If you like to turn off that alarm clock on the weekends and sleep an extra few hours, I hate to be the bearer of bad news, it may be leading to poorer health!

FOX's Jim Mackay explains why:

We all have done it at one point or another, forgetting that early morning sunshine and grabbing a few more hours of sleep, however over time, that leads to mood swings and fatigue. In fact, every hour of deviation from your normal sleep routine could increase your risk of heart disease by 11 percent.

This is all data in a new study conducted by the Sleep and Health Research Program at the University of Arizona in Tuscon. Overall study finds regular sleep schedules are a cornerstone for good health and that the average person should get at least seven hours of sleep per night.
