World Cup Sleep Loss: The Emotional Cost of One More Match

July 3, 2026 Sleep TrackerOuraSports Recovery$349+FIFA World Cup Opening I used to be the guy who turned the TV off at 90 minutes. Then my team went to extra time, the chat filled with “one more match” texts, and five weeks later I missed three deadlines, snapped at my partner over burnt toast, and scored a 47 on my Oura Ring — my lowest readiness score ever. If you are deep in the FIFA World Cup right now and your friends keep saying “I am in ruins but it is only penalties,” this one’s for you. I wore the Oura Ring Gen 4 through every knockout round to measure what world cup sleep deprivation actually does to a working adult, and the data is uglier than I expected. My baseline before kickoff I had been wearing the Oura Ring Gen 4 for about four months before the tournament started, so I had a clean baseline. My 120-night average sleep score was 84, resting heart rate sat at 56 bpm, and HRV hovered around 62 ms.

Sleep efficiency, normally 88 percent, dropped to 79 percent on nights I went to bed at 3:30am. I want to be specific because the cost is the whole point. The night of the Argentina-France final I went to bed at 5:42am. Oura logged 3 hours and 18 minutes of fragmented sleep across four pieces. Readiness score the next day was 41. I had a 9am client call and at minute 22 I forgot the client name. I still do not know how I got through that call. The emotional part was what I did not expect. I have a 4-year-old daughter, and on day three of this run I snapped at her because she spilled cer
