This is less of a question than a comment. I am always reminded when I take a ride on my Can Am Spyder motorcycle how important hydration is to breathing. We rode about 180 miles yesterday and the 90 mile ride home was at temps of 93 degrees. It has become increasingly the case that while I am perfectly comfortable and able to breathe well while riding that when I get home and get off the bike my breathing is difficult. I am convinced that this is the result of becoming dehydrated by the heat and the air passing around me at 60 MPH for an hour or so. You lose a tremendous amount of fluid in these situations in spite of the fact that I always carry at least 1 bottle of water with me. I got home really SOB and worn out yesterday, drank 12 oz of water, took a breathing treatment, a cool shower and then another bottle of water and soon felt like a million dollars again.
I know its hard to imagine with the brutal winter in the North but spring and summer are on the way. Remember to hydrate constantly especially in warm weather or when you are active, it will make a big difference in how you feel and how you breathe.
As an RT once told me hydrate until your urine is clear, the darker yellow it is the more you need to drink! Stay safe and well!
