Surya Bhedana is a more activating and stimulating pranayama, with a stronger effect on your energy.
It is always suggested to balance the heating effect of Surya Bhedana with Sitali or Sitkari. This is a complete class that starts with Surya Bhedana and finishes with Sitali.
Contraindications: if you are pregnant or on your cycle, do not practise Surya Bhedana.
