My mother sleep badly and suffer preventable spinal pain because their bed is too hard for her body type and condition. We found out that the mattress is too hard, and it causes pressure points and reduced circulation, requiring the muscles to work harder to keep the spine straight. However, if a mattress is not supportive enough, then the spine may sag out of alignment and again create tension leading to dysfunction and pain. Ideally, a mattress should be firm, comfortable and supportive, but not too hard as has been recommended by some specialists in the past. The line of the spine should be straight when lying on the side, and a natural curve maintained when sleeping on the back. My wife and I suggested that she needs to replace her old bed with a new one that she will be comfortable enough whenever she laid on her back. We are happy now that she is not complaining with all the pains she is enduring before with her old bed. When you shop for a new bed, take your time making your choice. Lay on the bed in the showroom, take your own pillow, take your shoes off, and try it out for at least 20 – 30 minutes before you make your decision. Often a bed that feels great at first becomes uncomfortable after a few minutes. You are going to spend a third of your life in bed, at least spend 20 minutes trying it out.
