Yoga guru Baba Ramdev's claims that holding one's breath for thirty seconds to a minute can be a self diagnosing test for COVID-19 and another claim that applying mustard oil to one's nostrils can kill the virus in a person's stomach, are not supported by scientific research.

Ramdev made these claims in a 24-minute video conversation called E-agenda with Aaj Tak on April 25, 2020. A video of the interview can be seen below. At the five-minute mark, Ramdev suggests a 'self-test' for COVID-19.

He states that if a person with or without any ailments is able to hold their breath for 30 seconds or a minute without experiencing breathlessness, they are self diagnosing that they are not affected by COVID-19. He even demonstrated the same.
