This summer, there has been an alarming increase in heatstroke-related deaths worldwide. According to a recent report by the Intergovernmental Panel on Climate Change, extreme heat occurrences are becoming more frequent and lasting longer, affecting a larger number of people. Why is this happening, and how can you identify if your loved ones are at risk?
What occurs inside our bodies when our temperature rises?
Heat stress is caused by an accumulation of heat due to physical exertion or environmental stressors like solar radiation, air temperature, humidity, and wind speed. A person’s acclimatization, work type, physical activity level, and clothing also influence heat factors.
Humans are warm-blooded creatures, meaning the body’s internal temperature must remain around 37°C. If the internal temperature reaches 42°C, vital organs can cease functioning, leading to severe illness and death. 27 pathways Extreme heat can be lethal due to reduced blood flow and damage to essential organs.
Individuals most vulnerable to heat-related illnesses include those with poor thermoregulation capabilities, such as infants, elderly individuals, those with chronic illnesses, pregnant women, and outdoor workers.
What is heat stroke?
Heat stroke manifests when individuals experience heat stress and start feeling unwell. Various types of heat stroke exist. Heat stroke often accompanies dehydration, including conditions like heat syncope, thermal tetany, heat cramps, and heat exhaustion.
Another prevalent form of heat stroke is heat stroke, where the body struggles to regulate temperature, with categories like exertional heat stroke and classic heat stroke.

What steps should be taken if someone is suspected of having heat stroke?
If an individual faints, experiences concentration issues, or has breathing difficulties, immediate medical assistance is crucial. If they are conscious but feel unwell or overheated, rapid cooling and hydration are essential.
The most effective method to cool someone quickly is immersion in cold water, such as a bath, shower, or pool.
Caution must be exercised with very cold water to avoid cold shock, which can impact breathing, heart rate, and blood pressure. Ice water offers no advantage.
If complete submersion isn’t feasible, cooling extremities like feet, hands, neck, and face can help lower body temperature.
Replenishing lost fluids and minerals due to sweating from overheating is essential, so providing sports drinks can aid in hydration.
How can heat stroke be prevented?
Preventing heat stroke is feasible with measures such as issuing heatwave warnings, creating prevention plans, and staying hydrated during extreme heat periods. Hot drinks are as effective as cold ones, and temperature plays a minimal role in core body temperature.
Additional cooling methods include taking cool showers and focusing on cooling hands, feet, and face. Ventilating indoor spaces and avoiding direct sunlight can help maintain a cooler environment, while fans promote air circulation.
Vulnerable groups, like the elderly, should take extra precautions against heatstroke and follow advice from family and friends to stay hydrated and cool.
Babies are particularly susceptible to extreme heat, with techniques like covering strollers with damp cloths and using clip-on fans being more effective than thin blankets in protecting them from the sun.
Will the situation worsen?
While climate change intensifies extreme heat events, strides have been made in preventing heatstroke. Government strategies to prevent heatstroke are being implemented, with urban planning initiatives like creating green urban spaces to combat urban heat islands.
Initiatives like cooling centers, forecast-based financing, and early warning systems contribute to preventing heat-related illnesses. Achieving net-zero emissions is crucial to halting extreme heat escalation and averting catastrophic heatwaves.
This is imperative as the point at which even healthy individuals cannot survive without cooling devices is a distressing prospect. It’s a future we must strive to avoid.
