With Winter approaching, it feels like a good time to discuss what we can do to make our bodies better at fighting infection (our immune response). This post (and podcast) concentrates on the things we can all do to improve our chances of reducing the number of viral type illnesses we get (whether COVID-19 or the common cold).
This post and podcast were first published on our parent site, St Emlyn’s Blog. Professor Simon Carley interviewed two experts: Dr John Rogers (consultant in Sport and Exercise Medicine) and Dr Nathan Lewis (a leading performance nutrition scientist) and you can hear the interview here.
The main messages are beautifully summed up in this cool infographic (which you can print out). Although much of the research was done in elite athletes it seems sensible to give it a try, and there’s no evidence that it can do any harm.
Dr John Rogers is a Consultant in Sport & Exercise Medicine at Manchester University NHS Foundation Trust. He also works as Medical Director at the Manchester Institute of Health and Performance and as a Visiting Professor in Sport & Exercise Medicine at Manchester Metropolitan University.
