What does secondary effect mean, and what does SAE mean in medicine

Secondary effect refers to the use of cold or heat for more than a certain period of time, producing the opposite effect of physiological effect, this phenomenon is called secondary effect. For example, hyperthermia can dilate blood vessels, but after 30 to 45 minutes of continuous heat, the blood vessels will constrict. Similarly, after 30 to 60 minutes of cold use, the blood vessels dilate, which is a defensive response caused by the body's defense to avoid prolonged use of cold and heat to damage the tissues.

Therefore, there should be an appropriate time for cold and heat therapy, 20 to 30 minutes, and if it is necessary to use it repeatedly, the interval should be 1 hour in between, so as to prevent secondary effects from counteracting the physiological effects.
