日常生活中一些不良习惯和生活方式，常为冠心病等心血管疾病埋下危险的种子。生活习惯是可改变因素，培养健康的生活习惯可以远离冠心病。

●3个半分钟：一些老年人发生在卫生间的心脑血管意外，与夜间突然起床入厕、体位改变过快，造成一时性心脑供血不足有关。因而提倡“3个半分钟”的保健方法：夜间醒来时，应先在床上躺半分钟，坐起来双脚放在床沿下坐半分钟，再以双手撑住床头站立半分钟后行走。

●午睡半小时，“冠心病”少三成：每日午睡半小时者比不睡者冠心病死亡率少30%，其原因与午睡时血压下降、心率减慢，使白天的血压曲线出现一段低谷有关。尤其是肥胖型人群、60岁以上的老人，午睡更为必要。

●适度运动，带病延年：生命在于运动。运动锻炼是改善心脏功能最基本、最重要的方法之一，可以选择有氧运动、抗阻运动、柔韧性运动等运动方式。

●谨防“魔鬼时间”：一天24小时中，早晨6至11时是急性心梗、猝死的高峰时间，被称为“魔鬼时间”，病情较重的冠心病患者，晨起宜提前服药，上午不宜安排过量活动。晨起锻炼时间以7至8时为宜。
