Extreme heat poses health risks to everyone — and it's a unique challenge for kids who love to be outdoors in summertime. Small children can be especially at risk in the heat, but experts say they can still play safely — if grownups follow a few guidelines.

Extreme temperatures can cause dangerous stress to the heart, kidneys and other organs, and humidity and dehydration can compound the risks. People can also sustain burns from pavement and other surfaces — including playground equipment.

Several factors put children at risk from heat, from physical characteristics to the likelihood that they're not attuned to notice signs of their own heat exhaustion. One basic rule to keep in mind is that the younger they are, the more carefully they should be monitored.
