Optimal sleep linked to lower risks for dementia and early death
Short and long daily sleep duration were risk factors for dementia and premature death in a study of Japanese adults aged 60 years and older. The findings are published in the Journal of the American Geriatrics Society. Among 1,517 adults who were followed for 10 years, 294 developed dementia and 282 died. Age- and sex-adjusted incidence rates of dementia and all-cause mortality were greater in those with daily sleep duration of less than 5.0 hours and 10.0 hours or more, compared with those with daily sleep duration of 5.0 to 6.9 hours.

Effects of sleep deprivation based on individual genetics
The way that a person is affected by sleep loss is based on gene expression, according to a new study. Researchers at the Perelman School of Medicine at the University of Pennsylvania studied the cognitive effects of sleep-deprived people and found differences were reflected in microRNAs. Their findings were presented at the 32nd Annual Meeting of the Associated Professional Sleep Societies LLC in Baltimore.

Body clock disruption increases risk of depression, study finds
Disruption to the body clock increases the risk of mood disorders and depression, a large study has confirmed. Scientists at the University of Glasgow looked at the circadian rhythms - which control functions including sleep patterns, body temperature, our immune systems and the release of hormones - of more than 90,000 people to measure daily rest-activity rhythms, called relative amplitude.

Many people complain they do not get enough sleep, and it seems they are right to be concerned. Researchers have found that adults under the age of 65 who get five or fewer hours of sleep for seven days a week have a higher risk of death than those who consistently get six or seven hours’ shut-eye.

You are probably not getting enough sleep, and it is killing you
Rocker Warren Zevon is often credited with coining the mantra that’s been embraced by everyone from partying college kids to early-morning exercise evangelists: “You can sleep when you’re dead.” Or as Bon Jovi put it, “Gonna live while I'm alive, I'll sleep when I'm dead.” It’s an intoxicating thought, but the truth is that not getting enough sleep is literally killing us. That’s what neuroscientist Matthew Walker, who directs the sleep and neuroimaging lab at UC Berkeley, says in his book, ‘Why We Sleep,’ which was published in October 2017.

Is Your Teen Vamping Instead of Sleeping?
The argument for setting strict rules on cell phone usage after a teen’s bedtime just got stronger. It is becoming increasingly clear that late-night phone use, often called vamping, not only interferes with young people’s sleep patterns, it also threatens their mental health. The latest study in a growing body of research on vamping should send a big warning signal to parents of middle and high schools students. Conducted at Murdoch University in Perth, Australia, this was the first long-term study that examined how night phone use and mental health were connected.

How Being Sleep Deprived Alters a Brain Connection That Causes Fear and Anxiety
Your co-worker sluggishly walks into the office and tells you they were up all night working on their client pitch. Do you marvel at their dedication and commitment, or do you shrug it off and think, "Yeah, I've had plenty of those nights"? Odds are, your response would be the latter. After all, sleep is for the weak. It is not uncommon for us to push our bodies to an unhealthy point in hopes of reaching our goals, whether it's being a good parent and taking care of your newborn, or pulling an all-nighter to cram for the bar exam. Being sleep deprived has become such a norm in today's society that we often...
