1. By wearing a silly hat I bought at an airshow recently - just like a Japenese ww2 soldier's hat with a long baseball cap style peak and material at the sides and back covering ears and neck. In light camouflage colours. £5 - no more headaches since!
2. Ambre Solaire spray-on factor 20 for sun protection - dries clear.
3. Large flask of ice-cold water
4. Go home lunch time (that's dinner time to you chav northerners
), have a shower, sit in front of the portable air conditioner.
5. Use air-con in the car to cool down every couple of hours.
6. And yes - start early where possible.
Monday - full day starting at 6 am finishing at 4pm
