Sunstroke, also known as heatstroke, is a severe heat illness that occurs when the body's core temperature rises above 104 degrees Fahrenheit (40 degrees Celsius). It is a life-threatening condition that requires immediate medical attention. Sunstroke is typically the result of prolonged exposure to high temperatures, often in combination with dehydration, leading to a failure of the body's temperature control system. The early symptoms of sunstroke include behavioural changes, confusion, dizziness, nausea, and vomiting. If left untreated, sunstroke can cause organ failure, coma, and even death.

Sun stroke is a life-threatening condition that can lead to organ failure and death
Sun stroke, or heat stroke, is a life-threatening condition that requires immediate medical attention. It occurs when the body's core temperature rises above 104°F (40°C), and is usually the result of overexertion in hot, humid conditions. Sun stroke can also be caused by prolonged exposure to high temperatures, often in combination with dehydration, which causes the body's temperature control system to fail.
The high body temperature associated with sun stroke causes profound changes in brain function, including confusion, disorientation, seizures, and loss of consciousness. It also causes profound cardiovascular side effects, such as low blood pressure and an elevated heart rate. These symptoms can lead to organ failure and death if not treated promptly.
Organ failure occurs when the brain swells, causing individual brain cells to stop functioning and preventing them from communicating with the rest of the body. This, in turn, causes the organs to stop receiving the appropriate information from the brain and begin to shut down. Inflammation can also affect brain and nerve function, further damaging the organs.
The risk of organ failure and death from sun stroke is heightened by the body's inability to cool itself down. The high temperature causes blood vessels to dilate and blood pressure to drop, affecting circulation and the transportation of oxygen and nutrients to the organs. This can lead to blood clots and a lack of oxygen to the brain, resulting in a coma and convulsions.
The longer the body is left untreated at high temperatures, the greater the risk of organ failure and death. Immediate medical treatment is required to lower the body temperature and prevent permanent damage or death.

It is caused by prolonged exposure to high temperatures and/or physical exertion
Sunstroke, or heatstroke, is a severe heat illness that results from prolonged exposure to high temperatures and/or physical exertion. It is a life-threatening condition that requires immediate medical attention.
The human body is extremely sensitive to changes in its internal temperature. Usually, the body works to maintain an internal temperature of around 98.6 degrees Fahrenheit. When exposed to high temperatures, the body responds by sweating to cool down, and by pumping blood to the skin's surface and extremities to release internal heat. However, these responses are taxing on the body and can lead to heat-related illnesses such as heat cramps, heat exhaustion, and, in the most severe cases, heatstroke.
Heatstroke occurs when the body's temperature control system fails due to prolonged exposure to high temperatures and/or physical exertion, causing the body to lose control of its internal temperature. This can happen gradually over several hours or days, or it can come on suddenly within 10-15 minutes. The core body temperature rises above 104 degrees Fahrenheit, leading to serious complications involving the central nervous system.
Exertional heatstroke is typically caused by strenuous exercise or physical labour in hot and humid conditions. Certain occupations, such as athletes, outdoor labourers, military personnel, and first responders, are at a higher risk of developing exertional heatstroke. It is important to note that humidity reduces the body's ability to cool itself through perspiration and evaporation, further increasing the risk of heatstroke.
Non-exertional heatstroke, also known as classic heatstroke, can occur in individuals with certain health conditions or genetic predispositions, particularly children and the elderly. It tends to develop over several days and can be life-threatening if left untreated.
The early symptoms of heatstroke include behavioural changes, confusion, disorientation, dizziness, weakness, agitation, slurred speech, nausea, and vomiting. As heatstroke progresses, more severe symptoms can occur, including seizures, sphincter incontinence, and excessive sweating. Without prompt and adequate treatment, heatstroke can lead to vital organ damage, unconsciousness, and even organ failure, resulting in death.

Symptoms include confusion, seizures, red skin, dizziness, and nausea
Sunstroke, or heatstroke, is a severe form of heat injury and is considered a medical emergency. It is defined by a body temperature of 104°F (40°C) and is usually the result of overexertion in hot, humid conditions. It can also be caused by prolonged exposure to high temperatures, often in combination with dehydration.
Heatstroke can lead to brain damage, organ failure, or death, so it is important to act quickly if you suspect someone is suffering from this condition. While waiting for emergency services, move the person to a cool, shady area and remove any unnecessary clothing. Try to cool their body temperature to 101-102°F by applying ice packs to the neck, groin, and armpits, or immersing them in cool water.
Heatstroke can cause a variety of symptoms, including confusion, seizures, red skin, dizziness, and nausea. Confusion and disorientation are behavioural changes that can indicate heatstroke and may be accompanied by staggering. Seizures are also a common symptom, and medication to prevent them may be administered in hospital.
Red, hot, and dry skin is another symptom of heatstroke, indicating that the body's temperature control system is failing. This can be accompanied by dizziness and light-headedness, as well as a rapid heartbeat and shallow breathing. These symptoms can be indicative of heatstroke and require immediate medical attention.

Treatment involves rapid physical cooling and supportive care
Sunstroke, or heatstroke, is a life-threatening condition that requires immediate medical attention. While waiting for emergency services, it is important to begin cooling the person down as rapidly as possible. This involves removing them from direct sunlight and applying cooling methods to reduce their body temperature.
Firstly, move the person to a cool, shady area, preferably with air conditioning. Remove any unnecessary clothing, especially if it is heavy or tight-fitting. Get the person into a cool bath, shower, or stream if possible, but avoid very cold temperatures and ice, especially for older people, young children, or those with chronic illnesses. Do not submerge unconscious people in water. Instead, apply cool, wet rags to the back of the neck, groin, and armpits. Misting the person with water and fanning them will promote evaporative cooling, which is faster than simply wetting the skin.
It is also important to rehydrate the person and replenish their electrolytes. Encourage them to sip on sports drinks or salted water (1 teaspoon of salt per quart of water). Do not give anything to drink if the person is vomiting or unconscious, as this could cause choking.

Prevention includes staying hydrated, wearing light clothing, and avoiding excessive heat
Sunstroke, or heatstroke, is a severe and life-threatening condition that occurs when the body is unable to regulate its temperature, causing it to rise above 104°F (40°C). It is often the result of overexertion in hot and humid conditions, and it can lead to organ failure, coma, or even death. Therefore, prevention is crucial and includes staying hydrated, wearing light clothing, and avoiding excessive heat.
Staying hydrated is essential for preventing sunstroke. Dehydration occurs when the body loses more fluids than it takes in, and it can be exacerbated by excessive sweating, lack of water intake, fever, or certain medications. To stay hydrated, it is recommended to drink plenty of water throughout the day, and incorporating water-rich foods or electrolytic drinks can also help. Avoiding caffeine and alcohol is important as they contribute to dehydration. Monitoring urine colour is a good indicator of hydration levels, with darker urine indicating dehydration.
Wearing light clothing is another key aspect of sunstroke prevention. Lightweight, light-coloured, and loose-fitting clothing helps keep the body cool by allowing heat to escape and reducing sweating. Dark-coloured clothing absorbs sunlight, increasing body temperature, while tight or heavy clothing can hinder the body's ability to cool down.
Avoiding excessive heat is crucial to preventing sunstroke. This includes seeking shade, wearing sunscreen, and limiting direct sun exposure, especially during the hottest parts of the day. Staying in air-conditioned or well-ventilated areas is important, as is gradually acclimating to warmer temperatures if you need to be in hot conditions. Strenuous physical activity in hot and humid weather should be avoided, and it is essential to give yourself breaks from direct sunlight.
By staying hydrated, wearing light clothing, and avoiding excessive heat, you can effectively prevent sunstroke and reduce the risk of its life-threatening complications.
