In this video Dr O'Donovan explains key things you need to know about heatstroke.

What is Heat Stroke?

Heat stroke is a serious medical emergency where the body's temperature rises uncontrollably due to overheating, and the body's cooling mechanisms fail. It's characterized by a core body temperature of 40°C (104°F) or higher, and it can lead to organ damage and even death if not treated promptly.

Key Characteristics of Heat stroke:
1. High Body Temperature: Core temperature exceeding 40°C (104°F) is a hallmark of heat stroke.
2. Central Nervous System Dysfunction: Confusion, seizures, loss of consciousness, and other neurological symptoms can occur.
3. Failure of Cooling Mechanisms: The body's ability to sweat and regulate temperature is impaired.
4. Potential for Organ Damage: If not treated quickly, heat stroke can damage the brain, heart, kidneys, and muscles.

Emergency Condition: Heat stroke requires immediate medical attention.

Causes:
Prolonged Exposure to High Heat: Spending extended time in hot environments, especially without proper hydration and rest, can lead to heat stroke.
Exertion: Strenuous physical activity in hot weather can also trigger heat stroke.
Underlying Health Conditions: Certain health conditions and medications can increase susceptibility.

Symptoms:
High Body Temperature: Fever, often above 40°C.
Altered Mental State: Confusion, disorientation, irritability, seizures, loss of consciousness.
Skin Changes: Hot, flushed, and dry skin (or in some cases, excessive sweating).
Rapid Heartbeat and Breathing: Heart rate and breathing can become very fast.
Nausea and Vomiting
Headache and Dizziness
Weakness and Muscle Cramps:

First Aid (Immediate Actions):
1. Call for Emergency Assistance: Dial 999 (or your local emergency number) immediately.
2. Move to a Cool Environment: Get the person out of direct sunlight and into a cool place.
3. Cool the Person Down:
Remove excess clothing.
Apply cool, wet cloths or towels to the skin, or fan the person.
If available, immerse the person in cool (not cold) water or a cool shower.
Apply ice packs to the neck, armpits, and groin.
Monitor and Support: Stay with the person, monitor their condition, and provide support until help arrives.

Heat stroke can develop rapidly and is a serious medical emergency. Do not delay seeking medical help.
