What Is the Heart Rate Challenge in Love Island Season 7
Love Island season 7 introduced a heart rate challenge format where contestants wore wrist-based biometric sensors during key tasks to capture real-time pulse data. Producers used the data to create on-screen heart rate overlays and to determine which couples stayed together during coupling ceremonies. The challenge was developed by ITV Studios in collaboration with a wearable technology provider and a data analytics partner to turn physiological signals into a broadcast feature. The format was first piloted in earlier Love Island seasons and expanded in season 7 with higher sensor accuracy and more visible on-screen metrics ITV Press Centre.
The heart rate challenge was integrated into the main show schedule, with episodes airing five nights a week on ITV1 and streaming on ITV Hub. Production company Lift Entertainment oversaw the challenge design, while ITV Studios handled distribution and brand partnerships. The format was supported by a dedicated data team that monitored heart rate spikes during recoupling scenes to generate highlight reels for social media. The challenge was also used to test audience retention, with ITV reporting higher completion rates for episodes featuring the biometric segments Forbes.
How Biometric TV Formats Drive Audience Engagement and Ad Revenue

ITV reported that episodes featuring biometric segments generated higher social media conversation volume and increased second-screen activity during ad slots. Advertisers paid premium rates for placements tied to heart rate spikes because the data provided a measurable signal of viewer attention. The format also enabled dynamic ad insertion on ITV Hub, where ads were served based on the intensity of the on-screen heart rate data Forbes.
The heart rate challenge format is part of a broader trend in which broadcasters use wearable data to create interactive storytelling and targeted advertising. ITV partnered with data firms to analyze heart rate trends across episodes and to share anonymized insights with advertisers through its ad sales platform. The data was used to build audience segments based on emotional response patterns, which were then matched with relevant brand campaigns. The format also influenced commissioning decisions for future seasons, with ITV greenlighting additional biometric challenges based on season 7 performance ITV Press Centre.
