Why Football Players Don’t Drink Water During Games

Anyone who has watched a match closely has probably noticed it. A player grabs a bottle, takes a mouthful, swishes it around, then spits it straight onto the grass. No swallow, no gulp, nothing that looks like actual drinking. It is easy to conclude that footballers simply do not drink water while they play.

That conclusion is wrong, but the instinct behind it is understandable. Professional footballers do drink water and other fluids during matches. What they avoid is drinking the way people do off the pitch, in long, satisfying gulps whenever they feel like it. The difference comes down to timing, volume and a surprising amount of sports science.

Why Do People Think Football Players Don’t Drink Water?

The belief mostly comes from what fans actually see on screen. Television cameras catch players swilling liquid around their mouths and spitting it out, especially during high-profile tournaments. Because that gesture looks so different from normal drinking, it gets read as players avoiding water altogether.

There is also a structural reason. Football, unlike sports with regular timeouts, gives players very few natural pauses. A goalkeeper’s water break here, a break in play for an injury there and half time are usually the only clear windows. Compared to basketball or American football, where players can drink between almost every stoppage, footballers genuinely do drink less often during play. That difference in frequency, not an outright avoidance, is where the myth took hold.

Do Football Players Really Avoid Drinking Water?

No. Research on top-level match hydration makes clear that fluid intake is limited by opportunity, not by choice. Sports scientists at the Gatorade Sports Science Institute note that the window for fluid intake in football is largely restricted to half time or an unscheduled break, such as an injured player receiving treatment. Players are not turning water away. They simply cannot stop and drink whenever they want, because the game keeps moving.

This is one reason match-day hydration is genuinely difficult to get right. A study of adolescent Spanish soccer players found that a meaningful share of players, around 10 percent, reported not drinking any water at all during a match and researchers linked poorer hydration to how much time players actually spent on the pitch. Elite players are better supported than amateur ones, but the underlying constraint, limited stoppages, applies at every level.

How Football Players Stay Hydrated Before Matches

Because in-game drinking is so restricted, most of the real hydration work happens before kickoff. Sports scientists at Barça Innovation Hub recommend that pre-match hydration become an automatic habit, with small, regulated sips taken over the 60 to 90 minutes before exercise rather than one large drink right before the whistle.

Clubs also build hydration into the days leading up to a match. Players are encouraged to drink consistently through the week, not just on match day, so they start the game already well hydrated rather than trying to catch up. Weighing in before and after training sessions is a common method clubs use to track how much fluid an individual player typically loses, since sweat rates vary a great deal from person to person.

Why Players Drink Small Amounts During Games

When footballers do get a chance to drink mid-match, they tend to take quick, small amounts rather than long drinks. There are a few practical reasons for this.

• Limited time. A drinks break might last seconds, not minutes, so there is no time for a slow drink.
• Comfort during sprinting. Taking in a large volume of liquid while repeatedly sprinting, jumping and changing direction can leave a player feeling bloated or heavy.
• Digestion speed. Swallowing a sugary sports drink takes time to process, which is not ideal seconds before another burst of running.
• Habit and training. Players are coached from a young age to sip rather than gulp, so the pattern becomes automatic by the time they reach the professional game.

What Footballers Drink During Matches

Water is only part of the picture. Many players use isotonic sports drinks that combine water with carbohydrates and electrolytes, mainly sodium, to replace what is lost through sweat. According to Barça Innovation Hub’s sports science team, drinks containing carbohydrates and salts are considered ideal for athletes because they also restore electrolytes, which affect functions such as muscle activity.

This is different from energy drinks, which is a distinction worth making because the two are often confused. Energy drinks may contain water, sugar and stimulants such as taurine or high doses of caffeine and sports science guidance generally advises against them during football activity, unlike balanced isotonic drinks designed for athletic rehydration.

The mouth-rinse technique explained

This brings us back to the swishing and spitting that started the myth in the first place. The technique became widely recognised after the 2018 World Cup, when players such as Harry Kane and Cristiano Ronaldo were seen doing it on camera. Rather than swallowing a carbohydrate drink, a player rinses it around the mouth for roughly five to ten seconds before spitting it out.

The reasoning is not about avoiding hydration. Research summarised by sports outlets suggests that carbohydrate exposure in the mouth can activate receptors linked to motivation, reward and motor control in the brain, giving a short mental boost without the time cost or bloating of actually swallowing. It is a performance tool used alongside proper drinking, not a replacement for it. Players still hydrate fully at other points: usually before kickoff, at half time, after the match and during any official cooling breaks.

The Role of Sports Science in Football Hydration

Top clubs and federations now treat hydration as a measurable, individualised part of performance preparation rather than a matter of instinct. Teams monitor body mass changes before and after sessions to estimate sweat loss and some use hydration testing to help players understand their personal fluid needs under different conditions.

Governing bodies have also changed match rules in response to heat research. FIFA has historically triggered cooling breaks when the Wet Bulb Globe Temperature exceeded certain thresholds, a practice that began at the 2014 World Cup in Brazil. For the 2026 World Cup, FIFA moved to a standardised approach: mandatory three-minute hydration breaks in every match, scheduled around the 22nd minute of each half, regardless of temperature, stadium roof, or climate control. FIFA said the change was designed to ensure equal conditions for all teams in all matches, replacing a system where breaks depended on referee judgment and weather thresholds. It marked the first time hydration breaks were built into every game rather than reserved for extreme heat.

Nutrition strategy has also become part of the science. Research on elite hydration practices notes that high-carbohydrate strategies, both in the days before a match and during play, have been shown to improve performance, working alongside fluid intake rather than separately from it.

How Dehydration Affects Football Performance

The stakes for getting hydration wrong are higher than many fans realise. Losing as little as 2 percent of body mass in fluid has been shown to impair football-specific performance, including intermittent high-intensity sprinting and dribbling skills. That is a small percentage in absolute terms, often under a kilogram for many players, which shows how sensitive performance is to fluid balance.

Dehydration does not only affect the legs. According to Barça Innovation Hub, fluid loss can reduce cognitive performance and slow reflexes and coordination, which can prove decisive in the closing minutes of a match when concentration and quick decisions matter most. Heat adds further risk. Athletes training or playing in hot conditions can lose between one and two litres of sweat per hour and most people drink less than they lose, which is why heat-related illness remains a genuine safety concern in football, not just a performance issue.

Fluid loss (% of body mass)	Typical effect
Under 2%	Minimal measurable impact for most players
2% or more	Impaired sprinting, dribbling accuracy and endurance
5% or more	Significant performance decline; rapid, structured rehydration recommended

Hydration Tips for Young Football Players

Young and amateur players do not have club nutritionists monitoring their sweat rates, but the same principles apply on a smaller scale.

1. Start hydrated. Drink consistently in the 24 hours before a match or training session, not just in the final hour.
2. Sip before kickoff. Small, regular sips in the 60 to 90 minutes before play work better than one large drink right before the whistle.
3. Use every stoppage. Take advantage of any break, whether it is an injury pause, a drinks break, or half time.
4. Replace salt as well as water. Adding a small amount of salt to water, or using an isotonic drink, helps replace sodium lost through sweat.
5. Rehydrate properly afterward. If body weight drops noticeably during a session, replacing lost fluid and electrolytes afterward supports recovery for the next match.
6. Avoid energy drinks. Products built for energy rather than hydration are not designed for the demands of football activity.

Final Thoughts: The Truth About Footballers and Water

Footballers are not avoiding water. They are managing it under conditions that make normal drinking impractical for large stretches of a match. The habits that look strange from the stands, quick sips, mouth rinsing, spitting, exist because sports science has shown they work better within the limits the game imposes. Real hydration happens mostly around the match: in the hours before kickoff, at half time, during any hydration breaks and in the recovery period afterward.

As football rules continue to adapt, including FIFA’s move toward mandatory hydration breaks, the gap between what fans see on screen and what is actually happening physiologically should keep narrowing. The science has not changed much. What has changed is how much room the game gives players to act on it.

Frequently Asked Questions

Do footballers drink water during matches?

Yes. They drink during natural stoppages such as injuries, drinks breaks and half time, but opportunities during open play are limited by the flow of the game.

Why do footballers spit out water instead of swallowing it?

This is usually the mouth-rinse technique, where a carbohydrate drink is swished in the mouth for a few seconds for a short mental performance boost, then spat out to avoid the time and bloating cost of swallowing during play.

How much water should a footballer drink before a match?

General sports science guidance favours small, regular sips over the 60 to 90 minutes before kickoff rather than one large drink, alongside consistent hydration in the days leading up to the match.

What do professional footballers drink during games?

Water and isotonic sports drinks containing carbohydrates and electrolytes such as sodium, which help replace what is lost through sweat.

Can dehydration really affect performance in football?

Yes. Research shows fluid loss of as little as 2 percent of body mass can impair sprinting, dribbling and decision-making late in a match.
