sleep quality and quantity

when you’re feeling sluggish, the first thought is often “looks like i need to go to bed early tonight.” and while more sleep is always a good thing, a study recently published by the university of sydney challenges the assumption that the amount of hours spent asleep is the sole determiner in how rested you feel. as it turns out, poor sleep quality is linked to worse functioning, regardless of how long you sleep. why is quality sleep so important, and how can you ensure that you’re getting it? rapid eye movement (rem) sleep is the last stage and occurs in cycles of about 90-120 minutes.




scientists believe that rem sleep also aids in forming new memories, restoring and balancing brain chemistry, and stimulating the central nervous system. those that suffer from sleep apnea repeatedly wake up throughout the night to catch a breath, which means that the progression of the sleep cycle is continually interrupted. when that happens, the patient falls back into a lighter stage of sleep — so the full benefits of rem, dreaming and a quality night’s sleep are never experienced. dr. jeff rodgers is certified in dental sleep medicine and has successfully treated patients with sleep apnea for over a decade. at his practice, sleep better, georgia, dr. rodgers can evaluate your symptoms and provide highly effective, non-invasive oral appliances that will help if you are diagnosed with sleep apnea.

some people are gifted with genes that pack the benefits of slumber into an efficient time window, keeping them peppy on only four or six hours of sleep a night, according to researchers at uc san francisco. we’ve shown that the case is similar for sleep.” for over a decade, ptacek and co-senior author, ying-hui fu, phd, both members of the ucsf weill institute for neurosciences, have been studying people with familial natural short sleep (fnss), the ability to function fully on – and have a preference for – four to six hours of sleep a night. the difference, fu said, is that with fnss, the brain accomplishes its sleep tasks in a shorter time. the team chose to look at mouse models of alzheimer’s disease because that condition is so prevalent, said fu. fu and ptacek believe that similar investigations of other brain conditions would show the efficient-sleep genes conferring comparable protections.

there’s a dogma in the field that everyone needs eight hours of sleep, but our work to date confirms that the amount of sleep people need differs based on genetics. in addition, improving sleep in healthy people may sustain wellbeing and improve the quality of time we each have, the researchers said. but pursuing the many genes involved is a long game that they liken to putting together a thousand-piece jigsaw puzzle. “this work opens the door to a new understanding of how to delay and possibly prevent a lot of diseases,” said fu. “our goal really is to help everyone live healthier and longer through getting optimum sleep.” authors: additional authors on the study include qing dong, nicholas w gentry, thomas mcmahon, maya yamazaki, lorena benitez-rivera, and tammy wang, all of ucsf and li gan of weill cornell medicine.

ten hours of fragmented or poor-quality sleep won’t be as healthy as seven hours of decent, restorative sleep. one study that looked at 1.1 sleep quality is different from sleep quantity. sleep quantity measures how much sleep you get each night, while sleep quality measures how however, sleep quality and sleep quantity are not directly associated. in other words, people may sleep for a long period of time,, sleep quality pdf, sleep quality pdf, what is a good sleep quality score, how to measure sleep quality in research, sleep quality test.
