SUNDAY, June 29, 2014 (HealthDay News) -- Parents need to be aware that hot weather can pose a serious threat to children and must take steps to protect their youngsters, an expert says.
In extremely hot weather, children's play time should be restricted to early morning or late afternoon, Dr. Eric Kirkendall from Cincinnati Children's Hospital Medical Center recommended in a medical center news release.
Parents also need to monitor children's physical activity to make sure they don't overexert themselves.
"Keep them well-hydrated with water, and take frequent breaks to allow them to come inside and cool off," Kirkendall said.
Hot weather puts children at risk for three types of problems, he noted. "Heat stroke, heat exhaustion and heat cramps are reactions caused by exposure to high temperatures combined with high humidity," Kirkendall said. "The most serious of these is heat stroke."
Heat cramps typically occur in the abdomen and legs, especially the calf or thigh muscles. There is no fever. Symptoms of heat exhaustion include pale skin, profuse sweating, nausea, dizziness, fainting and weakness. Children with heat exhaustion require medical attention.
Symptoms of heat stroke include hot flushed skin, high fever (over 104 degrees F), confusion and other altered mental states, and seizures. This is a life-threatening emergency and 911 needs to be called immediately, Kirkendall said.
Keep the child as cool as possible while waiting for emergency crews to arrive. For example: move the child to a cool, shady place or an air-conditioned room; fan the child; sponge the child's entire body with cool water. If the cool water makes the child shiver, stop.
If the child is awake, give him or her as much cold water as they can drink. Don't use fever medicines, because they do nothing to treat heat stroke, Kirkendall said.
