We all known that sleeping drivers is a leading cause of automobile deaths and accidents, but researchers are learning of less technological ways to combat dozing drivers: blue lights. The latest studies show that sleepy drivers should take a 30-minute blue light "bath" to combat drowsiness while driving. Why would one choose blue lights instead of coffee, energy drinks and cigarettes?

It's because the lights are capable of resetting and modifying a body's internal clock. Exposing the body to the short wavelengths of blue light has the strongest affect on the internal clock and is the most effective way to provide daytime alertness. The research team at Rensselaen Polytechnic Institute in Troy are also investigating putting LED lights in the cabs of trucks and vehicles to provide the light "baths" while driving. [New Scientist]
