It seems we're always being told to get more sleep. Studies suggest spending less time on sleep can lead to obesity(肥胖) and even cancer. You might even find yourself with a head full of false memories. But rarely does science explore the dark side of sleeping too much. That's because few of us in today's busy world have the luck of exploring that option.
In an August 2018 study, published in the Journal of the American Heart Association, researchers researched the sleep patterns of those "fortunate" few and found they may not be so lucky after all. In fact, they found people who get more than eight hours of sleep have greater health risk compared to those who sleep together less than seven hours. What's more, sleep-aholics-those who manage to get 10 hours a night-stand a 30 percent higher chance of dying compared to the seven-hour crowd.
The wide-ranging global study involved(涉及) more than three million people who self-reported on their sleep habits and came to an eye-opening conclusion: If you tend to sleep a lot, you may want to buy an alarm clock. As with all things in life, sleep is best taken in moderation(适度).
You may be thinking: What if I only sleep in on Saturday and Sunday, am I still at risk? The answer is yes, according to a 2019 study published in Current Biology. Researchers discovered that even if a person sleeps more than seven hours on the weekends but still sleeps less than that on weeknights, they are at risk of gaining weight and developing sensitivity to insulin, which controls the level of sugar in blood.
For the study, 36 participants were divided into three groups that each had a different sleep schedule: nine hours every night, five hours every night, and five hours from Monday to Friday and sleeping much on weekends. People who get too much sleep tend to feel tired and lack energy. Also, both sleep-deprived(睡眠不足的) groups consume more food and gain weight.
Field Trip Day
On Friday, May 16, our class will take a field trip to North Park Zoo. The zoo has lions, elephants, and other interesting animals. Many of the animals we have been studying will be there for us to closely examine.
Our class will be divided into six teams. Each team will have five students and one leader. The leaders are listed in the table.
Team 1 | Miss Banker |
Team 2 | Mrs. Lopez |
Team 3 | Mr. Harper |
Team 4 | Miss Abel |
Team 5 | Mr. Soto |
Team 6 | Mrs. Thomas |
What You Need to Know
The cost is $1.00 for students to enter the zoo. We will leave the school at 9:00 a.m. and return at 2:30 p.m.
On the morning of the trip, the students will be divided into teams. One student from each team will receive a camera. The cameraman will take pictures of the team, the animals, and other fun sights at the zoo.
All members should wear blue shirts. Be sure to wear comfortable shoes because we will be walking all day. Please bring a bag lunch and a drink. We will have a picnic at the park inside the zoo. Bring a healthy snack, such as a piece of fruit and a drink, for later in the day.
When we are at the zoo, always remain with your team. Do not leave the team without asking permission from the team leader.
Feeding the Animals
The ONLY animals that students are allowed to feed are those in the children's Zoo. Special food can be bought at the zoo for 25 cents and given to these animals. Do not feed your lunch to them. It is not food for the animals.
