为什么睡过头反而更疲倦?

身体的内部节奏是提前设定好的，会根据人体内在的生理起搏器、下丘脑部的一系列神经簇还有大脑控制饥饿、口渴和出汗的那一小部分基元来共同作出决定。在昼夜节律系统的生物钟中，生理起搏器主要根据眼部所接收的光线来判断清晨的时间，然后向身体的其他部分发送化学信号告知该时间。

Scientists believe that the pacemaker evolved to tell the cells in our bodies how to regulate their energy on a daily basis. When you sleep too much, you’re throwing off that biological clock, and it starts telling the cells a different story than what they’re actually experiencing, inducing a sense of fatigue. You might be crawling out of bed at 11am, but your cells started using their energy cycle at seven. This is similar to how jet lag works.

科学家们相信：进化后的生理起搏器会告知身体细胞，每日如何管理调节自身能量。如果你睡得过久，就会脱离正常的生物钟，导致生理起搏器对身体细胞发出的讯号与以往实际体验中的不同，包括对疲劳的感觉。你可能在早上11点才从床上爬起来，但是你的身体细胞从早上7点就开始进行能量循环了。这与时差所导致的情况十分相似。

But oversleep isn’t just going to ruin your Saturday hike. If you’re oversleeping on the regular, you could be putting yourself at risk for diabetes, heart disease, and obesity. Harvard’s massive Nurses Health Study found that people who slept 9 to 11 hours a night developed memory problems and were more likely to develop heart disease than people who slept a solid eight. (Undersleepers are at an even bigger risk). Other studies have linked oversleep to diabetes, obesity, and even early death.
