And that makes a big difference.

It probably doubles the mortality that we would expect to see from such an event.

Yes, Adam, that's right.

So this heatwave is a bit different to some of the others we've experienced in recent years in that it is much more humid this time around.

And a more humid heatwave is more dangerous because it feels hotter.

We've got this feels-like temperature, which is often quoted

And the reason for this is that when it's more humid, the body finds it harder to give off heat through sweating because it's more humid air around you.

Yes.

And so it feels a lot hotter and is therefore more dangerous.

We've seen the records broken for warmest night across the country as well.

And yes, that makes it really hard to sleep.

I know I struggled to sleep last night when the temperature doesn't drop below 20 degrees.

We call it a topical night.

And we're seeing more and more of those happen.

And we'll continue to see more of those in the future as well.

I think those who've got air conditioning will be feeling rather smug at the moment that they can enjoy the cooler temperatures.

But no, I think adaptation is a key issue for us to learn how to deal with heat.

I think that's particularly true for people's workplaces, which are not designed necessarily for the hot temperatures and they can't be as productive when it's so hot.

I think it's an issue for our hospitals, you know, trying to recover from surgery on a hot hospital ward is not going to be much fun.

And for our schools as well, we've already seen lots of schools shut at the moment.
