Few of us make money by losing sleep.But three graduate students at Brown University in Providence built a company around sleep deprivation (睡眠不足).
Jason Donahue, Ben Rubin and Eric Shashoua were working late nights in Brown's business and engineering schools.They began thinking about ways to sleep better.They discovered they weren't alone in burning the midnight oil.Around 20% of Americans get less than six hours of rest a night.
The friends imagined a smart alarm clock that could track how much time people spend in the most restorative (有回复作用的) stages of the sleep cycle: REM (rapid eye movement) and deep sleep.What would it cost to design such a thing? Five years of research, 20 employees, $14 million and a whole lot of doubting from investors and scientists.
Their company, Zeo, based in Newton, Mass, launched its product in June, 2009.The Zeo device uses a headband with tiny sensors (传感器) that scan your brain for signs of four sleep states- REM, light, deep and waking sleep.The smart alarm clock displays a graph of your sleep pattern and wakes you as you're not in REM sleep (which is when you're least groggy).In the morning you can upload the data to the company's Web site, and so track your sleep over time.Most of the feedback comes in the form of Zeo's ZQ score showing how well you've slept.
"Zeo allows people to unlock this black box of sleep," says Dave Dickinson, a health-care CEO.
Whether any of this actually improves sleep is up to the consumer, who will also need to make lifestyle changes like cutting out alcohol before bedtime or caffeine after 3 pm.
For now the company is selling Zeo online only.Dickinson also plans to spread it to countries such as Australia, where sleep deprivation approaches US levels.
【小题1】Who will support Zeo?
A.People full of imagination. | B.People suffering sleeping problems. |
C.People having access to the Internet. | D.People having bad lifestyles. |
A.To wake them up on time in the morning. |
B.To earn enough money for their study. |
C.To improve the quality of people's sleep. |
D.To enjoy their life while working at night. |
A.spent much time and money | B.were widely supported by scientists |
C.worked by themselves all the time | D.attracted many investors |
A.Zeo has a direct effect on users' lifestyles. |
B.It needs more personal efforts to make Zeo function better. |
C.A large quantity of Zeo devices have been sold in Australia. |
D.Consumers can go to the Zeo company to purchase Zeo in person. |
I have nothing to say about whether or not "A Day Without Immigrants" had a positive or negative effect on the question of how the federal government should deal with the huge population of undocumented illegal immigrants in this country. I'll leave that question to others.
Regardless of how you feel about the event, one conclusion is obvious. Using the theme of" A Day Without" as a way to focus national attention on a particular subject is a great idea, and could serve as a method for increasing public awareness about other issues that affect daily life in America. Here are my top three examples:
"A Day Without Speeding." How hard could this be? If all drivers would strictly obey every posted speed limit on highways, downtown, on neighborhood streets, and in parking lots for one 24-hour cycle, the benefits would be huge.
"A Day Without Losing Your Temper." A higher degree of difficulty here, and I know that from personal experience. When something goes wrong at home or on the job, there may be brief satisfaction in yelling or kicking the furniture, but erupting with anger usually doesn't do anything to solve the problem, and in many cases it makes the situation more unpleasant.
"A Day Without Having All The Answers." I would like to get a break from hearing anyone speak the phrase, "Here's what you're doing wrong." Right now the US is jampacked with citizens who believe they can point out the cause of every single problem in existence and then solve it on the spot. I believe they need to be quiet sometimes and use their ears instead of their voices.
I wonder how would average Americans react to such a collective pause? Would it be a day of angry protests, or joyful celebrations?
【小题1】The first paragraph suggests .
A.the writer is against A Day Without Immigrants |
B.immigrants are not equally treated by the US federal government |
C.the writer cares little about the problems of the country. |
D.some people move to America without the permission of the US government |
A."A Day Without Immigrants" |
B."A Day Without Having All The Answers" |
C."A Day Without Speeding" |
D."A Day Without Losing Your Temper" |
A.personal | B.satisfying | C.pointless | D.unpleasant |
A.he thinks the American are too proud |
B.he doesn't think what he is doing is wrong |
C.he wants others to keep quiet |
D.the writer is so tired that he needs a break |
Sleep is a basic necessity of life and it is as important to our health as air, food and water. When we sleep well, we wake up feeling energetic, alert and ready to face daily challenges. When we don’t every part of our lives can suffer.
A survey made by the 2002 National Sleep Foundation (NSF) in America found that 74 percent of American adults are experiencing a sleep problem a few nights a week or more and 39 percent get less than 7 hours of sleep each night and want to have a sleep during the day.
Getting enough continuous quality sleep influences how we feel and perform next day. Getting enough sleep refers to the amount of sleep you need not to feel tired next day. Although sleep experts generally recommend an average of 7-9 hours each night, some people can get along with less while others need as many as ten hours to feel energetic next day. Sleep requirements vary(变化)over the life cycle. Newborns and babies need a lot of sleep and have several periods of sleep throughout a 24-hour time period. Teenagers’ sleep patterns turn to a later sleep-wake cycle, but they still need around 9 hours of sleep. Throughout adulthood, even as we get older, we need 7-9 hours of sleep. Sleep patterns may change, but the need for sleep remains the same.
According to the 2002 poll. Over 80 percent of American adults believe that not getting enough sleep leads to poor performance at work, risk of injury, poor health and difficulty getting along with others. Often, people become easily annoyed due to lack of sleep. Recent research suggests that lack of sleep also leads to approximately 100,00 sleep-related traffic accidents each year and results in 1,500 deaths.
If you are having sleep problems, turn to a sleep diary published by the National Sleep Foundation. A sleep diary helps you examine some of your health and sleep habits so that you and your doctor can find some reasons for poor sleep. Establishing a regular bed and wake-up schedule may also help you sleep well. Besides, talking to your doctor or a sleep specialist is of great help. Most sleep disorders can be successfully treated once properly diagnosed(诊断).
