Prostration provides health benefits by discharging positive electromagnetic charges from the body. A non-Muslim scientist's research concluded that putting one's forehead on the ground allows the body to ground these positive charges, similar to how buildings are grounded to discharge electrical signals like from lightning. Placing the forehead directly on the ground or on sand while facing Mecca allows for the most efficient discharge, as Mecca lies at the center of the Earth. Thus, prostration during prayer has scientific benefits in addition to being an act of obedience to God.
