The experts all agree that a good night's sleep is one of the most important things you can do for your body. When you don't get enough sleep, nearly every system in your body suffers. Poor sleep has been linked to cardiovascular disease, obesity and diabetes. Not getting enough sleep lowers your immune system, and leaves you prone to infection. In fact, if you get six hours of sleep or less per night, you are 50% more likely to get a cold or respiratory viral infection than those people who sleep at least eight hours a night. The problem with those figures is that many of us believe that we ARE getting eight hours of sleep a night - yet we're still waking up tired, irritable and ache-y. According to well known mattress makers, Simmons Bedding Company, the right mattress can eliminate many of the reasons that people sleep poorly. Here's why. Two of the most common sleep interrupters are partner movement and discomfort. If you sleep with another person, every time they shift their position, the bed underneath you moves and your body has to adjust for that movement. When you consider that the average person shifts their position 60 to 80 times per night, it's no wonder you wake up feeling exhausted. Simmons mattresses with their patented Pocketed Coil construction are specially designed to keep your partner's nighttime restlessness from disturbing your sleep by isolating the motion, removing one of the major sleep disturbances. The other most common reason for sleep interruption is discomfort. Remember those 60 to 80 position changes per night? Most of them are triggered by discomfort, either from poor support or from excess pressure against your joints and skin. Simmons Backcare and Ortho Care mattresses are designed to reduce discomfort with a unique Zone Comfort System that provides support where your body needs it, and reduces pressure where your body doesn't need it. Replacing your mattress with one that's especially designed to support good sleep is one of the best things that you can do to improve your quality of life.
