Future LED Bulbs Can Help Developing Countries Lower Illness Rates
Insects tend to hang around lights. But with new LED light bulb developments, insects like mosquitoes that cause Malaria could become less attracted to them and even stay away, making it safer for humans.
Los Angeles, California - How many researchers does it take to change a light bulb? And how many lives could they save by changing it? The answer to both questions is more people than you might expect. In the developing world, light bulbs might as well be insect magnets. The light they emit – particularly the blue wavelengths of LED lights – is attractive to a range of insects, drawing them out from the night and straight to people’s homes. Many insect species are attracted to light, which means that the type of bulb you use can actually increase the risk of catching vector-borne diseases. Six million people worldwide, mostly in Latin America, are infected with Chagas disease, which is transmitted by a bug that is attracted to lights. Sand flies, also attracted to light, infect people with a protozoan parasite responsible for 20,000 deaths annually. And mosquitos, which carry malaria, are well documented as being attracted to light.
