尽管许多人不太习惯坐式便器解大便,但年龄大的老人,尤其是患有心脑血管疾病(如冠心病、高血压等)的老年人,采取坐位排便比蹲位更安全。 这是因为,老年人生理功能衰退,下肢血脉不畅,肌力不足,久蹲容易使双腿发麻和疲乏,特别是患心脑血管疾病时,血压调节功能减弱,血管的脆性增加。 Although many people are less accustomed to toilet stools, elderly people, especially those with cardiovascular and cerebrovascular diseases (such as coronary heart disease and high blood pressure), are more likely to have defecation than squatting. This is because the elderly decline in physiological function, poor blood flow in lower extremities, lack of muscle strength, squat easy to make legs tingling and fatigue, especially in cardiovascular and cerebrovascular diseases, blood pressure regulating function weakened, vascular fragility increased.
