General & First Aid
Heat Stroke
A life-threatening emergency in which body temperature rises to 105°F or higher and the cooling mechanisms fail — requiring immediate emergency cooling to prevent brain damage and death.
Also known as: Sunstroke, Heat Hyperpyrexia, Hyperthermia
📝 At a glance
Likely root causes: Exposure to extreme heat combined with high humidity and exertion; Failure of the body's heat-dissipation mechanisms; Dehydration reduces the ability to sweat.
First thing to try: BEGIN COOLING IMMEDIATELY — do NOT wait
See a doctor if: This IS a medical emergency.
🔎 Start with the cause
Lasting relief rarely comes from covering a symptom. First find what is feeding the problem, change what you can, and then help the body do what it was designed to do — heal.
Likely root causes
- Exposure to extreme heat combined with high humidity and exertion
- Failure of the body's heat-dissipation mechanisms
- Dehydration reduces the ability to sweat
- Poor physical conditioning and nutritional deficiencies increase risk
- Working or exercising in direct sun during peak heat hours
- Hot, poorly ventilated environments
Change what you can
- BEGIN COOLING IMMEDIATELY — do NOT wait
- If near a hospital: wrap the person in an ice-cold sheet and rush to the hospital; apply more ice water as you travel
- Check temperature every 5–10 minutes; STOP cooling if temperature drops below 101°F
- If NOT near a hospital: place in an ice-cold bath and use fans to aid cooling; rub arms, legs, hands, and feet to increase circulation
- If no ice bath available: use cold stream or lake until medical help arrives
- Dr. Kellogg's sunstroke protocol: from a height, pour water (60°F or less) onto the person while two people rub vigorously; give special attention to the spine; continue until temperature falls to 101°F
- After temperature returns to normal: daily graduated cold applications (Tonic Frictions) to rebuild the body

Aggressive cooling while awaiting the ambulance is the priority in heat stroke.
How to do it ▾
Why it works: In heat stroke the body can no longer shed heat and its core temperature climbs dangerously. Wetting the skin and moving air over it, plus cold packs at the neck, armpits, and groin, pull heat out quickly and buy time until medical help arrives.
- Call emergency services immediately - heat stroke is life-threatening.
- Move the person to shade or indoors and remove extra clothing.
- Cool them any way you can: cool water over the skin, wet cloths, and fanning.
- Place cold packs on the neck, armpits, and groin where large blood vessels run.
- If they are fully alert and able to swallow, give small sips of cool water; raise the feet about 12 inches.
Until temperature drops and help arrives · Continuously during the emergency
Caution: This is an emergency - never skip calling for help to try to manage it at home. Do not give fever medicines like aspirin or acetaminophen; they do not help heat stroke and can harm. Do not give fluids to anyone confused, vomiting, or not fully awake - it can choke them.
When to get help: Any suspected heat stroke - high body temperature with confusion, fainting, seizures, hot skin, or a rapid pulse - needs emergency services at once.

“Disease is an effort of nature to free the system from conditions that result from a violation of the laws of health... In case of sickness 1cause should be ascertained, 2go to work intelligently to remove the disease. 3Unhealthful conditions should be changed, 4wrong habits corrected. 5Then nature is to be assisted in her effort 6to expel impurities and 7to re-establish right conditions in the system.”
🌿 Overview
Heat stroke is one of the most dangerous medical emergencies. Unlike heat exhaustion (where sweating continues), in heat stroke sweating is dramatically reduced or absent. The brain begins to overheat. Without immediate treatment, convulsions, permanent brain damage, and death can follow rapidly. Begin cooling immediately — do not wait for symptoms to develop further.
Heat stroke is a life-threatening emergency in which the body overheats — to around 104°F (40°C) or higher — and its cooling system fails, so it can no longer shed heat. Warning signs include hot skin (often dry, as sweating stops), a pounding headache, confusion, rapid pulse, and collapse, and it can quickly damage the brain and organs.
This demands immediate action: call emergency services and cool the person as fast as possible — move to shade or indoors, remove excess clothing, and apply cool water and fanning or cold packs while waiting for help. It is not a situation for cautious home care. The natural emphasis is prevention: staying well hydrated, avoiding exertion in extreme heat, resting in cool shade, and watching especially over children, the elderly, and outdoor workers, who are most at risk.
Common signs
- Body temperature of 105°F (40.5°C) or higher
- Sweating dramatically reduced or absent
- Throbbing headache with tingling and numbness
- Confusion of mind and delirium
- Rapid pulse and faster breathing
- Rising blood pressure
- Can progress rapidly to convulsions, coma, permanent brain damage, and death

Cool fluids help if the person is alert, but heat stroke (confusion, no sweating, very high temperature) is an emergency — call 911.1000
Heat stroke is a life-threatening emergency — call 911 and cool the person fast with cold packs to the neck, armpits, and groin while waiting.940
If conscious and able to swallow, small sips of cool water help — but the priority is rapid cooling and calling 911.940

🍽️ Eating to help
Food is one of the gentlest medicines — small, steady changes help most.
Favor these
- Cold water drinking to restore hydration
- Electrolytes after recovery
- Light, easily digested foods during recovery
Go easy on
- Alcohol — impairs heat regulation
- Caffeine — diuretic, worsens dehydration
PREVENTION: Drink water before and during heat exposure. Wear light, loose clothing. Avoid direct sun during peak hours (10 am–3 pm). Know the difference between heat exhaustion (person still sweating) and heat stroke (not sweating, temperature over 105°F).
⚖️ Good to know
- This is a medical emergency — call 911 immediately
- Do NOT put someone with heat stroke in a hot car
- Do NOT delay cooling to wait for medical help — begin cooling immediately
- Stop cooling treatment when temperature drops to 101°F — overcooling can cause shock
- Distinguish from heat exhaustion: in heat stroke sweating is absent or minimal; in heat exhaustion sweating is heavy
