This time of year is called "White Nights" because it barely gets dark. When I was in Mirny, the sun set at about 11:25 p.m. and rose before 3:30 a.m, but it never got completely dark.
As a traveler, it was fascinating and disorienting — but even those who permanently live in Mirny struggle with the long hours of daylight. An Alrosa employee who moved to Mirny from another town in Yakutia told me she can sometimes only sleep three to four hours a night during this period.
"Locals that were born here take it easier but also use blackout curtains and eye masks," she said. "That's the main life hack — make it as dark as possible when you go to sleep."
