The Spanish State Meteorological Agency (AEMET) has issued severe weather alerts across key holiday hotspots, including Andalusia, Murcia, and the Balearic Islands.

These warnings include red and orange alerts for heat, as well as one for the Saharan dust haze in parts of eastern Spain and the islands.

Don’t jump into a cold shower after sun exposure

The expert warns UK travellers coming to Spain that a sudden temperature drop can “shock your system”.

She has, instead, recommended cooling down gradually, using lukewarm water and cooling cloths.

Don’t rely on fans alone

While they can be a useful tool, fans can also circulate hot air once the room temperature exceeds 35C.

These should be combined with cold water bottles, mist sprays, or damp sheets for better results.

Avoid rich, salty meals during the day

Digesting heavy foods can sometimes raise your body temperature. Travellers should try eating light, water-rich snacks like fruit, salad and yoghurt.

Don’t leave bottled water or tech in direct sunlight

Plastic bottles may leach chemicals in extreme heat, and devices left on sun loungers can overheat quickly or become damaged.

Don’t walk barefoot on pool tiles or roof terraces

Surfaces can reach “scorching” temperatures and cause burns. The expert has called on Brits to always wear sandals or flip-flops, even for short distances.

Avoid napping in non-air-conditioned rooms

Sleeping in extreme heat can increase your risk of heat exhaustion. If your room doesn’t have AC, take your nap in the morning, not the afternoon, Jessie Chambers has advised.

Don’t assume it cools off after sunset

Evenings can still hover above 30C, especially inland.

To combat this, she had told tourists to avoid long walks after dark unless essential, and to keep water with them at all times.
