Football players participating in the sleep study at Clemson receive data on their cell phones.
CLEMSON — Hunter Renfrow whipped out his iPhone, scrolled through the applications on his screen, then found the one he was looking for. “Ah-ha,” the Clemson wide receiver said. “I’ll show you.” His right thumb gently tapped an app called “Rise” and within seconds a plethora of detailed information about his sleep habits lit up the cell phone’s screen. There were charts and statistics, patterns. Data galore. He could see how many hours of sleep he was averaging per night over the course of the week — eight hours and three minutes — and he could see exactly how many minutes his sleep was considered “restless” each night complete with tossing and turning.
