I am sure here are superhumans among us, but do you really work in this weather at home? Most houses in Uk have no aircondition and the electric one is not useful for whole day. I have Dyson very strong one but still, my house gets very hot after about 6-7pm thats when i need to get shower often and my brain is just off. I can manage to do simple tasks, but i cant manage to do more complex ones. I am supposed to handle in work tomorrow and i still didnt start.
In my opinion, Uk should introduce siesta times or days off, which would be compensated for longer woring hours when its not hot, so it does not hurt economy, but weather is changing, in 10 years time we can face 40’s and if you look at latino hot countries, they have this system for reasons.

People just should have days off because many are much less productive anyway, ( unless living in new appartments with aircondition) , and have no health issues. Many of us have, which makes it difficult. My neighbour has heart condition, i have allergies and take antihistamines, my roommate as well, plus she is underroof so its roasting there.
