Heat Stroke: Can It Cause Shaking?

Heat stroke is a severe heat-related illness that can be life-threatening. It occurs when the body is unable to regulate its internal temperature, typically due to a combination of physical exertion and hot, humid conditions. This can lead to a range of symptoms, including confusion, seizures, and loss of consciousness. While heat stroke typically results in an elevated body temperature, can it cause shaking or chills?

Heat stroke is a medical emergency

The hallmark symptom of heat stroke is a core body temperature above 104°F (40°C). However, fainting may be the first sign, along with other symptoms such as dizziness, light-headedness, red and dry skin, muscle weakness or cramps, and a rapid heartbeat. If you or someone else is exhibiting these symptoms, it is crucial to act quickly and seek medical help.

To provide initial assistance to someone experiencing heat stroke, move them to a cool and shaded area, preferably with air conditioning. Remove any unnecessary clothing to help lower their body temperature. It is important to initiate first aid cooling strategies, such as fanning the person while wetting their skin with water or applying ice packs to their armpits, groin, neck, and back. These areas are rich in blood vessels close to the skin, aiding in reducing body temperature.

While waiting for emergency services to arrive, monitor the person's body temperature and continue cooling treatments to bring their temperature down to 101-102°F. If possible, immerse them in a cool shower or tub of water. For young and healthy individuals who experience heat stroke during vigorous exercise, an ice bath can be used. However, do not use ice for older individuals, young children, or those with chronic illnesses.

Heat stroke can affect anyone, but certain factors increase the risk. These include age, with infants, young children, and adults over 65 being more vulnerable. Additionally, individuals with chronic health conditions, such as heart, lung, or kidney disease, obesity, high blood pressure, or diabetes, are at higher risk.

It is important to take preventative measures to avoid heat stroke, especially during hot weather or strenuous exercise. Stay hydrated by drinking plenty of water or sports drinks, wear lightweight and light-colored clothing, avoid excessive sun exposure during the hottest parts of the day, and refrain from excessive alcohol consumption.

It can lead to organ failure

Heat stroke is a serious medical emergency that occurs when the body is unable to control its internal temperature. It can lead to organ failure and even death. The condition results in a very high body temperature, typically exceeding 104°F (40°C), and the malfunction of many vital organ systems, including the heart, lungs, kidneys, liver, and brain.

The high body temperature associated with heat stroke can cause severe damage to these organs, and the risk of organ failure increases the longer treatment is delayed. It is crucial to seek immediate medical attention to prevent complications and reduce the risk of permanent organ damage.

One case study reported by Chiang Mai University in Thailand illustrates the potential severity of heat stroke-induced organ failure. A previously healthy 32-year-old man participated in a 30-km tricycle race in hot and humid weather. After biking for 25 km, he experienced heavy perspiration, severe muscle pain, and a high fever. He suddenly lost consciousness and was admitted to the hospital, where he was diagnosed with convulsions, and subsequent tests revealed anuria, anemia, thrombocytopenia, coagulopathy, and liver impairment. This case demonstrates how heat stroke can rapidly lead to multiple organ failure, even in young and healthy individuals.

Certain factors can increase the risk of heat stroke and its associated complications. These include age, with infants, young children, and adults over 65 being more susceptible. Additionally, certain prescription medications, obesity, sudden temperature changes, and high heat indexes can contribute to the development of heat stroke. It is important to recognize the symptoms of heat stroke, which include dizziness, weakness, nausea, vomiting, hot and flushed skin, rapid heart and breathing rates, and a body temperature above 104°F (40°C).

Heat stroke can be fatal

Heat stroke is a severe heat illness that can be fatal. It is a medical emergency and requires immediate treatment as it can lead to multi-organ dysfunction and even death. The condition results from a combination of high external temperatures and physical exertion, causing a person's body temperature to exceed 40.0 °C (104.0 °F). The hallmark symptom of heat stroke is a core body temperature above 104 °F, but fainting may be the first sign. Other symptoms include dizziness, light-headedness, behavioural changes, confusion, disorientation, nausea, seizures, and a lack of sweating despite the heat.

The risk of fatal heat stroke is higher in certain groups, including older people, young children, and individuals with chronic illnesses or taking certain medications. Those without access to air conditioning or good airflow are also more vulnerable. During a heatwave, it is crucial to take preventive measures such as staying in air-conditioned environments, wearing lightweight and light-coloured clothing, and staying hydrated.

If you suspect that someone is experiencing heat stroke, call emergency services immediately. While waiting for medical help, move the person to a cool, shaded area, remove unnecessary clothing, and initiate cooling strategies such as applying cold compresses or spraying them with cool water. It is important to monitor their body temperature and aim to reduce it to below 39 °C.

Delay in seeking medical help for heat stroke can be fatal, and even with treatment, severe cases can have a high mortality rate. Therefore, it is crucial to recognise the signs and symptoms of heat stroke and take preventive measures to avoid this life-threatening condition.

Heat stroke symptoms

Heat stroke is a serious medical emergency that occurs when the body is unable to control its internal temperature. It is important to know the symptoms of heat stroke to prevent serious complications, including death.

The first indication that someone is developing heat stroke is often the occurrence of heat exhaustion. Heat exhaustion is characterised by heavy sweating, weakness or tiredness, cool, pale, and clammy skin, a fast and weak pulse, muscle cramps, dizziness, nausea or vomiting, headache, and fainting. If someone is experiencing these symptoms, they should be moved to a cooler environment, given sips of water, and their clothing should be loosened. If the person vomits more than once, or their symptoms worsen or last longer than an hour, seek immediate medical attention.

Shivering may occur as a side effect of treatment for heat stroke, as the cold can cause involuntary muscle contractions. This may increase body temperature, so medication may be given to stop the shivering.

Heat stroke prevention

Heat stroke is a serious medical emergency that requires immediate attention. It occurs when the body reaches a temperature of 104°F or higher and can cause confusion, altered speech, nausea, rapid breathing, and a racing heartbeat. To prevent heat stroke, it is important to take the following precautions:

Stay in a Cool Environment

Try to stay in an air-conditioned place as much as possible. If you don't have air conditioning at home, spend a few hours in a shopping mall or public library to help your body stay cool.

Wear Appropriate Clothing

Choose lightweight, loose-fitting clothing in light colours. This will allow your body to cool properly.

Take Cool Showers or Baths

Taking a cool shower or bath can help lower your body temperature and prevent heat stroke.

Stay Hydrated

Drink plenty of fluids, especially water. Avoid alcoholic and sugary drinks, as these can cause you to lose body fluid. It is recommended to drink two to four cups of water every hour when spending time outdoors in the heat.

Avoid Strenuous Activities in the Heat

Limit your outdoor activities to the coolest times of the day, such as the morning and evening. If you must engage in strenuous activities, drink fluids and rest frequently in a cool spot.

Protect Yourself from the Sun

When outdoors, wear a wide-brimmed hat and sunglasses to protect yourself from the sun. Use sunscreen with an SPF of at least 30 and reapply it every two hours, or more often if you're swimming or sweating.

Be Cautious with Medications

Some medications can affect your body's ability to stay hydrated and dissipate heat. Consult your healthcare provider to understand any potential risks and take extra precautions if necessary.

Never Leave Anyone in a Parked Car

Cars can quickly heat up to dangerous temperatures, even with a window cracked open. Leaving someone in a parked car, especially a child or pet, can be life-threatening.

Know the Signs of Heat Exhaustion

Heat exhaustion often precedes heat stroke. Symptoms include cool, moist skin with goose bumps, heavy sweating, faintness, dizziness, fatigue, rapid pulse, headache, and nausea. If you experience these symptoms, seek prompt treatment to prevent heat stroke.
