At the beginning of this century medical scientists made a surprising discovery: that we are built not just of flesh and blood but also of time. They were able to demonstrate that we all have an internal “body clock” which regulates the rise and fall of our body energies.
Scientists have identified the following three biorhythmic cycles: physical, emotional and intellectual. Each cycle lasts approximately 28 days and each is divided into a high energy period and a low energy period of equal length.
During the low energy period we are less resistant to illness and tire more easily. The low period puts energy into our “batteries” for the next high period. During the high energy period of a physical biorhythm we are more resistant to illness, better coordinated and more energetic.
The “critical” or weakest time is the time of changeover from the high energy period to the low energy period, or vice versa. On the critical day of a physical biorhythm, there is a greater chance of accident and illness.
