This article by the Daily Mail is completely over the top. Read it and decide for yourself!
The temperature in a car that has been in the sun is no guide – it’s always inflated. Common sense in hot countries is to open the doors and wait before you enter the car. Another option is to turn on the aircon and wait.
Local people keep out of the sun between noon and 5.00 PM. Always wear a hat & use high factor sun screen. Drink lots of water and cut down on the booz in the heat. Finally, be careful going from aircon to high external temperatures – do it slowly and give your body a chance.
The best time to swim in the Mediterranean in August is either 7.00 AM or 7.00 PM. If you’re a morning bird, I might see you there.
It would be better if the Mail gave some sound advice rather than hype that captures headlines.
