So those are in competition.

And you can get to the point where this cooling just stops working.

It doesn't do enough.

And that is when it hits performance and obviously carries these health risks as well.

And the worst case scenario is that you get heat stroke, and that can be fatal.

So this is serious stuff.

And beyond the health risks, Oliver talked about how heat can impact the game itself.

So first of all, FIFA have said, look, our top priority is to ensure the health of the players, of the referees, of everybody involved in the World Cup.

And they have introduced for this World Cup, each match, regardless of the temperature, is going to have a cooling break in each half.

But what the researchers are worried about is that they say that the threshold for bringing in really serious mitigations, and that would be delaying or postponing a match, they say that threshold is too high.

So first of all, FIFA have said, look, our top priority is to ensure the health of the players, of the referees, of everybody involved in the World Cup.

And at the moment for the World Cup, that would come in at this wet bulb globe temperature of 32 degrees.

And they have introduced for this World Cup, each match, regardless of the temperature, is going to have a cooling break in each half.

And these researchers say the recommendation should be 26 degrees.

But what the researchers are worried about is that they say that the threshold for bringing in really serious mitigations, and that would be delaying or postponing a match, they say that threshold is too high.

So they are looking for a substantial reduction in that threshold where

Officials can just say, it's too hot, we have to delay this game.

But they also want to have some other changes made too.
