The biggest impact on sleep - lately it has been listening to sound bowls from YouTube, works every time. The sleep classes I’ve taught (for menopause yoga) included pillows and bolsters for maximum comfort, and poses such as legs up the wall. Instead of “Om” at the end of the class, I included Bhramari breath (humming bee breath). I think this is a really important topic because so many people aren’t sleeping well, and sleep is a foundation of good health.
