Do you wake up every day feeling too tired, or even upset? If so, then a new alarm clock could be just for you.
The clock, called SleepSmart, measures your sleep cycle, and waits【C1】_____you to be in your lightest phase of sleep【C2】__rousing you. Its makers say that should【C3】_____you wake up feeling refreshed every morning.
As you sleep you pass【C4】_____a sequence of sleep states—light sleep, deep sleep and REM (rapid eye movement) sleep—that【C5】__approximately every 90 minutes. The point in that cycle at which you wake can 【C6】__how you feel later, and may【C7】__have a greater impact than how much or little you have slept. Being roused during a light phase【C8】_____ you are more likely to wake up energetic.
SleepSmart【C9】_____the distinct pattern of brain waves【C10】__during each phase of sleep, via a headband equipped【C11】__electrodes and a microprocessor. This measures the electrical activity of the wearer’s brain, in much the 【C12】__way as some machines used for medical and research【C13】__, and communicates wirelessly with a clock unit near the bed. You【C14】__the clock with the latest time at which you want to be【C15】__, and it【C16】_____ duly wakes you during the last light sleep phase before that.
The【C17】_____was invented by a group of students at Brown University in Rhode Island【C18】__a friend complained of waking up tired and performing poorly on a test. “【C19】__sleep-deprived people ourselves, we started thinking of【C20】_____to do about it,” says Eric Shashoua, a recent college graduate and now chief executive officer of Axon Sleep Research Laboratories, a company created by the students to develop their idea.
When it comes to eating smart for your heart, stop thinking about short-term fixes and simplify life with a straightforward approach that will serve you well for years to come.
Smart eating goes beyond analyzing every bite you lift【C1】_____your mouth. “In the past we used to believe that【C2】__amounts of individual nutrients were the【C3】__to good health,” says Linda Van Horn, chair of the American Heart Association’s Nutrition Committee. “But now we have a【C4】__understanding of healthy eating and the kinds of food necessary to【C5】__not only heart disease but disease【C6】_____general,” she adds.
Scientists now【C7】_____on the broader picture of the balance of food eaten【C8】__several days or a week 【C9】__than on the number of milligrams of this or that【C10】__t each meal. Fruits, vegetables and whole grains, for example, provide nutrients and plant-based compounds【C11】__for good health. “The more we learn, the more【C12】__we are by the wealth of essential substances they【C13】__,” Van Horn continues, “and how they【C14】_____ with each other to keep us healthy.”
You’ll automatically be【C15】_____the right heart-healthy track if vegetables, fruits and whole grains make 【C16】__three quarters of the food on your dinner plate.【C17】_____in the remaining one quarter with lean meat or chicken, fish or eggs.
The foods you choose to eat as well as those you choose to【C18】_____clearly contribute to your well-being. Without a【C19】__, each of the small decisions you make in this realm can make a big【C20】_____on your health in the years to come.
