AYUSH - the Ministry of Ayurveda, Yoga & Naturopathy, Unani, Siddha and Homoeopathy in India - has issued some recommendations to help boost immunity which plays a large part in maintaining our optimal health.
Suggestion 1: start with the daily rituals of drinking warm water, practising breath control and eating immune boosting spices.
As explained by AYUSH:
"We all know that prevention is better than cure. While there is no medicine for COVID-19 as of now, it will be good to take preventive measures which boost our immunity in these times.
Ayurveda, being the science of life, propagates the gifts of nature in maintaining healthy and happy living. Ayurveda’s extensive knowledge base on preventive care, derives from the concepts of “Dinacharya” - daily regimes and “Ritucharya” - seasonal regimes to maintain healthy life. It is a plant-based science. The simplicity of awareness about oneself and the harmony each individual can achieve by uplifting and maintaining his or her immunity is emphasized across Ayurveda’s classical scriptures.
Ministry of AYUSH recommends these self-care guidelines for preventive health measures and boosting immunity with special reference to respiratory health. These are supported by Ayurvedic literature and scientific publications.”
