月经周期是指头一次月经开始到下一次月经开始 的天数。正常经期持续的天数范围为3-7天。很多女生在 经期都不上早操、课间操和体育课,她们认为行经时流 了许多的血,对身体伤害很大。其实月经是每个正常女 性很自然的生理现象,既然月经是人体正常的生理现象 而并非疾病,更谈不上对人体的伤害,那么按照常理而 言,即使月经来临时,也可以过和平常一样的生活,当然 也可以适当地做些运动。
The menstrual cycle is the number of days from the start of the first menstrual cycle to the start of the next menstrual cycle. The duration of normal menstrual periods ranges from 3 to 7 days. Many girls do not perform morning exercises, class breaks, and physical education classes during menstruation. They think that there is a lot of blood flowing during menstruation and they are very harmful to the body. In fact, menstruation is a very natural physiological phenomenon for every normal woman. Since menstruation is a normal physiological phenomenon of the human body and not a disease, let alone an injury to the human body, then according to common sense, even if menstruation comes, it can be normal. The same life, of course, can also do some exercise properly.
