question: I think I have really bad blood circulation because of many reasons. A) I always feel the temperature more than other people. In the winter, I'm always cold, no matter how many layers I wear. In the summer, I tend to overheat or dehydrate because I sweat so much (gross I know, sorry). B) My legs and arms fall asleep easily. If i sit still for more than a minute or two, I get really bad pins and needles that take a long time to go away or sometime I'll wake up in the middle of the night because I sleep in odd positions and my arms have been above my head for awhile and it feels as if there is no blood in my arms at all. They feel like Harry Potter's arm after that Lockheart guy tries fixing his broken bone - loose, numb, like my muscles can't move anymore, yet my hand and arm functions fine.
