A blinking solution to dry eyes
Blinking 20 times in a row every 20 minutes combined with looking away from the screen for 20 seconds and focusing on an object 20 feet away can prevent eye strain in computer users. The ‘20-20-20-20’ strategy has been designed as a solution to computer vision syndrome (CVS) which affects millions of workers and gamers who spend alot of time in front of screen.
CVS symptoms — dry and tired eyes, headache, sore neck and painful wrists — are usually temporary but overuse forces people to seek medical help.
Exercise boosts self control
Short bouts of moderately intense exercise boost brain function and self control by increasing blood and oxygen flow to the brain. Physical exercise is particularly important for children and teens because higher brain functioning boosts academic achievement and helps control behaviour and emotion. Exercise is already used to treat conditions characterised by impaired higher brain functions, such as attention hyperactivity deficit disorder and autism, and has been proven to help delay the ravages of dementia.
Texting becoming a pain in the neck
With the world getting more connected every minute, it’s rare to not see someone with their head down texting on their cell phone or reading status updates. Too much of it tilting your head down can become a pain in the neck for some, giving you what is being termed as a “text neck.”
Looking down puts abnormal stress on the neck muscles, causing fatigue, neck spasm and stress headaches. Since every degree of motion to the front or side that you move your head magnifies the stress on your neck. Instead, modify the position of your device — hold it at a neutral, eye level position. And, most important, take frequent breaks between playing with your phone or tablet.
Caffeine mix to stave off stroke: Study
When it comes to choosing between tea and coffee, the best answer may be to opt for both. A study by the American Heart Association’s journal, Stroke, have found that individuals who enjoy a daily cup of coffee were 20% less likely to have a stroke, compared to those who shunned the drink.
