Heatwave: seasonal precautions

In old age, the body perspires less and consequently has difficulty maintaining a temperature of 37°. This can cause a rise in body temperature leading to a risk of heat stroke (hyperthermia, where the temperature rises above 40° and consciousness is impaired).

In children and adults, the body perspires a lot to maintain the correct temperature, but this leads to a loss of water, risking dehydration.

There are some simple steps you can take to help avoid problems, particularly at the beginning of a period of hot weather. It is important to prepare before you notice any signs that your body is suffering, even if these signs seem insignificant.

• Drink plenty of water
• Cool down regularly
• Avoid going out during the hottest hours of the day (10 am to 6 pm)
• Stick to non-strenuous activities during the hottest part of the day
• Keep your home cool
• Never leave anyone, particularly a child, alone in a car, even for a very short period, since the temperature inside can rise very quickly (animals should not be left in vehicles either)

• Wear long-sleeved clothing, a wide-brimmed hat and sunglasses
• Opt for category 3 sunglasses – note that some sunglasses, even those with dark-tinted lenses, do not offer protection against UV rays
• In addition to these measures, use sun cream on uncovered areas
• Never expose children under 12 months old to the sun

• When the UV index is between 3 and 7: use a sun cream with a minimum of SPF 30+
• When the UV index is between 8 and 10: use a sun cream with a minimum of SPF 50+
• When the UV index is 11 or higher:
  • Avoid exposure to the sun
  • Use a sun cream with a minimum of SPF 50+

If you feel unwell (on behalf of yourself or someone else who needs assistance) contact the Fire and Emergency Service by dialling 112.
