How Biological Rhythms Affect Your Sleep

Biological Rhythms And Your Sleep

Your body is the result of millions of years of adaptation to the forces of nature. These natural forces are the movement of the planets, sun, moon and the stars. We witness these forces as the cycles of the ages, the seasons, tides, the days and the nights as well as the varied climates and weather patterns around the globe.

In actual fact there is a field of science called chronobiology. This is the field of biology that examines cyclic phenomenon in living organisms and their adaptation to solar and lunar related rhythms. “Chrono” pertains to time and “biology” pertains to the study or science of life. These cycles are known as biological rhythms. The most important biological rhythm is the circadian rhythm, a roughly 24 hour-cycle of the earth around the sun. Many aspects of not only human but all animal behaviour and physiology show circadian rhythmicity, including sleep, physical activity, alertness, hormone levels, body temperature, immune function, and digestive activity.

Some other important cycles are:
