How Aging Affects Your Sleep Quality and Quantity

On average, the amount and vitality replenished through sleep in older adults may not match that of younger adults. Beyond the age of 80, this situation becomes particularly severe, potentially impacting health significantly, though it might go unnoticed.

The Role of Deep Sleep in Restoring Your Body and Mind

Deep sleep is essential for maintaining your physical and mental health, but it declines as you get older. During deep sleep, your body and brain undergo various processes that help you:

Body	Brain
- Balance your blood pressure, heart rate, and glucose levels - Strengthen your immune system and fight infections - Repair your muscles and tissues and prevent inflammation	- Consolidate and store your memories and learned information - Enhance your creativity and problem-solving skills - Clear out toxins and waste products from your brain cells

However, aging affects the quality and quantity of deep sleep. Your brain waves become less powerful and synchronized during deep sleep, and you spend less time in this stage. According to a study by Mander et al. (2015), people in their thirties and forties have 60-70% less deep sleep than teenagers, and this reduction reaches 80-90% by the age of 70. This means that you may not get enough deep sleep to restore your body and mind fully.

How Sleep Becomes More Disrupted and Fragmented with Age

One of the challenges of aging is maintaining uninterrupted and restful sleep throughout the night. Many older adults experience frequent awakenings due to various reasons, such as physical discomfort, bladder problems, or environmental noise. These interruptions can reduce the quality and quantity of sleep, leading to daytime fatigue, mood changes, and cognitive decline.

Sleep Efficiency	Definition	Example
High	More than 90% of the time in bed is spent sleeping	If you sleep for 9 hours in a 10-hour period, your sleep efficiency is 90%
Low	Less than 80% of the time in bed is spent sleeping	If you sleep for 6 hours in a 10-hour period, your sleep efficiency is 60%

Sleep efficiency is a measure of how well you sleep during the night. It is calculated by dividing the total sleep time by the total time in bed. A high sleep efficiency indicates that you fall asleep quickly and stay asleep for most of the night. A low sleep efficiency indicates that you have trouble falling asleep or staying asleep, or that you spend too much time in bed awake.

According to a study by Ohayon et al. (2004), the average sleep efficiency of older adults (65 years and older) is 77.5%, which is below the optimal level of 90% or higher. This means that older adults may lose more than two hours of sleep every night, even if they spend enough time in bed. This can have negative effects on their health and well-being, as well as their ability to function during the day.

Some of the factors that can disrupt and fragment sleep in older adults are:

Bodily pain. Chronic pain from conditions such as arthritis, osteoporosis, or neuropathy can make it hard to fall asleep or stay asleep. Pain can also cause restless leg syndrome, a condition that causes unpleasant sensations and urges to move the legs during the night.
Bladder problems. Older adults may have to get up more often to urinate during the night, due to reduced bladder capacity, prostate enlargement, or urinary tract infections. This can interrupt the sleep cycle and make it harder to fall back asleep.
Environmental noise. Older adults may be more sensitive to noise, such as traffic, neighbors, or pets, that can disturb their sleep. They may also have hearing loss, which can affect their perception of sound and make them more prone to tinnitus, a ringing or buzzing in the ears that can interfere with sleep.

Fortunately, there are some strategies that can help older adults improve their sleep quality and reduce the impact of these factors. These include:

Practicing good sleep hygiene. This involves following a regular sleep schedule, avoiding caffeine, alcohol, and nicotine before bed, limiting naps, and creating a comfortable and quiet sleep environment.
Managing pain and medical conditions. This involves consulting with a doctor about the best ways to treat pain and other health issues that can affect sleep, such as medication, physical therapy, or alternative therapies.
Using earplugs or white noise machines. These can help block out or mask unwanted noise that can disrupt sleep. White noise machines produce soothing sounds, such as rain, ocean waves, or fan noise, that can help induce relaxation and sleep.

By addressing the causes of sleep disruption and fragmentation, older adults can enhance their sleep quality and quantity, and enjoy the benefits of a good night’s rest.

How Circadian Rhythms Change and Influence Your Sleep Patterns

As people age, their circadian rhythms, which are the natural cycles of sleep and wakefulness, tend to change and weaken. This can cause older adults to feel sleepy earlier in the evening, as their bodies produce more melatonin, the hormone that regulates sleep, sooner than usual. This also means that their core body temperature, which normally drops before bedtime, decreases earlier as well.

These changes in circadian rhythms may not seem like a big deal, but they can actually affect the quality and quantity of sleep that older adults get. For example, some older adults may want to stay up later, but end up falling asleep on the couch or in front of the TV. These unplanned naps can reduce the healthy build-up of sleep pressure during the day, which helps people fall asleep faster and sleep deeper at night. Regardless of age, napping too much or too late can make it harder to fall asleep when it’s time to go to bed.

The problem can get worse in the morning, when many older adults with disrupted circadian rhythms may wake up too early, around 4 or 5 a.m., even if they didn’t get enough sleep the night before. This can create a vicious cycle of sleep deprivation and daytime fatigue, which can affect their physical and mental health.

Fortunately, there are some ways to help older adults adjust and strengthen their circadian rhythms. One way is to expose themselves to bright light at night, which can delay the rise of melatonin and the onset of sleep. This can help them stay awake longer and align their sleep patterns with their preferred schedule. However, they should avoid blue light from electronic devices, such as smartphones and laptops, as this can interfere with their sleep quality.

Another option is to consult with a doctor about taking melatonin supplements at night. Melatonin can help stimulate the natural sleep cycle and improve the depth and duration of sleep. However, melatonin is not suitable for everyone, and it may have some side effects or interactions with other medications. Therefore, older adults should always seek medical advice before taking melatonin or any other sleep aid.

Why Many Older Adults Don’t Realize They Have Poor Sleep Quality

One of the reasons why many older adults don’t realize they have poor sleep quality is that they may not notice the connection between their sleep and their health. As we age, we may experience various health issues that affect our well-being, such as chronic pain, heart disease, diabetes, depression, and cognitive decline. Some of these health issues may be caused or worsened by poor sleep, while others may interfere with our ability to sleep well. However, many older adults may not be aware of the role of sleep in their health, or they may attribute their sleep problems to normal aging. According to a survey by the National Sleep Foundation, only 32% of older adults who reported poor sleep quality said they discussed their sleep problems with their doctor.

Another reason why many older adults may not realize they have poor sleep quality is that they may have lower expectations of their sleep. As we get older, we may become more accustomed to sleeping less, waking up more often, and feeling less refreshed in the morning. We may also adjust our lifestyle to cope with our sleep problems, such as napping more during the day, going to bed earlier, or relying on caffeine or medication to stay alert. These coping strategies may make us feel like we are managing our sleep issues, but they may also mask the underlying causes and consequences of poor sleep. A study by the University of Michigan found that older adults who reported poor sleep quality were more likely to have lower life satisfaction, lower self-rated health, and higher depressive symptoms than those who reported good sleep quality.

How to Improve Your Sleep Quality and Quantity as You Age

Improving your sleep quality and quantity as you age is not only possible, but also beneficial for your health and well-being. According to a recent study by the National Institutes of Health, better sleep quality in older adults is associated with lower levels of inflammation, oxidative stress, and cardiovascular risk1. Here are some evidence-based strategies that can help you sleep better as you age:

Strategy	Description	Benefits
Keep a regular sleep schedule	Go to bed and wake up at the same time every day, even on weekends and holidays. This helps your body and mind adjust to a consistent sleep rhythm and reinforces your natural circadian clock2.	Improves sleep quality, reduces daytime sleepiness, and enhances mood and cognitive function3.
Optimize your sleep environment	Make sure your bedroom is comfortable, quiet, dark, and cool. Avoid using electronic devices, such as TVs, computers, and phones, in the bedroom or before bedtime. These devices emit blue light that can suppress melatonin production and interfere with your sleep4. You can also use curtains, blinds, or shades to block out any external light sources. If noise is a problem, you can use earplugs, a fan, or a white noise machine to mask it. You can also adjust your bedding, mattress, pillows, and pajamas to suit your preferences and comfort level.	Creates a relaxing and conducive atmosphere for sleep, reduces sleep disturbances, and increases sleep duration and efficiency.
Exercise regularly	Engage in moderate physical activity for at least 150 minutes per week, preferably in the morning or afternoon. Exercise can improve your physical and mental health, as well as your sleep quality and quantity. Exercise can also help you manage stress, anxiety, and depression, which are common causes of insomnia. However, avoid exercising too close to bedtime, as this can make you feel alert and energized, and delay your sleep onset.	Boosts your metabolism, immune system, and cardiovascular health, lowers your blood pressure and blood sugar levels, and improves your mood, memory, and concentration.
Eat a balanced diet	Consume a variety of foods that are rich in protein, fiber, vitamins, minerals, and antioxidants, such as fruits, vegetables, whole grains, nuts, seeds, legumes, lean meats, fish, eggs, and dairy products. These foods can provide you with the nutrients and energy you need to function well during the day and sleep well at night. Avoid eating large or spicy meals within three hours of bedtime, as this can cause indigestion, heartburn, or reflux, and disrupt your sleep. Also, limit your intake of caffeine, alcohol, and nicotine, especially in the evening, as these substances can stimulate your nervous system and interfere with your sleep.	Supports your digestion, immunity, and hormonal balance, prevents nutritional deficiencies and chronic diseases, and regulates your appetite and blood sugar levels.

By following these strategies, you can improve your sleep quality and quantity as you age, and enjoy the benefits of a good night’s rest. However, if you have persistent or severe sleep problems that interfere with your daily functioning, you should consult your doctor or a sleep specialist. They can help you diagnose and treat any underlying medical conditions or sleep disorders that may be affecting your sleep, such as sleep apnea, restless legs syndrome, or insomnia. They can also recommend other treatments or therapies that may suit your needs, such as cognitive behavioral therapy, medication, or devices.
