It is normal for the blood vessels in the head to beat. The arteries in the whole body are in a state of beating all the time because there are structures like vascular smooth muscle in the walls of the blood vessels that can contract to produce blood pressure, which is the driving force for the continuous flow of blood in the blood vessels. The fluctuation of blood vessels is related to the heartbeat. The head has less muscle and fatty tissue, and the blood vessels are more superficial and can often be touched with the fingers, such as the temporal area at the temples, where you can often feel the pulsation of the blood vessels with your fingers in line with the heartbeat. In the elderly, because of arteriosclerosis, the pulsation of the blood vessels is weakened, and when the blood pressure rises or when the emotion is excited, the pulsation of the blood vessels is significantly enhanced.
