In addition, exercise and emotional excitement will speed up the pulse, while rest and sleep will slow down. When you have a fever, your pulse will accelerate. Generally, every 20 times of increase, the corresponding body temperature will increase by about 65438 0 degrees Celsius.

Extended data
Formation and diffusion: due to the contraction and relaxation of the heart, the pressure in the artery rises and falls; Because the arterial wall is rich in elastic fibers, the rise and fall of arterial internal pressure can start from the aorta in the form of pulse wave, spread rapidly along the arterial wall to the branches of the artery, and finally reach the end of the arteriole.
Pulse wave propagation velocity and blood flow velocity are two completely different physiological phenomena. When the ventricle contracts and ejects blood to the aorta, the long blood column flows along the branches of the arterial system at a speed of 0.2 ~ 0.5 meters per second, and the velocity is the fastest in the aorta and the slowest in the arteriole capillary network, which can be slowed down to stagnation.
The propagation speed of pulse wave varies with the elasticity of each arterial wall. The aortic wall is rich in elastic fibers, so its expansibility and elasticity are the greatest, and the propagation speed of pulse wave is the slowest, generally 3 ~ 5 meters per second.
Medium-sized arteries, such as radial artery and femoral artery, have less elastic fibers, less expansibility and elasticity, and the pulse wave travels faster, about 7 ~ 10 meter per second. The elasticity of arterioles becomes smaller and the propagation speed is obviously accelerated, which is about 15 ~ 35 meters per second. When the artery is hardened, the pulse wave propagates faster.
