I was able to exercise today. I did the elliptical machine for 30 minutes. However, about 2 hours after exercise I am always so cold. I have the heat up to 80 degrees and am wearing a sweater. I am wondering if this has anything to do with glycolysis, and glycogen depletion. I am looking it up and it seems to be a symptom of glycogen storage issues. I am assuming with us, it has to do with dysfunctional mitochondria and lack of oxygen. I can't find much information on this. I have forgotten why it is we get cold after exercise and I am wondering if someone can please refer me to an article about this.
