Extreme Heat Brings Danger
Placeholder Image
With nearly a week of 100-plus degree days behind us but more to come, local officials are urging continued extreme caution.

Temperatures this hot can cause undue stress on the human body, as well as pets and livestock. A prolonged period of hot temperatures may lead to the serious medical conditions of heat stroke or heat exhaustion. Public health officials urge the public to be prepared and take precautions to prevent heat stress. San Joaquin County Health Officer, Dr. Karen Furst emphasizes, "Heat stress can result in heat stroke, heat exhaustion, heat cramps, or heat rashes, so it is also important to be aware of dangerous heat related symptoms."

Dr. Cora Hoover, Assistant Health Officer of San Joaquin County adds, "Groups especially at risk for heat stress are the elderly, adults with disabilities, chronically ill, children under 4 years old and anyone who works or exercises vigorously outdoors." Some health conditions such as obesity, fever, dehydration, heart disease, poor circulation, sunburn and drug and alcohol use can make it harder for the body to stay cool in hot weather.
