Exercise, Immunity, and COVID-19

Exercise, Immunity, and the COVID-19 Pandemic

Four crucial ways to fight germs (and boost your immune response) during the coronavirus outbreak.

The immune system is a biological structure that responds to disease by identifying and killing pathogens and tumor cells. It detects a variety of agents and distinguishes them from the body's own cells and tissues in order to function properly. This system is a truly remarkable line of defense that naturally occurs within all of us to protect the human body.

Exercise is proven to have a deep impact on the functioning of the immune system. Yes, exercise stimulates the immune response and can indeed have a positive effect on our ability to stay safe. 

The COVID-19 pandemic has raised some questions about how exercise can protect us by boosting our immune response. With the lack of access to gyms - and to some degree, public parks - the issue has become more urgent than ever before. The negative impact that social isolation has on the immune system is also crucial to consider. Cortisol levels, for example, are elevated during such times, and can inhibit critical functions of the immune system. How do we proceed?

When we are stressed, the ability of our T-cells to multiply in response to infectious agents, is markedly reduced; as is the ability of certain effector lymphocytes (e.g., NK-cells and CD8+ T-cells) to recognize and kill cells, in our body, that have become cancerous or have been infected with viruses. It is also vitally important that our immune cells maintain their ability to redeploy, so that they may ‘patrol’ vulnerable areas in our body (i.e., the upper respiratory tract and the lungs) to prevent viruses and other pathogens from gaining a foothold.

This process is also important to minimize the impact of the virus and to expedite viral resolution should we become infected.

Each bout of exercise, particularly whole-body dynamic cardiorespiratory exercise, instantaneously mobilizes literally billions of immune cells, especially those cell types that are capable of carrying out effector functions such as the recognition and killing of virus-infected cells. The mobilized cells firstly enter the blood compartment from marginated vascular pools, the spleen and the bone marrow before trafficking to secondary lymphoid organs and tissues, particular to the lungs and the gut where increased immune defense may be required. The immune cells that are mobilized with exercise are primed and ‘looking for a fight.’ Their frequent re-circulation between the blood and tissues functions to increase host immune surveillance, which, in theory, makes us more resistant to infection and better equipped to deal with any infectious agent that has gained a foothold.
