Our world has changed immeasurably this year due to the Covid-19 pandemic, and we all know that handwashing, wearing face coverings and social distancing can help prevent transmission of the SARS-CoV-2 virus (which causes Covid-19 infection).
There are also measures we can all take to reduce our chances of becoming severely ill from Covid-19 if we become infected with the virus.
Moderate-intensity exercise has positive effects on our immune system, increasing the circulation of immune factors that help us fight diseases.1,2 It is likely that given the positive effects of moderate intensity exercise on our immunity, being physically fit reduces our chances of being severely affected should we become infected with Covid-19.3
Risk factors for severe illness with Covid-19 infection include:
Exercise helps prevent most of the above conditions either directly or indirectly, and if an individual is already affected by any of the above conditions, exercise forms part of the treatment. For example, if you have high blood pressure, a regular programme of exercise may reduce your need for blood pressure medications. The same applies for regular exercise in a person with diabetes; the need for medication can potentially be reduced.

A Consultant in Sport and Exercise Medicine can help if you want to make changes to your lifestyle to improve your physical fitness and reduce your risk of conditions such as cardiovascular disease, high blood pressure, diabetes, and even some cancers – and being severely affected by Covid-19 infection.
An important point to note is that there is a sweet spot and that too much exercise – overtraining – can have negative effects on the immune system.5 Most people are not affected by overtraining but a relentless, monotonous programme of exercise with inadequate rest periods and inadequate fuelling may result in overtraining. If you are concerned you may be affected by overtraining, a Consultant in Sport and Exercise Medicine can also help.
