Brains Flush Toxic Waste in Sleep, Study Finds
A recent study finds that the cleanup system in the brain, responsible for flushing out toxic-waste products that cells produce with daily use, goes into overdrive in mice that are asleep. The cells even shrink in size to make for easier cleaning of the spaces around them. While we sleep, our bodies may be resting, but our brains are busy taking out the trash.
The New Blue
What ECPs need to know about the latest lenses for filtering harmful blue light. The sea of HEV light in our everyday lives is swelling, but thanks to the latest advances in eyewear we are fully prepared to rescue our eyes from technology’s rising tide.
Do LEDs Cause Blindness?
According to a study led by Dr. Celia Sánchez-Ramos, of Complutense University in Madrid, light from LEDs comes from the short wave, high-energy blue and violet end of the visible light spectrum. She indicated that prolonged and continuous exposure to LED light might be sufficient to damage the retina. In a recent interview, she indicated that the problem would worsen as people live longer and children use electronic devices at a young age, particularly for schoolwork.
DOE Issues Fact Sheet on LED Lighting and the Hazards of Blue Light
The US Department of Energy has proclaimed that LED lighting is no more hazardous than other types of sources in terms of the so called blue light hazard, although all lighting products should comply with photobiological safety standards.
A few times each year, research comes to light that stakes a claim that LED-based lighting is inherently dangerous, presumably because of an excess of energy in the blue end of the human visual sensitivity spectrum. The US Department of Energy (DOE) has issued a fact sheet on the topic that refutes any such issues and concludes that white LED light is no more hazardous than light from other sources.
Go to bed tonight. On Time. (Or else.)
The sleep crisis and the science of slumber. The sleep doctors are coming and they want you to go to bed. On time. Tonight. Every night. Or else. They want doctors to add a single question to routine checks of vital signs like body temperature, pulse, blood pressure and rate of breathing. The question is: How did you sleep?
