FORT WAYNE, Ind. (WOWO): Doctors across northern Indiana are urging residents to take precautions as high temperatures and humidity continue to increase the risk of heat-related illnesses.

Medical experts say early-season heat can be especially dangerous because many people have not yet acclimated to summer conditions. As a result, individuals of all ages can be vulnerable to heat exhaustion and heat stroke, particularly those spending extended periods outdoors.

Health professionals recommend staying hydrated by drinking plenty of water throughout the day, even before feeling thirsty. Residents are also encouraged to limit strenuous outdoor activity during the hottest parts of the afternoon and seek air-conditioned environments whenever possible.

Doctors say symptoms of heat exhaustion can include heavy sweating, dizziness, nausea, weakness, headaches, and muscle cramps. If left untreated, heat exhaustion can progress to heat stroke, a medical emergency marked by a high body temperature, confusion, loss of consciousness, or the inability to cool down.

Experts advise checking on older adults, young children, and individuals with chronic health conditions, as they are often at greater risk during periods of extreme heat. Pet owners are also reminded to ensure animals have access to shade and fresh water and are never left inside parked vehicles.

With heat index values expected to remain elevated across the region, medical professionals stress that recognizing the warning signs early and taking immediate action can help prevent serious illness and save lives.
