Heat, Humans, and Our River

By Nancy Rudner

This may be the hottest summer on record.  Not only are the days warmer, but the evenings are warmer too.  In 1925, 100 years ago, Florida had 80 days with temperatures of 90°F or more. Last year, in 2025, we had 139 days as hot or hotter.

What does the heat do to humans, wildlife, and our rivers?  The warmer climate is altering our ecosystem, changing which insects, plants, and yes, snakes and other such critters, live in the Wekiva River Basin.  Pythons are migrating north from the Everglades. Tick-borne diseases are spreading into new territories.  The increased heat may contribute to more evaporation and, when coupled with less rain, lower water levels.

Humans struggle in the intense heat and are more at risk for heat illness.  If you feel dizzy, weak, nauseous, or have a headache or excessive sweating, you need to get out of the heat. If you stop sweating, your body may be experiencing a heat stroke - a serious emergency requiring immediate attention.  Stay hydrated as much as possible. Avoid high sugar drinks (like sodas) and energy drinks. Over time, humans exposed to high temperatures and dehydration are more likely to develop kidney disease.  Keep drinking water! Your pee should be very pale yellow. The classic recommendations are to stay hydrated, take frequent breaks, and rest frequently when you are outside in the heat.
