Less-Than-Optimal Sleep May 'Age' the Brain
Date:5/1/2011

arious studies have shown sleeping too little or too much increases the risk of dying, having a heart attack or stroke and other health problems.

"Getting enough sleep helps many brain functions," Ramos said. "It is restorative, it lets you concentrate better and process new information better and faster."

It is not clear why too much sleep may be unhealthy, Ramos said. However, he speculates, it may be a sign of other health problems.

Ramos added that to stay healthy, sleep is as important as eating well and being physically active.

"We have to think of sleep the same way as we think about diet and exercise," Ramos said. "If we want to have a healthy lifestyle we think of diet and exercise, but part of the equation is that good sleep should be part of having a healthy lifestyle for healthy aging."
