Lavender is renowned for its ability to create a relaxing atmosphere. In fact, one of the main benefits of lavender is that it can calm without sedating . More than simply generating a serene state of mind, lavender can reduce anxiety by affecting the body's fight-or-flight response.
Basically, lavender works by calming the central nervous system and promoting slow-wave sleep, so helping you sleep longer and better. So while lavender oil might seem like something that just smells nice, it can pack a pretty powerful (and well researched) punch when it comes to helping you sleep better.
