Denton summers regularly push past 100°F, and long stretches of extreme heat put everyone at risk — outdoor workers, student athletes, kids at the park, and older adults. Heat-related illness is common across North Texas every summer, and knowing the warning signs matters.
What heat exhaustion looks like
Heat exhaustion happens when the body loses too much water and salt through heavy sweating. People often notice heavy sweating, weakness or fatigue, cool or clammy skin, nausea, headache, dizziness, and muscle cramps. It can come on gradually during a hot afternoon outdoors.
Heat exhaustion vs. heat stroke
Heat stroke is the more dangerous stage. Warning signs include hot, red, or dry skin, a rapid pulse, confusion, fainting, or a body temperature that feels very high. Heat stroke is a medical emergency — call 911 right away if these signs appear. Do not wait to see if symptoms improve on their own.
What a clinic visit may involve
For milder heat-related symptoms, a clinic visit may involve an evaluation of vital signs, a discussion of what happened, and monitoring to make sure symptoms are resolving. A provider can also help determine whether symptoms point to something else entirely.
