①You may think the best way to solve a difficult problem is to keep working on it, even overnight. But the truth is just the opposite: Your best chance to get to the bottom of a problem is actually to sleep on it.
②A team of researchers at North western University, US, did a study and found that sleeping is useful in both strengthening (强化) and re-organizing (重组) memory. This can help you solve problems.
③The researchers did an experiment with 57 students. They asked them to solve 42 difficult puzzles (谜题) on the first day. The students worked on each puzzle while listening to different music. The research encouraged students to remember the music they heard while solving the puzzles. By the end, there were six puzzles that the students still hadn’t solved. The students then went back home to sleep. They were given special sleep-monitoring (睡眠监测) and music devices (设备). The devices played music connected with the unsolved puzzles while the students were in the slow﹣wave sleep period. This period is when people are likely to dream and re-organize their memories.
④The next morning, the students tried the unsolved puzzles again. Researchers found they were 55% more likely to solve them. The music activated the memories about the puzzles while they were sleeping. It allowed them to “work” on the puzzles in their sleep.
⑤Earlier studies of both people and animals have shown that sleep can not only strengthen memory, but also help us organize information in our brains. This study seems to support that understanding.
⑥So the next time you face a difficult problem, sleep on it. Then play some music to help yourself think of the problem.
