Of course, the best way to avoid the heat is not to go out in it.
And in Seville, many of the bars and restaurants close during the afternoon.
Behaviour has changed over the centuries and the siesta is part of Spanish life. Locals seem to go out late, after 8pm, once the heat has abated.
Dr Mehri Khosravi is an expert in heat at the University of East London and says Londoners need to change their attitude to extreme heat and we can learn from our continental neighbours.
“We need to adapt in terms of building design. But we need to adapt our behaviour especially in the UK where the culture of heat is missing. People in the UK treat heat as a nice thing – they arrange BBQs and leisure activities but we need to start treating as a risk like they do in other countries.
“In the hottest hours of the day, they pause some activities and then they resume it in the evening.
“Or when you walk into a street during the day, and the sun is out they never open the windows. Curtains are shut so they don’t let the heat in. They use night for ventilation.
“These simple changes in behaviour, the changes in routine, can make a big difference in how to deal with heat and we can learn from those countries.”
