Doh! I'm sick. Just a nasty little cold but it's sideline me from working out. I so wanted to go on a short run, put in some gym time and swim tonight. But that is not going to happen. Someone suggested that I got the cold after the marathon cuz' "The marathon freaked out your immune system." So I looked it up on the wide world web and getting sick after a marathon is pretty common. Here is Runners World had to say:
When you push your body without interruption for more than 90 minutes, the stress hormones cortisol and epinephrine, which suppress immune function, gush out of your adrenal glands. Inflammatory cytokines, neutrophils, and monocytes (red-flag markers of physiological stress) take over your bloodstream, while your virus-fighting T cells and "natural killer cells" go into hiding. None of this is good. It doesn't make you sick on the spot, but for at least a few hours after the run, it makes your body as inviting to "bugs"
So I've been sleeping and eating. Hopefully over the weekend I'll be me again and at least swim a bit. But I am not going to push it!
