What to others may seem only like a nap is enough for these people to recharge their batteries and go about their day completely rested up, ScienceNow informs. “We've believed for a long time that there's a genetic basis [to this behavior],” explains Washington University in St. Louis (WUSL) neurobiologist Paul Shaw. Investigations have revealed that a genetic mutation is actually the trigger for this ability that early risers have. And it's only recently that experts began unraveling the exact mechanisms that allow some to only rest up for a few hours at night. The basis for this line of research was set up by geneticist Ying-Hui Fu and his team back in 2001, when the expert proved that a mutation in a gene called Per2 was responsible for familial advanced sleep-phase syndrome (FASPS). In this c!
ondition, people sleep the normal average of 8 hours, except that they go to bed very early in the evening, around 6 or 7 pm, and wake up the following morning at 3 or 4 am. “After that was published, a lot of these people [with unusual sleep schedules] came to us. So we started to collect DNA samples,&r...
