Hot Cars and Unforeseen Consequences: Dangers of Leaving Children Unattended in Vehicles During Extreme Heat

In extreme heat, a toddler trapped in a closed vehicle can experience excessive sweating, which can lead to dehydration and a drop in blood pressure. This drop in blood pressure can cause a lack of oxygen supply to sensitive organs like the brain, resulting in loss of consciousness, convulsions, cardiac arrhythmias, and even severe brain damage. Dehydration processes can also cause irreversible damage to the kidneys, sometimes requiring dialysis or a kidney transplant.

When left unattended in a hot vehicle for just 30 minutes, a baby can suffer from burns on its skin that can be painful and lead to confusion and an accelerated heart rate. These burns can disrupt the body’s ability to meet oxygen demands and add to the baby’s distress, leading to additional fluid loss and disruption in salt balance. The intense heat directly affects brain function, leading to the expansion of blood vessels that may rupture and cause severe bleeding. Salt disturbances can result in convulsions that further reduce oxygen supply to the brain.

The body’s systems can also disrupt kidney function due to intense heat, salt loss, and decreased blood volume. When left unattended for too long, these conditions can eventually lead to kidney failure. Furthermore, when a baby loses 15% of its body fluids through excessive sweating or other means, it almost always ends in death. It is crucial for parents or caregivers never leave their child unattended in a vehicle during hot weather to prevent these severe consequences.
