Lyrically, Bastille's Wild World album focuses on the human condition. Frontman Dan Smith tackles both the effect the viewing of the horrors of the world through the media has on us and our innate need for relationships.
"Conceptually, the song that really started tying it together was 'Warmth'," he told DIY magazine "That was the track that articulated, for the first time, how overwhelming it can seem to be watching or reading the news and it seeming so mad and confusing. It's about figuring out ways to react against that, and sometimes that is just running to the person that you love because they're the perfect distraction in that situation."
Dan Smith told NME about the song's meaning: "It's about that feeling of panic and of helplessness and how that's now part of everyday life. As a human being, how do you react to that? Do you try to engage with it? Do you bury your head in the sand? Do you go get drunk? And, in the context of all of that, I think the things that make life generally awesome are other people and our relationships and humor."
Bastille released a live video of them performing the song at Capitol Studios in L.A. Said Dan Smith: "We wanted to strip 'Warmth' back to present it in a way that shows off the emotion of the song, and we were lucky enough to record this version at the legendary Capitol Studios with a brilliant strings section."
