NASA blue light at the beginning of the day to encourage alertness

NASA is currently looking for ways to trick astronauts’ brains into maintaining a 24-hour cycle of sleeping and waking without the environmental cues of sunrise and sunset we take for granted on earth. They have invested $11.4 million to replace the lights in the International Space Station with bulbs capable of casting blue light at the beginning of the day to encourage alertness, full-spectrum white light for the day to maintain wakefulness, and red light to foster sleepiness at the end of the day.
Maybe those light bulbs will become available to the public someday. In the meantime, we’ll have to rely upon the earth’s revolution to bring us the sunrises and sunsets we need to wake and sleep well.
