乐观应该是心脏最喜欢的性格。

乐观应该是心脏最喜欢的性格。

近日,一项纳入15项研究涉及近23万名人的研究再次证实乐观的人心脏更健康,乐观可以预防心脏病发作、中风和过早死亡。

研究者发现,与悲观主义者相比,乐观主义者患心脏病风险要低35%,死亡风险降低14%。

研究者说,这种身心联系在所有年龄段都存在,乐观主义可能是一种人生资产。

研究还发现,一个人的想法越乐观,他患心脏病或死亡的风险就越小。

为什么积极、乐观的人生态度直接或间接地有助于预防疾病。

研究者分析,乐观的人更善于解决问题,能更快地找到解决办法,他们更容易实现目标,他们也更关注自身的健康。

此外,乐观主义者有更健康的生活习惯,,可能有良好的饮食和锻炼习惯,他们不太可能吸烟。

越来越多的数据也表明,乐观可能有直接的生物效益,而悲观可能损害健康,这种生物学联系已经被证明与其他一些心理危险因素有关,如抑郁症。

作者认为,乐观也可能通过降低炎症和改善新陈代谢发挥神奇作用。

同期述评中也指出,这与更多的体力活动、更健康的饮食和一系列其他健康的生活方式行为有关,乐观促进健康的机制涉及生物学和行为学机制。

研究者分析了15项研究,包括229 391名参与者,其中10项研究报告了心血管事件的数据,9项研究报告了全因死亡率的数据。平均随访13.8年(2~40年)。
