Biorhythms...The Rhythms Of Life
What are biologic rhythms? In essence, they're the rhythms of life.
All forms of life on earth, including our bodies, respond
rhythmically to the regular cycles of the sun, moon, and seasons.
For example, as night turns into day, vital body functions, including
heart rate and blood pressure, speed up in anticipation of increased
physical activity. These and other predictable fluctuations in body
function, taking place during specific time cycles, are our biologic
rhythms. They are regulated by "biologic clock" mechanisms located in
the brain.
Although biologic rhythms can be "reprogrammed" by environmental
influences (such as when a person regularly works the night shift and
sleeps during the day), they are genetically "hard-wired" into our
cells, tissues, and organs.
Medical chronobiologists have found that biologic rhythms can affect
the severity of disease symptoms, diagnostic test results - even the
body's response to drug therapy. Now these investigators are working
to discover how the rhythms of life can be used to improve the
practice of medicine - and your health.
These time-related medical observations, and others still
in the exciting process of discovery, are rooted in chronobiology
(chronos - time; bios - life; logos - science), the study of
biologic rhythms.
