A study, conducted on mice, found that the repeated stresses of regular exercise strengthens the body’s immune system.

The mice were separated into 2 groups: one group swam for 10 minutes/day, 5 days/week for 3 weeks (equivalent to a 30-minute run in humans) and the other group did no exercise.

Both groups of mice were infected with drug-resistant Staphylococcus aureus strain 3089 (DRSA). A bacterium that typically causes skin and lung infections in humans.

The swim-trained mice exhibited a more refined and effective immune response to the Staph infection when compared to the unexercised mice.

These findings suggest that in these model mice, regular exercise strengthens immune system responses, potentially preventing or mitigating infectious disease.” – Lee JK, Luchian T, Park Y

Of course, mice are different from humans, but the researchers strongly believe that long-term, regular exercise can have a positive effect on how your body reacts to viral infections like colds and flus.

Yet another reason to be physically active even throughout the winter season!
