“紧张是一种使人痛苦或有害的力量,它引起精神和身体的痛苦与劳累。”在较短时间中,即使情绪的、应激性的刺激亦能使一些易患因素达到异常水平,或使之增强。低温或增加工作紧张度等刺激,能在短时间内使胆固醇升高100毫克％之多。胆固醇水平在应激时期可持续升高,以后慢慢恢复。血压能随情绪紧张的强弱而升降。动物实验显示,如情绪紧张持续存在,血压可长期升高,其后虽去除紧张性刺激,血压仍不能恢复正常,说明已发生永久性调节异常。
“Tension is a painful or detrimental force that causes mental and physical pain and exertion.” In a relatively short period of time, even emotional and stressful stimuli can bring about some abnormalities in risk factors, Or make it stronger. Low temperature or increase work stress and other stimuli, can raise cholesterol in a short period of time as much as 100 mg%. Cholesterol levels in the period of stress can continue to rise, then slowly recover. Blood pressure can rise and fall with the strength of emotional stress. Animal experiments show that if the persistence of emotional stress, blood pressure can be long-term increase, although after removing the tension stimulation, blood pressure still can not return to normal, indicating that permanent adjustment has occurred abnormalities.
