Scientists advise ‘simple and side-effect free’ exercise for patients who have lost sense of smell due to virus
Scientists are recommending “smell training” for people who have lost the sense due to Covid, as one in five with the symptom report it has not returned to normal eight weeks after becoming ill.
The exercise involves sniffing at least four different odours twice daily for several months, which experts say is a “cheap, simple and side-effect free” way of treating the common symptom that affects some people for several weeks after contracting the virus.
