Health tips in the event of a heat wave
• Be aware of the indoor temperature.
The risk of health problems increases as soon as the indoor temperature rises. The risks increase significantly when the outdoor temperature reaches 26 °C or higher for three consecutive days.
• Drink more fluids
Don’t wait until you get thirsty. Eat foods with a high water content, such as fruit and vegetables. Avoid large amounts of sugary drinks and alcohol. Keep in mind that the people around you may need help staying hydrated.
• Create a cool environment
Use curtains, blinds and awnings. Try to stay in the coolest part of your home. Open windows at night, when it’s cool.
• Find ways to cool down
A cold shower is the most effective way. A damp towel around the neck is also an option. Wear loose-fitting clothes made of natural materials. They are cooler than tight-fitting clothes made of synthetic materials.
• Take it easy
Avoid physical exertion during the hottest hours of the day.
• Store medications correctly
Store medications at 25 °C or less, or in the refrigerator. Read the storage instructions on the package.
• Be aware of your health and that of others
Warning signs may include elevated body temperature, increased heart rate, increased respiratory rate, sudden-onset dizziness and unusual tiredness. A dry mouth and decreased urine output may be signs of dehydration. If you are taking medication – diuretics, for example – the dose may need to be adjusted. Contact your healthcare provider for advice concerning your health or that of your family.
