Kids are natural climbers. They climb trees, fences and just about anything they can grab hold of.

Unlike adults, children do not have self-imposed limits and they have fewer preconceived notions about what their bodies can and cant do. With its skittle-colored handholds, an indoor climbing gym is the ideal jungle gym for kids.

Beyond the non-stop fun, indoor climbing offers kids valuable and lasting physical, mental and social benefits.

Physical

What makes climbing a unique physical activity is the multitude of movements that are utilized to ascend walls at different angles with a variety of holds. Instinctually, when a child learns to climb, he or she starts to discover their body mechanics as they build strength, increase balance, flexibility and power. This low-impact activity keeps kids burning energy while they rise to the challenge of pulling, pushing, twisting and stretching their body in a healthy way.

Mental

While most people think of climbing as purely physical, it actually requires a variety of mental abilities. Climbing can easily be compared to solving a vertical puzzle. It is an exercise in problem-solving and decision-making. A child must decipher the correct sequence of movements to link a particular set of holds in order to reach the top. This problem-solving aspect makes climbing a fun lesson for learning to create solutions to lifes future challenges.

In addition, climbing offers children an opportunity to learn long-term goal setting, which contrasts todays culture of instant gratification. To complete longer climbs, children must develop traits such as concentration, discipline, and focus traits that are easily transferable to school or later in the workplace. Its no accident that top-level climbers tend to be high achievers in life.

Lastly, climbing allows kids to move outside of their comfort zone in a controlled environment. When a child conquers one climbing challenge, there is another waiting, and they can learn something new from each one. Breaking through these barriers builds a childs confidence and teaches them to overcome fears in a productive way.

Social

While climbing is considered an individual sport, there are plenty of opportunities for one to develop communication skills, trust and friendship. Its common to see kids encouraging each other. Sharing climbs and solving challenges together allow young climbers to push each other constructively and build close friendships.

Although climbing can be casual and social, filled with physical or adventurous challenges, or provide a growth opportunity when pushing through mental barriers, the reality is most people climb because it is fun.
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.
