With summer upon us, it’s important to remember that young children are more susceptible to dehydration than adults. Dr. Michael Watts with Lee’s Summit Medical Center reminds parents that once a child becomes dehydrated, he or she is vulnerable to more serious heat-related illnesses such as heat cramps, heat exhaustion or heatstroke. He advises drinking plenty of fluids, taking frequent breaks and watching for early symptoms of dehydration such as thirst, fatigue and nausea.
