Can Ice Pads Be Left in a Car Under Direct Sunlight?

[MilesFitz]

It is unsafe to leave ice pads in a car under direct sunlight. Here are the details: 1. Introduction to Ice Pads: Ice pads efficiently absorb body heat into the pad through polymer gel, utilizing the gel's high thermal conductivity and diffusivity. This creates an effective heat exchange and conduction process between the body and the gel pad, as well as between the gel pad and the surrounding air. Essentially, it provides a more efficient cooling pathway for the contact surface between the body and the mattress, which originally had poor heat dissipation, thereby increasing the body's cooling area and delivering comfortable and effective temperature reduction. 2. Precautions: To ensure driving safety, when purchasing an ice pad, it is crucial to check whether it has sufficient friction to prevent body sliding, which could interfere with normal driving operations. Additionally, the ice pad must be securely fastened to the seat and not merely placed loosely. Placing a cooling pad on the driver's seat can be hazardous during emergency braking, as the forward inertia may cause the body to slide off the seat. This issue is particularly common among petite female drivers who often use seat cushions to increase their seating height.
