Computer vision syndrome

Don’t be fooled by its name: your laptop isn’t really all that friendly to your lap. In fact, leaving it on your lap for too long can lead to erythema ab igne, a skin condition caused by overexposure to heat. Symptoms can range from a rash that goes away after a few days to severe discoloration that may be permanent.
Carpal tunnel syndrome
A small study published in the journal Muscle & Nerve suggested that people who spend extended amounts of time on their smartphones, tablets, or game consoles (nine or more hours a day) had significantly more wrist and hand pain. This study followed up a previous, larger study in which intensive device use was categorized as five or more hours a day. More than half of the participants who used their phones or devices intensively musculoskeletal pain or discomfort. Only 12 percent of the other group (on their devices five or less hours a day) had these symptoms. These numbers may exaggerate how long people actually spend on there phones, but study author Pete White says “caution may be warranted when using hand-held electronic devices, in order to minimize the chance of developing carpal tunnel syndrome.”
Social media is flooded with pictures of perfectly styled, drool-worthy food. They’re fun to look at, but they could also be altering your appetite. One study showed that people are more drawn to photos of foods with a high fat content than low-fat food, and they are more likely to find similar foods near them after seeing those pictures. Not only is so-called “food porn” inadvertently encouraging people to eat unhealthy foods, but it’s also making it harder for people to break that habit. Another study found that obese people have higher brain activity when they see photos of food than those of a healthy weight, especially when the foods were high in fat. The pictures even triggered a food-related brain response in obese participants when they weren’t hungry.
From answering emails on a computer at work or watching TV at home, people spend most of their time using technology in a seated position. And the more prominent technology becomes in our lives, the more time we spend sitting and not being active. According to MedlinePlus, sedentary lifestyles come with serious health risks, including a higher risk of heart disease, high cholesterol, stroke, type 2 diabetes, and certain cancers. Look out for these scary health risks of binge-watching.
The time you spend on your phone can impact how long it takes you to fall asleep and the quality of your sleep. In a 2016 study, researchers tracked 653 participants and determined the median time spent looking at their screens was 38.4 hours over 30 days. Forty-two percent of participants who spent that much or more time on their phones had difficulty sleeping, and around 35 percent of participants who used their phones for less than that also had sleep troubles. The results also showed people who used their phones right before bed were more likely to have poor sleep quality.
Looking down at your phone all day puts strain on your neck, which holds up your 10-15 pound head. The longer you stay in that position, the more work your muscles have to do, and that can result in neck pain or potentially pulled muscles. Check out more common habits that are making you sick.
You may like to turn up the volume on your headphones so that you can only hear your music, but that’s actually a dangerous habit. Aaron Moberly, MD, assistant professor in the department of otolaryngology at The Ohio State Wexner Medical Center in Columbus, told Everyday Health that headphones deliver sound very close to your eardrums. Prolonged exposure could damage your ears and even cause hearing loss. He recommends keeping the volume at or below the halfway point.
In studies by the National Toxicology Program, researchers exposed rats and other mice to radiofrequency radiation (RFR), which is emitted by cell phones, over the course of nine hours every day for two years (about 70 years for a human). The resulting exposure levels ranged from the maximum exposure that is legally allowed for cell phones to four times that amount. Researchers also found heart tumors called schwannoma in male rats exposed to “beyond the allowable cell phone emissions.” While those specific tumors rarely turn cancerous and RFR can’t cause cancer by damaging DNA, there are still concerns that this radiation could alter human tissue in ways that could cause cancer. But technology isn’t the only surprising health hazard in your life. Here are more everyday things that pose huge health risks.
