Heat stress and stroke are one of the most common workplace injuries in warmer climates. In 2015, exposure to environmental heat led to 37 work-related deaths and 2,830 nonfatal occupational injuries and illnesses involving days away from work. 33 of the 37 fatalities caused by exposure to heat occurred in the summer months of June through September.

What Are The Signs and Symptoms of Heat Stress?

The risk of heat stress and stroke dramatically increases when the heat index climbs to 90 degrees or more, but understanding the signs and symptoms can limit the risks and effects.

Common Signs of Heat Stress and Stroke:

  • A throbbing headache
  • Dizziness, light-headedness or fainting
  • Lack of sweating, despite the heat
  • Red, hot, and dry skin
  • Muscle weakness or cramps
  • Nausea and vomiting
  • Rapid heartbeat or breathing
  • Behavioral changes such as confusion, disorientation, or staggering
  • Seizures

Heat stroke is an emergency situation in which the body loses its ability to cool itself.

What To Do For Heat Stress or Stroke

If you or someone else starts to experience symptoms of heat stress or stroke, call 911. While waiting for EMS to arrive, follow these steps:

  1. Get to a shaded area immediately
  2. Loosen clothing or remove as much clothing as possible
  3. Cool the victim rapidly using whatever method possible. This may include putting them in a tub of cool water or cold shower; spraying them down with cool water from a garden hose, sponging them with cool water, or if the humidity is low; wrapping them in a cool, wet sheet and fanning him or her vigorously
  4. Put ice packs or cold compresses under their arms, on their groin area, and behind their neck

If someone is experiencing a heat stroke, sometimes their muscles will begin to twitch uncontrollably. If this happens, keep the victim from injuring themselves, but do not give them any fluids. If there is vomiting, make sure the airway remains open by turning the victim on his or her side.

Heat-related symptoms and illnesses are nothing to take lightly. Use the above information to help keep each other safe!
