Heatwaves: how to protect elderly and dependent people at home

29 Jun 2026 · SUR.lu Team

Summary

As hot weather arrives in Luxembourg, here are the simple actions that help protect elderly and dependent people from dehydration and heatstroke.

Hot weather: stay alert for your loved ones

Every summer, heatwaves are a real danger for elderly, isolated or dependent people. With age, the body senses thirst less well and regulates its temperature less effectively: dehydration and heatstroke can set in quickly, sometimes with no obvious warning.

Why elderly people are more vulnerable

  • The sensation of thirst fades with age — people drink less, even when the body needs it.
  • The body sweats less efficiently and regulates temperature less well.
  • Some treatments (diuretics, heart or blood-pressure medication) increase the risk of dehydration.
  • People with reduced mobility cannot always cool down or drink on their own.

Warning signs to know

Seek advice without delay if you notice: unusual tiredness, headaches, dizziness, a dry mouth, confusion, cramps or a fever. Heatstroke is a life-threatening emergency: if there is a high temperature, disorientation or loss of consciousness, call 112.

Everyday tips

  • Encourage regular drinking, without waiting for thirst: water, but also cold soups, water-rich fruit and dairy.
  • Keep the home cool: close shutters and windows during the day, ventilate at night, use a fan with a damp cloth.
  • Plan outings for the coolest hours, early morning or evening.
  • Wear light clothing and cool the skin with a water spray or a damp cloth.
  • Review medication with the doctor or pharmacist during hot spells.

How your SUR.lu team helps

During heatwaves, our caregivers pay particular attention to the people we support: monitoring hydration, adapting care and alerting the family or doctor at the first worrying sign. Never hesitate to flag a concerning situation to us — a single phone call can prevent a hospital admission.

In Luxembourg, the Ministry of Health's heatwave plan (Plan canicule) is activated every summer: check in regularly on isolated relatives and don't wait to ask for help.

In an emergency, call 112.
