In the Internet age, health information is only a click (or Google search) away. This ease of access to research studies, medical websites and health articles has both negative and positive consequences, bringing answers as well as anxiety.

Searching for possible causes of physical symptoms can be disastrous, causing fear and convincing people they have a rare illness, as Silje Lier, a communication adviser for the U.S. Department of Health and Human Services noted in a recent blog post.

WebMD, for example, is mocked often for the frequency at which cancer appears in its symptom tracker tool. One cartoon shows the website embodied as a doctor telling people with a broken arm, a paper cut and a sword wound that they all could be suffering from the disease.

And yet, likely because its convenient, people continue to turn to the Internet when they're looking for medical answers. Pew Research Center has found that 72 percent of Internet users have looked for health information online, and that 35 percent of U.S. adults have gone online "specifically to try to figure out what medical condition they or someone else might have."

Additionally, a recent survey from the Public Religion Research Institute found that 43 percent of millennials look online for information about sexual health, making the resource only 2 percent less popular than medical professionals, Deseret News National reported.

HHS, like many health care organizations and professionals, wants to turn the Internet into a force for good for the medical community. Its new video, called "Do you suffer from WIMS (web-induced medical stress)?," illustrates how even the simple act of reading about sitting for too many hours a day can quickly escalate into hysteria, and offers the HHS-run website www.healthfinder.gov as an antidote to ongoing confusion.

"Health information doesn't have to be confusing or scary," the video explains.

Healthfinder.gov collects health news, advice from doctors, tips on being healthy and recommendations for preventative care like flu shots all in one place. But it's not the only place people can turn to for valuable health information, Lier wrote.

He said a trustworthy website should have four key characteristics: the organization sponsoring the resource should be clearly identified, the date of publication should be noted, privacy protections should be in place and there should be a number to call for more information.

"If a health website doesn't tell you these things, go somewhere else that does get you the health information you need," Lier said.
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.
