During the production of the fifth album, Lovato commented: "I've already started recording for my new album, and I have plans to record during the tour. The sound just evolves into everything that I've been and everything that I want to become." She further stated, "I've never been so sure of myself as an artist when it comes down to confidence, but not only personal things, but exactly what I want my sound to be and what I know I'm capable of and this album will give me the opportunity to show people what I can really do." In May 2015, Billboard revealed Lovato was in the process of starting an "artist-centric" new record label, Safehouse Records, of which she will be co-owner. The label will be a partnership between her, Nick Jonas, and Lovato's manager Phil McIntyre, and will form part of a new collaborative arrangement with record label Island. It has been confirmed that Lovato's upcoming fifth studio album will be released through the new venture deal. This will be Lovato's second multi-label venture of her career; she was formerly part of Jonas Records, a UMG/Hollywood/Jonas Brothers partnership, which is now defunct.
On June 6, 2015, while headlining at the DigiFest NYC, she revealed to the audiences: "It’s going to be a real exciting summer for my fans, I cannot wait for you guys to hear some new music." The song was recorded in Max Martin's production studios Wolf Cousins, formed in Stockholm in 2013. Lovato released a video on her official YouTube account on October 10, 2015 explaining the meaning behind "Cool for the Summer".
The song was written and produced by Max Martin, co-written by Lovato, Ali Payami, Alexander Erik Kronlund, Savan Kotecha. Tharadjyne Orisma from United Press International noted that the song "makes some pretty racy suggestions" and described the lyrics as "saucy".
After the song's leak, Yasmeen Gharnit from Nylon called the song "a blatantly summer song" with "boisterous, cinematic instrumentals and synth beat" distract from "some straight-out-of-your-middle-school-diary lyrics". Following its official release, Jason Lipshutz of Billboard gave the song four and a half out of five stars, calling it Lovato's 'most self-assured statement to date'. Mike Wass of Idolator rated the song an average of 7.5 out of 10.
The following includes some of Demi Lovato's live performances of "Cool for the Summer".
The music video released on July 23, 2015 on Vevo. The video was directed by Hannah Lux Davis and shot in Los Angeles, California from June 29–30, 2015.
Christina Garibaldi of MTV deemed the video "seductive, sassy and smokin' hot" and noted the video marked "a new chapter of her career, as she exudes a confidence and sexiness that we haven't seen before." Bianca Gracie of Idolator and Lewis Corner of Digital Spy both thought the video is Lovato's "steamiest". Hayden Manders of Nylon wrote that the video "doesn't disappoint, but it somewhat misses the mark" explaining "it's odd that a video for a song about same-sex experimentation features none. You'd have to listen to the lyrics to understand the underlying message of the song because the video shies away from it." New York's Dee lockett called it "the most sexually liberated video Demi's ever done to go along with its empowering — and also somewhat queer-baiting — message."
