Scientists at the Rensselaer Polytechnic Institute in New York have come up with another solution that’s as simple as installing some blue LEDs around the cabin. Initial testing has found that by shining blue light at certain wavelengths, a driver’s alertness can be increased and their body-clock reset.
A drawback of this method is that it’s only practical at night but researchers are investigating how the blue light affects daytime alertness of sleep-deprived and non-sleep-deprived subjects, reports New Scientist.
The researchers are already working with a number of auto parts suppliers but they claim the project is still in the early stages.
