Fatigue Science helps players by having them wear bands on their arms, called Readibands, which monitor sleep cycles, reports CBCNews.

The data the bands produce is then used a bit differently than other fitness bands available to average consumers.

“We have a proprietary model developed by the U.S. military, which actually takes your sleep data and transforms it into performance data,” said Woll.

“We’re actually able to tell you at the end of the day, based on how well you’re sleeping, what does that mean for your performance today in terms of your cognitive function and your reaction times.”
