Health experts are urging people across Spain to take extra precautions as bouts of extreme temperatures get underway for the summer season.

It follows a heatwave this week that saw highs of over 45C in parts of Andalucia.

Doctors warn that heatstroke is a medical emergency and should never be dismissed as simply feeling overheated.

The first rule is to do with staying hydrated, with experts warning ‘don’t wait until you feel thirsty.’

During extreme heat, the body loses large amounts of fluid through sweat, so experts recommend drinking water regularly throughout the day, even if you don’t feel dehydrated.

Alcohol, sugary drinks and excessive caffeine should also be avoided as they can contribute to dehydration.

Medical professionals advise sticking mainly to water during heatwaves.

People are also urged to stay out of direct sunlight between midday and 6pm, when temperatures and UV levels are at their highest.

Exercise, long walks and physically demanding work during these hours significantly increase the risk of heat-related illness.

If you do need to go outside, wear loose-fitting, lightweight clothing, use a hat, seek shade wherever possible and apply sunscreen. Light-coloured clothing can also help reflect heat.

Doctors say everyone should know the warning signs of heatstroke, which include a very high body temperature, hot skin, confusion, fainting, vomiting, a rapid pulse and difficulty responding normally.

Anyone showing these symptoms should receive immediate medical attention.

While waiting for emergency services, move the person to a cool place, remove unnecessary clothing and apply cool, wet cloths or water to the neck, armpits and groin.

If the person is confused or unconscious, do not give them anything to drink.

Children, elderly people, pregnant women and those with chronic health conditions are particularly vulnerable during periods of extreme heat.
