Circadian rhythm: Is the normal (about 24 hours) rhythm of the brain that is controlled by the night/day cycle. During part of each 90 minute sleep cycle we have about 10 minutes of rem or active sleep when the autonomic nervous system (ans)(automatic) becomes active. Your ANS activity is exaggerated and unbalanced and the commonest cause is poor diet, especially all that sugar and sweeteners if it applies to you.
