If you can’t seem to catch enough Z’s during the week, you’re not alone. But bad things happen to your body when you’re sleep-deprived, not least of which is weight gain. Well, here’s some good news: Sleeping in on the weekend to make up for sleep lost during the week is 1 with lower body mass index (BMI), according to a study published in the Oxford University Press journal Sleep.

The researchers, a collaboration of scientists based in Boston, Massachusetts, and the Republic of Korean, sought to determine if what they refer to as “catch-up sleep” 2 body mass index (BMI) in the general population. To do so, they conducted face-to-face interviews of a random sampling of 2,156 adults, comparing their sleep habits with their BMI scores. The 932 participants who slept in — “catch-up sleepers” (people who sleep longer on the weekend than on weekdays by approximately two hours) had a(n) 3 lower BMI than the other subjects. What’s more, every additional hour of catch-up sleep was linked with a decrease in BMI.

As to why sleeping in on weekends can lead to weight loss, one of the study co-authors, Robert Thomas, MD, MMSc, of the Division of Pulmonary, Critical Care and Sleep Medicine, Department of Medicine at the Beth Israel Deaconess Medical Center in Boston, 4 Reader’s Digest of the “substantial(大量的) experimental and epidemiological(流行病学的) data that short sleep contributes to weight gain.” He notes, “our best 5 as researchers are that there are balances to be kept, and the body can adjust and 6 within reason. Catch-up sleep allows the basic balance to be maintained.”

Although the study showed significant differences in BMI with the 7 of two or more hours of catch-up sleep, Dr. Thomas points out that there are “substantial individual differences,” such that the benefit we get from those extra hours will vary 8 on how much sleep each of us generally needs. “To determine your optional sleep, you can track the time spent sleeping on nights when there is no need to wake up to an alarm,” suggests Liza Baker, a health coach at Simply Health Coaching. That tells you about how many hours of sleep your body likes to get, since it 9 greatly across the population, from just 4 to 5 hours to 9 to 10 hours.

So can you actually lost weight by sleeping in on the weekend? Only if you’re paying off a sleep 10 from the week, according to the result of this study. It helps if you’re also eating less, Dr. Thomas adds.

【题目】Get a taste of the amazing world of engineering

Do you want to help shape the future of everything from entertainment and transport to sport and the environment? Then you might want to think about the fascinating world of engineering. Tomorrow's Engineers Week is running 4-8 February 2020, and is the perfect time to get an idea of what engineering is all about.

Engineers are the people who use scientific knowledge, ranging from long-established scientific laws to cutting-edge discoveries, to solve problems and improve life for all of us. Tomorrow's Engineers Week aims to get young people interested in this exciting career. It also wants to change the way we think about engineers.

One place to find out more about engineers is the website thisisengineering.org.uk, where you can meet 16 young engineers with amazing and different jobs. There's Halvard, who builds farm robots; and Olivia, who uses her chemical engineering skills to create soaps and shampoos kind to the skin and the environment. Alice digs train tunnels deep underground. Michelle builds rides. As a child, she loved these thrilling rides. At the age of 14, she attended a lecture on roller coaster design, and then she realized that engineering was a great way to turn her passion into her career.

If you want to meet some inspirational engineers, ask if your school has signed up to take part in the Big Assembly (大型集会) on 6 February. Don't worry if not, though, you can check it out yourself afterwards on the tomorrowsengineers.org.uk website.
