Are Heat Exhaustion and Heat Stroke the Same?

During the summer months, soaring temperatures and intense sunlight can pose health risks. It’s essential to be mindful of the dangers of sun overexposure while enjoying outdoor activities.

Heat exhaustion and heat stroke are serious conditions that require prompt attention if you experience any symptoms. Untreated heat stroke can actually be fatal, so learning the signs and symptoms is crucial.

Keep reading as our AFC Urgent Care Louisville team talks about the difference between heat exhaustion and heat stroke.

Understanding Heat Exhaustion

Heat exhaustion occurs when the body overheats and becomes dehydrated due to prolonged exposure to high temperatures and humidity. Although less severe than heat stroke, untreated heat exhaustion can escalate to a more critical condition. Anyone can be susceptible to heat exhaustion, but it’s particularly common among those who spend extended time outdoors, athletes or individuals unaccustomed to heat.

To prevent heat exhaustion, stay hydrated, take breaks in shaded areas and avoid strenuous activities during peak sun exposure, which is between 10 a.m. and 4 p.m. Don’t forget to apply sunscreen with an SPF of at least 30 for added skin protection. Wear loose-fitting, light clothing and keep a close eye on how you feel. If you notice yourself developing any of the symptoms below, head inside or find the shade immediately.

Symptoms of Heat Exhaustion

  • Profuse sweating
  • Weakness
  • Dizziness
  • Headaches
  • Nausea

Understanding Heat Stroke

Heat stroke is a severe medical emergency occurring when the body’s internal temperature surpasses 104°F due to prolonged exposure to high heat and humidity. The body loses its ability to regulate temperature, causing a person to stop sweating. Heat stroke can cause damage to vital organs and be fatal if not treated promptly.

Infants, older adults and those with chronic health conditions are most vulnerable to heat stroke. Preventive measures include staying hydrated, wearing lightweight clothing, taking frequent breaks in shaded areas and avoiding outdoor activities during peak heat hours. If you notice any of the below symptoms in yourself or in a loved one, call 911 and go indoors.
