After several years of minimal sleep and excessive physical demands, my body had to pay. I had a big time hormonal discrepancies ... my gynecologist called it "hormonal crisis". She blamed my night shift schedule for breaking my circadian rhythm. My hormones malfunctioned caused not only by sleep deprivation but also by stress and poor diet. That is another story I can go through later on. Anyways, now I require a lot more than two hours of sleep and that is my body's call, not my mental judgment. I am gifted in a way that I can do "power naps". I can program myself to sleep just like that and wake up feeling refreshed.
So what is wrong with me??? Maybe as my gynecologist claimed ... my circadian rhythm was and is out of wack. C I R CA D I A N RHYTHM is also known as the biological clock. A cycle that lasts 24 hours is called circadian. Some physiological functions that are circadian include body temperature and certain hormone secretions. Humans have a natural cycle of approximately the length of one day. Small structures in the brain called suprachiasmatic nuclei (SCN) coordinate circadian rhythms. The SCN is very sensitive to the presence or absence of light. This may explain why daytime sleep has been found to be less restful than nighttime sleep.
