Dizziness, nausea, and a dull headache aren't just fatigue-they could be the first signals that your body is dangerously overheating. Recognize them in time and prevent heatstroke.
High summer temperatures bring health risks, and heatstroke is often not taken seriously enough. Many attribute the initial symptoms to fatigue or dehydration, but in reality, it is a serious condition that requires a quick response. Recognizing the early signs the body sends can be crucial in avoiding dangerous heatstroke.
The early signs of heatstroke can be very subtle. It typically begins with a dull headache, dizziness, nausea, and general weakness. These symptoms can easily be mistaken for temporary fatigue, but the body is already warning that its cooling system isn't working properly. The skin may be hot and red, and the pulse may be rapid. If these signs are ignored, the condition can quickly escalate from heat exhaustion to heatstroke, according to Ordinacija.hr.
When body temperature rises to 40 degrees Celsius or higher, it's a clear sign that the situation is serious. Sweating may then change, the skin may become hot and dry, or, if it's due to physical exertion, remain heavily sweaty. Breathing becomes shallow and rapid, which is an additional sign that the body is overwhelmed.
The most alarming sign that the condition is critical is neurological changes caused by the effect of high temperature on the brain. The person may become confused, disoriented, agitated, or even aggressive. Speech may become slurred, and delirium, seizures similar to epileptic ones, and in the most severe cases, loss of consciousness may occur.
“Any change in mental clarity or behavior in a person exposed to heat is an absolute alarm for emergency medical intervention. Brain damage and damage to other vital organs become a serious threat the longer the body remains overheated,” states the article on Ordinacija.hr.
Although no one is completely protected from heatstroke, some groups are much more vulnerable. Children and people over 65 are the most at risk because their bodies have a harder time regulating temperature. People with chronic heart, lung, or kidney diseases, as well as obese individuals, are also at higher risk.
Certain medications, such as diuretics, beta-blockers, and some antidepressants, can increase the risk because they interfere with natural cooling or cause dehydration. Intense physical activity in the heat, often seen in athletes and outdoor workers, and alcohol consumption further accelerate the development of the dangerous condition.
If you suspect heatstroke, call emergency services immediately. While waiting, the most important thing is to cool the person down as quickly as possible. Move them to the shade or an air-conditioned room and remove excess clothing. Cool them by any means possible: spray them with cool water or apply cold, wet compresses to the neck, armpits, and groin.
If the person is conscious and not confused, give them water in small sips. Never give fluids to someone who is losing consciousness. Do not use fever-reducing medications like paracetamol, as they can worsen organ damage. A quick response and cooling can prevent permanent consequences, as concluded in the advice from Ordinacija.hr.
