The temperature of the bath water is higher, so there is a lot of water vapor, and water vapor is in the gas phase，Its molecular radius is small, easy to penetrate from the watch shell gap, when the temperature drops.After it will recondense into liquid droplets, easy to cause the watch internal circuit short circuit, Damage the watch circuit board, and then damage the watch. Why does blood pressure value deviate from blood pressure monitor? Deviations between watches and sphygmomanometer measurements are determined by a variety of factors, sphygmomanometer It was measured in the cerebral artery, and the watch was measured in the two main branches of the arterioles,The normal difference between aortic and arteriolar blood pressure measurements is three to fourTen; If you use a watch and a sphygmomanometer at the same time, because of the flow in the arteryIt's centrifugal blood, and the sphygmomanometer will measure it below the center of your elbowUnder pressure, the blood is temporarily unable to flow smoothly to the branches of the arteries below; The blood vesselsThe increase of tension will lead to greater deviations in the upper and lower blood pressure measurements.
