Estadio Azteca altitude guide: How to stay safe 2,200 metres above sea level

England just about made their way into the round of 16 at World Cup 2026, getting the better of a determined DR Congo side in a 2-1 comeback win thanks to a late brace from captain Harry Kane.

After the striker's heroics, the Three Lions are set to face co-hosts Mexico at the legendary Estadio Azteca in the early hours of Monday morning UK time (fear not, pubs will be open late).

However, while El Tri's impressive record at the tournament so far – which features four wins, eight goals scored and zero conceded – will be the focus in the buildup to the knockout tie, the unique conditions at the ground could be a major factor.

The Azteca sits 7,220ft (2,240m) above sea level in Mexico City, an altitude that will have a significant physical impact on players and fans alike, and it is important that visitors know how to stay safe and healthy.

Here, Football Ground Guide provides an Estadio Azteca altitude guide, covering what you need to know about how to stay safe 2,200 metres above sea level.

What impact does the altitude at Estadio Azteca have on the body?

At the type of high altitude that will await in Mexico City, the air is thinner, meaning that it will take more breaths to bring the amount of oxygen required into the bloodstream.

To make matters worse for those not acclimatised to the conditions, the barometric pressure is much lower at altitudes above 2,000m, which reduces the efficiency of the body to transport oxygen and therefore a person's aerobic capacity.

Altogether, this causes an increased heart rate, as well as quicker dehydration, a shortness of breath and a faster onset of fatigue, which can also be more intense than usual.

Additionally, given that the brain needs oxygen to function, headaches, nausea and dizziness are not uncommon, and your sleep is likely to be disrupted on your first night in Mexico City.

As you can imagine, this poses a serious problem for professional athletes aiming to compete at the highest level, but even the average person just visiting for a World Cup game needs to be aware of the meaningful difference that the altitude will have on their ability to function.

How can fans visiting Estadio Azteca stay safe at high altitude?

Arrive early

Staying in Mexico City for a few days before the game would allow the body to acclimatise and produce an increased number of red blood cells, in order to make up for the differences in air density and pressure.

If that is not possible, it is advised that visitors be aware of the risks of altitude sickness and take steps to mitigate the symptoms (headache, fatigue, shortness of breath, disrupted sleep) so that they can enjoy the match properly.

Stay hydrated

Higher altitudes cause the body to lose fluids faster than usual, so it is important to drink three to four litres of water per day – more than you typically would. This will help to maintain proper function of the organs as your system adjusts to the climate.

One popular way to bolster your hydration is by consuming electrolytes, either by adding specialised salts to drinks or by purchasing solutions that are widely available at local pharmacies.

Take care when drinking alcohol

The altitude at the Azteca will make the negative effects of drinking that much worse.

It is suggested that visitors avoid or limit their alcohol intake during their first 24 hours in Mexico City to lower the risk of developing a serious headache, and that they make sure to have plenty of water when going out drinking on matchday.

Eat light

Even the digestive system is impacted by the altitude, and eating heavy meals will make you feel nauseous, potentially ruining the match. Eat light, frequently in order to stay energised and comfortable.

Take things slowly and do not ignore symptoms

Heading to a match at Estadio Azteca is exciting, but make sure to avoid overexerting yourself, especially on day one.

For example, exercising within the first 24 hours of your arrival will make symptoms more likely to occur, so consider taking breaks often and exploring Mexico City in a leisurely fashion.

In that same vein, you should pay attention to how you feel, making sure to hydrate and rest if you experience a persistent headache, and do not hesitate to seek medical assistance.
