What is a common symptom of carbon monoxide poisoning?

A common symptom of carbon monoxide poisoning is a headache. This occurs because carbon monoxide binds with hemoglobin in the blood more effectively than oxygen does, reducing the blood's capacity to carry oxygen. As the body's cells and tissues become deprived of oxygen, they can react in various ways. Headaches result from this oxygen deprivation, as the brain is highly sensitive to changes in oxygen levels.

It's important to note that while dizziness, nausea, and fatigue can also be associated with carbon monoxide exposure, the headache is often one of the first symptoms reported by individuals affected by this kind of poisoning. Understanding these symptoms can assist in recognizing carbon monoxide toxicity early, enabling timely medical intervention.
