In 1751, Swedish botanist Carolus Linnaeus came up with the novel idea of using flowers as clocks. Morning glories open their trumpetlike petals around 10 a.m., water lilies at 11 and so on through evening primroses and moonflowers. A full array of these blossoms, planted in a circle, could indicate the time. It was a whimsical notion. But some 250 years later, scientists are seriously interested in the timekeeping mechanisms of nature.
From cockroaches to humans, these internal clocks influence far more than our sleep. Heart attacks are more common in the morning. Women tend to go to labor in the evening. Severe breathing difficulties prevail at night. Even our responses to medicines may depend on when we take them.
Nature has devised internal clocks for a simple reason: they aid survival. "The early bird really does get the work," -- thanks to a silent wake-up call before dawn. A mimosa plant spreads its fernlike leaves during the day to crete the maximum surface area for photosynthesis, then folds them up at night to reduce water-vapor loss. It's not a mere response to light.
In humans, the master clock in the brain orchestrate a series of biological events that unfolds in sequence. In the hours before breakfast, the body releases digestive enzymes gradually to be ready for the first meal. Temperature and blood pressure rise in preparation for the day's demands. This helps explain the morning increase in the heart attacks. Cells reproduce at set times. Hormones rise and fall -- many of them according to a predetermined schedule.
