Risks, Symptoms & Precautions You Need to Know

 

As the world grapples with climate change, heatwaves have become more frequent, intense, and prolonged. The current situation all across Pakistan has raised alarming concerns and issued weather warnings at national and provincial levels. High-temperatures exceeding bearable levels of heat can have devastating effects on human health, particularly for vulnerable populations. Heat-related illnesses, such as heat exhaustion and heatstroke, can be life-threatening if not recognized and treated promptly.

 

Who is at risk?

 

Certain groups are more susceptible to heat-related illnesses due to their occupation, living conditions, or health status.

- Outdoor workers, manual laborers, domestic help and athletes exposed to excess heat

- Urban and rural poor who live in low-quality housing with limited access to cooling

- People (mostly women) who are responsible for cooking indoors during hot weather

- People with pre-existing medical conditions, or any chronic illnesses such as cardiovascular disease, diabetes, and respiratory problems

- Infants, children, older adults and animals who may be more vulnerable to heat stress

 

 

Understanding heat-related illnesses

 

When the body is exposed to extreme heat, it can struggle to regulate its internal temperature. This can lead to a range of health problems, including:

HEAT EXHAUSTION a condition characterized by heavy sweating, pale skin, fast and weak pulse, nausea or vomiting, and dizziness

HEAT STROKE a life-threatening condition that occurs when the body's temperature regulation system is overloaded, causing the body temperature to rise rapidly


 

Preventing heat-related illnesses

 

- Stay out of the heat:  avoid going outside during the hottest part of the day, and stay in the shade or a cool place

- Keep your home cool:
use natural ventilation, shades and canopies, fans, Air conditioners and other cooling devices to keep your home at a comfortable temperature

- Stay hydrated:
drink plenty of water, juices, soft drinks, electrolytes regularly and avoid strenuous activities

- Protect vulnerable individuals:
check in on older adults, younger children, people with pre-existing medical conditions or disability, and those living alone or requiring extra care

- Never leave children or animals in parked vehicles:
as the greenhouse effect can cause internal vehicle temperature to rise which can quickly become life-threatening. Keep windows and doors open for air passage.

Heatstroke is a medical emergency that requires immediate attention. If you or someone else is experiencing any of the following symptoms, seek medical help right away:

- Fainting, dizziness, weakness, tiredness or loss of consciousness

Pointers for Healthcare and Relief Workers

 

For healthcare professionals, relief workers and volunteers; it's essential to be aware of the clinical guidelines for managing heat-related illnesses.

Mild heat illnesses

 rest, rehydration, and passive stretching for heat cramps; resolving spontaneously for heat edema and prickly heat

 

Moderate to severe heat illnesses

 aggressive cooling measures, such as immersion in cold water or using ice packs and fans, and activating emergency medical services

 

 

By understanding the risks and taking preventive measures, we can reduce the impact of heat-related illnesses and keep our communities safe during heatwaves.
