As we age, sleep patterns naturally evolve, and many seniors find themselves struggling with sleep quality.
Studies indicate that up to 50% of older adults report symptoms of insomnia, making it one of the most common sleep issues among seniors. While the recommended amount of sleep for seniors is 7-8 hours, the actual sleep experience often involves disruptions that leave them feeling less rested, despite spending more time in bed.

How Much Sleep Do Seniors Actually Get?
The National Sleep Foundation recommends 7-8 hours of sleep for adults over 65, but data suggests that seniors actually get more sleep than expected. According to surveys, adults 65 and older sleep an average of 8 to 9 hours per night, often exceeding the recommended amount.
However, longer sleep duration does not always equate to better sleep quality. Many seniors experience fragmented sleep, frequent wake-ups, and less deep sleep, which affects how rested they feel despite spending more time in bed.
In addition, daytime naps can contribute to this disrupted sleep pattern, as they may reduce the drive to sleep deeply at night. While naps can offer short-term relief, managing nap timing and duration is important to avoid any sleep disorders
How Aging Affects Sleep Patterns
As we age, the way we sleep changes, not just in duration but in quality. Older adults may get 7 to 9 hours of sleep each night, but that doesn’t mean it’s restful. Many people assume that we need less sleep as we get older, but in reality, the changes in sleep patterns are more about lighter, fragmented sleep rather than a reduced need for rest.
You may wonder why older people sleep less. It’s because sleep becomes lighter and more fragmented, with fewer deep sleep cycles and more frequent wake-ups throughout the night, making it harder to feel fully rested.
- Decline in Deep Sleep: Young adults spend 80 to 100 minutes per night in slow-wave sleep, the most restorative stage of sleep. However, by age 60, this drops drastically to less than 20 minutes per night.
- More Frequent Night Wakings: Older adults wake up an average of 3 to 4 times per night. They also tend to be more aware of these awakenings, making it feel like they’re getting even less sleep.
- Reduction in REM Sleep: As people age, the amount of time spent in REM sleep decreases. Since REM sleep plays a key role in memory consolidation and cognitive function, this decline can contribute to forgetfulness, slower mental processing, and difficulty retaining new information.
- Melatonin Production Drops: By age 50, melatonin levels decrease by 50%, making it harder to fall and stay asleep.
Common Sleep Problems in Older Adults
1. Insomnia
- Up to 50% of older adults report symptoms of insomnia, making it one of the most widespread sleep problems in seniors.
2. Sleep Apnea
- 32% of people over 65 have some form of sleep apnea, a condition that causes breathing to repeatedly stop and start during sleep.
- Among people with Parkinson’s disease, 40% experience obstructive sleep apnea, which further worsens their sleep and overall health.
- Sleep apnea is linked to an increased risk of heart disease, stroke, and cognitive impairment if left untreated.
3. Restless Leg Syndrome (RLS) and Periodic Limb Movement Disorder (PLMD)
- RLS causes an overwhelming urge to move the legs during rest, affecting middle-aged and older adults more frequently and for longer durations.
- PLMD leads to involuntary limb movements during sleep, and while its exact cause is unknown, research suggests it originates in the central nervous system.
4. Narcolepsy and Hypersomnia
- While less common than insomnia or sleep apnea, conditions like narcolepsy (excessive daytime sleepiness) and hypersomnia (excessive sleep duration) can also impact seniors, leading to persistent fatigue and disrupted sleep patterns.
Effects of Sleep Changes in Older Adults
Sleep difficulties can have serious consequences. Chronic insomnia is linked to a higher risk of car accidents, depression, and cognitive decline.
Many older adults wake up frequently throughout the night, which makes them feel sleep-deprived even if they’re technically getting enough hours in bed.
Lack of quality sleep can also increase the risk of serious health issues:
- Cognitive decline: Older adults who sleep less than 4.5 hours or more than 6.5 hours per night and experience frequent sleep disruptions are at greater risk of cognitive decline.
- Dementia risk: Those who consistently get 5 hours of sleep per night are 30% more likely to develop dementia.
- High blood pressure: Sleeping less than 6 hours per night increases the risk of hypertension by 20% to 32% compared to those who get 7 to 8 hours.
Treatments for Sleep Problems
Addressing sleep problems in older adults often requires a combination of lifestyle changes, medical treatments, and targeted therapies.
With up to 50% of seniors experiencing insomnia symptoms, finding the right approach is key to improving sleep quality.
Melatonin and Sleep Aids
Many individuals turn to melatonin supplements to regulate their sleep cycles. Melatonin use has surged by 425% between 1999 and 2018, making it the most popular sleep supplement today. 49% of adults report using melatonin to improve their sleep.
While melatonin can help some seniors, excessive or long-term use may reduce natural melatonin production, leading to dependency.
Cognitive Behavioral Therapy for Insomnia (CBT-I)
CBT-I is considered the most effective long-term treatment for insomnia in older adults.
Studies show that 70-80% of people with chronic insomnia see improvement with CBT-I. This therapy helps retrain the brain by addressing negative thoughts and behaviors that interfere with sleep.
CPAP Therapy for Sleep Apnea
32% of seniors have sleep apnea, yet many cases go undiagnosed. Continuous Positive Airway Pressure (CPAP) machines reduce apnea episodes, improving both sleep quality and overall health. Treating sleep apnea lowers the risk of heart disease, stroke, and cognitive decline.
Lifestyle Changes for Better Sleep
Regular physical activity significantly improves sleep efficiency. Research shows that persistently active seniors are 55% more likely to be normal sleepers and 29% less likely to sleep six hours or less.
Those who become active later in life are still 21% more likely to be normal sleepers compared to those who remain inactive.
Moreover, avoiding caffeine and alcohol 4-6 hours before bed can prevent disruptions and improve sleep quality.
Practicing good sleep hygiene, such as keeping a consistent sleep schedule or choosing the right mattress, will help regulate circadian rhythms, which naturally shift with age and cause earlier wake-up times. Furthermore, improving sleep habits, including creating a calming bedtime routine, can improve health conditions.
Bottom Line
In conclusion, while seniors are recommended to get 7-8 hours of sleep, many actually sleep 8-9 hours, though this doesn’t guarantee restful sleep. Up to 50% of older adults report insomnia, and 32% suffer from sleep apnea, which can lead to serious health risks, including cognitive decline and high blood pressure.
Understanding why do elderly have trouble sleeping at night is crucial, as addressing these challenges with treatments like CBT-I, CPAP therapy, and lifestyle changes can significantly improve sleep quality and overall well-being for seniors.
