Finger stretching

So, we've learned about finger stretching. Clench your fist tightly for about 20 to 30 seconds. Then, slowly spread your fingers out; repeating this action improves blood circulation in your hands. They say the "jam-jam" (hand-slapping) that young children do is good for their health!

It is said that spreading your hand flat on a flat surface and repeatedly lifting and lowering your thumb, index finger, middle finger, ring finger, and little finger in that order is also good for your health and hand beauty.
