Warning Signs of Heatstroke: A Matter of Life and Death
As the summer months approach, the risk of heat-related illnesses increases, with heatstroke being one of the most severe and potentially life-threatening conditions. Heatstroke occurs when the body's temperature regulation system fails, causing the core temperature to rise rapidly above 40°C (104°F). This can happen when individuals are exposed to high temperatures and humidity, engage in strenuous physical activity, or are unable to cool down properly. The symptoms of heatstroke can be severe and include body temperature above 40°C (104°F), central nervous system disturbances, such as confusion, seizures, and loss of consciousness, headache, nausea, and vomiting, muscle weakness, cramps, or spasms, rapid heartbeat and breathing, and dehydration and dry skin.

If you suspect someone has heatstroke, it is crucial to act quickly and seek medical attention immediately. While waiting for emergency services to arrive, there are steps you can take to help reduce the person's body temperature, such as moving them to a shaded area, removing excess clothing, and using cool water to lower the body temperature by applying it to the skin or giving a cool shower. However, avoid giving the person anything to drink, as this can exacerbate the condition. It is also essential to avoid using ice or ice water, as this can cause the body to go into shock.
Prevention is key in reducing the risk of heatstroke. Effective measures include staying hydrated by drinking plenty of water and electrolyte-rich fluids, avoiding engaging in strenuous physical activities during the hottest part of the day, taking regular breaks to cool down in a shaded area, wearing lightweight, light-colored clothing that allows for good airflow, and never leaving children or pets unattended in a parked car. Additionally, it is crucial to recognize the warning signs of heatstroke, which can include dizziness, fatigue, softness in the hands and feet, headache, blurred vision, nausea, and vomiting, as well as critical distinguishing features such as body temperature exceeding 40°C, accompanied by brain function disorders.
Recognizing these warning signs and taking prompt action can mean the difference between life and death. The "846" golden rule can be a useful guide in preventing and treating heatstroke, particularly for high-risk groups such as outdoor workers, older adults, and patients with chronic illnesses. This principle outlines four warning signals that indicate a high risk of heatstroke, including feeling overheated, dizziness, fainting, and confusion, and six emergency measures to address these symptoms, including moving the person to a shaded area, removing excess clothing, using cold water to cool the body, applying cold compresses, and seeking medical help promptly.
By being aware of the risks and taking preventive measures, individuals can reduce their risk of heatstroke and stay safe during the sweltering summer months. If symptoms persist, it is essential to seek medical attention immediately and follow proper treatment and care. Heat stroke is a medical emergency that requires immediate attention, and prompt medical treatment is critical to prevent long-term damage to the brain, heart, and other organs. Stay calm, act quickly, and seek medical help as soon as possible if you suspect someone has heatstroke.
