Scientists used to think that this was as a consequence of reduced immune function after prolonged exercise, in addition to increased exposure to infection as a consequence of the big crowds that marathons attract. But Our latest research shows that an individual's anxiety, stress and mood may play a job in whether or not they're more susceptible to getting sick after a protracted run or marathon.
In our first study, we asked 406 runners to finish questionnaires about their anxiety and mood within the months and days before running a marathon. We also asked them to offer saliva samples before and after the race.
The mouth is one among the essential routes of entry for the vast majority of viruses and bacteria that cause respiratory infections. The saliva samples allowed us to find out whether there have been signs that the defense systems that normally prevent these pathogens from entering the body (called mucosal immunity) were suppressed.
We then tracked their common cold symptoms over the 2 weeks following their marathon.
Runners who were more anxious on the whole and those that experienced greater mood distress before the race (similar to anger, frustration or stress) were more prone to have respiratory infections throughout the two weeks following the marathon. They were also more deficient in mucus immunity.
In one other study, we asked 45 adults to walk on a treadmill for an hour inside our laboratory. We asked them to finish questionnaires about their anxiety, stress and mood before completing the run. We also measured their mucosal immunity in saliva before and after the run.
Men with higher anxiety levels, stress levels and more mood disturbances were more prone to have decreased mucosal immunity than those with lower anxiety and stress levels before the run.
When examining the influence of stress, anxiety and mood on the immune response to an hour of running in women, the outcomes weren't so clear cut. There are many possible reasons for this – including aspects similar to hormone fluctuations, contraceptive use and the like Differences in immune response All are prone to have an influence, depending on the phase of the menstrual cycle. It will likely be essential to look at this for future studies.
Taken together, the findings from our studies suggest that people who find themselves more stressed or anxious before a run could also be more susceptible to getting sick or catching a chilly. This effect seems to use not only to marathon-length runs, but in addition to moderate-length runs of 1 hour.

These pathways connect the nervous system to the brain and play a job within the stress response. High psychological stress or prolonged exercise can suppress these axons and reduce immune function.
So when runners experience each psychological and physical stress, the consequences on the immune system could also be more significant than in the event that they were experiencing only psychological or physical stress.
