Catching enough Z's could be more critical to your health than you may realize.

A new study out of the University of Warwick in England suggests people who skimp on sleep -- less than 6 hours per night -- could be at an increased risk for heart attacks and strokes.

When the body does not get enough rest it produces hormones and chemicals which increase the risk of serious health problems.

The findings are from a long-term study based hundreds of thousands of people from eight different countries.

It also found that lack of sleep contributes to high blood pressure, high cholesterol, diabetes... and obesity.
