Pranayama can be extremely beneficial for your physical, mental, and spiritual health.
However, if practiced incorrectly it can also have a negative impact.
Your breath is a powerful instrument and must be respected. Take your time and do not rush. Always stay within your limits.
If at any time you should feel unwell or light-headed then stop.
Also, if you have had any recent surgery – especially to the abdominal or chest area – if you have heart, or blood pressure issues, or have any other serious health concerns or issues then you should not practice pranayama without first consulting a medical professional.
