Heat Retention in Cars During Summer: A Silent Threat
As temperatures soar in the UAE during the summer months, the risk of heat-related illnesses increases dramatically—especially inside closed vehicles. The “greenhouse effect” within parked cars can turn them into dangerously hot spaces within minutes, putting vulnerable individuals like children, elderly people, and even pets at serious risk.
Dr. Youssef Aboud, Consultant and Head of the Emergency Department at Fakeeh University Hospital, highlights the critical health hazards associated with heat retention inside vehicles and offers urgent advice for prevention.
Why Heat Retention in Cars Is So Dangerous
When a car is parked under the sun, the temperature inside can quickly rise to 40–60°C higher than the outside temperature. In just 10 minutes, a parked car’s interior can become a life-threatening oven.
Children's bodies overheat 3 to 5 times faster than adults, and elderly people often have a reduced ability to regulate body temperature—making them especially prone to heatstroke and dehydration.
Health Risks of High Temperatures: What You Need to Know
According to Dr. Aboud, health conditions caused by excessive heat include:
- Heat Exhaustion: The body loses large amounts of fluids and salts due to excessive sweating. Symptoms include:
- General fatigue
- Dizziness
- Excessive sweating
- Nausea
- Rapid heartbeat
- Heatstroke: A life-threatening condition where the body’s temperature regulation fails, causing:
- Confusion or unconsciousness
- High body temperature (over 40°C)
- Lack of sweating
- Seizures
- Muscle Cramps: Caused by loss of sodium and dehydration
- Heat Rash: Skin irritation from excessive sweating
- Dehydration: Especially dangerous for elderly people and children
- Swelling of Extremities: Caused by fluid retention due to heat
Safety Tips to Prevent Heat-Related Illnesses
Dr. Youssef Aboud emphasizes the importance of following preventative measures, especially in summer:
Never leave children or elderly people in parked cars, even for a short time
Keep car windows slightly open or use sunshades if parking temporarily
Hydrate regularly — carry water bottles and encourage small sips frequently
Wear light, breathable clothing
Avoid outdoor activities during peak heat hours (12 PM – 4 PM)
Use AC or fans to regulate indoor temperatures
Check on elderly relatives/neighbors regularly during heatwaves
When to Seek Medical Help
If you or a loved one experiences symptoms like confusion, fainting, rapid heart rate, or persistent vomiting during hot weather, seek immediate medical attention. Heatstroke is a medical emergency and requires urgent hospital treatment.
