long have science proven that light affects human bodily functions, such as our biological clock and hormonal release. pineal gland reacts to the signals sent by the ubiquitously spread photoreceptors in our body, regulating sleep cycle as well as the pituitary, the master control of our hormonal system. okay, before i started to sound too scientific and living the nerd stereotype my sister branded me with, i'll get to the question that has been bugging my mind for the past few days. how come our mood is affected by sunlight as well? is it hormonal? is there any physiological background or is it purely psychological? because i just noticed i am much happier and more enthusiastic at work when the sun in shining brightly outside the surgery window (although i can't really feel the warmth of it on my skin. sobs). i felt good yesterday morning (note: it was sunny), then in crappy mood for the whole arvo (note: it was cloudy) and the pattern followed this morning, when clouds hung low ready to pour down their contents, i felt sluggish and slow and sleepy. can anyone tell me why sunshine is such a mood lifter?
p.s. missing those times in the pic, where we were young and carefree :p and the sun was shining so brightly! i even miss the heat :(
