sleep

How much sleep is enough? Can there be both too little and too much? A new study thinks they have identified that Goldilocks range which is just right.
Substitute the word "Halloween" for any celebratory event and pervasive worry-lists abound. Fun also matters.
It's normal for a baby to be difficult to get to sleep, which is clearly exhausting for new parents. Bu, expensive "sleep consultants" aren't the answer.
What better time to learn more about shuteye than "sleep awareness week"? A new study found that not only are humans sleeping less than other primates, but we're also not getting the sleep that we should be getting. Ugh. Sleep awareness week is exhausting! It might be best to take a nap before reading this one. 
Who gets more sleep, men or women? Across the country what's the average bedtime? And how consistently do people stick to their bedtimes? Fitbit knows those answers. That's because millions of people wear their devices to bed – and the company is now sharing some of the data.
Sleep deprivation has been associated with an increased risk of obesity in several studies. A new one, based on a large British survey, assessed whether that link could be due to over-eating by bleary-eyed people. But the data didn't support that hypothesis, so researchers will have to look harder to explain that link.
Too much, too little, and just the right amount of sleep have been linked to death. Sorry. 
Check it out: the latest sleep device from Apple — the Sleep Pill for Sense, sits on your nightstand, helps you fall asleep, and helps you wake up at consistent times each day. The device has a mini-device that clips onto your pillow and it tracks your REM sleep, sleeplessness, and overall sleep health.
Tossing and turning in bed all night long, it can feel as if you're the only person in the world unable to sleep. It may be a small comfort to learn, however, that you aren't the only one. Millions of other Americans also struggle to sleep. In the latest Morbidity and Mortality Weekly Report, the CDC reports data on the prevalence of sleep trouble by age group and sex. (See chart below.) As shown, about 20% of young adults (aged 20-39) have trouble sleeping. The problem appears to get worse with age. Roughly one-third of people aged 40 and over report difficulty sleeping. In general, women have more trouble than men.
New sleeping recommendations have been released, and just in time to confirm what millions of Americans already knew: We are so sleep deprived. Yawn.
A new study published in Science shows evidence that, in mice, substances like amyloid-beta known to be increased in Alzheimer s disease and others, are removed from the cerebrospinal fluid bathing the brain at an accelerated rate during sleep.
