answer:When you sit anywhere, ergonimically speaking, everything should be at 90 degree angles. Your bend at the waist should be 90 degrees, your bend at the knees should be 90 degrees with your feet flat on the floor. If that’s not the case and you spend an excessive amount of time sitting, that can contribute to your leg falling asleep. It’s also possible that you’re pinching something by sitting incorrectly, causing the right side to fall asleep. Try to always sit ergonimically if you feel uncomfortable. Worst case, see the doc and have him check things out with your circulation and such. and don’t tight-cuff your jeans… that’s not one of the 80s trends back in style again ;)
