Extreme Heat

Orange County regularly experiences heat waves, which can be particularly dangerous for children, seniors, residents with cardiovascular disease or those taking psychotropic and other medications.

Even in modern times, heat waves can cause serious causalities. A heat wave's duration plays an important role in how people are affected. Studies show that a significant rise in heat-related illnesses occurs when excessive heat lasts for more than two days. Spending even two hours per day in air-conditioned spaces can significantly reduce the number of heat-related illnesses.
