Sleep is an important part of our lives, but the amount of sleep we need changes as we age. Sleep is variable from person to person, but the number of hours of sleep that are good for your health can also change during your lifetime. Research has shown that a lack of quality sleep is connected to poor cognitive function, cognitive decline and dementia in old age.

What You'll Learn
Sleep needs vary from individual to individual
The number of hours of sleep that are good for your health can also change during your lifetime. For example, a growing body of research has connected a lack of quality sleep with poor cognitive function, cognitive decline and dementia in old age. During sleep, and particularly slow-wave sleep, the body’s metabolic activities slow, allowing it to engage in restorative processes. Research in mice has found that slow-wave sleep leads to an increased flow of cerebrospinal fluid throughout the brain, allowing it to cleanse itself of debris while we rest. This may be especially important for the clearance of waste products associated with dementia.
Sleep is variable from person to person. The way that people sleep and how much they need can vary widely. For example, some people may need 8 hours of sleep each night to feel rested, while others may feel refreshed after only 6 hours. Additionally, some people may be able to function well with less sleep during the week, but need to catch up on sleep during the weekends.
It's important to prioritize sleep and not compromise your sleep habits just because you're getting older. Better sleep habits can help you get a good night's sleep. Habits that can improve your sleep include going to bed and getting up at the same time every day. Talk to your healthcare provider if you have problems sleeping.

Sleep is connected to cognitive function
Research has connected a lack of quality sleep with poor cognitive function, cognitive decline and dementia in old age. During sleep, and particularly slow-wave sleep, the body's metabolic activities slow down, allowing it to engage in restorative processes. Research in mice has found that slow-wave sleep leads to an increased flow of cerebrospinal fluid throughout the brain, allowing it to cleanse itself of debris while we rest. This may be especially important for the clearance of waste products associated with dementia. For example, disrupted sleep leads to increased levels of amyloid-β, a protein strongly linked to Alzheimer's disease.
Better sleep habits can help you get a good night's sleep. Habits that can improve your sleep include going to bed and getting up at the same time every day. This can help improve your attention and memory, allowing you to better perform daily activities.
It is important to prioritise sleep, even during busy work weeks. While you may be tempted to steal a few extra hours of work or leisure, remember that sleep is essential for your cognitive function and overall health.

Sleep habits can improve sleep quality
The amount of sleep we need changes throughout our lives, and it's important to maintain good sleep habits to ensure we get the best quality sleep. Sleep needs vary from individual to individual, but the number of hours of sleep that are good for your health can change during your lifetime.
The amount of sleep you need is the number of hours necessary to wake up without an alarm, feeling refreshed and alert. However, many adults find themselves getting only a few hours of sleep each night during busy work weeks. This can be detrimental to health, as a growing body of research has connected a lack of quality sleep with poor cognitive function, cognitive decline, and dementia in old age.
To improve sleep quality, it's important to establish a sleep schedule and stick to it. Going to bed and getting up at the same time every day can help regulate your body's sleep-wake cycle and improve the quality of your sleep. This habit can also help you get sick less often, maintain a healthy weight, and improve your heart health and metabolism.
In addition to establishing a sleep schedule, there are other habits that can improve sleep quality. These include creating a relaxing bedtime routine, avoiding stimulating activities before bed, and limiting exposure to blue light from electronic devices. Engaging in relaxing activities such as reading or listening to soothing music can help prepare your mind and body for sleep.
By prioritising sleep and developing healthy sleep habits, you can improve your sleep quality and overall health.
