A quick summary
Yoga for Better Sleep sets out sequences of yoga Asanas, breath practices and meditations to help prepare the body for sleep. It also sets these in the context of yoga teachings about sleep, along with the latest neuroscience and a thoughtful overview of the historical, cultural and medical attitudes to sleep that affect us today. The Asana sequences are suitable for beginners, but if you are new to yoga, it would be helpful to have a teacher go through them with you, and even more importantly, to check you are doing the breath practices correctly. If you have some experience, you will be able to go ahead and try out the sequences that address your particular needs.
