Why Some People May Not Need 8 Hours Of Sleep

The Centers for Disease Control and Prevention (CDC) recommends adults ages 18 to 60 get seven hours of sleep, or more, per night. But now, University of California scientists have found that the ability to fare well on short sleep is a genetic trait.

Blood samples from short sleepers revealed that they are usually more energetic, optimistic, have higher pain tolerance, and increased longevity. There’s still more research needed, but it’s thought that figuring out a person’s unique, individual internal clock could lead to much more personalized and effective health care.

Steven Lockley, with Harvard Medical School adds, “Hopefully in the next five to 10 years, you’d go to the doctor, give a breath test or a pee sample, and the doctor would know your biological time. Then all your test results and treatments could be based on your real internal time, which is going to be very different between you and me based on our internal clocks.”
