One Hour Short of Mars Time A new study says exposure to blue light at the right times, along with smarter caffeine use, can help humans adjust our biological clocks to the 24.6 hour Mars day rather than Earth’s day.

Help Humans Move To Mars

The simple tricks to fool Earth-evolved humans into living on Mars time.

Living vicariously through a robot on Mars seems glamorous, and in many ways it is, zapping rocks and scooping up sand and whatnot. But the schedule is brutal–Mars has a longer day than Earth, and this is legendarily painful for everyone involved in a mission on that world. Now a new study says it’s possible to adjust, however, resetting our Earthbound circadian rhythms to follow the cycle of Mars instead of our home planet.

The innate human biological clock is not a perfect 24 hours, but rather about 24 hours and 12 minutes–not too short of a Martian sol, which rings in at 24 hours and 39 minutes. But our clocks reset daily according to Earth’s light-dark cycle, which keeps us on track, said Steven Lockley, associate professor of medicine at Brigham and Women’s Hospital and Harvard Medical School. “Our body clocks have not evolved to live on a Martian day, and when we try to force them to do so, it’s very difficult for our body clocks to reset each day,” he said.
