Śpij, jedz i ruszaj się zgodnie ze swoim rytmem okołodobowym

I'm curious about the personal or scientific moments that led to writing this book. Did any particular discovery or experience spark this passion?

While the science makes sense, applying it to daily life sometimes felt overwhelming. How have others integrated these habits long-term?

Since everyone's internal clock can vary, I wonder if the recommendations are flexible or need customization for different lifestyles.
