According to
"Synthesis and secretion of melatonin is dramatically affected by light exposure to the eyes. The fundamental pattern observed is that serum concentrations of melatonin are low during the daylight hours, and increase to a peak during the dark. "
"The duration of melatonin secretion each day is directly proportional to the length of the night."
This differs from plants in which even brief light exposure resets the clock.
Are there other sources for this type of information about sleep?Statistics: Posted by Nostradamus — 24 Mar 2010, 04:37
