Adele has revealed she suffers from seasonal affective disorder, also known as SAD, which makes it difficult for her to live in the UK.
The singer has lived in Los Angeles since 2016 and last year bought a mansion there said to be worth $58m (£47m).
She told The Hollywood Reporter she loves living in LA - in no small part thanks to the weather.
"I get really bad seasonal depression, so the weather is good for me here.
"It is strange sometimes, because I'm very British."
SAD is a recurrent form of depression that comes on in winter and is marked by extreme tiredness, withdrawing from social activity, enduring low mood and increased appetite.
Adele also said she liked living in LA because she gets "left alone".
"For anyone that has never been to LA, you assume it would be the opposite. But there are so many famous people here that they don't waste their time."
But her love for her new life doesn't mean she's not homesick. Discussing her song Hometown Glory, she said it made her "very emotional".
"I really miss London, but I miss the London from before all of this happened in my life."
She said she remembered writing the song "like it was yesterday".
"I wrote it the day after I went to my first ever protest. In London, the UK, we were annoyed at Tony Blair because he was going to war with Iraq.
"It was like a million-people turnout in London, and we're marching, and I was 16, and me and my friend Olivia went. We made our placard, and it felt so powerful."
Last month, Adele "confirmed" she had married her sports agent boyfriend Rich Paul, reportedly sharing the news with the crowd at an Alan Carr show.
She told The Hollywood Reporter: "Rich and I have always known everything about each other since the day we got together."
Reading about his late mother in his memoir was "very emotional", she said, as she never got to meet her.
Adele also shared one thing he does that drives her "insane" - listening to her music.
"It's funny because in my car with my driver, he knows if my song comes on, he has to turn the radio, just turn it off (laughs). I don't like it at all."
