Introduction

Do you know that feeling when you lie down at night but your thoughts won’t switch off? Quality sleep is the foundation of health, yet modern lifestyles often rob us of it. Sauna can be a natural solution – the heat relaxes muscles, reduces stress, and prepares the body for restful sleep.
