When it comes to people’s sleep goals, many of us tend to focus on how many hours of sleep they get. We hear that comment from our patients all the time here at Premier Sleep Associates. While the number of hours you are in bed to sleep is a great benchmark to start with, you also need to focus on the quality of sleep and restfulness you have to get the most out of your sleep.
Some patients report they sleep 9-10 hours per night and still don’t feel refreshed. If you have a sleep condition, such as sleep apnea, your sleep may be interrupted many times per hour without knowing it. For some, even hundreds of times per hour. This result in feeling groggy or unrefreshed the next day.
It can become harder to react quickly or grasp new concepts when you are constantly deprived of sleep. Restorative sleep needs to be both continuous and long enough to benefit the person. Sleep disorders like sleep apnea and sleep fragmentation might make it harder to get the quality of sleep doctors and researchers recommend.
In otherwise healthy adults, sleep disruption can cause many short-term consequences such as:
For adolescents, it can affect:
Sleep disruption can cause impaired cognitive functioning and behavioral problems in children.
That’s why it is essential if you or your child has sleep disruptions caused by sleep apnea to seek treatment such as oral applicance therapy or sleep-disordered breathing treatment for children.
So, which is better quality or quantity of sleep? While it’s often a good thing to get more hours of sleep, especially when you’re sleep deprived, the University of Sydney published a study challenging the thought the sleep hours are the sole determiner in how refreshed and rested you feel.
Sleep studies have long focused on the duration or quantity of sleep, enforcing the importance of getting the minimum amount of sleep required for the mind and body to function optimally.
Most adults need seven to nine hours of sleep daily, according to the National Sleep Foundation. This sleep quantity is positively linked with longevity and health status. Also, the quantity of sleep is a vital component to overall health and could impact energy and mood levels.
Sleep quality, unlike sleep quantity, refers to how well you sleep. Quality is better than quantity when it comes to sleep. You’re better off getting six hours of high-quality sleep than a longer period of low-quality sleep, reports Psychology Today.
This could explain why some individuals are just fine with fewer sleep hours than average. If you can get plenty of restorative sleep in a shorter time period, you’re well off. Few people, however, are able to do this. Most people require seven to nine hours of uninterrupted sleep.
Good quality sleep, for adults, means you generally fall asleep within a half hour or less, sleep through the night soundly with no more than one awakening and fall back to sleep within 20 minutes of waking up, reports the National Sleep Foundation.
On the other side of things, poor sleep quality is the type that leaves you lying in bed awake staring at the ceiling. It could be characterized by:
The amount of time you spend in bed is important since it indicates you have completed several sleep cycles. The natural progression of sleep from stage 1 to stage 2 then 3, then 2 and then REM is important, but the study suggests it’s the quality of sleep that ultimately restores the brain. Poor sleep quality, as it turns out, is associated with worse functioning, no matter how many hours of sleep you get.
With sleep apnea, think of it like this: someone is repeatedly tapping you on the shoulder all night long once every minute or two saying wake up and breathe! It’s amazing how unaware of how disruptive your sleep is if you suffer from sleep apnea. If this is the case with you, you may not even comprehend how you can feel so tired during the day because you just spent nine hours in bed the night before.
Many people with sleep apnea have a severely fragmented REM cycle due to the increased frequency of the obstructive events because of natural paralysis that occurs during this stage which makes the airway more prone to collapse combined with the autonomic breathing that occurs during this stage of sleep whereas the response to the increased levels of CO2 and decreased levels of oxygen makes the arousal response inhibited.
A report published in Sleep Health shows the key determinants of quality sleep. They are:
Around 35 to 40 percent of adults in the U.S. have trouble falling asleep or experience daytime sleepiness, according to The National Sleep Foundation. Improved sleep quality can help individuals feel better during the day and improve alertness. Quality sleep also plays an essential role in:
Here are some tips that can improve your quality of sleep.
The seven to nine duration of sleep a night for the average adult is essential, but if it’s being disrupting all night, no amount of time in bed or sleep time will lead to refreshing sleep. Obtaining enough good quality sleep also helps maintain a healthy lifestyle. Whether it’s getting a new mattress, setting an alarm or treating your sleep apnea, there are simple steps you can take to get your seven to nine hours of quality sleep.
