Lyrics and composition The song features Maxi Jazz rapping from the point of view of an insomniac while he struggles to sleep ("I toss and I turn without cease, like a curse, open my eyes and rise like yeast/At least a couple of weeks since I last slept, kept takin' sleepers, but now I keep myself pepped"). The subject is resonant with fans of dance music, as stimulant use is common in club/rave culture, and insomnia is a common side effect - in a 2020 interview, Maxi Jazz acknowledged how it struck a chord with clubbers: "Suddenly the song was being played to crowds who had arguably taken 50 quid’s worth of high-powered drugs and weren’t thinking of getting much sleep for days... If I had a quid for every time someone’s come up going, 'I can’t get no sleep', I’d be living on the space station". The insomniac is also rather destitute ("Make my way to the refrigerator/One dry potato inside, no lie, not even bread, jam, when the light above my head went bam..."). According to Maxi, he spent 20 minutes writing the lyrics after being given the song's title by Rollo Armstrong, before finishing them in the studio the following evening and laying the vocal down in about 25 minutes. Although he was not an insomniac, Maxi drew on personal experience for the lyrics: he had recently suffered a painful dental abscess which had kept him awake at night. Lines about the light going out and picking up a pen in darkness were based on the prepayment electricity meter in his home, which would cut out when credit ran out, forcing him to write by candlelight.

According to Sister Bliss, the track's music was written in bandmate Rollo's recording studio, located in a garden shed: she came up with the song's title as she was unable to sleep, describing the experience of working in the studio during the day and DJing at night as being "like having permanent jetlag". She has stated that the song's reggae-inflected bassline was influenced by Lionrock, whilst placing the main keyboard riff towards the end of the song "was an idea we got from Underworld’s way of building tension: just waiting, waiting, waiting then – bang!". Sister Bliss wrote the riff after Rollo asked her to "do big strings", borrowing the idea of shifting from a major chord to a minor chord from Donna Summer's "I Feel Love".

Release The album version is nearly nine minutes long and contains some lyrics not able to be broadcast on the radio edit due to their explicit content. Maxi Jazz changed the opening line from "I only smoke weed when I need to" to "Deep in the bosom of the gentle night" due to pressure from MTV. It also contains some bells chiming at the start of the song (sampled from a BBC Sound Archive disc) not generally known by the club-going public as many people know the Monster Mix or the Monster Mix Radio Edit. The beginning of the Moody Mix of the song also features a sample from Biosphere's "Novelty Waves" (1994). The version present on the album Reverence is an edit that combines the Moody Mix and the Monster Mix, meaning the sample is also present on the album version. The Monster Mix was the mix featured on Faithless' greatest hits album Forever Faithless, with the original edit being the work of Radio Victory's Bill Padley. This edit was picked up by BBC Radio 1 upon release in 1995 and became a small UK Top 40 hit, with the Cheeky label's recording being licensed through Champion Records at the time. After the song gained popularity in continental Europe, Pete Tong campaigned for a re-release: Cheeky/Champion chose to hold back the re-issue so it arrived in shops on the same day as the Spice Girls' "Say You'll Be There", so it would be placed in racks alongside it. The song charted at number 3 in the UK, appearing two places below the aforementioned Spice Girls single, while also topping the UK Dance charts. The song also went on to top the US Hot Dance Club Play chart. The Moody Mix featured on some of the singles was also on the Reverence / Irreverence release.

Critical reception Justin Chadwick from Albumism described the song as a "frenetic yet melodic ode to late night restlessness and sleep-deprived reveries", adding it as "phenomenal". Larry Flick from Billboard wrote, "This single serves as a fine peek into the project, giving listeners a taste of urgent dance rhythms, a complex and infectious pop melody, and vocals that are notches above the typical vamps heard on club-originated records." Complex said that Faithless' "Insomnia" "spoke to a number of ravers out there who lived for the night/weekend and, sadly, the drugs that kept them partying to the break of dawn (and beyond). Insomnia was and is real for the raver massive, and Faithless brought those vibes to song perfectly." Gerry Kiernan commented on the song in the 2010 book 1001 Songs You Must Hear Before You Die, "Unleashed in an era of uplifting "handbag" house", "Insomnia" crept with nocturnal stealth through rave culture into suburban bedrooms. As its title suggested, this climatic, hands-in-the-air dance anthem was not one to put on before bedtime." Tim Jeffery from Music Weeks RM Dance Update rated it four out of five, writing, "Following very much in the style of its predecessor with all the Rollo production hallmarks including the piercing organ and synth riffs and a bouncy bassline. As with the debut, there's also the half speed section in the middle to incorporate the rap and vocals which aren't as instant as 'Salva Mea' but grow on you. With the formula now established, this one may fare better commercially." Ben Turner from Muzik noted that "it has soul, grace, emotion and a distinctly dark, melancholic side. Happy house has never been challenged in this way."

In 2020, Mixmag featured it in their "The Biggest Drops in Dance Music", writing, "Maxi Jazz's spoken words about struggling to kip - alongside a heartbeat build-up - are deeply ingrained in worldwide consciousness, as are the piercing, relentless synth stabs that burst into the tune a few minutes in. You'll do well to get some shut-eye after turning this one up loud. Anthem, mate, absolute anthem."

In March 2026, American singer-songwriter Bebe Rexha interpolated the melody of "Insomnia" in her single "New Religion", which is credited as a duet between Rexha and Faithless.
