Umeå is especially dark in the winter. Located in northern Sweden 300 miles north of Stockholm, it's only sunlit for about five hours a day this time of year, according to the English-language Swedish newspaper The Local. Come mid-December, there will be just about four hours of daylight. Usually snow on the ground reflects streetlights and makes the city feel brighter, but there hasn't been enough snow this year, making things even darker than usual, The Local explains. "Even though it snowed today, the sun had set by 2pm. People need to get their vitamin D somehow!" Göran Ernstson, CEO of Umeå Energi, was quoted saying.
