Heat stroke is a very serious, potentially fatal condition that can cause permanent damage to the brain and other vital organs. It is characterised by a very high body temperature (above 40°C) and requires urgent medical attention. Heat stroke can cause dizziness or vertigo, along with other symptoms such as hot, flushed, dry skin, confusion, delirium, and loss of consciousness. It is important to recognise the signs and symptoms of heat-related illnesses and take immediate action to prevent heat exhaustion from progressing to heat stroke.
What You'll Learn
Heat stroke is a medical emergency
The symptoms of heat stroke include a very high body temperature (103 °F or higher), dizziness or vertigo, hot and flushed or dry skin, confusion, delirium, or loss of consciousness. Heat stroke can occur suddenly, without any prior warning signs, and any delay in seeking medical care could be fatal. Therefore, it is crucial to recognize the symptoms and act quickly.
If you or someone you know is experiencing any of the symptoms of heat stroke, it is important to call for emergency medical help immediately. While waiting for emergency services to arrive, move the person to a cool and shady area, remove any excess clothing, and try to cool them down by applying wet towels or ice packs to their skin. It is also important to ensure that they are breathing normally and, if needed, perform CPR.
To prevent heat stroke, it is crucial to stay hydrated, especially in hot weather, and to avoid strenuous activity or exercise during extreme temperatures. It is also important to wear lightweight and light-colored clothing, avoid excessive sun exposure during the hottest parts of the day, and plan ahead to keep cool and stay informed about heat-related health risks.

Heat stroke is a very serious and potentially fatal condition that requires immediate medical attention. It can cause severe damage to the brain and other vital organs. Heat stroke can occur when the core body temperature rises above 40°C and blood flow to internal organs is restricted.
If you or someone you know is experiencing any symptoms of heat stroke, it is crucial to act quickly and seek medical care immediately. Any delay in treatment could be life-threatening. Call emergency services and, while waiting for help to arrive, move the person to a cool and shady area. Remove any excess clothing, and cool the person's body temperature by applying wet sponges or ice packs to their skin, especially on the neck, groin, and armpits. If the person is conscious, encourage them to sip cool water. If they lose consciousness, position them on their side and ensure they are breathing normally.
To prevent heat stroke, it is important to stay cool, stay hydrated, and avoid overexertion in hot weather. Wear lightweight and light-colored clothing, and limit outdoor activities during the hottest parts of the day.

Heat stroke can be fatal
The early symptoms of heat stroke include behavioural changes, confusion, delirium, dizziness, weakness, agitation, slurred speech, nausea, and vomiting. In some cases, seizures and loss of sphincter control have also been reported. Sweating is generally present in exertional heat stroke, but not in classic heat stroke.
Heat stroke is particularly dangerous because it can cause multi-organ dysfunction, with typical complications including seizures, rhabdomyolysis, or kidney failure. It is important to note that heat stroke can occur without any prior signs of heat exhaustion and can strike even healthy young athletes.
The risk of heat stroke is higher in certain individuals, including older people, infants and young children, people with existing medical conditions, and those who work or exercise outdoors. Additionally, people who live in areas with hot climates or who do not have access to adequate cooling methods, such as air conditioning, are also at increased risk.
To prevent heat stroke, it is crucial to take preventive measures such as staying hydrated, avoiding excessive heat, and wearing lightweight, light-coloured, loose-fitting clothing. It is also important to monitor the colour of your urine, as darker urine can be a sign of dehydration. If you or someone you know is exhibiting symptoms of heat stroke, seek immediate medical attention and begin cooling their body temperature using the methods mentioned earlier.

Heat stroke can be preceded by heat exhaustion
Heat stroke can cause dizziness, along with other symptoms like a body temperature of 103°F or higher, hot and dry skin, confusion, delirium, and loss of consciousness. It is a medical emergency and requires immediate attention.
Heat stroke can indeed be preceded by heat exhaustion, which is a serious condition that can progress to heat stroke if not addressed. Heat exhaustion occurs when the core body temperature rises to 38-39°C. Its symptoms include muscle aches and cramps, confusion or anxiety, heavy sweating with cold and clammy skin, and a slowed or weakened heartbeat. Heat exhaustion requires immediate medical attention.
If someone is experiencing heat exhaustion, it is important to seek medical assistance and take steps to cool the person down. This includes moving them to a cool area, removing excess clothing, and applying cool water to the skin. It is also important to encourage the person to sip cool water.
Heat stroke, on the other hand, occurs when the core body temperature rises above 40°C, and blood flow to internal organs is restricted. This is a life-threatening emergency that requires urgent medical attention. While waiting for emergency medical services, move the person to a cool and shady area, remove excess clothing, and use cool water and fans to lower their body temperature. If the person is conscious and able to swallow, give them cool water to drink.
In summary, heat stroke can be preceded by heat exhaustion, and both conditions are serious and require immediate medical attention. It is important to be able to recognize the symptoms of heat-related illnesses and take appropriate steps to cool down the affected person and seek medical help.

Heat stroke can be prevented by staying hydrated
Heat stroke is a severe form of heat illness and is a life-threatening emergency. It is caused by long, extreme exposure to the sun, and it can occur suddenly without any prior symptoms of heat exhaustion. Heat stroke can be prevented by staying hydrated.
Our bodies normally cool down by sweating and radiating heat through the skin. However, in cases of extreme heat, high humidity, or vigorous activity in hot sun, this cooling system may fail, leading to a dangerous build-up of heat. Dehydration further exacerbates this issue, as the body loses water content and essential body salts, such as sodium and potassium. This can be particularly dangerous for children and the elderly, who are more susceptible to dehydration.
To prevent heat stroke, it is crucial to maintain proper hydration by drinking plenty of fluids, especially water. This is important for everyone, especially when spending extended periods outdoors or engaging in physical activities. Water is the best option, while sports drinks can also help maintain electrolyte balance. It is also recommended to limit outdoor activities, especially during the hottest parts of the day, and to wear light-coloured, lightweight clothing.
By staying hydrated and following these additional precautions, you can effectively reduce the risk of heat stroke and its associated complications, including dizziness and vertigo.
