The Genius Reason Behind This Weird Trick 🧠 Why is this coach sucking on a bag full of ice? 🧊👄 It looks absolutely ridiculous, but it is actually a genius trick from sports medicine! Many people think it helps keep the ice frozen, but that is a myth. By removing the air, they create a strong vacuum seal. This forces the ice pack to mold perfectly around an injured ankle or knee, just like a hard cast. This ensures maximum skin contact for faster recovery! 🩹 #sports #health #lifehacks #injury
