☀️ Signs of Heat Exhaustion vs Heatstroke
With high temperatures affecting many parts of France, it's important to know the difference between heat exhaustion and heatstroke.
Both are caused by the body struggling to cope with heat, but heatstroke is a medical emergency.
🌡️ Heat Exhaustion
Heat exhaustion can develop after prolonged exposure to high temperatures or dehydration.
Common signs include:
• Heavy sweating
• Dizziness or feeling faint
• Headache
• Weakness or fatigue
• Nausea
• Muscle cramps
• Cool, pale, or clammy skin
What To Do
• Move to a cooler place
• Encourage small amounts of cool water if the person is fully conscious and able to drink
• Loosen or remove excess clothing
• Cool the skin with water, damp cloths, or a fan
• Rest
If symptoms worsen or do not improve, seek medical advice.
🚨 Heatstroke (Medical Emergency)
Heatstroke occurs when the body's temperature rises to dangerous levels and it can no longer cool itself effectively.
Warning signs may include:
• Confusion or unusual behaviour
• Loss of consciousness
• Seizures
• Very high body temperature
• Hot, red skin (which may be dry or sweaty)
• Difficulty responding normally
What To Do
Call 15 (SAMU) immediately.
While waiting for help:
• Move the person to a cool place
• Cool them with water, wet towels, or fans if possible
• Do not give fluids to someone who is unconscious or unable to swallow safely
• Do not delay seeking emergency assistance
💡 A Simple Rule
If someone is confused, unconscious, having seizures, or appears seriously unwell during a heatwave:
Treat it as a medical emergency and call 15 immediately.
Save this post — knowing the difference could help protect someone during a canicule.
