Dehydration on holiday in Mallorca

Recognise fluid loss and act fast

4 min read Henrik VenusHenrik Venus, physician Updated: August 2026

Dehydration — the body's lack of fluid — is a frequently underestimated risk, especially during the hot Mallorca summer. As a private medical house-call service in south-west Mallorca (Paguera, Port d'Andratx, Calvià), I treat dehydration / fluid loss directly at your hotel or finca — at flat rates of 250–450 €, and I call you back personally. At temperatures above 30°C / 86°F the body can lose up to 2 litres of sweat per hour. If this loss is not replaced, serious symptoms can develop quickly — and dehydration often goes hand in hand with sunstroke on holiday in Mallorca.

Symptoms

  • Strong thirst and dry mouth
  • Headache and dizziness
  • Tiredness and exhaustion
  • Dark urine (concentrated)
  • Dry skin, sunken eyes
  • Muscle cramps (calves, thighs)

First aid

  1. 1 Move to a cool place immediately
  2. 2 Drink water slowly (small sips)
  3. 3 Oral rehydration solution or isotonic drink
  4. 4 Salty snacks (crackers, pretzel sticks)
  5. 5 Rest with the legs elevated
  6. 6 Additionally apply cool compresses to forehead and neck

Prevention

Prevention tips

Drink 2.5–3 litres of water daily, increase to 4+ litres in heat or during sport. Avoid alcohol and caffeinated drinks. Wear a light hat and plan shaded breaks. If you experience acute weakness or circulatory problems, I can come to you with a house call in Palmanova.

Frequently asked questions

How much water should I drink on Mallorca?
In summer at least 2.5–3 litres per day; in heat and during activity rather 4+ litres. Listen to your body — thirst is already an early warning sign.
Does beer count as fluid intake?
No, alcohol is dehydrating. When drinking beer the body actually loses more fluid than it takes in. For every beer, drink at least one glass of water.
What is better — water or sports drinks?
For normal hydration, water is enough. With heavy sweating (sport, sun) electrolytes matter — either isotonic drinks or water with a pinch of salt and some juice.
When does dehydration become dangerous?
From a fluid loss of about 5% of body weight (at 70 kg = 3.5 L). Then circulatory problems, impaired consciousness and kidney issues are possible.

For acute dehydration, examination and treatment are part of the house-call services — the flat-rate prices from €250 to €450 are transparent. My service base is Port d'Andratx, covering the whole southwest of Mallorca.
