问:我是一名中年男子,身体健康,夫妻性生活和谐,可近几年来每次房事后都感到浑身酸痛,尤其是腰背部,请问这是什么原因?是不是病?答:这是一个十分普遍而又不被人们所重视的有趣的生理问题。对于房事后所出现的肌肉酸痛,一般均属正常生理反应。人在性活动中,有两个明显的生理反应,一是血液循环加快、血管充血;二是肌肉活动强烈。当性反应开始时,全身有关肌肉敏感性增强,然后有规律地反复收缩。随着性紧张度的提高,局部有关肌肉强直性收缩,一些肌群还可出现不随意性紧张和收缩;随着性兴奋的高涨,遍及浑身的肌群收缩剧烈。由于高潮期对浑身肌肉群痉挛性收缩几乎难以察觉,常到同房后的第二天才感到浑身酸痛。因此,房事后浑身酸痛是肌肉群 Q: I am a middle-aged man, with good health and a harmonious sex life of husband and wife.
