Summer heat can quickly move from uncomfortable to dangerous, especially for employees working outdoors, in vehicles, or in warm indoor environments. Understanding the early warning signs of heat-related illness and how to respond can help prevent serious injury.
Heat Exhaustion
Heat exhaustion happens when the body overheats and cannot cool itself effectively, often due to dehydration or prolonged exposure to high temperatures.
Common symptoms include:
• Dizziness or lightheadedness
• Nausea or headache
• Heavy sweating or feeling weak
• Thirst and fatigue
If symptoms appear, move to a cooler area, rest, and hydrate immediately.
Heat Stroke
Heat stroke is a severe, life-threatening condition that occurs when the body can no longer regulate its temperature.
Common symptoms include:
• Confusion or disorientation
• Very high body temperature
• Loss of consciousness
• Rapid heartbeat or hot, dry skin
Heat stroke is a medical emergency. Call for emergency help immediately and begin cooling the person while waiting for assistance.
Tips for Staying Safe in the Heat
Simple habits can significantly reduce the risk of heat-related illness:
• Drink water regularly throughout the day, not just when thirsty
• Take frequent breaks in shaded or cooled areas
• Wear lightweight, breathable clothing when appropriate for the job
• Schedule demanding tasks during cooler parts of the day when possible
• Avoid heavy meals and alcohol before or during heat exposure
• Use cooling methods such as fans, cold compresses, or air-conditioned breaks when available
