The track was first released on streaming service Tidal and added to contemporary hit radio playlists in Poland by Extensive Music and Magic Records on 17 February 2016.

The song's music video, directed by Olga Czyżykiewicz, depicts two classical elements: water and fire, and features multiple dance sequences performed by Margaret and her dancers in various types of sceneries.

Margaret promoted the single with live performances on television and at festivals in Poland and Sweden, and also included the song on the set list of her 2019 Gaja Hornby Tour and her 2023 MTV Unplugged concert special.

[3] Music critics described it as "Scandi-pop hybrid of Rihanna and Kesha," comparing it to David Guetta's single "Hey Mama" (2015).

[7] "Cool Me Down" was released to Polish contemporary hit radio on 17 February, and was made available to stream exclusively on Tidal in Poland the same day.

[12] The song and its three remixes were included on the reissue of Margaret's debut studio album Add the Blonde (2014) released on 2 December 2016.

[13] The "Special Limited Box" edition of Add the Blonde released on 23 December 2016 included a 7-inch vinyl of "Cool Me Down" with the album's third single "Heartbeat" as the A-side.

[14] In November 2015, Margaret with producers and songwriters Wrethov, Arash, and Uhlmann were in a recording studio working on a song.

However, the decision to select Polish entry for the contest in a national final was made last minute by new TVP chairman Jacek Kurski who took over in January 2016.

[16] On 16 February 2016, TVP confirmed that Margaret was one of the nine artists selected to participate in the final of Krajowe Eliminacje 2016 with "Cool Me Down".

Aderemi wrote that "lyrically the song is on point, whilst its parent sound pulses over an infectious diffraction of modern beats."

"[4] In a positive review, Idolator' Mike Wass commented that "the newcomer [Margaret] pulls off an Eva Simons-like miracle – remember "Silly Boy" – by beating Rihanna at her own game," concluding that "this ["Cool Me Down"] could work stateside.

Chalkley further explained that the song "exists at a pop-cultural tipping point and the ways in which Margaret's stomper succeeded and failed could affect the sound of the contest for years to come.

It peaked at number 36 in its sixth week,[29] and was certified gold by the Swedish Recording Industry Association (GLF) on 10 June 2016.

[41] She promoted the single extensively in Poland throughout 2016 with numerous live performances, including on Dancing with the Stars: Taniec z gwiazdami,[42] at Eska Music Awards,[43] and at Polsat SuperHit Festival.

The song draws many similarities to "Cool Me Down", which prompted some fans to make plagiarism accusations against Brening on social media.

[54] In 2018, Adriana Kalska performed it on season 10 of Twoja twarz brzmi znajomo (Polish version of Your Face Sounds Familiar) recreating its music video.
