Why twenty five hertz heals bones
Seventy hertz is the magical frequency where cats purr, but drop down to twenty-five hertz and something wild happens inside your body. NASA scientists noticed that astronauts in zero gravity lost bone strength because their skeleton forgot it had to fight gravity. When researchers applied a gentle vibration of twenty-five hertz to bones, cells called osteoblasts woke up and started building new mineral scaffolding. It turns out our bones love to be shaken gently. This exact mechanical whisper tricks the body into thinking you are lifting heavy weights, even when you are just sitting completely still.
