Daylight saving time has ended, with clocks falling back an hour Sunday, giving Americans the feeling of an extra hour in the morning, which could negatively affect their health.

According to USA Today, Mayo Clinic's co-director of the Center for Sleep Medicine, has reviewed about 100 medical papers related to how the time change could affect health.

The most notable changes are in those who regularly do not get enough sleep.  The sleep deprived might struggle with memory, learning, social interactions and overall cognitive performance.  Please click on the above link for more information.
