KNOXVILLE, Tenn. (AP) — About an hour before a Tennessee football player's scheduled bedtime, he gets a reminder via an app on his phone or a text message. That's when he puts on orange glasses that block out the glow of smartphones or computer screens, making it easier to fall asleep.
All the players have been given sleeping masks as well. Some have sensors above their mattresses and under their sheets to monitor heart rate, movement and respiration rate to detect their quality and quantity of sleep.
The idea is that if they sleep better each night, they'll work better the following day.
