1. Stimulate the palm with a hair dryer. Use a hair dryer to send warm air to the palm every day, from far and near, and then from near and far, repeatedly six or seven times, to stimulate the palm, the back of the hand and nails, and eliminate physical fatigue and tension. 2.

Stimulate the palm with a comb. After combing your hair every day, gently pat the whole palm with comb teeth for 2 to 3 minutes to adjust the visceral function.

3. Stimulate your palm with a toothpick. Take ten toothpicks, tie them into a bunch with a rubber band, and then stimulate your palms and nails with both ends, which can promote blood circulation. When using toothpicks, pay attention to the wide contact surface, and don't use too much force, otherwise it will easily stab the skin.
