所谓生物节律,是各种生物体内的诸多生理活动,因外部环境的节律变化(如地球自转形成的尽夜),呈现出周期性变化。
一个尽夜中,人的体温、脉搏、血压、氧耗量、激素的分泌水平都在变化,有时还呈现周期性。
So-called biological rhythm, many physiological activities across a wide variety of organisms, due to the external environment of rhythm changes (such as the rotation of the formation of the night), presents a cyclical change.
A all night, the body's temperature, pulse, blood pressure, oxygen consumption, the secretion of hormone levels are changing, sometimes periodic.
