Body Temperature Plays Greater Role than Metabolism in Lifespan, Study Shows

据中国科学院研究人员介绍,体温可能是比代谢率更加果断的寿命调制。

如果您希望静置更长时间,您可以更好地实现这一点,以便在您的身体温度上关注比新陈代谢更多。该结论是基于刚刚发表在自然新陈代谢的研究中的研究结果。

The research was led by scientists from the Chinese Academy of Sciences’ Shenzhen Institute of Advanced Technology (SIAT). Other researchers from Wenzhou University and the University of Aberdeen were also involved in the study.

快速快速,愚蠢

The popular belief is that there is an inverse relationship between living fast and maximum lifespan. In a more general sense, living fast is linked to risky lifestyle choices that often lead to premature deaths.

The cause of a shorter lifespan in the biological sense is different from the regular perspective. “Live fast, die young” has more to do with metabolism. Scientists have observed that animals having elevated metabolic rates are more like to die quicker than those with low rates.

It is, however, not very clear how metabolism affects lifespan in some species. For instance, exercise is one of those things that are believed to promote longevity, but it is known to ramp up metabolism.

There is a link between body temperature and metabolism. Low body temperatures usually go with low metabolic rates. This trend has made it hard to clearly figure out how metabolism impacts lifespan.

Caloric restriction and some other interventions that lead to lower metabolic rates seem to increase lifespan, based on research. However, it was not clear whether it was low metabolic rates or the associated lower body temperatures that prolonged lifespans in mice on caloric restriction.

温度和寿命

目前研究的研究人员希望在新陈代谢和体温之间找出哪些对寿命增加的至关重要。为此,他们依赖于代谢速率和温度沿不同方向进行的设置。

The team observed shortened lifespans in mice and hamsters after exposing them to high temperatures. Metabolism dropped while body temperatures went up at the peak of the thermoneutral zone.

“我们发现将啮齿动物暴露在这些条件下缩短了他们的寿命,”SIAT的教授John R. Speionman表示,他是一项研究合作作者。“较低的新陈代谢并没有延长他们的生命,但较高的温度缩短了它。”

When the animals’ body temperatures were lowered using small fans, their metabolism was not affected. But the effect of high temperature on lifespan was reserved.

The researchers said their findings suggest there may be a need to replace the saying “live fast, die young” with “live cold, die old.”

它们很兴奋,发现减少体温而不改变代谢率促进更长的寿命。他们说,这表明体温对寿命的影响更高,而不是代谢率。
