Study: Extra hour of sleep won't help

November 5, 2010 (CHICAGO)

The switch takes place at 2 a.m. on Sunday. Experts said people will likely appreciate that extra hour of sleep but it won't be enough to eliminate any major sleep debt they may have accumulated due to a hectic lifestyle.

The American Academy of Sleep Medicine said chronic sleep deprivation can affect attention levels, reaction time, mood and lead to potential health problems.

The group said preschoolers should get up to 13 hours of sleep, school age children up to 11 hours, teens at least nine hours and adults seven to eight hours every night.
