In the past, there was usually an obvious reason for my exhaustion. After spending long hours on my feet in a hotel kitchen, lifting heavy ingredients, or getting too little sleep, feeling tired made sense. A day or two of proper rest was usually enough for my body to recover. Back then, my smartwatch was mainly a work tool. I used it to check the time, set multiple cooking timers, read urgent messages, and answer calls when my hands were busy. In a fast-moving kitchen, it was a small but useful piece of equipment that helped me stay on top of everything. I still wear a smartwatch today, but the way I use it has completely changed. It is no longer a tool that helps me move faster. Now, I use it mainly to understand how well my body has rested and recovered.
