What are polar day and polar night? Well, imagine you arrive in the small town in Northern Norway. The first thing you notice in your hotel room is thick black curtains. From the end of May to the end of July is like one endless day. Locals might be used to this extreme lifestyle but for visitors, it can be quite disorienting. Like having jet lag that just won’t go away.

During endless summer days, you don't have to adhere to your usual daily routine. It's always light, and you need to accept this. Wake up at 2 a.m? Great, go for a jog! If you want to sleep after lunch, go to bed and don't worry about it. Thanks to the endless sun, you're charged with energy, so all the people here are happy and active. They take advantage of these eternal days because when winter comes, so do the endless nights… So why does this happen?
