The best recovery tool ever invented is free and you already own it. Sleep is when the adaptation you trained for actually happens. Short nights show up in your golf as slower decisions, worse tempo, and a body that feels five years older on the back nine.
Treat sleep like training: consistent schedule, dark room, and respect for the fact that a five-hour night costs you more than any gadget can give back. You can't percussion-gun your way out of being exhausted.
