Why is it so dangerous to leave a child alone in a car? Because of biology, anatomy, thermodynamics.
Let’s talk a little about Infant and Child Anatomy:
- Infants and children do not temperature regulate well. They have too much surface area for their body mass, meaning they lose heat too quickly because they don’t have enough mass to contain the heat.
- Because they lose heat quickly, they generate it faster, 3 to 5 times faster than adults. For example, when you’re holding a baby for a while and then hand them off to someone else, you feel chilled. This is because the baby was generating so much heat that our temperature drops. (We are the best thermo-regulators that a baby can have.)
Next, let’s set the stage and look at what happens in a car:
