: Older adults spend more time in lighter sleep stages and less time in deeper sleep
As people age, they experience changes in their sleep architecture, or how they cycle through the different stages of sleep. Older adults tend to spend more time in the early, lighter stages of sleep and less time in the later, deeper stages of sleep. This shift may be a result of changes in the body's internal clock, which is controlled by the suprachiasmatic nucleus (SCN) located in the hypothalamus region of the brain. The SCN regulates 24-hour daily cycles, known as circadian rhythms, which influence sleepiness and alertness. As the SCN ages, it can cause a phase advance, resulting in older adults feeling tired earlier in the afternoon and waking up earlier in the morning.
The shift in sleep architecture can contribute to older adults waking up more frequently during the night and experiencing more fragmented and less restful sleep. This can lead to excessive daytime sleepiness, with older adults taking more naps during the day to compensate for lost sleep at night. However, extended napping and napping later in the day can disrupt nighttime sleep, creating a cycle of sleep disruption. Additionally, older adults may experience longer recovery times from changes in their sleep schedules due to alterations in their circadian rhythms.
The decrease in deeper sleep stages among older adults can have implications for brain health. Deep or 'slow-wave' sleep is important for keeping the brain healthy and refreshed. As such, the reduction in this type of sleep may impact cognitive function and overall brain health in older adults.
There are several factors that can contribute to changes in sleep architecture and excessive daytime sleepiness in older adults. One factor is the development of chronic health conditions and age-related changes that limit their activities and impact their quality of life. Boredom and a lack of stimulation can lead to excessive napping during the day. Additionally, older adults may experience more aches and pains, as well as a need to use the restroom more frequently, disrupting their sleep at night.
Medications and medical treatments can also play a role in sleep disturbances among older adults. As metabolism and fat concentration change with age, older adults may become more vulnerable to the side effects of certain medications, including fatigue. Medical treatments, such as chemotherapy or radiation, can also leave seniors feeling exhausted. Furthermore, older adults with dementia may experience significant disruptions to their sleep-wake cycles, resulting in daytime sleepiness and nighttime wakefulness.

Circadian rhythm shifts: Age-related changes in the body's internal clock can disrupt sleep patterns
Circadian rhythms are 24-hour cycles that influence when people get hungry, when the body releases certain hormones, and when a person feels sleepy or alert. This rhythm is controlled by a part of the brain called the hypothalamus, which is made up of around 20,000 cells that form the suprachiasmatic nucleus (SCN).
As people age, their circadian rhythms shift forward in time, which is called a phase advance. Older adults may experience this as getting tired earlier in the afternoon and waking up earlier in the morning. Research also shows that the circadian rhythm in older adults is more delicate, leading to fragmented sleep if they don't sleep within certain times.
Additionally, older adults spend more time in the early, lighter stages of sleep and less time in the deeper, later stages. These shifts contribute to older people waking up more frequently during the night and having more fragmented and less restful sleep. They may also experience changes in their sleep architecture, or how they cycle through the different stages of sleep.
The circadian rhythm can be influenced by external factors such as daylight exposure and physical activity. For example, spending more time in daylight can help older adults sleep better at night. Conversely, reduced exposure to bright light has been associated with nighttime sleep fragmentation and circadian rhythm sleep disorders.
As people age, their bodies also become more sensitive to changes in their sleep schedules, such as those caused by daylight saving time or jet lag. This can make it more challenging for older individuals to adjust to sudden shifts in their sleep patterns.

Daytime napping: Older adults may nap more, impacting their nighttime sleep and causing daytime sleepiness
As people age, their bodies experience various changes that can affect their sleep patterns. One notable change is the shift in their body's circadian rhythms, also known as the internal clock, which is controlled by the suprachiasmatic nucleus (SCN) in the brain. This shift can cause older adults to feel tired earlier in the afternoon and wake up earlier in the morning, resulting in a phase advance in their sleep-wake cycle. Additionally, older adults may spend more time in the lighter stages of sleep and less time in the deeper, rapid-eye-movement (REM) sleep, leading to more fragmented and less restful sleep.
Daytime napping is a common occurrence among older adults, with research estimating that about 25% of them take naps, compared to only 8% of younger adults. While short daytime naps may be beneficial, extended napping and napping later in the day can disrupt nighttime sleep and create sleep disturbances. This is because napping too late in the day may affect the ability of older adults to fall asleep at bedtime, leading to a vicious cycle of daytime sleepiness and nighttime wakefulness.
There are several reasons why older adults may nap more during the day. One reason could be to compensate for the decline in the quality of their nighttime sleep. As mentioned earlier, older adults experience more fragmented sleep and spend less time in the deeper stages of sleep, resulting in less restful sleep. They may also wake up frequently during the night due to various reasons such as achy joints, the need to use the restroom, or underlying health conditions.
Additionally, older adults may experience excessive daytime sleepiness due to various health issues, medications, or mood disorders. Certain medications can cause fatigue as a side effect, and older adults may be more vulnerable to these side effects due to changes in their body's metabolism and fat concentration. Health issues such as sleep apnea, depression, and dementia can also contribute to increased napping during the day. For example, people with dementia may experience a complete reversal of their normal sleep patterns, staying up all night and sleeping during the day.
To improve sleep patterns in older adults, it is recommended to establish a solid sleep schedule with consistent bedtimes and wake-up times, even on weekends and during travel. Avoiding naps in the afternoon or evening, minimizing screen time before bed, and engaging in regular physical activity can also help reduce daytime napping and improve nighttime sleep quality. Seeking medical advice is also important to address any underlying health issues that may be contributing to excessive daytime sleepiness.

Health conditions: Chronic health issues and medications may contribute to excessive sleepiness in older adults
It is a common misconception that older adults require less sleep than younger individuals. However, this is not the case, as older adults often experience changes in the quality and duration of their sleep. While some older adults may experience no significant disruptions, others may complain about getting less sleep and having worse sleep quality.
Several health conditions may cause sleep problems in older adults, including:
- Neurodegenerative disorders such as Parkinson's disease, which becomes more prevalent with age. According to the Parkinson's Foundation, up to 40% of people with Parkinson's disease also have obstructive sleep apnea.
- Alzheimer's disease, which may cause daytime drowsiness and difficulty staying asleep at night.
- Chronic pain, such as arthritis, which can lead to inadequate rest.
- Cardiovascular disease, which can result in shorter sleep duration and an increased risk of death.
- Neurological conditions like multiple sclerosis and traumatic brain injuries.
- Gastrointestinal conditions, including gastroesophageal reflux disease (GERD) and irritable bowel syndrome (IBS).
- Lung or respiratory conditions.
Additionally, older adults may experience an increase in mental and physical health conditions that can contribute to fragmented sleep. Sleep disturbances can lead to a decrease in sleep quality and quantity, developing into chronic sleep issues if left unaddressed.
Medications can also play a role in excessive sleepiness among older adults. While medications such as benzodiazepines are commonly prescribed for sleep disorders, they are not recommended for insomnia in older adults. Benzodiazepines can increase the risk of cognitive and psychomotor impairments, falls, fractures, and motor vehicle accidents. Other medications with hypnotic effects, such as non-benzodiazepines (Z-drugs), also carry risks of tolerance, dependence, and withdrawal, and can increase the risk of falling. It is crucial to carefully consider and prescribe insomnia medications for older adults, taking into account their overall health and other prescriptions to prevent negative drug interactions.

Mental health: Depression, dementia, and boredom can lead to increased sleep and negatively impact sleep quality
As people age, they experience changes in the quality and duration of their sleep. This is due to changes in the body's internal clock, which is located in a part of the brain called the hypothalamus. This internal clock controls the body's circadian rhythms, which are 24-hour daily cycles that influence when a person feels sleepy or alert. A shift in these circadian rhythms, known as a phase advance, can cause older adults to get tired earlier in the afternoon and wake up earlier in the morning.
Various factors can contribute to mental health issues such as depression, dementia, and boredom, which can further impact sleep quality. Depression is a common mental health disorder among older adults, with a global prevalence of 13.3% in older individuals, and it is often associated with changes in sleep patterns. Untreated depression can lead to daytime sleepiness, and certain antidepressant medications can also have sleepiness as a side effect.
Dementia can also affect sleep patterns, as the physical changes in the brain associated with dementia can impact sleep regulation. People with dementia may experience difficulties sleeping at night and may sleep more during the day. They may struggle with falling asleep or experience frequent nighttime awakenings, leading to fragmented and less restful sleep. Additionally, the body clock of a person with dementia may become damaged, making it harder for them to feel awake and alert during the day.
Boredom is another factor that can contribute to excessive daytime sleeping in older adults. As people age, they may face limitations in their physical abilities, vision impairments, or a lack of engaging activities, leading to boredom and an increased tendency to nap during the day. This can create a cycle of napping that disrupts nighttime sleep and further impacts overall sleep quality.
It is important to address these mental health issues and boredom to improve sleep patterns and overall well-being in older adults. Seeking medical help, establishing a healthy sleep routine, and finding stimulating activities or social engagement can help mitigate the negative impact of depression, dementia, and boredom on sleep quality.
