英国《每日邮报》报道,哈佛大学公共卫生学院一项新研究发现,心态乐观有助于降低血脂水平。研究发现,中年乐观者“好胆固醇”(HDL,高密度脂蛋白)水平更高。好胆固醇可降低“坏胆固醇”(LDL,低密度脂蛋白)水平,对心脏具有保护作用。冷静乐观还可以降低甘油三酯水平。甘油三酯水平过高会导致血管硬化。新研究负责人茱莉亚·波伊博士及其同事完成的早期研究结果显示,乐观与心脏病危险较低之间存在关联。因此他们决定调查乐观或悲观与胆固醇之间是否存在独立关联。新研究中,哈佛大学科学家对来自美国中年研究项目的数据进行了梳理分析。该研究对990名40~70岁参试 A new study by the Harvard School of Public Health found that optimism can help lower blood lipids, the Daily Mail reported. The study found that middle-aged optimists “good cholesterol ” (HDL, high-density lipoprotein) level is higher. Good cholesterol can reduce the level of “bad cholesterol” (LDL, low density lipoprotein), has a protective effect on the heart. Calm optimism can also reduce triglyceride levels. Triglyceride levels can lead to hardening of the arteries. The results of an earlier study done by Dr. Julia Poy, the new head of research, and colleagues showed that there is a link between optimism and a lower risk of heart disease. So they decided to investigate whether there was an independent association between optimism or pessimism and cholesterol. In the new study, Harvard scientists analyzed the data from the American middle-aged research project. The study of 990 40 to 70-year-old test
