一、人体节律取决于生物钟你或许有这样的体会,当你欲办某种事情时,会在预定的时间里突然想到或从沉睡中醒来,这是受生物钟调节的结果。事实上,人无时无刻不在接受它的支配,晚间产生睡意,早晨主动清醒,体温在一天中发生有规律的变化:凌晨最低,黄昏达到高峰。就心脏跳动和人体的吸呼来说也是如此,在正常情况下,心脏每分钟跳动约七十次,剧烈运动时,心率增加,可达百余次;正常情况下呼吸频率为16——20次,而在运动时则明显加快。再如,女子月经周期为三十天左右,行经前后会出现一些生理变化。所有这些,无不与生物钟调节有关。
First, the human body rhythm depends on the biological clock You may have such experience, when you want to do something, it will suddenly think of or wake up from the sleep in a predetermined time, which is regulated by the biological clock. In fact, people accept their domination all the time, drowsiness in the evening, active wakefulness in the morning, and the body temperature changes regularly throughout the day: the lowest in the early morning and the highest in the evening. The same is true for the heart beat and the body’s inhalation. Under normal circumstances, the heart beats about seventy times per minute, and when strenuous exercise, the heart rate increases to more than one hundred times; under normal circumstances, the respiratory rate is 16-20. Times, but significantly faster during exercise. Again, the women’s menstrual cycle is about 30 days, and some physiological changes will occur before and after the menstruation. All these are all related to the regulation of the biological clock.
