The increasing frequency of heat waves poses a significant threat to public health, emphasizing the need to take proactive measures to avoid heat-related illnesses, particularly heat stroke and heat exhaustion.
Heat stroke is a severe condition that can lead to seizures, organ failure, and even death if left untreated. It occurs when the body temperature rises to extreme levels, damaging the brain and other vital organs. Before heat stroke sets in, individuals may experience a milder condition called heat exhaustion, which shares similar symptoms.
The body's natural cooling mechanisms, such as sweating and radiating heat, can be overwhelmed by hot and humid environments. This can happen to anyone, but certain factors increase the risk of heat exhaustion and heat stroke, including exercising in high temperatures, poor fitness, and dehydration.
Additionally, individuals with disabilities or illnesses that make it difficult to cool themselves or escape the heat are particularly vulnerable. Wearing heavy gear, drinking alcohol, and taking certain medications or supplements can also exacerbate the risk.
Heat exhaustion occurs when the core body temperature is elevated but not enough to affect the brain. If you or someone you know is showing signs of heat exhaustion, such as dizziness, nausea, headache, fatigue, or heavy sweating, seek medical help immediately.
Signs of heat exhaustion may include:
Dizziness
Nausea and vomiting
Headache
Fatigue or weakness
Heavy sweating
Cold, pale, and clammy skin
A fast, weak pulse
If symptoms persist or worsen, seek medical attention.
Heat stroke, on the other hand, occurs when the body temperature exceeds 104°F (40°C) and can affect the brain. The person may be too confused to realize they are in danger, making it essential to watch out for signs of the illness in others.
Signs of heat stroke include:
Confusion, irritability, or hallucination
Passing out or collapsing
Trouble walking
Seizures
Reddened skin, with or without sweating
If you suspect someone has heat stroke, call for medical help immediately. While waiting for assistance, you can help cool the person down by placing them in a tub of cold water, using a cold shower, or applying ice-cold wet towels to their body.
