.Pressure is the application of force over a particular area. In mathematical terms, pressure is equal to force divided by area. With more force comes more pressure, and with more area comes less pressure.A bed of nails has lots of points that are close together there's a lot of surface area for the body to cover. Hundreds of nails support the weight of your body instead of just one. Typically, your body doesn't exert enough pressure on any one nail for it to break the skin. The resulting force is distributed over all of the nails, so you shouldn't be injured.
