How Heat Stroke Affects the Human Body

Heat stroke occurs when the body is unable to regulate its core temperature due to prolonged exposure to high heat and humidity. Normally, sweating and increased blood flow to the skin help cool the body. However, during heat stroke, these mechanisms fail, causing the body temperature to rise rapidly, sometimes exceeding 104°F (40°C). This extreme heat disrupts normal cellular functions and can lead to organ damage or failure if not treated promptly.

Key Physiological Changes During Heat Stroke

• Central Nervous System Dysfunction: Confusion, agitation, seizures, and loss of consciousness can occur as the brain overheats.
• Cardiovascular Strain: The heart works harder to pump blood to the skin for cooling, increasing heart rate and risk of cardiovascular collapse.
• Dehydration and Electrolyte Imbalance: Excessive sweating leads to loss of fluids and essential salts, worsening the situation.
• Organ Damage: Prolonged overheating can cause liver, kidney, and muscle tissue damage.

Common Signs and Symptoms

Symptom	Description	Severity
High Body Temperature	Core temperature above 104°F (40°C)	Critical
Altered Mental State	Confusion, agitation, slurred speech, seizures	Severe
Hot, Dry Skin	Skin may feel hot and dry or sometimes moist	Warning

Immediate Actions and Prevention

If you suspect someone is experiencing heat stroke, call emergency services right away. Move the person to a cooler environment, remove excess clothing, and cool them rapidly with cold water, fans, or ice packs. Do not give fluids if the person is unconscious. Early intervention can save lives and prevent long-term complications.

Prevention is key. Stay hydrated, wear light clothing, avoid strenuous activities during peak heat, and never leave anyone in a parked car. For more detailed prevention tips, read the full Shopify article or view the Google Doc version.
