Early to bed and early to rise, makes a man healthy, wealthy and wise.

—Benjamin Franklin

早睡早起使人健康、富有和聪明。

——本杰明·富兰克林

I’m sure a lot of subway riders are skilled nappers, but this car seemed to be particularly talented. Going over the Brooklyn Bridge on a recent morning, just as the sun was coming up,a row of men in nearly identical black suits held on to the straps with their eyes closed. Thei necks were bent at the slightest of angels, like a row of daises in a breeze and as the car clanged over the tracks and the sun pierced through the grimy train windows, it finally dawned on me that they were all sound asleep. Not even the bumps and the light could stop them from sneaking in 15 more minutes of shut-eye before work.

We take it for granted, but most people have to wake up for work (or school or other morning obligations) before they want to. Sleeping is treated as a cherished luxury—it’s somehow become normal that people wake up still exhausted and anything but is a notable exception.

But rising before the body wants to affects not only our mood and energy, but brain function as well, says an article from The Atlanti.①

“The practice of going to sleep and waking up at ‘unnatural’ times could be the most prevalent high-risk behavior in modern society,” the article quotes Till Roenneberg, a professor of chronobiology at the Institute of Medical Psychology at Ludwig-Maximilians University of Munich in Germany, as saying.

According to Roenneberg’s groundbreaking study recently published in Current Biology,about one-third of people living in first-world countries are required to wake up two hours before their circadian clocks, or “natural waking times,” tell them to, and 69 percent of people have to wake up one hour before their bodies would like them to.

Sleepless night have serious downsides. Although there’s no universal rule for how long we should all be sleeping, it’s becoming increasingly clear that staying up late and waking early can cause serious problems.②It’s not just repeated sleep deprivation that harm people. Just one restless night can seriously affec us in the morning.

Side effect from missing sleep include:

If all these still can’t motivate you to get enough sleep, consider this: Not sleeping enough makes you fat. Sleep deprivation compromises your body’s ability to metabolize carbohydrates and control food intake.③When you sleep less you eat more and have more difficul burning the calories you consume.
