An excessive heat warning is in effect in the Twin Cities, and it can take a toll on people’s health.

There are some warning signs for potential health problems. There are several types of hyperthermia, which is a heat-related illness. The most severe form is heat stroke. Someone can suffer heat stroke when the body temperature rises about 105 degrees. It can lead to brain damage if not treated. Symptoms include cramps, fatigue, dizziness, headache, nausea, vomiting and weakness.

A less severe form of hyperthermia is heat exhaustion. People suffering from this can show similar symptoms as people suffering from heat stroke. They include headache, blurred vision, nausea, thirst, profuse sweating and a moderate increase in body temperature.

The Minnesota Department of Health recommends taking frequent breaks when working or playing outdoors, wear light-colored clothes and a hat, avoid strenuous work or activities, drink plenty of water and avoid caffeinated drinks or alcoholic beverages.

If you or someone you know are showing signs of heat stroke seek medical attention immediately. Heat exhaustion can be treated by moving the person to a cool, dry place and having them lie down. You can apply cool water to their skin, ice to their head and have them drink water.
