Here are seven ways technology and the high-tech lifestyle may be hurting you.
1. Computer Vision Syndrome
The human eye is not adapted for staring at a single point in space for hours on end. If you log significant time in front of a computer monitor, you’ve probably experienced computer vision syndrome: eyestrain, tired eyes, irritation, redness, blurred vision, and double vision. Luckily, this isn’t a permanent condition;
Protect your eye health by taking the following steps:
- Make sure your glasses or contact lens prescription is up to date and adequate for computer use.
- Occupational glasses may be needed for some people with the syndrome. A single or bifocal lens, or tinted lens material, may help increase contrast perception and filter out glare and reflective light to reduce symptoms of eye strain.
2. Insomnia
Working into the evening face-to-face with an illuminated monitor can play havoc with your internal clock. Replace work with exciting stuff like video games after dark, and you have an even more potent recipe for a sleepless night. One study showed that playing a game involving shooting suppressed levels of melatonin, the hormone that’s involved in regulating cycles of sleep and waking.
Chilling in front of the TV is no better. Another study showed that adolescents who watched three or more hours of television per day were at a significantly elevated risk for frequent sleep problems by early adulthood.
3. Repetitive Stress Injuries
The constant tiny movements needed to maneuver a mouse or type on a keyboard can irritate tendons; swelling can press on nerves. As little as a half hour a day of computer mouse use could put you at risk for pain in your shoulder, forearm, or hand.
“If you have enough of these circulating in your bloodstream, they can be toxic to nerve cells and other cells,” Barbe tells WebMD.
