Ten fingers are connected to the heart, and there are many acupoints on the hand, which dominate the stomach at the lower part of the palm and the little finger. If you rub it there for a long time, your appetite will increase. If you stimulate it hard, you may have stomach cramps. It may be exaggerated, but it also contains some Chinese medicine theories. I suggest you rub your hands more, pat harder and take longer. This can promote blood circulation, strengthen basal metabolism, and have an effect on fat burning.
