The one surprising reason teens may be choosing to delay sex

The Internet may be to blame for selfies and misinformation, but it might also be a reason teens are becoming more responsible when it comes to their health.

A new study from the U.S. Center for Disease Control shows that teens are having sex later and less frequently.

In 1988, 60 percent of boys and 51 percent of girls 14 and older reported they had already had sex, Danielle Paquette and Weiyi (Dawn) Cai reported for The Washington Post. Those numbers have dropped significantly to 47 percent for boys and 44 percent for girls.

One possible reason for this decline could be connected to the availability of the Internet, Paquette and Cai reported.

Dr. Brooke Bokor, an adolescent medicine specialist at the Children's National Health System, said teens are turning to the Internet for advice about health and wellness, which could promote healthier views on sex.

Theyre looking on the Web, Bokor said. Theyre looking for guidance from parents, guardians and physicians. They can and will make positive decisions for their own health, both sexual and otherwise. We really need to be prepared to treat our youth and young adults as educated consumers.

A Pew Research Center study showed that 95 percent of teens are online daily, and 73 percent of them have access to the Internet through their own smartphones.

This ever increasing access to massive stores of information is giving way to more reliance on the information found there.

CNN reported that 25 percent of teens are getting their health advice by searching Google or other similar sites. The Internet is the fourth most common way of finding health information among teens, following parents, school health classes and medical providers.

While teens still do trust their parents for health information, this study certainly emphasizes the need for online accuracy.

"This study underscores the importance of making sure there is accurate, appropriate and easily accessible health information available to teens online," the study reported. "The information is used and acted upon, so it had better be good."

This is where websites like Bedsider.org, which is run by the National Campaign to Prevent Teen and Unplanned Pregnancy, come into play, Paquette and Cai wrote. The site provides teens true information about practicing safe sex and, perhaps more importantly, how to talk to parents about sex.

I mainly find it kind of moving, because it really illustrates that a lot of teens are grappling with very real, very important health challenges and that the Internet is empowering them with the information they need to take better care of themselves, Vicky Rideout, who co-authored a study on where teens found health information, told The Washington Post.
Its toxic: New study says blue light from tech devices can speed up blindness

It turns out checking Twitter or Facebook before bed is bad for your health.

A new study from the University of Toledo found that blue light from digital devices can transform molecules in your eyes retina into cell killers.

That process can lead to age-related macular degeneration, which is a leading cause of blindness in the United States, according to the researchs extract.

Blue light is a common issue for many modern Americans. Blue light is emitted from screens, most notably at night, causing sleep loss, eye strain and a number of other issues.

Dr. Ajith Karunarathne, assistant professor in the UT Department of Chemistry and Biochemistry, said our constant exposure to blue light cant be blocked by the lens or cornea.

"It's no secret that blue light harms our vision by damaging the eye's retina. Our experiments explain how this happens, and we hope this leads to therapies that slow macular degeneration, such as a new kind of eye drop, he said.

Macular degeneration is an incurable eye disease that often affects those in their 50s or 60s. It occurs after the death of photoreceptor cells in the retina. Those cells need retinal to sense light and help signal the brain.

The research team found blue light exposure created poisonous chemical molecules that killed photoreceptor cells

"It's toxic. If you shine blue light on retinal, the retinal kills photoreceptor cells as the signaling molecule on the membrane dissolves," said Kasun Ratnayake, a Ph.D. student researcher working in Karunarathne's cellular photo chemistry group. "Photoreceptor cells do not regenerate in the eye. When they're dead, they're dead for good."

However, the researchers found a molecule called alpha-tocopherol, which comes from Vitamin E, can help prevent cell death, according to Futurism.

The researchers plan to review how light from TVs, cellphones and tablet screens affect the eyes as well.

"If you look at the amount of light coming out of your cellphone, it's not great but it seems tolerable," said Dr. John Payton, visiting assistant professor in the UT Department of Chemistry and Biochemistry. "Some cellphone companies are adding blue-light filters to the screens, and I think that is a good idea."

Indeed, Apple released a Night Shift mode two years ago to help quell blue lights strain on the eyes, according to The Verge. The screen will dim into a warmer, orange light that will cause less stress on the eyes.
