I know that a lot of you are worried about this heatwave but please don’t panic.
My own children went to school in 45+ degrees, that was also accumulative, we don’t have aircon at home, we both work in hospital were we have to wear PPE and since the aircon is for the whole hospital, it can’t be too cold because of elderly and newborn. We found out that there’s only one fan and that’s in maternity, when we were looking for one for a palliative patient.
A lot of our schools, especially primary schools, have a small main building with classes in demountables which don’t have aircon but ceiling fans! Very useful /s
As I have said on so many previous threads, and I think that having lived through extreme heats (every year) and had to work and had to send children to school, I know a small amount about it:
wear lawn or thin cotton
keep curtains closed
if you aren’t at work, take a siesta if possible
drink iced drinks, preferably water, sipping every few minutes
stay downstairs
sleep downstairs
open windows at the coolest time, usually about 2am to air out the house, especially the upstairs windows - I did tell you to take a siesta if you can!!
If you don’t already own thermal backed curtains, buy some! They keep heat out as well as cold!!
Unfortunately in the UK, you have double glazing! Made to keep heat in!!
