Heat Safety—Your Must-Do List
When the air feels like soup, staying safe isn’t optional—it’s essential:
-
Hydrate constantly: Water is your best friend. Skip sugary or alcoholic drinks—they can dehydrate you even more.
-
Time your outings: Head outside early morning or evening if possible. Noon to late afternoon is furnace‐mode.
-
Protect your skin: Always slap on sunscreen, and bring sunglasses and a hat wherever you go.
-
Know the signs: Warning flags like dizziness, nausea, or rash could hint at heat exhaustion. Don’t wait—find shade or an AC spot and hydrate thoroughly.
-
Look out for neighbors: Folks without air conditioning or the elderly can be especially vulnerable in these conditions.
Why Louisville Feels Especially Sticky
Louisville’s geography doesn’t help. Our city sits in an Ohio River floodplain, nestled between two plateaus. That positioning, along with limited tree canopy—especially downtown—traps heat and pollutants. The urban heat island effect here is especially strong, with temperatures often soaring 1.67°F per decade above rural zones—nearly double what Phoenix sees.
