Heatwaves are becoming increasingly common and can pose serious health risks for older adults. As we age, the body’s ability to regulate temperature decreases, and the sensation of thirst becomes less noticeable, increasing the risk of dehydration and heat-related illnesses.
Why are older adults more vulnerable?
Ageing affects the body’s natural cooling mechanisms. Chronic medical conditions and certain medications may also reduce the body’s ability to cope with high temperatures.
Essential precautions during a heatwave
- Drink water regularly throughout the day, even if you do not feel thirsty.
- Avoid alcohol and limit sugary or caffeinated drinks.
- Wear lightweight, loose-fitting and light-colored clothing.
- Keep your home cool by closing blinds during the hottest hours and ventilating in the early morning or evening.
- Avoid going outside between 11 a.m. and 6 p.m.
- Cool yourself regularly with a lukewarm shower, a damp cloth or a cooling spray.
- Eat light meals rich in fruits and vegetables.
- Stay in regular contact with family members, friends or neighbors, especially if you live alone.
Warning signs
Seek immediate medical attention if you experience:
- high fever
- severe headache
- unusual fatigue
- confusion or disorientation
- dizziness
- breathing difficulties
- loss of consciousness.
These symptoms may indicate heatstroke, a life-threatening medical emergency.
Key takeaway
Simple daily precautions can greatly reduce the risks associated with extreme heat. Staying hydrated, keeping cool, avoiding strenuous activities and maintaining social contact are essential for protecting older adults during heatwaves.
