Extreme Heat Risk: Heatstroke Danger
During the summer season, when temperatures consistently soar, heatstroke (or sunstroke) becomes a health threat that many might overlook. In reality, it can be severe, even fatal, especially for high-risk groups such as children, the elderly, and those with underlying health conditions.

According to data from the Department of Disease Control, between 2015 and 2021, there were 234 deaths from heatstroke, averaging about 34 deaths per year. During the same period, the number of patients was as high as 2,500-3,000 per year.

Types of Heatstroke

Classic Heatstroke (CHS): This is typically found in the elderly, young children, or individuals with pre-existing medical conditions whose bodies have a reduced ability to regulate temperature.
Exertional Heatstroke (EHS): This occurs in individuals who engage in activities outdoors or in extremely hot environments, such as outdoor workers.

Dangerous Signs of Heatstroke

Body temperature above 40°C (104°F)
Absence of sweating
Rapid breathing, fast heartbeat
Dizziness, weakness, fainting
Dry and red skin
Nausea, vomiting
Confusion, slurred speech, seizures, or loss of consciousness

High-Risk Groups to Watch Out For

Children under 15 years old and the elderly
Individuals with underlying health conditions such as diabetes, hypertension, or heart disease
People who have not had enough sleep or rest
Individuals who are overweight or consume alcohol
Those who must work or play sports outdoors

First Aid for Heatstroke Patients

Immediately move the patient out of the hot environment.
Lay the patient flat and elevate both legs.
Loosen their clothing.
Use a cold, wet cloth to apply compresses to the armpits, groin, and forehead.
If the condition does not improve, seek immediate medical attention at a hospital.

Heatstroke Prevention Guidelines

Avoid sun exposure or outdoor activities on extremely hot days.
Wear breathable, light-colored clothing.
Drink water frequently; avoid alcohol and caffeine.
Closely monitor children and the elderly.
Carry sun protection items such as hats, umbrellas, and sunglasses.

Even though heatstroke might seem like a common illness, it can affect anyone if the body faces excessively high temperatures without proper care. Therefore, awareness and preparation are the best ways to reduce the risk and protect our health this summer.
