Sleep: How Much Is Too Much?

You're reading this at 2 or 3 o'clock in the morning, as your having "one of those" difficult times, aren't you?  So at this point, you probably can't imagine the possibility of getting too much sleep.  But it can happen and it also has negative health effects.

The federal government's Centers for Disease Control and Prevention just released a new study on our favorite topic, sleep, in the October issue of the journal Sleep, showing that in fact, too much sleep has health consequences.  But here's the surprise: the 

Too little sleep and you're groggy, mentally absent, struggling to take care of your physical needs of exercise and generally grumpy.  That's the easy stuff.

You're also at risk for coronary heart disease, stroke, diabetes, obesity and mental distress.  Sounds like a description of the ills of modern life, doesn't it?

To get their results, CDC researchers examined data on more than 54,000 people ages 45 and above in 14 states.  They found the vast majority (65%) were "optimal sleepers," getting 6 to 9 hours of sleep per night.  About one third (31%) were "short sleepers," getting 6 hours or less per night.  Only a small percentage (4%) were "long sleepers" who slept an average of 10 hours or more per night.  No surprises there, right?

We already know what happens to the short sleepers: stressed out, heart and blood pressure issues, "Little Mr. Cranky Pants" at the office.  But what is surprising is, they found the same chronic illnesses among the "long sleepers," except links with coronary heart disease, stroke and diabetes were even stronger.

Dr. M. Safwan Badr, president of the American Academy of Sleep Medicine (AASM), says the evidence is clear:

"Sleeping longer doesn't necessarily mean you're sleeping well."

He says people should understand that sleep affects health: a healthy, balanced lifestyle is not just about following a good diet and staying fit, but also getting the right quantity and quality of sleep.

Study co-author Dr. Janet B. Croft, a senior chronic disease epidemiologist in the Division of Population Health at the CDC, recommends doctors looking after chronically ill people begin with questions, regarding their mental health, body weight and sleep patterns and quality.

Have you noticed any of these issues in your life, as you deal with your sleeping patterns?
