ccording to many researchers, daylight plays a growing role in the human body and more precisely in homeostasis. How far it goes in so doing is still a mystery and scientifically speaking, seems to be at the verge of being identified.  Nevertheless  it   becomes more and more obvious that daylight by entering our eyes triggers a cascade of phenomenon that goes beyond what used to be expected from daylight  we tend to take for granted.


One of these phenomenon and not the least is hormone synthesis. Daylight participates in the synthesis of three human hormone considered capital in human balance. They are serotonin, melatonin and vitamin D, let alone reproductive hormone, ovulation and the sterols.

To get started, the  boost of serotonin is instrumental in our mood and affect. When getting low, serotonin affects  human being feelings, generating  depression and mood switching. We also  know that this lowering is associated with  some bipolar symptoms. Medicine faces this situation by lifting up our blood serotonin level.

Secondly, melatonin’s synthesis is triggered by darkness and sleep. Researchers believe that this rise at darkness and   daylight fall is associated with the so called circadian cycles. There also, the balance in wake and sleep time is monitored by melatonin.  Needless to say that a lot of biological hormone relate to melatonin  balance.

Finally, vitamin D, the gene proofreader is likewise instrumental in the regulation of many other hormone  in our throughout system.

Whatever their role and the organs they target, these  light induced-hormones while calling for more interest in this cosmic phenomenon, pave at the same time the way for further investigation. The coming years would witness the growing importance of light in life and as a result its implementation in daily and medical life.
