This pranayama yoga class calms the nervous system using a series of yoga breathing exercises, including deep breathing (diaphragmatic breathing) - which combines the belly, mid-chest and upper chest breaths - and alternate nostril breathing, or Anulom Vilom. The alternate nostril breath is a challenging breathing technique, so don't be surprised if you find it difficult the first few times. This class is great to do before bed or when you need to relax.
