I don't know. Fine I guess. The lack of light or the lack of darkness affects people differently but people who have lived here longer have gotten used to it better. The bright time is never the same because the day of course constantly either gets few minutes shorter or longer every day depending if your going towards summer or winter so you get used to it. And of course during the summer, if brighter nights (the sun being near the horizon in the night but still visible) are keeping you awake, there's always dark curtains. I have thick black curtains in my bedroom.

I always get more things done in the spring and summer as it's brighter as I'm such a sunlight oriented person. And I don't actually feel tired even if I sleep less. But in the fall and winter I feel like I could go and hibernate. Although I take extra vitamin D and have lights here at my home, for the plants mostly, the darkness outside, lasting 19 hours is really depressing. But fortunately after this day, the day is getting longer, minute by minute.
