We were on a college summer camp on Rottnest Island in the middle of the Indian Ocean, well only 18 kilometres from Fremantle, Western Australia, but one of the girls had to be airlifted off by helicopter as she had heatstroke. Happy days – when we emigrated to Australia in 1964 nobody worried about skin cancer or staying hydrated. Fortunately my parents were aware the sun was hot. Dad was out in Egypt after WW2 before he was demobbed and told of ’idiots’ being stretchered out with third degree burns after sun bathing. Fortunately my parents avoided the beach after being taken to Scarborough Beach by our sponsors on our first day in Australia. Huge waves and hot sand did not appeal and we went to pleasant shady spots by the River Swan.

Unfortunately school outings were gloriously free of sun hats and sun lotion and I recall an early outing when we spent the whole day on the beach and next day my nose peeled and bled! Outings with youth groups on hot days were often followed by me feeling sick the next day; setting off without any money and probably a picnic with a plastic bottle of cordial, I obviously didn’t drink enough. At school we did have plenty of water fountains, I didn’t spend my whole time dehydrated, but my sister recalls that if you were thirsty when you were out you stayed thirsty. I’m sure other people were buying bottles of coke and cool drinks of lurid colour, but we were not.

Our current heatwave has brought endless dire warnings of the dangers of going out – or staying inside homes not designed to cope with hot weather. Modern parents never let their children out without a bottle of water, but they should not panic – if Prince George could sit in the heat of Wimbledon dressed in a jacket and tie there is no need to pamper children.
