Bouncing on a piston slime block setup accumulates fall damage

Built a contraption that uses a tripwire to detect if a player is standing on a said slime block and triggers the piston underneath to shoot the player upwards. Its a jump pad. If you bounce on it a couple of times it quickly becomes very deadly. Even landing on an elevated surface takes massive amounts of damage. I presume this is because the game is accumulating fall damage when I bounce.
