I am not trying to deny some science documentary being reproduced as melatonin etc. Many science factors are as good as or even smaller than our ethics and scriptures. Science is not a de facto authority. Now let me ask: people who never saw TVs or one with cell phones, not even radios, who were healthy could not sleep. Many lost their sleep even as we read our scriptures and sanga verses. So even after seeing cell phones, till 2 PM at this age I am able to sleep; many do sleep; but sleeplessness is mainly due to sickness and pain. And worries. Kalanginaan Ilankai vendan enbadhu kamban kootru. People who spend their time by good body and mental exhaustion must sleep even if 10/ 1000 watts bulbs are lighted. It is psychological reversions. Melonin etc are some reasons attributed. No one verified the truth of science individually or questioned-How do you know; even if explained, many do not have the deptjh to understand as they are not conscious of them. It is called HERDS' INSTINCT( PSYCHOLOGY). Because all say they do believe. And ALL is defvined wrt the groups they want to choose according to their Guina vibhaga:. K R IRS 251024
