Choosing the right time to sleep, the right moment to make decisions, the best hour to eat — and even go into the hospital — could be your key to perfect health.
Centuries after man discovered the rhythms of the planets and the cycles of crops, scientists have learned that we too live by precise rhythms that govern the ebb and flow of everything from our basic bodily functions to mental skills. Man is a prisoner of time.
But it's not just the experts who are switching on the way of our bodies work. An increasing number of people study the state of their bio-rhythms before making their daily plans. Prince Charles consults a chart that tells him when he will be at his peak on a physical, emotional, and intellectual level. Boxer Frank Bruno is another who charts his bio-rhythms to plan for big fights.
Leading experts say daily rhythms influence every aspect of human biology. Sleep, blood pressure, hormone levels, and heartbeat all follow their own clocks, which may bear only slight relation to our man-made 24-hour cycle.
Research shows that in laboratory experiments when social signals and, most crucially, light indicators such as dawn are taken away, people lose touch with the 24-hour clock, and sleeping patterns change. Temperature and heartbeat cycles lengthen and settle into "days" lasting about 25 hours.
In the real world, light and dark keep adjusting clocks to the 24-hour days. But the best indicator of performance is body temperature. As it falls from a 10 p.m. high at 37.2 degrees Celsius to a pre-dawn low of 36.1 degrees Celsius, mental functions fall too. This is a key reason why shift work can cause so many problems for workers and their organizations.
The most famous example is the nuclear accident at Three Mile Island in the U.S. The three operators in the control room worked alternating weeks of day, evening, and night shifts — a dangerous combination that never gave their bodies' natural rhythms a chance to settle down. Investigators believe this caused the workers to overlook a warning light and fail to close an open valve.
