研究發現 樂觀看法使人健康長壽

Researchers find that a positive view can do far more than raise one's spirits. It may actually improve health and extend life.
研究人員發現，樂觀的看法不僅可以振奮人們的精神，可能真的可以改善健康、延年益壽。

Studies have shown an indisputable link between having a positive outlook and health benefits like lower blood pressure, less heart disease, better weight control and healthier blood sugar levels.
研究顯示，秉持樂觀看法與降低血壓、更不易患上心臟病、改善對體重的控制和更健康的血糖水平等健康方面的益處之間，存在着不爭的聯繫。

In a study of more than 4,000 people 50 and older, Becca Levy and Avni Bavishi at the Yale School of Public Health found that having a positive view of aging can have a beneficial influence on health outcomes and longevity.
在一項針對4000名50歲及以上人士的研究中，耶魯大學公共衛生學院的貝卡·雷維和阿夫尼·巴維希發現，積極看待衰老可以對健康狀況和壽命產生有益的影響。

Levy said two possible mechanisms account for the findings.
雷維稱，或許可以用兩種機制來解釋箇中原因。

Psychologically, a positive view can enhance belief in one's abilities, decrease perceived stress and foster healthful behaviors.
從心理上說，積極的看法可以增強人們對自身能力的信心，減少能感知到的壓力，培育健康的態度。

Physiologically, people with positive views of aging had lower levels of C-reactive protein, a marker of stress-related inflammation associated with heart disease and other illnesses, even after accounting for possible influences like age, health status, sex, race and education than those with a negative outlook. They also lived significantly longer.
從生理角度說，即使考慮到年齡、健康狀況、性別、種族和教育等可能的影響因素，積極看待衰老的那些人體內的C反應蛋白水平也較低——C反應蛋白水平是與心臟病等疾病有關聯的壓力相關炎症的風向標，而他們的壽命也要長得多。
