60秒科学:Morning-Light-Exposure-Tied-to-Lower-Weight

听力内容:

60秒科学节目(SSS)是科学美国人网站的一套广播栏目,英文名称:Scientific American – 60 Second Science,节目内容以科学报道为主,节目仅一分钟的时间,主要对当今的科学技术新发展作以简明、通俗的介绍,对于科学的发展如何影响人们的生活环境、健康状况及科学技术,提供了大量简明易懂的阐释。

Light might make you a lightweight in a good way. It’s been known that bright light in the morning can reduce appetite and body weight. But that fact did not prove that light has a direct effect on weight. Early morning exposure to light could just be a marker for a regular sleep cycle, which is also associated with a healthy body weight.

The question was thus whether light exposure was associated with weight regardless of sleep patterns.

To find out, researchers had 54 adults record their diet and sleep for a week. The subjects also wore sensors that monitored the timing and intensity of their light exposure.

And independent of sleep habits, the participants’ body weight corresponded to when they saw the light even dim light, with just half the intensity of sunlight on a cloudy day. The study is in the journal PLoS ONE.

So early to bed and early to rise appears to indeed make you healthy. Jury’s still out on whether it also makes you wealthy and wise.
