About Blue Lights and Black Nails: 4 Things That Boost Footballers’ Performance
Modern football is a game of fine margins and non-stopping innovation. Players and coaches are constantly experimenting with new methods to gain even the slightest details on the pitch. From high-tech sleep aids to old-school recovery tricks, today’s stars will try almost anything in the pursuit of peak performance. Here are the most popular things that boost footballers’ performance.

Nose Strips
Those little bandage-like strips on players’ noses aren’t a fashion statement – they’re a breathing aid making a comeback. Nose strips gently pull the nostrils open to improve airflow, which can enhance oxygen intake and even sleep quality for players. Several FC Barcelona players were recently spotted wearing them during travel, reporting that “you really sleep better” with the strips on. It’s all about marginal gains: better rest means better recovery, which means better performance on the field. Even detail-obsessed coaches like Hansi Flick have reportedly encouraged their squads to use nose strips to boost overnight recovery.
Blue Light Blocking Glasses
When evening falls, some pros put on blue light-blocking glasses – typically with orange-tinted lenses – to filter out the harsh glow of smartphones and stadium lights. The science is simple: less blue light means more melatonin production, leading to deeper sleep and faster recovery. Manchester City star striker Erling Haaland is one believer. He credits his amber lenses worn before bed with helping him get “deeper and better sleep,” which in turn squeezes out “a few percent more power” in his game. By cutting down screen-time glare, players wake up fresher. In an era when reaction time and recovery are everything, blocking out blue light has become a crucial part of many footballers’ routines.
Black Nail Polish
Cristiano Ronaldo’s latest style isn’t about fashion – it’s about body health. The Portuguese icon has been seen with his toenails painted black, a trend quietly spreading among professional footballers. The reason? A layer of hard polish creates a shield that keeps nails from cracking under stress and prevents bacteria and fungus from thriving in sweaty boots. In Ronaldo’s case, even a sauna recovery photo sparked conversation when fans noticed his black pedicure .But trainers confirm it’s a smart protective measure: strong, fungus-free toes mean one less thing to worry about during explosive sprints or sudden stops. It’s a subtle example of the extreme lengths players go to look after every inch of their body.

Ice Baths
Nothing says dedication like submerging up to your waist in freezing water after a match. Ice baths have become standard ritual in locker rooms around the world – and for good reason. The frigid plunge constricts blood vessels and reduces inflammation, helping muscles recover faster after the 90-minute onslaught. Superstars absolutely swear by it. Erling Haaland, for instance, soaks in ice regularly and calls it key to gaining “a few percent more” performance. Cristiano Ronaldo’s commitment is legendary: he once took 3 A.M. ice baths at Real Madrid’s training ground. He prioritized recovery over sleep or even an awaiting supermodel girlfriend. From Sunday league to the World Cup, ice baths are now a staple of modern sports science. The freezing plunge helps reduce inflammation and muscle soreness after intense games. It’s a quick torture session that leaves players fresher, faster, and ready to go again.
