As the summer weather becomes hot and humid, the South Bend Fire Department is encouraging area residents to watch out for signs of weather-related illness.

People who spend a lot of time outside during the summer can be at risk for heat exhaustion and heat stroke, especially during exercise or other physical activity.

Signs of heat exhaustion include: dizziness, headache, sweaty skin, fast heartbeat, nausea, vomiting, weakness and cramps.

Signs of heat stroke include red, hot and dry skin, fever, confusion, fainting and convulsions.

To avoid getting sick, people should drink water, replenish minerals like salt and alternate between being outside and being inside, according to MedlinePlus.

Anyone who experiences symptoms of heat sickness should be moved inside. If symptoms persist, go to the emergency room or call 911.
