I know it's extremely hard for many, specially in tropical countries like Bangladesh, to imagine this situation. I have been asked soo many times these questions, "well, how do you know when to sleep, when to wake up? How do you know when to eat lunch?". True, in tropical countries, the whole habit runs around the sun, during lunch time you expect the sun to be the brightest, you expect to go to work in full day light and come back home when it's getting darker. But once your body clock gets rid of sun clock, you actually then get used to follow your wrist watch. I did'nt say it's piece of cake though ;)

Anyways, there is also another misconception. It is not necessarily pitch black during the "continuous nights". Sun rays actually bend into the atmosphere and give some sort of light, as in the picture. It's called 'night' coz the sun is below the horizon.


Oh, yes, if you dont see the sun for that long, it's freeeeezing cold. And yes, it also affects your mode.
