Prepare to feel like a human heart monitor when your team plays in the 2026 World Cup final. According to science, watching high-pressure matches can significantly increase your heart rate and stress levels.

A recent study from Bielefeld University found that fans' physiological stress jumps by about 41% during a soccer final compared to an average day. For those cheering on German club Arminia Bielefeld, the heart rate soared from 70.9 beats per minute before the match to 78.7 beats per minute during it.

Where you watch matters too. Fans in the stadium experienced a higher average heart rate of 94.2 beats per minute compared to those watching on television, who clocked in at 79.4 beats per minute. A first goal? That's even more intense, with stadium fans' hearts racing up to an impressive 108 beats per minute.

Alcohol doesn't help. Drinkers saw their heart rates increase by about 5% during the match and nearly 12% after scoring that first goal. This emotional state can exacerbate cardiovascular strain, especially for those with preexisting conditions. So next time you're rooting for your team, remember to hydrate and maybe lay off the ale.
