Just repeating all the other comments from people living in the Nordics: it's a hassle now during summer to sleep anywhere you don't have good blinds to get near-complete darkness.
Not only that but you feel that your body doesn't relax at night time, here in Stockholm right now there is sunlight up to 21-something, never getting completely dark after that until the sun is up again around 03.00, my body is still fully awake with energy until way past 23.00 when usually during winters I'll feel tired by 18.00 as it is dark since around 14.30-15.00.
I'm not Swedish but every Swede I know go through these cycles around the year, living here for 6 years hasn't changed much in terms of adaptation except that I just know that's how it works.
