When you exercise, you are activating your lymphatic system which stores all the garbage
(dead cells and toxins) - if this system is not emptied regularly you get a build up which can
cause you to feel ill. Exercise not only stimulates your lymphatic system but it also helps draw dietary and metabolic acids from your tissue, sweat helps eliminate acids and improves blood circulation.  

You must increase your oxygen intake which gives you energy and helps your blood flow.
Deep breaths help oxygenate your body as well.
