Are you really mad in the mornings? Do you wake up every day feeling tired, 1 or upset? If so, a 2 alarm clock could be suitable for you.
The clock SleepSmart is so 3 that it waits for you to be ready to 4 before waking you up. Its makers say it should make sure you wake up feeling refreshed (充满活力的) every 5.
During your sleep, you mainly pass through the sleep cycle(睡眠周期)—Non-REM Sleep (including Stage 1 and 2: Light sleep, Stage 3 and 4: 6 sleep) and rapid eye movement (REM) sleep—that repeats almost every 90 minutes. The points at which you wake can decide how you 7 later, and may even have a greater impact(影响) than how long you have 8. If you are woken up during light sleep, you are more likely to wake up full of energy and interest.
The clock was invented by a group of 9 at Brown University. "Most of our
classmates wake up 10 every day, and we want to do something about that," one of the inventors said.
