According to CBS News, the National Sleep Foundation has released new recommendations regarding how much sleep one needs based on age. With 50 to 70 million Americans suffering from sleep deprivation, the CDC has officially labeled it as a national epidemic. Doctors say the biggest issue is seen among 14 to 17 year olds who’s biological clock keeps them up later due to increased computer use, homework and various other distractions. With an early start time for school, teenagers are not getting the foundation’s recommended 8-10 hours of sleep and are operating at a sleep deficit. The researchers concentrated on various health outcomes ranging from memory, mood and performance, to diabetes and high blood pressure.
