What happened to my sense of smell?

BBC World Service - CrowdScience, What happened to my sense of smell?

What happens when our sense of smell is disrupted or disappears all together?

What happens when our smell sense changes or disappears? We hear about the science of smell and how to regain smell loss after Covid.

It took a while before it was officially recognised as a major symptom of Covid-19, but loss of smell has affected up to 60 percent of people who have had the virus. And for a significant portion, smell continues to be an issue for weeks or months after their recovery. So what’s going on and how can you get your sense of smell back? 

We tend to think of our sense of smell as something universal – if it smells bad to me, it probably does to you but that is not the case for CrowdScience listener Annabel, who wonders why things other people love to sniff, she finds disgusting. Anand Jagatia investigates the science of smell, gets up close to the world’s smelliest plant and finds out if smell training can help those with long-term issues after Covid.
