How it works
When you sleep on a spring mattress, the surface is shaped by the lowest or heaviest body points, which push down on the spring coils.
The higher points of contact do not press down on the springs, and because of this little or no support is being provided in these areas.
Pressure points
Because your body is pressing down on the springs at the low areas, these springs push back, creating pressure points.
A pressure point can create the same effect as when you compress an injury to stop bleeding. That is, it restricts blood flow to these areas.
Nerves are irritated
Your nerves react to this restricted blood flow. You may wake up to experience the familiar pins-and-needles sensation from a part of your body that “goes to sleep.”
Awake or asleep, when your nervous system senses this pressure and loss of blood flow, it forces your body to change position.
Tossing and turning
Because an innerspring mattress creates these pressure points, frequent shifting and moving are necessary.
The average sleeper on a conventional innerspring mattress will change position 80 times per night!
Interferes with sleep cycle
The human body is usually immobile when deeply asleep. This is the deep-sleep cycle that enables the body to rest and repair itself.
Pressure points, discomfort and tossing and turning may shorten or even prevent this cycle.
