Article: Homework can put you in a badmood , and that might actually be a good thing. Researchers from the University of Plymouth in England doubted whether mood might affect the way kids learn. To find out the answer, they did two experiments with children. The first experiment tested 30 kids. Someshapes were hidden inside a different, larger picture. The kids had to find the small shapes while sitting in a room with either cheerful or sad music playing in the background. To test their mood, the scientists asked the kids to point to one of five faces, from happy to sad. Children who listened to cheerful music tended to point to the smiley faces while the others pointed to the unhappy ones. The researchers found that sad kids took at least a second less to find the small shapes. They also found an average of three or four more shapes. In the second experiment, 61 children watched one of two scenes from a film. One scene was happy, and the other was sad. Just like in the first experiment, kids who saw the sad scene acted better compared to the others. The researchers guessed that feeling down makes people more likely to focus on a problem or difficult situation. Not all scientists agree with them, however. Other studies argued that maybe, that cheerful music in the first experiment distracted kids from finding shapes. While scientists work on finding out the answers, it still might be wise to choose when to do your tasks according to your mood. After eating a delicious ice cream, for example, write an essay.

New input: Article: Let's face it -- you're going to get a lot of well-intentioned advice from friends, parents and grandparents about your sleep. Some of this advice is going to be just wrong. Myth 1: Sleeping late on the weekends will make up for lost sleep during the week. Fact: Getting less than the amount of sleep that you need night after night accumulates over time and starts to create a "sleep debt". And like all debts, eventually you need to pay the price. The problem with waiting until the weekend to meet sleep needs is that in the meantime, you are paying the price of being less alert, feeling more moody, thinking slower and having less stimulation. Myth 2: A boring teacher (or warm room, full stomach, etc.) can put teens to sleep. Fact: If you are getting enough sleep on a regular basis, there is no teacher, math book or reading assignment in the world boring enough to make you fall asleep in class. There are basically two things that make people sleepy -- not getting enough sleep and not getting good quality sleep. The environment kids are in, including the room temperature, light level and entertainment value, may unmask underlying sleepiness, but the environment does not cause it! So if you are dozing off in class, don't blame it on bad teaching. Myth 3: Teenagers can pull an all-nighter to study and still be ready for the big test in the morning. Fact: Teenagers are much better off studying less and getting a good night's sleep. Research clearly shows that the ability to concentrate and learn new information, as well as to work efficiently, declines sharply after being awake for 15-16 hours, and continues to bottom out the longer you stay up. Plus, if the big test is at 8:00 am, the problem gets even worse. That's because morning time typically represents a low energy point in the body's normal 24-hour circadian rhythm, especially in teenagers.
