Dec 28, 2015: Arguably, light is the most powerful force in nature. It is capable of influencing almost everything–from our mood to cells and metabolism. It has been established that blue wavelengths signal the brain to produce cortisol to make us alert whereas red wavelengths allow the production of melatonin to help us sleep. This cycle once followed the sun and moon. But the introduction of light bulbs and smart phones, especially light bulbs, changed that. Now efforts are being made to use light bulbs to change it back.
According to Fred Maxik, founder of bulb maker Lighting Science Group, the science has led us to understand that the light we?ve been using for the past 100 years has caused damage to us. When our circadian rhythms went wrong, it increased our risk of developing obesity, depression, and in few cases even cancer.
He further says: ?We have the ability to create lights that have purposes other than just illuminating our world.? Such bulbs have been introduced. Only last year, the Renton School District in Washington installed tunable LEDs. They can be adjusted from red wavelengths, to calm students after recess, to blue, to improve test-day concentration. In another such case, the Seattle Mariners installed LEDs at Safeco Field that can make night-time games look more like day. The New York Yankees plans to do that in 2016.
National Aeronautics and Space Administration (NASA) plans to change the bulbs on the International Space Station this year, where the sun sets every 90 minutes. The constant light makes astronauts chronic insomniacs. The new bulbs will gradually shift from blue wavelengths, during the workday, to red when the crew needs rest. LEDs like new Genesis Light by Lighting Science, which will be available in the market by January 2016, will do the same for homes.
