So one of the pathways towards heat stroke emanates from the gut.
We see the gut become lower in blood flow and people develop this leaky gut syndrome.
And with a leaky gut in place, what we see is bacteria that should be residing in the gut move into the bloodstream and the body initiates then an inflammatory response to try and resolve those.
It doesn't have sufficient blood flow to send those bacteria to the liver for clearing in that organ.
And this inflammation contributes towards what ultimately can be fatal in heat stroke, which is multi-organ failure.
We know that football matches played in higher heat stress conditions can seem a little bit more passive.
They might be less engaging to the spectator.
Players produce less high-speed running.
They have the capacity still to sprint as fast, but they choose to sprint less frequently.
So we might see in hotter fixtures around 10% less high-distance running.
If you take an average player, it might cover 10km sprinting.
That might drop off by around about 10%.
The approach to the game might change substantially as well.
Although there's some cognitive and decision-making declines that come with heat stress, we know that actually an interesting proxy to that pass accuracy tends to go up when the conditions are hot.
And that reflects players making more conservative passing decisions to retain possession and avoid the need to do lots of high-speed running to recover the ball.
There is a chance, I think the spectator might observe, that the games feel a little bit less thrilling, for want of a better word.
To spend longer periods than FIFA have currently mandated, they have a three-minute cooling break, which potentially is insufficient, and a six-minute break would allow for more meaningful rehydration and cooling.
potentially there is a scenario that we haven't really seen in football in the same way we might have seen it in endurance sports like marathon running, for example, where we receive pictures of a player collapsing in the game and there's a suspension of play.
Perhaps the temperature and the heat stress conditions mean that games are postponed and or delayed in game for substantial periods of time.
All of those are really concerning scenarios.
