Which of the following symptoms is associated with carbon monoxide exposure?

Headaches are commonly associated with carbon monoxide exposure due to its binding affinity to hemoglobin in the blood. When carbon monoxide is inhaled, it competes with oxygen for binding sites on hemoglobin, leading to decreased oxygen transport to tissues. This reduction in oxygen delivery can result in various symptoms, with headaches being one of the most prevalent. As the brain is particularly sensitive to changes in oxygen levels, the vascular changes and irritation in the brain caused by hypoxia can lead to the development of headaches.

Other symptoms of carbon monoxide exposure can include dizziness, confusion, and even loss of consciousness at higher levels, but headaches are often one of the first signs reported during exposure. Understanding the presentation of symptoms such as headaches helps in assessing exposure risk and implementing appropriate safety measures.
