I woke up today with that familiar feeling: a tingle in my throat felt when I swallow which is always always my first indication of a cold/sickness/infection coming on.
My sensei always told me that the best thing to do to a cold is to sweat it out.... so sweat I do. Upon my realization, I headed straight downstairs for some cardio.
Exercise is fantastic for the immune system. Going to a gym can be risky because of all the germs floating around (seriously, how often do you think those dumbbells get cleaned?). But I personally found a marked difference in the number of times I got sick in a year when I started exercising. I used to get sick maybe 5-6 times, and now that number is down to 2-3 (one summer, and one winter cold).
If nothing else, it usually helps to clear the sinuses and headache, and distract your body from those muscle aches and pains. I've known a few people who claim that the workouts they do when they're sick are amongst the best workouts they have. You just push yourself a little bit harder to kick the hell out of that cold!!
So we'll see. I took some Vitamin C today, hit the gym after work, ate at least 8 servings of fruit and vegetables, and made sure to get some sunlight. I don't expect to cure this cold altogether, but hopefully all these efforts will help to minimize the damage.
