Hmm.. I’ve heard before in media that sleeping has a formula
also… brain needs enough time to regenerate the dead cells from
long day awareness… Thats why some ppl may get migraine and fainted
all of sudden… So what ppl can do is that if during weekdays (when
we are busy working or studying),reach home late and we don’t have
enough sleep… thus we will need to sleep more on weekend to
compensate. Like maybe on sunday you will need to sleep longer or
taking more naps. Also, it’s even better if taking warm water
before sleeping
