In anticipation of temperatures 95 degrees and higher, a number of southwest Ohio cities are issuing heat advisories. According to the National Weather Service, temperatures in Portsmouth are expected to be skyrocket over the weekend, reaching a high of 94 degrees today and 89 degrees on Sunday.

Despite calls for high temperatures, the Portsmouth Health Department does not anticipate issuing a heat advisory.

During periods of extreme heat, it is important to take steps to avoid heat exhaustion and heatstroke.

Symptoms of heat exhaustion, which occurs when the body is dehydrated, include headaches, nausea, dizziness, cool and clammy skin, pale face, cramps, weakness, and profuse perspiration. It can be treated by moving to a cool area and drinking water.

Heatstroke occurs when the body overheats but perspiration cannot occur, and can sometimes be fatal. Those experiencing symptoms of heatstroke, which include chills, a rapid pulse and body temperature above 101 degrees, should immediately be moved out of the heat and wrapped in a cool, wet sheet.
