INDIANAPOLIS — We're adding moisture to the air today as the wind direction shifts from the southwest. You'll feel this as dew point temperatures rise. It's a combination of the air temperature and dew point that gives us a "heat index." We use this to see how the air around us impacts how well our bodies deal with heat.
With heat indices topping out between 95-100 today, it becomes more difficult for our bodies to cool.
When the moisture content of the air is low, it allows our sweat to evaporate easier and our body removes heat quicker. When the moisture is high outside, this limits evaporation and slows down our body's cooling process causing increased risk of heat-related illnesses.
On a day like today, it is important to stay well hydrated, take frequent breaks, and of course remember to never leave the pets or kids inside a parked vehicle.
