Why reading on a screen before bed is a bad idea
By: Damon Beres
You’ve heard that using screens before bedtime can mess with your sleep, but new research suggests the problem is even more serious.
Reading from an iPad before bed not only makes it harder to fall asleep, but also impacts how sleepy and alert you are the next day, according to new research from Brigham and Women’s Hospital in Boston, Massachusetts. The study, published in the journal Proceedings of the National Academy of Sciences on Monday, said the findings could impact anyone who uses an eReader, laptop, smartphone, or certain TVs before bed.
How Smoking Harms Your Vision
Smoking is the single largest preventable cause of disease and premature death in the United States. It harms nearly every organ in your body — including your eyes.
Adverse — and often fatal — health effects of cigarette smoking such as heart disease and cancer are all too familiar, but sight-threatening vision and eye problems generally are less well-known.
Here are more reasons you should kick the habit:
Smoking and Cataracts
Cataracts (clouding of the eye’s natural lens) are a leading cause of blindness in the world. More than 50 percent of Americans will have a cataract or have had cataract surgery by age 80.
Smokers significantly increase their risk of developing a cataract compared with non-smokers. In fact, studies show that people who smoke double their chance of forming cataracts, and the risk continues to increase the more you smoke.
Smoking and Macular Degeneration
Age-related macular degeneration (AMD) affects the center of the retina, which is responsible for sharp, central vision needed for everyday tasks such as reading and driving.
Macular degeneration causes “blind spots” and often severely impairs central vision. AMD is the leading cause of permanent vision loss among Americans age 65 and older.
Studies show smokers can have a three-fold increase in the risk of developing AMD compared with people who have never smoked. And female smokers over age 80 are 5.5 times more likely to develop AMD than non-smokers of the same age.
But it’s not all bad news: because smoking is the biggest controllable risk factor associated with AMD, quitting smoking at any age, even later in life, can significantly reduce your risk of developing AMD.

Ebola epidemic ‘out of control’ says charity (Video)
Global medical charity Doctors Without Borders has given warning that the Ebola crisis in West Africa is “unprecedented, absolutely out of control”, as states across the world took steps to prevent its spread.
Bart Janssens, the charity’s director of operations, warned there was no overarching vision of how to tackle the outbreak, in an interview with Belgium’s La Libre Belgiquenewspaper.
“This epidemic … can only get worse, because it is still spreading, above all in Liberia and Sierra Leone, in some very important hotspots,” Janssens said.
