Heatstroke

Heatstroke is a disruption to the body's temperature regulation system. It occurs when the body is no longer able to cool down properly.

Heatstroke can occur even without direct sun exposure. Sunstroke occurs when the head is exposed to the sun without protection, and can lead to heatstroke.

Heatstroke can occur more quickly in infants and the elderly during periods of extreme heat, especially in humid, windless conditions, but also in people engaging in sports who are unable to compensate for the water lost through perspiration.

Heatstroke can be fatal and must be treated quickly by medical staff to prevent any neurological after-effects.

Symptoms

Can be mild: cramps, headache, dizziness, unusual tiredness or generally feeling unwell. In this case, you should rest in the shade in a cool place and drink water until you recover completely.

In the event of more serious signs of confusion and altered consciousness, vomiting, call 112. Get the person to lie down (on their side if unconscious or vomiting) somewhere well ventilated and in the shade. Apply damp cloths to their legs and arms.

How to avoid heatstroke

• Never leave a baby, a vulnerable person or an animal in a car in the sun, even for a few minutes.
• Never leave a baby, a vulnerable person or an animal in direct sunlight during hot summer weather.
• Do not let children play in poorly ventilated or excessively hot places.
• Avoid covering children too tightly.
• Wear light clothing during the hottest periods.
• Drink at least 1.5 litres of water per day.
• Avoid alcohol: it promotes the loss of liquid and salt through urine.
• Spend several hours per day in cool areas or in the shade: close doors, windows and shutters during the day.
• Avoid strenuous physical activity during the hottest hours of the day.
• Cool off with water activities or by taking short showers or partial baths.
• Pay daily visits to elderly people you know who live alone. Make sure they have plenty of mineral water and that they are drinking enough of it.
