They found that “glymphatic transport was most efficient in the lateral position” — on their side.

研究发现，“侧卧位时，类淋巴的传输最为高效”——也就是侧躺着睡。

Moving on, to further evaluate sleep positions that promote good sleep quality, the position should be good for glymphatic transport.

继续来看，为了进一步评价提升睡眠质量的睡姿，这种睡姿应该有助于类淋巴的运输。

Scientists found something called the glymphatic system, a clean-up mechanism that removes this buildup and is much more active when we're asleep.

科学家们发现了一种叫glymphatic system 的脑部淋巴系统，一种能清除这些积聚物的清扫系统，当我们睡觉的时候这个系统更加活跃。

So, I figure a sleep posture that promotes good sleep quality would have to (1) Prevent snoring and (2) at least not impede the glymphatic system.

一能防止打鼾，二能至少不妨碍类淋巴系统的运作。

A hallmark of Alzheimer's disease is the build up of a peptide called amyloid beta, and the glymphatic system helps clear this stuff out of the brain.

阿兹海默症的一个特点是一种叫做β淀粉样蛋白的缩氨酸的累积，而类淋巴系统则有助于将这种物质清除出大脑。

The research on sleeping position affecting glymphatic transport is very limited, but this 2015 study had rodents sleep on either their side, back or stomach and were monitored via magnetic resonance imaging.

有关影响类淋巴传输的睡眠姿势的研究非常有限，但在这项2015年的研究中，啮齿动物分别侧卧、仰卧和趴卧，并用磁共振成像进行监控。
