AIBU to think school cricket in 37 degree heat is dangerous?

No. But they tend to plan around the hottest times of the day/hottest times of year

Italy has shut schools for the summer Remember Google is your friend

Actually it does. Have you lived for an extended time in hotter climates?

Outdoor work and sport are shifted to early morning or evening. Schools have longer midday breaks, air-conditioned buildings, shaded playgrounds and heat policies. Sports are often cancelled, shortened or rescheduled when heat reaches dangerous levels. People become acclimatized over weeks and months, which improves their ability to cope with heat. Buildings are often designed differently for heat management than UK buildings.

Children in the UK are not acclimatized to these temperatures. Schools often have limited shade and little or no air conditioning. Sports days can involve prolonged exposure, waiting around in direct sun, and repeated physical exertion, and risk of illness rises significantly during activity, especially for younger children.

Ignorant comment.

Hot countries have more heat-aware architecture, which means for example cooler school buildings.

And noone would schedule a match 2 pm in June there.

No it doesn’t… but ‘hot countries’ are acclimatised to the heat..
Many hot countries arrange their day to not be out at the peak of it .. they play sport in the evening AFTER school .. name me a single hot country that plays sport in the heat of the day ? (I’ve lived in Thailand , Malaysia and India - so pretty damn hot in the afternoon)

Life doesn't stop in hot countries

If it’s too hot to walk your dog it’s probably too hot to force children to run around with eggs on spoons.

@TheLightSideOfTheMoon this hits the nail on the head
it’s my kids sports day this week - nothing has been emailed yet but I am hoping that they postpone it - last year was horrendous so so hit. I have never understood why they don’t do this in April/May time before it gets too unbearable.

I used to let DS skive on sports’ day.

He wasn’t athletic, very much an indoor boy and the bullying would increase. Also, it was always hot AF.

He did one on the first year and came home in tears and with heatstroke.
