Summer in the Vega Baja region frequently brings temperatures above 35°C. At SanySa, we understand that extreme heat is not just uncomfortable — it is a real health risk that requires prevention and expert response. Heat stroke is a medical emergency that can be prevented with clear information and precise action.

What exactly is heat stroke?

Heat stroke occurs when body temperature exceeds 40°C and the body loses its ability to self-regulate. Unlike sunburn —which mainly affects the skin and head— heat stroke compromises the entire body and can damage vital organs if not treated immediately.

The most vulnerable people are children under 5, adults over 65, those with chronic conditions, and anyone doing intense physical activity outdoors. But anyone can be affected if exposure is prolonged.

Symptoms: what your body tells you not to ignore

Recognising the signs in time makes the difference between a scare and a serious emergency:

• Elevated body temperature (above 40°C)
• Hot, red and dry skin — the body has stopped sweating, indicating the cooling mechanism has failed
• Severe headache and rapid pulse
• Confusion, dizziness or loss of consciousness
• Nausea and vomiting
• Muscle cramps after prolonged exposure

If confusion or loss of consciousness appears, this is a medical emergency: call 112.

Prevention: the most effective tool

As with many areas of health, prevention is always better than cure. These are the measures we recommend from our practice:

1. Constant hydration: drink water every 20-30 minutes, even without thirst. Avoid alcohol and caffeinated drinks, which promote dehydration.
2. Avoid exposure during central hours: between 12:00 and 17:00 the sun is most dangerous. If you must go out, seek shade frequently.
3. Light clothing and light colours: cotton and linen allow breathing. Wear a hat and sunglasses.
4. Protect the most vulnerable: ensure children and elderly drink water regularly. Their thirst sensation is lower and they don’t always ask for what they need.
5. Never leave anyone inside a parked vehicle, not even for a few minutes. Interior temperature can exceed 50°C in minutes.
6. Adapt physical exercise: train during the coolest hours and reduce intensity. Your body needs to acclimatise to the heat.

What to do if you suspect heat stroke?

Act without hesitation. Speed is your best ally:

1. Call 112 if there is confusion, fainting or very high temperature.
2. Move the person to a cool, shaded place.
3. Lay them down with legs slightly elevated.
4. Cool the body: damp cloths on neck, armpits and groin. Use a fan if available.
5. Offer water in small sips if the person is conscious. Do not give liquids to someone unconscious.
6. Monitor until medical help arrives.

When to seek emergency care?

Seek emergency care immediately if the person shows:

• Temperature above 39.5°C that does not respond to cooling measures
• Altered level of consciousness (confusion, drowsiness, fainting)
• Seizures
• Dry, hot skin despite being in a cool environment
• Persistent vomiting preventing oral hydration

At SanySa in Almoradí, we have an emergency service and a medical team prepared to handle heat-related emergencies. Do not wait for symptoms to worsen: prompt care makes the difference.

💡 SanySa Tip

Prepare a homemade rehydration bottle if you’ll be outdoors for more than an hour: 1 litre of water + 1 teaspoon of salt + juice of half a lemon. Replace electrolytes, not just fluids.
