You're not sleeping enough

Thirty-five percent reported getting fewer than seven hours of sleep on an average night, 48 percent reported snoring, 38 percent reported unintentionally falling asleep during the day sometime in the previous month, and nearly 5 percent said they’d nodded off while driving in the previous month.

The number of U.S. adults reporting that they get fewer than seven hours of sleep rose from 1985 to 2004, and that increase could be attributed to trends such as the increased use of technology and more people working night shifts, the CDC said.
