Technology Could be Causing Your Insomnia

Are you having a hard time falling asleep? For most people, an adequate amount of sleep is about 7 hours a night. Inadequate sleep puts you at a greater risk for a number of diseases and health problems, including a lack of concentration and impaired judgement, accelerated aging, cardiac problems including heart disease, heart failure, high blood pressure and stroke, as well as increased risk for diabetes, depression, and weight gain.

An often overlooked cause of insomnia and other sleep-realted problems is exposure to blue light from the display of your iPad, computer, laptop, or cell phone before going to bed. When blue light hits your retina, a signal is sent to your hypothalamus and melatonin production (a chemical in your brain that causes you to fall asleep) is turned off for several hours, disrupting your natural circadian (sleep/wake) rhythm.

Using f.lux , a free utility that adjusts the glow of your technology screens will reduce your exposure to blue light. f.lux doesn’t just control brightness like newer laptops do, it controls color temperature based on the time of day, dimming your monitors later into the evening and tinting the screen color based on the kind of lighting you use, which can help you sleep better.

If you’re having difficulty falling asleep after spending time on your computer, cell phone or other blue-light emitting device, I encourage you to try using f.lux, as high-quality sleep is critical to your health and quality of life.

    This article is right on. I kind of think of it as blue being like the daytime sky and so your brain thinks it’s daytime and time for you to get moving. One of the most difficult light sources to get rid of are clocks and nightlights. We tend to get used to things and can’t imagine life without them.
