Dr Chris Winter advises the San Francisco Giants on how to make circadian rhythms work for them on the field, reports ABC News.

“What we’re trying to do is create a situation where their brain is being tricked into thinking that whatever time the game is happening, it’s 4 o’clock in the afternoon. That’s when those athletes are at their best,” Winter said in a phone interview.

“We’re trying to help them develop smarter ways to get better sleep,” he said.
