It turns out that during the first few minutes (say, up to about thirty) after the onset of a stressor, you don’t uniformly suppress immunity—you enhance many aspects of it (phase A on the accompanying graph). This is shown with all realms of immunity, but in particular for innate immunity. This makes sense—it may be helpful to activate parts of your immune system that are going to make some swell antibodies for you over the next few weeks, but it makes even more sense to immediately activate parts of the immune system that are going to help you out right now.
