Recently, researchers have recognized that math is a discipline that should be included in collaborative approaches to sleep-related issues, reports LiveScience.

“To understand sleep, we try to reformulate biological questions in terms of mathematics, typically systems of differential equations,” she explained. “Sleep is both regular and random. It’s regular in that we go to sleep generally at the same time of day. The randomness occurs in infants who seem to have no pattern to their sleep cycles and in the variability of when we might wake up during the night. I’ve been investigating how neural structures in the brain affect the random and regular transitions between sleep and wake.”
