Rubbing hands can be long or short, as long as both hands are free. Rubbing your hands for a little longer will make your hands feel warm.
Hold out your hand. Stretch out your hands and open and close several times in a row to relax the tendons, muscles and joints on your hands and accelerate blood circulation.
Massage your fingers. Gently knead with the knuckles of your fingers and press into a circle. When you reach your fingertips, hold your fingers and gently lift them, then release them. Then massage other fingers in the same way. If you use massage essential oil, it will be more comfortable and effective.
