Why Do Seniors Sleep So Much? Understanding Causes & Solutions 

Why Do Old People Sleep So Much?

Sleep patterns change with age, leading many older adults to sleep more during the day but struggle with disrupted sleep at night. While total sleep time often decreases, frequent awakenings can make rest feel less refreshing.

Aging also reduces the time spent in deep sleep (stage three non-REM) and REM sleep, both of which are essential for brain recovery, memory, and learning. As a result, seniors may wake up feeling less rested, even if they’ve spent enough time in bed.

Falling asleep can also take longer, but research shows that once awake, older adults return to sleep just as easily as younger people. Still, 23% of seniors (average age 84) report excessive daytime sleepiness, often due to poor nighttime sleep. 

To make up for this, 20-60% take daytime naps, though napping too much can further disrupt nighttime rest.

How Much Sleep Do Seniors Need?

Older adults need 7–8 hours of sleep per night, but many struggle to get quality rest. For caregivers, understanding the recommended sleep duration can help distinguish normal aging from potential sleep issues.

Common Reasons Seniors Sleep More

Aging affects sleep in many ways, from shifting internal clocks to health conditions that make resting less restorative. Here are some of the most common reasons seniors tend to sleep more:

Health Problems

Many seniors experience chronic health conditions that interfere with sleep, leading to frequent nighttime awakenings and excessive daytime sleepiness. 

Some of the most common health-related sleep disruptors include:

• Insomnia: Studies show that insomnia is the most common sleep disturbance in older adults, with 40%–50% of those over 60 reporting difficulty sleeping and an annual incidence rate of 5% in adults over 65. 
• Arthritis: Joint pain and stiffness make it difficult to find a comfortable sleeping position, leading to fragmented sleep and increased fatigue.
• Restless leg syndrome: An irresistible urge to move the legs, affecting about 10% of all adults and up to 25% of those over 65, makes it hard to fall asleep and stay asleep.
• Neurodegenerative disorders: Medical conditions like dementia, Alzheimer’s disease, and Parkinson’s disease alter brain function, leading to irregular sleep patterns and increased daytime drowsiness.
• Heart disease: The incidence of cardiovascular disease increases with age, affecting approximately 40% of adults aged 40–59, 75% of those aged 60–79, and 86% of those over 80. Heart conditions can lead to poor circulation, breathing difficulties, and restless sleep.
• Nocturia: Frequent urination at night affects more than 50% of older adults, leading to multiple nighttime awakenings and less restorative sleep.
• Diabetes: Fluctuating blood sugar levels and neuropathy or nerve pain can cause nighttime discomfort and frequent wake-ups.
• Sleep apnea: A condition where breathing repeatedly stops and starts during sleep. Its side effects include loud snoring, daytime fatigue, and an increased risk of heart disease and high blood pressure.

Shifting Sleep Schedule

As we age, our body’s internal clock (circadian rhythm) changes, making us feel sleepy earlier in the evening and wake up earlier in the morning. This shift can be more noticeable with external disruptions like daylight saving time or jet lag. 

While younger adults can adapt more easily, older individuals often struggle to adjust, leading to earlier bedtimes, earlier wake-ups, and, sometimes, more daytime sleep.

Depression

More than 1 in 10 older adults experience depression. Sleep problems are closely linked to depression, which is more common in seniors due to aging, social isolation, and the loss of loved ones. 

Depression can cause both insomnia and excessive sleepiness, making some seniors sleep much more than usual. Unlike regular tiredness, this sleep doesn’t feel refreshing, leaving them exhausted even after resting.

Boredom

Many seniors experience a lack of engagement in daily life, especially after retirement. With fewer hobbies, social outings, and entertainment options, boredom becomes more common. 

Without regular physical activity or stimulating activities, some seniors may take a nap out of habit rather than need, gradually increasing their overall sleep time. This shift can affect their sleep patterns and overall quality of life.

How to Improve Sleep Quality for Seniors

Lack of quality sleep can increase the risk of memory issues, depression, and heart disease. 

Here’s how to improve sleep and wake up feeling refreshed.

• Stick to a regular sleep schedule: About 40% of older adults struggle with falling or staying asleep. Going to bed and waking up at the same time daily can help regulate your body’s internal clock. As soon as you wake up, get out of bed and start your day. Sleeping and waking at different times can throw off your sleep cycle.
• Limit alcohol before bed: While alcohol may help some people fall asleep, studies show it reduces sleep quality and increases nighttime trips to the bathroom. Avoid drinking alcohol within four hours of bedtime to prevent disruptions.
• Cut back on evening caffeine: Caffeine stays in your system for hours. Research shows that consuming caffeine even 6 hours before bed can reduce sleep time by more than 1 hour. Avoid coffee, tea, and soda afternoon for better sleep.
• Eat regular meals: Seniors who eat irregularly are more likely to have poor sleep quality. Stick to three balanced meals a day and light snacks if needed. Avoid heavy meals before bed, as digestion problems can interfere with sleep.
• Reduce fluid intake at night: Nearly 50% of older adults wake up at night to use the bathroom. To prevent frequent trips, drink most of your fluids in the morning and limit liquids before bed. If you have heart or circulation issues, consult your doctor first.
• Avoid screens before bed: Blue light from screens can suppress melatonin, the sleep hormone, and delay sleep by up to 90 minutes. Avoid TV, social media, or reading stressful news before bed. Use your bed only for sleep, relaxation, and intimacy to strengthen your body’s sleep signals.
• Create a comfortable sleep environment: Studies suggest that sleeping in a dark, quiet, and cool environment improves sleep quality by up to 80%. Keep your room at a comfortable temperature and upgrade to a supportive mattress if needed.
• Exercise during the day: Studies show that within just 4 weeks, people with chronic insomnia who start regular exercise fall asleep 13 minutes faster and stay asleep 18 minutes longer. Light aerobic activities like walking or biking in the morning can significantly improve sleep. However, avoid intense workouts before bed, as they may keep you awake.
• Get sunlight during the day: Natural daylight helps reset your body’s internal clock. Seniors exposed to sunlight daily tend to fall asleep faster and sleep more soundly. Spend time outdoors or keep your blinds open during the day.
• Manage stress before bed: Anxiety and racing thoughts can make it harder to sleep. Writing down tasks before bed can help clear your mind and improve sleep. If stress keeps you up regularly, speaking with a therapist may provide helpful solutions.

Bottom Line

Sleep patterns change with age, and more than 50% of older adults report sleep disturbances. Factors like health conditions, depression, and boredom contribute to excessive sleep or poor-quality rest. 

Nearly 40%–50% of seniors over 60 struggle with insomnia, while up to 60% take daytime naps to compensate for nighttime disruptions. Regular exercise can help, with studies showing that in just four weeks, those with chronic insomnia fall asleep and stay asleep 18 minutes longer. 

Creating a consistent sleep routine, limiting caffeine and alcohol, and improving sleep environments can significantly enhance sleep quality for seniors.
