Similar, I also went to Seville and nearby cities. It was March and close to 30c. Despite precautions I got heat exhaustion, and the hotel desk thought I was crazy for asking for air-conditioning to be turned on in my room. I feel the same burning in summer weather usually but it was extra intense in Spain. Any idea what causes the burning and how to reduce it? I did apply sunscreen but that did nothing to alleviate burning
