In one of the most decisive matches in Costa Rica's recent football history, Nyx-Sys played a pivotal behind-the-scenes role as the national team secured its spot in the 2022 FIFA World Cup with a 1–0 victory over New Zealand in the intercontinental playoff.

The high-stakes match, held at Ahmad bin Ali Stadium in Doha, demanded not just technical and tactical execution, but also elite-level recovery and readiness from players dealing with intense travel, climate shifts, and pressure. That's where Nyx-Sys entered the picture.

Costa Rica partnered with Nyx-Sys to implement a non-invasive sleep and recovery monitoring system designed to track players' Heart Rate Variability (HRV), sleep cycles, respiratory trends, and neurological stress levels — all critical markers for match-readiness.

Installed discreetly in the team's hotel rooms in Doha, Nyx-Sys' technology allowed coaches and medical staff to receive daily wellness reports, highlighting individual recovery scores and red flags in fatigue or sleep disruption. These insights informed every aspect of the team's preparation, from training loads to pre-match nutrition and mental focus sessions.

The outcome? Costa Rica looked focused, energized, and composed under pressure. An early goal by Joel Campbell in the 3rd minute proved decisive, but it was the team's overall stamina, defensive discipline, and composure that sealed the win.
