Most of us use alarm clocks to wake up at the right time for school or work. We look at our watches to know the right time for the bus or train. However, there is also a right time to eat, sleep, exercise, and take medicine. We can't look at a clock for the right time for these activities. We must listen to the clock inside our bodies—the biological(生物的) clock.
Barbara woke up at 6:00 a. m. She ran about five miles before she went to work. Then her legs and back started to hurt. She did some exercise before she ran. But her legs and back still hurt. She ran slower, but the pain didn't stop. Barbara talked to her doctor. The doctor said, "Try to exercise later in the day. That is the time when your body is at the right temperature for exercise after work." She did as the doctor said and her legs and back didn't hurt any more.
Today, doctors are learning more about chronobiology—the study of biological clocks. They are learning about the importance of time for our bodies. For example, it is best for people to go to sleep on time every night and to eat only when they're hungry. Also, doctors found that some illnesses, such as heart problems, happen most often in the morning. This information tells them that the best time to take heart medicine may be at night. When patients take heart medicine at night, they may stop a heart problem in the morning.
Many doctors believe chronobiology can help us live healthier lives. It may be the right time to listen to these doctors!
