Too Much Exercise Can Shut Down Your Immune System

There is a phase called “the immune swoon” which takes place after heavy bouts of exercise can be explained at the cellular level. Intense physical activity has been found to suppress a number of the immune system’s key molecular components.

 

These components include reduce secretion of sIgA in the Saliva. An antibody that plays a critical role in mucosal immunity, SIgA is found in the mucous membranes of the mouth, nose, throat and lungs. It is believed that low SIgA is partly responsible for findings of increased URTI (Upper respiratory tract infections) risk in athletes following heavy exercise.

 


Other immune cells that can take a hit include phagocytes, natural killer cells and macrophages, the innate arm of the immune system is especially impacted. In addition, intense training increase’s inflammation and oxidative stress which also suppress immunity.

 


This suppressed immunity period opens a window of vulnerability and gives bacteria the opportunity to grow unimpeded and cause infection. This window is only temporary but can last from 3 to 72 hours.

 


Taking Essiac as part of your regular daily regime can help your immune system to bounce back quicker after an intense workout.
