I now understand why siestas exist. It´s because Summer is so damn hot that your body literally needs to recharge. The heat in Madrid is insane. I leave my house around 7.45am and while waiting for the train, I realize I´m already sweating!
Fortunately we have a reduced work schedule during the summer months whereby we leave work by 3:30pm to go home and have lunch.
UNfortunately, I have no air conditioning at home! It would be better to eat lunch at work with air conditioning than to be in my hellish hot oven of a house! But you eat a bit of food and lay down on the sofa and VOILA! Siesta! OLÉ!!!
