What is a common symptom of carbon monoxide poisoning?

Headache is a common symptom of carbon monoxide poisoning due to the way carbon monoxide interacts with hemoglobin in the blood. When inhaled, carbon monoxide binds to hemoglobin much more effectively than oxygen does, which leads to a reduction in the blood's ability to transport oxygen. This deficiency in oxygen can result in various symptoms, with headaches being one of the first and most frequent ones experienced.

Individuals exposed to carbon monoxide may feel pressure or pain in their head, similar to a tension headache. This is often accompanied by other symptoms such as dizziness, confusion, or nausea as carbon monoxide levels in the blood increase. Recognizing headache as a potential sign of carbon monoxide exposure is crucial for timely intervention and treatment, especially since the gas is odorless and colorless, making it particularly hazardous in enclosed spaces.
