Sleep: Gadgets giveth, gadgets taketh away

Consumer electronics can wreck sleep, but new products can knock you out, too

It's hard to imagine now, but 100 years ago people used to sleep at night. Nighttime was generally dark, quiet and boring. Must have been nice.

Then inventors, engineers and other troublemakers ruined everything by improving light bulbs and the provision of electricity. Radios didn't help, either.

Fast-forward to today. PCs and consumer electronics provide us with a gazillion things to do all night. Video games, TV, social networking, chatting with friends, catching up on work. These things are addictive, and they call to us. Getting a good night's sleep has become a challenge.

Poor sleep, or what they call " junk sleep" (sleep compromised by constant waking), particularly affects younger people -- teens and twentysomethings -- who are developing the habit of rarely sleeping well.

Sleep problems hit travelers, too. Jetlag, unfamiliar hotel rooms and other unavoidable realities of travel can make it very hard to sleep.

The recession is making sleep more challenging as well. People are lying awake nights thinking about their 401(k)s, layoffs and other stressful financial realities.

Unfortunately, a lack of sleep or even a lack of uninterrupted quality sleep, can cause serious problems. Bad sleep harms overall physical and mental performance, as well as memory. What's interesting about this is that sufferers are usually blind to the symptoms, and they think they're doing fine. Bad sleep also triggers an insulin reaction similar to eating a lot of sugar, contributing to weight gain, diabetes and obesity.

Gadgets are contributing to this problem. But gadgets can help solve it, too. Electronic sleep helpers have been around for quite a while. But a new generation of products is better than anything that's come before. In honor of the month of May, which is Better Sleep Month (who comes up with these things?), here are some of the newest and most interesting electronic sleep helpers.

  • Mobile phones are actually very nice sleep devices. If calming music helps you sleep, you should know that some phones have the ability to turn themselves off after a while, so you can use your phone to listen to music as you doze off. For example, on the iPhone, you can use the normal timer to "sleep iPhone" instead of setting it to ring an alarm.
  • Taking that a step further, there's a new iPhone app called A Good Night's Sleep. You can set a series of sounds, including peaceful music or "nature sounds" like rain or ocean waves, followed by silence. One of the settings is called "Night hypnosis," where a voice hypnotizes you into sleeping. You can set the duration and sound volume of each sound separately. A Good Night's Sleep also has a wake-up feature, where you set wake-up sounds that play in a series.
  • Sleeptracker wristwatches monitor and track your sleep patterns. You can upload the data via a USB cable to analyze the quality and quantity of your own sleep. The benefit here is that you can find out if you're getting restful sleep or if you're constantly waking in the night. The watches also come with alarm clocks built in.
  • Another newish offering is Pzizz, an application that helps you create personalized sleeping soundtracks on your Mac or PC and then import them to your mobile device so you can listen to them in bed. The makers of Pzizz claim that sleep improves the more you use their product. Pzizz helps you sleep at night and also get a quick-but-satisfying power nap during the day.
  • Most of the new high-tech sleep aids involve listening to music or other sounds, but wearing headphones and earbuds probably doesn't help you fall asleep. Regular speakers might work fine. You can also buy pillows with speakers built in, such as the Audio Pillow.
  • Makers of the Verilux TwiLight Ultra Blue Light Therapy System claim that their product uses light to convince your body to stop producing a hormone called melatonin. The idea is to regulate your body's circadian rhythms so that when it's time for you to sleep, you do so easily.

Of course, the best advice for getting sleep is to optimize your diet, get some exercise and take steps to relieve stress. But when that's not enough, these gadgets might be able to help you enjoy all the sleep benefits that people enjoyed 100 years ago.

HP OfficeJet Pro 8730

A smarter way to print for busy small business owners, combining speedy printing with scanning and copying, making it easier to produce high quality documents and images at a touch of a button.

HP OfficeJet Pro 8730

I've had a multifunction printer in the office going on 10 years now. It was a neat bit of kit back in the day -- print, copy, scan, fax -- when printing over WiFi felt a bit like magic. It’s seen better days though and an upgrade’s well overdue. This HP OfficeJet Pro 8730 looks like it ticks all the same boxes: print, copy, scan, and fax. (Really? Does anyone fax anything any more? I guess it's good to know the facility’s there, just in case.) Printing over WiFi is more-or- less standard these days.

As a freelance writer who is always on the go, I like my technology to be both efficient and effective so I can do my job well. The HP OfficeJet Pro 8730 Inkjet Printer ticks all the boxes in terms of form factor, performance and user interface.

Windows 10 for Business / Dell XPS 13

I’d happily recommend this touchscreen laptop and Windows 10 as a great way to get serious work done at a desk or on the road.

Windows 10 / HP Spectre x360

Ultimately, I think the Windows 10 environment is excellent for me as it caters for so many different uses. The inclusion of the Xbox app is also great for when you need some downtime too!

Mark Escubio

Windows 10 / Lenovo Yoga 910

For me, the Xbox Play Anywhere is a great new feature as it allows you to play your current Xbox games with higher resolutions and better graphics without forking out extra cash for another copy. Although available titles are still scarce, but I’m sure it will grow in time.
