How LED Lights Destroy Your Health

LED lights Dangerous For Your Health! Energy experts and the public were ecstatic when science introduced LED lighting to the world. LEDs (light emitting diodes) use one-tenth the electricity of regular incandescent bulbs and half the power of fluorescents. They can last for decades before burning out. And they save consumers $100 over the life of a single bulb.The new technology was quickly embraced by the Governments. LEDs are now in wide use for outdoor public and street lighting. Today, nearly 13% of outdoor lighting across America is LED.But there’s a problem. There’s increasing evidence that LED lights are dangerous for your health. The American Medical Association (AMA) recently issued a strong warning. The physicians’ group cautioned that LEDs emit blue light that causes insomnia and increases the risk of heart disease, diabetes, obesity, and cancer.

LED lights Dangerous for plants too. The AMA says it affects the growth of trees and other vegetation. The coauthor of the AMA report is Mario Motto. He is past president of the Massachusetts Medical Society. He says that the LED lights aren’t just bad for people, but they’re bad for the environment.

A far greater impact blue light has on your body than other parts of the light spectrum. It disrupts your natural circadian rhythm when you are exposed at night. It depresses your production of your body’s sleep-promoting hormone melatonin. Over time experts say that this can have a disastrous effect on your health.

Michael Siminovitch is researcher and director of the California Lighting Technology Center at the University of California at Davis. He has extensively studied LED lighting. He said that the blue light really negatively impacts people’s physiological well-being.

And it doesn’t matter if you are exposed to LEDs inside your home or outdoors. Computer screens, smartphones, indoor LED lights, e-readers, and tablets all emit blue light.

A Harvard Medical School, researchers found in a study that using a tablet and e-reader leads to poor-quality sleep and it affects on how long it takes you to fall asleep. Tablet users woke up groggy in the morning.

As pointed out by the researchers sleep deficiency and chronic suppression of melatonin are linked to a myriad of serious health problems. They include obesity, heart disease, and diabetes. Not to mention colorectal, prostate and breast cancers.

Dr. Charles Czeisler, director of the Division of Sleep Medicine at Harvard Medical School said that they showed that reading from e-reader light-emitting devices has profound biological effects.

How to Limit Your LED Risk

It’s almost impossible to avoid LEDs entirely because they are everywhere. But there are simple steps you can take to limit your risk.

  • Enforce a screen curfew. Stop using TVs, smartphones, tablets, computers or other LED devices within two hours of bedtime.
  • Secure your bedroom. Make sure there are no LED lights in your bedroom. It also makes sense to limit LED lights in other rooms you frequent just before bedtime.
  • Use an anti-blue light apps. They are available for both Android and Apple devices. These apps automatically reduce blue light from your device after the sun goes down.
  • Back off. Keep the screen minimum at 14 inches from your face.
  • Use a filter. If you must answer email or do other tasks involving a LED screen at night, use a blue light screen filter. These filters are available at electronics stores and they shield you from the blue, sleep-destroying low-end of the light spectrum.

But there’s one more thing you can do. Some cities are fighting back as the health dangers of LEDs become more evident. Encourage public officials in your community not to use high-intensity LEDs for outdoor lighting.

New York City has already begun switching street lights to a lower-intensity version of LEDs with less blue light due to public complaints.
