Well, fur with clothing don’t help to sweat to cool one down.

Sun has no mercy.

South Europe Horse Pointers:

Drink water, (duh). Or beer.
Wear as little as possible, BUT… wear white or clear clothes. It’s like magic.
Linen is your friend, avoid wool like the plague.
Wear hats. Panama-style are good. Caps are ok too.
Should you do physical exercise, do it in the morning, as early as possible, and try to moderate towards mid-day.
Never try heavy physical exercise between 13:00 and 19:00 (aprox) if possible.
Seek for shade, shade is good. Direct extended exposure to sunlight is bad.
Ideally, try to stay somewhere under dedicious trees and green grass for shade.
Go to bodies of water, the air is more humid and therefore colder than anywhere else.
The best place to rest would be somewhere with some light wind. Winds steal your heat, lethal during winter, a blessing on summer.
If staying indoors, go for buildings with the whitest exteriors and avoid the attic. A single floor building counts as attic too.

I once tried to ride my bike over a mountain in the tropics without bringing water. I had to turn back when I became all shaky about halfway up, and drank over three liters (almost a gallon) when I got home. Dehydration can be quite fatal!

We, 39º at the shade:

Pff, weak.

The other half carry more beer than provisions.

Might wanna drop the scarf next time, that can’t be helping the heat situation.

Being through the desert on as a horse with no sense.
