Do You Really Need That Much Sleep?

If you ask any random person on the street how many hours of sleep they think they should receive each night, they will almost certainly say eight.

Where did this gold standard originate, though? Is this even true? Is anything more or less bad for you? Here's what we currently know.

According to the Centers for Disease Control and Prevention, once you've beyond the teenage years, you need "7 or more" hours of sleep per night.

They change their guideline to 7 to 9 hours once you are 61 years old, and 7 to 8 hours once you reach 65. 

 A regular sleep schedule indicates that a person is paying attention to other elements of their physical health. 

According to the Centers for Disease Control and Prevention, people who receive the proper amount of sleep are less likely to get sick.
