Is Your School Taking Steps to Prevent Playground Heatstroke?

Schools are gradually returning to in-person learning thanks to the vaccination process. This is great news for children who will once again benefit from face-to-face contact with their teachers and interactions with their friends. We’re also entering the warm weather months, and the need to maintain safe social distancing practices will likely lead many schools to encourage outdoor play.

It’s important to remember that the outside temperature on a particular day must remain an important factor governing decisions about students’ ability to play outdoors. Extremely hot, sunny days place young children at serious risk of heatstroke and other heat-related illnesses. Therefore, it’s critical that your school takes the necessary steps to prevent these serious issues from developing.

When Is it Too Hot to Play Outside?

There are various factors impacting the point at which it becomes too hot for children to play outside. These include:

Keep in mind that children rarely complain when they overheat, and they typically fail to take the actions necessary to self-regulate their body temperature. In addition, children absorb more heat than adults while sweating less. These factors create a greater risk that they’ll suffer heatstroke.

It’s a good idea to review local heat advisories on hot days. This will help you make decisions that keep your students safe and reduce the likelihood of heat-related illness.

Playgrounds Radiate Heat at Extreme Levels

A research team from Columbia University measured the surface heat of playground asphalt at 134°F on a day when the air temperature was 91°F. Interestingly, the research team also found that AstroTurf gets even hotter than asphalt.

Playground equipment heats up quickly and retains this heat for prolonged periods. Not only will this increase a child’s risk of heat-related illness, but it also places them at risk of burn injuries.  In California, an ABC News team worked with a University of California San Diego professor to evaluate the temperature of standard playground equipment. They determined that playgrounds act as mini heat islands:

Common Warning Signs of Heat-Related Illness

All teachers and staff supervising outdoor activities must be educated about the warning signs of heat-related illness.

Heat Cramps

While heat cramps aren’t severe on their own, they’re typically a sign that a child is headed towards developing a more serious issue such as heat exhaustion or heatstroke. Children are particularly susceptible to heat cramps when they’re not staying hydrated. These brief, painful muscle cramps most commonly occur in the:

Heat Exhaustion

Heat exhaustion is more severe than heat cramps. It often develops when children become dehydrated while playing or exercising in a hot environment. Common symptoms include:

Heatstroke

If heat exhaustion is left untreated, it can develop into heatstroke. This is a life-threatening medical emergency that requires immediate action. During heatstroke, the child’s body generates more heat than it’s able to release, resulting in a rapid rise in core body temperature. This can lead to devastating consequences such as brain damage or death if treatment isn’t administered promptly. Common symptoms include:

If a child exhibits signs of heatstroke, call 911 immediately and request emergency assistance. While you’re waiting for help:
