Sleep, considered a luxury by many, is essential for a person’s wellbeing. Researchers have found that insufficient sleep increases a person’s risk of developing severe medical conditions. such as obesity, diabetes, and cardiovascular diseases. Now, a new study by Boston’s Massachusetts Institute of Technology ( MIT) has found that getting sufficient sleep is also the key to improving academic performance.
Jeffrey Grossman, who led the research. was not trying to find the link between sleep and grades when he handed out Fitbits to the 100 students in his introduction to Solid-State Chemistry class. Instead, the professor of Computational Materials Science hoped the popular wrist-worn device which. tracks a person’s activity 24/7, would show a connection between physical exercise and academic achievement.
However, the study, published in the journal “Science Learning” on October 1, 2019, discovered a surprising insight. Then was a straight-line relationship between the average amount of sleep a student got and his/her grade on the 11 quizzes, three midterms, and the final exam administered during the semester.
Even more interesting, it was also not sufficient for students to just head to bed early the night before a test. Instead, it’s the sleep you get during the days when learning is happening that matters most.
The time students went to bed each night was similarly important. Those who went to bed in the early hours of the morning performed poorly, even if the total sleep time was the same as a higher - performing student. “When you go to bed matters. Grossman says. If you go to bed after 2, your performance starts to go down even if you get the same seven hours. So, quantity isn’t everything.”

A call came into Jimmy Gilleece’s bar. A newly married woman, who had spent the afternoon at his bar, couldn’t find her wallet. She didn’t care about her ID, credit cards, or 150 in cash-but her wedding ring was inside.
Gilleece, 42, didn’t like the idea that a theft could have occurred at his place. So he determined to find the wallet. He spent hours on videos from surveillance (监控) cameras, watching the woman’s every step in the bar. Within minutes, a young man approached the bar, put something in his pocket, and walked off.
Gilleece posted a clip (视频片段) on the bar’s Facebook page to find out who the young man was. Within hours, Gilleece got a text from 17-year-old Rivers Prather, who said he’d done it because he hadn’t eaten in two days. He said he saw the ring but thought it was fake, so he took the money and threw the wallet into the ocean. Then he bought a sandwich.
Gilleece told the teen to meet him at the docks (码头). There they talked a lot and Gilleece knew that Prather was from a poor family. Seeing the teenager’s small build, Gilleece thought he was more of a kid than a criminal. However, because of the missing ring, Prather could be put into prison.
Gilleece decided to help the kid. He hired two local divers to search the waters where the wallet had been thrown. More than an hour passed, with no sign of the ring. Gilleece grew worried. And then a diver popped up. In his hand was the wallet, and inside was the ring. When Gilleece called the wallet’s owner, she burst into tears and immediately dropped the charge against Prather for stealing the ring.
