sleep

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.
