I recently wrote a column about wearable computing, in which I discussed a future in which people will eventually wear glasses and contact lenses with built-in screens, delivering content we can use. It will be like having smartphones in our eyes, but much smarter ones.
Researchers I spoke with for my column noted that it would be at least 10 years before Facebook updates were being flashed into our retinas in real time. In the interim, though, the first iteration of wearable computers are here, focusing on tracking people’s health.
“I think we are at the very beginning of wearable computing,” said Julia Hu, founder and chief executive of Lark, a start-up based in Mountain View, Calif., that makes a wearable sleep tracking monitor. “You’re starting to see a lot of sensors that track data and then visualize it.”
She added, “A big part of the first wave of wearables will be personalizing health and more importantly, making the information relevant for people.”
Ms. Hu’s company chose to focus on sleep better because, she said, more than 70 million Americans have a sleeping disorder.
Although people might think the biggest hurdle with wearable computers is the creation of the devices, Ms. Hu said knowing what to do with the data these computers capture was more important. For example, the Lark tracks more than 3,000 micro data points each night through a wrist device users put on before going to sleep. Lark’s software, which runs on a smartphone, then parses through all the micro-motions it has tracked throughout the night and makes recommendations to users.
“We use a type of sleep research called actigraphy — it’s what sleep scientists have used for the last 15 years — and then we sift through your personalized data and offer a better sleep, diet and exercise schedule,” Ms. Hu said.
Michael Liebhold, a senior researcher specializing in wearable computing at the Institute for the Future in Palo Alto, Calif., said in a phone interview that health applications made the most sense for today’s consumer-oriented wearables. Rather than offering health care, he said that new wearable devices were aimed at helping to promote wellness by helping people understand health issues before they became problems.
“We are seeing these wearables that create a health-aware environment, with sensors and devices used to monitor our health and fitness and then giving us visualized feedback of the results,” Mr. Liebhold said. He said this trend would become more pervasive as people learned to tack more sensors onto their bodies.
But one wonders if people will actually wear these devices. Although health promoting and sleep monitoring devices may be useful and responsible, they aren’t exactly sexy products for mainstream consumers. And they won’t allow us to send Twitter messages from our eyeballs.
Still, it’s nice to know they might help us get a good night’s sleep.
Have you been suffering from mysterious headaches? Are you tired, in the middle of the day—for no reason at all? Are your loved ones complaining that you’re especially irritable or moody?
Amazingly, the root of all these problems may just be your snoring. And unfortunately, snoring may be the sign of a whole range of other, more serious health problems.
Snoring—besides being bothersome to your bedmate—is a common symptom of obstructive sleep apnea. This condition, also known as OSA, actually causes you to stop breathing while you sleep; and often hundreds, if not thousands of times per night.
This halt in breathing occurs when your tongue, throat and jaw muscles relax, which then cause your airway to be blocked. When breathing stops, the body reacts with a momentary spike in blood pressure. Because these jagged halts in breathing can occur hundreds of times nightly, the effects are multiplied—and truly dangerous.
As a result, OSA has been proven to cause a range of serious health problems, including:
• Heart attacks
• Heart disease and plaque buildup
NEW YORK (Reuters Health) – A survey from the United States and Canada found 40 percent of police officers had symptoms of a sleep disorder, including sleep apnea and insomnia.
Officers who screened positive for those disorders were also more likely to be burnt out, depressed or have an anxiety disorder. And over the next two years, they committed more administrative errors and safety violations and were more prone to falling asleep at the wheel than sound sleepers.
“In general we have this cultural attitude of, sleep is for the weak,” said Dr. Michael Grandner, from the Center for Sleep and Circadian Neurobiology at the University of Pennsylvania in Philadelphia.
“When you’re in an environment where signs of weakness are particularly discouraged, there may be a social pressure to not address sleep problems or to shrug them off,” added Grandner, the author of a commentary published with the new study in the Journal of the American Medical Association.
But when police officers in particular suffer from sleep problems, he said, it becomes a public health and safety problem.
“It’s not just the people with sleep disorders that are affected,” Grandner told Reuters Health. “If they’re impaired, you’re at risk.”
Researchers say police departments could do more to make sure that officers with sleep disorders get the appropriate treatment, which may include sleep machines, therapy or changes in work schedules.
