The Relationship Between Sleep and Aging
As the human body ages, sleep is impacted in various ways. As a person ages, not only may the quality of the sleep alter, but the effects of sleep deprivation can become worse. Different people have different sleeping patterns, and as one ages, it can become more difficult to attain a good night’s rest. Understanding how sleep is impacted by aging can help to inform healthy sleep habits.
Various studies have found that sleep quality generally decreases with age. As a person get older, the amount of deep sleep (slow-wave sleep) they experience each night decreases significantly. Older adults also tend to have less restful sleep, with frequent awakenings throughout the night.
Additionally, age can lead to a reduced need for sleep. Although most adults require 7-9 hours of sleep a night, as a person gets older they may only need 6-7 hours of sleep. And as the quality of sleep decreases over time, older adults require more sleep to feel well-rested.
The Link Between Sleep Quality and Cognitive Health
Not getting enough quality sleep affects cognitive health in older adults, leading to physical and mental issues. Poor sleep can lead to depression, anxiety, and an increased risk of dementia and cognitive decline. Additional findings from studies have suggested that poor sleep can lead to a decrease in quality of life.
Sleep is necessary for the brain to clear out toxins, such as plaque, which can interfere with the functions of neurotransmitters associated with memory and learning. As an elderly person’s sleep quality decreases, the brain will have difficulty removing these toxins. This impairs the brain’s ability to function, leading to a decline in cognitive health.
Tips for Improving Sleep Quality
One of the most important steps in improving sleep quality is to create a consistent sleep routine. Going to bed and waking up at the same time each day helps to set your body’s internal clock and helps to improve the quality of your sleep. Limiting caffeine consumption and avoiding screens before bedtime may also help to improve the quality of sleep.
Exercising for at least 30 minutes a day can also help to improve sleep. Exercising can help to reduce stress and anxiety, improve blood circulation, and may help to relax the body. However, exercising too close to bedtime can have an adverse effect, so it’s important to finish exercising 3-4 hours before bedtime.
Creating a comfortable sleep environment can also help to improve the quality of sleep. Investing in comfortable pillows and mattresses, and blocking out noise from the environment, can make it easier to drift off into a comfortable sleep. Adding some calming and soothing elements to the environment, such as a diffuser with essential oils, can also help to improve sleep quality.
The Benefits of Good Sleep Quality

Conclusion
Sleep is an important factor for maintaining overall health and well-being, especially in older adults. Understanding the effects of aging can help to inform strategies for getting better quality sleep. By implementing a consistent sleep routine, setting the environment for good sleep, and exercising regularly, older adults can ensure they get the sleep they need to maintain health and cognitive function.
