It is generally not recommended to do Kapalabhati or any other vigorous exercise immediately after a c-section delivery. It is important to allow your body to rest and heal after delivery before starting any exercise program. Generally, it is advisable to wait for at least 6-8 weeks after delivery or until your doctor gives you clearance to start exercising. Additionally, it is important to consult your doctor or a licensed healthcare provider before starting any exercise program to ensure that it is safe for you, especially after a c-section delivery. They can advise you on when it is safe to start exercises, and which exercises are appropriate for you based on your individual medical history and condition.
