Protecting children from the dangers of hot cars is an increasingly urgent issue, especially during the warmer months. Even when temperatures don’t seem extreme, the inside of a car can heat up quickly – often reaching deadly temperatures in mere minutes.
It’s essential to understand how rapidly heat can affect a child’s body, why young children are particularly vulnerable, and what practical steps you can take to prevent tragic outcomes.
Understanding the Risks: Why Heat Affects Children Differently
Unlike adults, young children’s bodies are less efficient at regulating temperature. Children’s bodies can heat up three to five times faster than adults due to their larger body surface relative to their size and other physiological factors.
When a child’s body temperature reaches 40°C, heat stroke begins, affecting the body’s ability to cool down. At 41.6°C, this can lead to irreversible organ damage and even death. Tragically, even a cracked window does not lower the temperature enough to prevent heat stroke in a parked car.
The Rising Need for Caution: Statistics on Hot Car Incidents
While summer is the most dangerous season, heat-related incidents can occur year-round. Many parents and caregivers mistakenly believe they would never forget their child in the car, yet almost half of hot car deaths happen because a child is forgotten by a distracted or stressed adult. A significant percentage of cases involve children getting into cars on their own and becoming trapped.
Implementing a few simple, proactive steps can make a life-saving difference.
Here are ten important tips for keeping children safe:
1. Never leave a child unattended in the car
Even if you plan to be gone for just a few minutes, never leave a child alone in the car. Short stops often take longer than anticipated, and it only takes 10-15 minutes for a car’s interior to reach life-threatening temperatures on a hot day.
2. Use curbside pickup or delivery services
When possible, utilise grocery delivery or curbside pickup services, especially in hot weather. These services help you avoid leaving children in a parked car and minimise the time you need to be out in high temperatures.
3. Always Check the Back Seat Before Leaving the Car
Place essential items such as your wallet, purse or cell phone in the back seat as a reminder to check for children before locking the vehicle. Many parents also use apps and car seat alarms designed to alert drivers of a child in the back seat.
4. Keep Car Keys Out of Reach
Prevent children from playing with car keys. In some tragic cases, children have locked themselves in cars while playing. Always keep keys in a safe, inaccessible location.
5. Teach Kids to Signal for Help
Instruct older children to honk the horn if they ever find themselves trapped inside a car. Teaching them to use this signal for help can bring immediate attention if they are accidentally left in or become stuck in a vehicle.

6. Use Technology as a Reminder
Set up alarms or reminders on your smartphone to double-check the back seat before you leave your car. Some parents schedule phone reminders timed with typical arrival times for added peace of mind.
7. Monitor the Volume in Your Car
Keeping the car stereo at a reasonable volume can help you stay aware of any sounds from the back seat. It’s easier to hear if a child is in distress when background noise is kept to a minimum.
8. Make ‘Look Before You Lock’ a Habit
Train yourself to always check the car’s interior before locking up, even if you’re certain no child is inside. This habit can help you avoid any potential lapses in awareness, especially on busy
or stressful days.
9. Use a Mirror Attachment for Better Visibility
Installing a mirror in the back seat that reflects the child’s car seat can be invaluable. This allows you to check on your child with a simple glance while driving, making it less likely that they’ll
be forgotten when you leave the car.
10. Spread Awareness and Encourage Others to Stay Vigilant
Educate friends, family and caregivers about the dangers of leaving children in hot cars. Encourage them to adopt similar precautions and stay alert to potential risks, particularly when transporting your child.
Additional Measures: New Technology and Innovations
In recent years, automakers and technology companies have introduced innovations to help reduce hot car incidents. For example, many newer car models come equipped with rear-seat reminder systems that activate if a back door is opened at the start of the journey.
Other products, like smart car seats, are designed to sound alarms if a child is left in the vehicle. Some child safety organisations also offer clip-on alarms that attach to a child’s car seat belt, which can sound alerts on a parent’s phone if the child is left unattended.
A Final Note on Child Safety in Hot Weather
Being proactive and informed can prevent tragedy and protect the well-being of children in your care. Hot car deaths are entirely preventable, but vigilance and precaution are required. By building safe routines, utilising technology and educating others, you can help ensure that every child arrives safely at their destination. Remember, taking even a few seconds to check the back seat can save a life.
No errand, no matter how important, justifies leaving a child in a parked car. Staying alert, prepared and informed makes all the difference in keeping children safe in any weather.
