Priority OnDemand Medical Professional Experts Weigh in on Heat Related Illnesses

June 30, 2023

KNOXVILLE, TN (June 30, 2023)—The National Oceanic Atmospheric Administration (NOAA) recorded last summer as the third hottest summer in more than 128 years. As temperatures continue to rise in what could be another record-setting blistering season, Priority OnDemand, a national leader in EMS and medical transportation, supported by its OnDemand Visit team of healthcare professionals, weigh in on what you can do to avoid heat-related illnesses.

“Prevention is vital in helping ensure you and your family stay safe during rising temperatures this season,” said Carol Crye, MSN, FNP with OnDemand Visit. “Heat exhaustion and heat stroke are very serious medical illnesses that can quickly deteriorate a person’s health if not treated promptly and appropriately. Those working in extreme temperatures should take numerous breaks in a cooler area, replace fluids continuously, and work in the environment in shorter intervals.”

Each year more than 700 heat-related deaths occur in the United States. The most common heat-related illnesses seen by medical professionals are heat exhaustion and heat stroke. While the duration of exposure to extreme temperatures can play a crucial role in an individual’s health, even short durations could be catastrophic.

So, what are heat exhaustion and heat stroke, and what can you do to ensure yourself and your family are well protected from heat-related illnesses this season?

Heat exhaustion is the precursor to heat stroke, and while less severe, should be treated promptly as it can quickly lead to heat stroke without proper treatment. It is caused by exposure to high temperatures without adequate breaks or replacement of lost fluid.

Signs and symptoms of heat exhaustion can include:

  • Muscle cramping
  • Increased heart rate
  • Generalized weakness
  • Nausea and vomiting
  • Sweating
  • Clammy skin
  • Dizziness / fainting
  • Low urine output and/or dark, concentrated urine
  • Headaches

If left untreated, heat exhaustion can quickly turn into a heat stroke. A heat stroke is a medical emergency where the body’s core temperature rises. The hypothalamus cannot regulate the individual’s body temperature, and the body can no longer cool itself. If left untreated, the individual’s health can deteriorate, leading to seizures, coma, and death.

Signs and symptoms of a heat stroke can include:

  • Decreased level of consciousness
  • Behavioral changes such as confusion or agitation
  • Elevated heart rate
  • Excessive sweating
  • Nausea and vomiting

Differentiating between heat exhaustion and heat stroke can be challenging, so seeking medical care when in doubt is highly recommended.

Crye reminds everyone, “Don’t forget your sunscreen. Sunburned skin affects your ability to cool down, in addition to an increased risk of skin cancer.”

By staying vigilant and following these essential guidelines, individuals can safeguard themselves and their loved ones from the hazards of heat-related illnesses during what could be a sweltering summer.
