Sleep deprivation has become a terrifying problem in our on-the-go society, where working more and sleeping less can be seen as a badge of honor. But even nodding off momentarily can have disastrous results, as we saw in graphic news reports of the December Bronx Metro-North train derailment.
“I was in a daze,” engineer William Rockerfeller told investigators about the moments leading up to the crash. “I don’t know what I was thinking about, and the next thing I know, I was hitting the brakes.”
Sleep scientists think Rockerfeller may have slipped into what’s known as microsleep, when parts of the brain are awake and parts just doze off for a few seconds. But his momentary lack of attention before approaching a dangerous curve too fast derailed more than just the train; it also ended the lives of four people, injured more than 70 others, and probably cost Rockerfeller his career.
Short sleep, or getting less than 6 hours when 7-9 hours is recommended, drastically dampens our attentiveness and reaction times, as well as our health overall. While I’ll describe the negative effects of Short sleep, this article is really about the positive benefits of Restorative sleep, and it concludes with an excellent speech on the topic by Arianna Huffington. I hope it motivates you to add a New Years’ resolution — get more sleep. Read the rest of this entry »
As computing devices shrink in size, price and power consumption, they are being embedded in all sorts of everyday objects, including light bulbs, hearing aids, and even the human body. But what happens in 8-10 years when the pacemaker battery wears out? Today that requires another operation to replace it, but in the foreseeable future medical devices might be powered by the body itself, from heart beats, blood flow, lung contractions and arm and leg movements, as well as by electrical energy already produced by the inner ear.
That’s the message of the Wall Street Journal video below, which shows researchers investigating ways to harness the body’s energy – such as heat, sound and movement – to power medical devices.

The original Smart Home device has to be the Teasmade, and the textbooks say that a smart home is one that uses home networking technology and your internet connection to automate and simplify everyday living.
It’s the use of networking and broadband connections that takes smart home technology beyond simple home automation, where each device usually stands alone, with its own control system.
Smart home tech is a fast-growing field, from cleaning your house to opening the curtains and switching on the lights. There’s also a growing field of utility and power management, for your gas, water and electricity [and for home health care]. Surrounding them all are unified networking and control systems that can control and monitor all of your devices, not just one for each.
Past articles promoted the health & productivity benefits of good sleep, but what about a short nap? The folks at Patio Productions shared this great infographic on the science and statistics of napping, spent inside or in the majestic outdoors. Enjoy, and pass it along to friends.
As a technologist, futurist, mHealth advocate, and past Home Systems consultant, I’m a fan of embedded technologies that make products smarter and easier to use, especially those that improve healthcare, but I side with “Smart Home” skeptics and add my own comments after this press release. – Wayne Caswell, mHealthTalk editor
The Future of Smart Systems
By 2020, experts think tech-enhanced homes, appliances, and utilities will spread, but many of the analysts believe we still won’t likely be living in the long-envisioned ‘Homes of the Future’
June 29, 2012 — Hundreds of tech analysts foresee a future with “smart” devices and environments that make people’s lives more efficient.
But they also note that current evidence about the uptake of smart systems is that the costs and necessary infrastructure changes to make it all work are daunting. And they add that people find comfort in the familiar, simple, “dumb” systems to which they are accustomed.
Some 1,021 Internet experts, researchers, observers, and critics were asked about the “home of the future” in an online, opt-in survey. The result was a fairly even split between those who agreed that energy- and money-saving “smart systems” will be significantly closer to reality in people’s homes by 2020 and those who said such homes will still remain a marketing mirage.

This article features comments I posted on a James Holloway article about Smart Homes of Tomorrow, where automation is based on sensors and learned intelligence that encompasses any device providing automatic control of home functions. Systems most likely to be automated are: lights, thermostats & home appliances; television, video & music systems; security alarms & monitoring systems; and home health care monitors, alarms & communication devices.
My perspectives aren’t too far from what Mr. Holloway wrote about. They came from introducing IBM to the Smart Home market in 1994, helping it launch IBM Home Director, and retiring in 1999 to start CAZITech, a Digital Home consulting firm.
It’s True — TV Can Now Make You Healthier and May Lower Your Energy-Bills
BEAVERTON, OR–(Marketwire – Nov 15, 2011) – Leading global home networking standards group, UPnP Forum, has announced the formation of an E-Health and Sensors (EHS) Working Committee. The new body intends to address consumer-electronic (CE) industry opportunities in the areas of home personal health and wellness, as well as the increasing availability of sensor applications to monitor and control devices within the home.

The human body has many pulses, rhythms, and frequencies that can be measured and recorded. Heart rate is one of the best known, represented by beats per minute. Depending upon the efficiency of the heart, there can be wide variations in one’s heart rate. Certain conditions also impact heart rate such as exercise, stress, or anxiety.
The brain has electrical frequencies that can be measured and changes during the day are normal. Sleeping slows the brain frequency to a very slow rate allowing the body to rest. Sleep brain waves are known as delta brain waves. Read the rest of this entry »

In the modern world, sleep is the ultimate human balancing act, providing rest and recovery while living in a 24 hour stimulated environment with lights, noise, smells, toxins, and stressful events continuously. As a result, many people suffer from sleep loss and sleep related issues.
From chronic disease to athletic performance and mental acuity, if you lose sleep it impacts your life in some way. It is not just the amount of sleep but also need the right type of sleep. Slow wave sleep allows the body to restore at the cellular level. Without this cellular repair, the risk of disease increases for obesity, diabetes, depression, and hypertension. Loss of sleep also affects our day to day performance. Sleep loss impacts athletic performance, memory recall, focus acuity, and reaction time.
Thirteen years after a freak accident left her paralyzed, Rosemarie found a new mission in life: sharing what she has learned about Universal Design. She founded Universal Design Living Laboratory and is building a national demonstration home that will be opened to the public this fall. I’ll be writing a series of articles about her project and start with this, her story.
About The Demonstration Home Project
On June 13, 1998 my husband, Mark Leder, and I decided to celebrate our anniversary by going on a bicycle ride. It was a beautiful day with a clear blue sky, perfect biking weather. I was riding down the path ahead of Mark, when he heard a loud crack and yelled, “Look over there something is falling!” I glanced back at him and suddenly a 3 1/2 ton tree came crushing down on me, leaving me injured on the bike path. My life was changed in that instant! I was paralyzed from the waist down with a spinal cord injury.
