The pressure can cause the carpal tunnel on the underside of your wrist to compress, increasing the friction on the tendons running through the tunnel and exacerbating or causing carpal tunnel syndrome. It's much much better to train your muscles and posture to keep your wrists from resting on a surface while you type.
