Computer Time May Hurt the Heart

Computer Time May Hurt the Heart 

1.Concentrating on the screen too long causes the formation of bluish bags under the eyes.
Looking fixedly at a computer screen for extended periods causes eye fatigue and a restriction in blood circulation wich is responsible for the formation of bluish bags under the eyes.
To reduce the appearance of these bags lightly applying pressure to the bone that runs under the eye is recommended. Start from the inside corner of the eye and work your way to the outside.

2.Heart Health Goes Down the Tubes
For the study, which is due to be published in the Jan. 18 issue of the Journal of the American College of Cardiology, researchers at University College London and the University of Queensland in Australia followed more than 4,500 adults who took part in the Scottish Health Survey.
Participants were over age 34 and were followed for an average of 4.3 years.
To figure out how much leisure time was spent sitting, researchers asked: “Thinking of weekdays, how much time, on average, do you spend watching TV or another type of screen such as a computer or video game?

3.Blue light and your sleep
Exposure to light through the eyes helps regulate the body’s sleep/wake cycle by affecting the pineal gland’s secretion of melatonin. This hormone is produced at night and promotes drowsiness. Exposure to light, notably blue light, suppresses it. This is one way sunlight contributes to alertness, and why lack of light at night helps increase sleepiness.
The potential problem is that LED screens produce enough blue light that, when the devices are used close to bedtime, they can greatly reduce melatonin and increase alertness, and thus delay the onset of sleep and reduce deep sleep. And the less sunlight you get during the day, the more sensitive you become to the melatonin-suppressing effects of light at night.
Computer work or games can interfere with sleep simply because they are stimulating. So researchers have compared the effects of doing exciting or boring tasks on LED screens or on old-style screens (as well as on bright LED screens versus darker ones) before bedtime. At least a few small, short studies have found that bright LED screens have the biggest effect on melatonin production, alertness and/or sleep onset and quality, particularly when stimulating tasks are done on them.
Research on blue light and its effect on sleep (and health in general) is in its infancy. More needs to be done to determine which LED screen variables affect sleep most—for instance, the brightness and size of the screen, your distance from it, when and how long you use it, your sensitivity to blue light and so on. And, of course, the effects depend greatly on what you’re doing on the computer.

4.Hours or staring blank-faced at the screen can cause sagging of the skin.
Have you ever caught sight of your expression when working on a computer? More often than not, our faces are completely emotionless. However, lack of use of the facial muscles accelerates the rate at which the face sags and wrinkles form.
Many will be using their computer for work, so abandoning it for sake of health and beauty is out of the question. However through simple facial exercises it is possible to prevent the unwanted side-effects of living in the modern age. Forming the English vowels with the mouth stretches it and the surrounding areas enough to amply tighten the muscles. It is recommended carrying out these pronunciation exercises a total of 10 times a day.

5.How Sitting Harms the Heart
Though previous studies have found the similar associations between time spent sitting and the risks for heart attacks and strokes, scientists still aren’t sure why being sedentary appears to be so bad for the body
