What symptoms can indicate exposure to Carbon Dioxide?

Exposure to carbon dioxide (CO2) can lead to a range of symptoms primarily affecting the nervous system and respiratory system. The symptoms include headache, dizziness, and restlessness. These indications result from elevated levels of carbon dioxide in the blood, which can occur in confined spaces where air circulation is limited.

Headaches can arise from increased CO2 levels, as it can cause a decrease in oxygen availability to the brain. Dizziness may also be experienced due to alterations in blood gas levels affecting brain function. Restlessness is often a response to discomfort or a lack of adequate oxygen, creating a feeling of anxiety or agitation. In environments with high CO2 levels, these symptoms can escalate and may lead to more severe consequences if exposure continues without intervention.

Other symptoms such as fever and chills, coughing and sneezing, or rashes and skin irritations are not typically associated with carbon dioxide exposure. Fever and chills are generally linked to infections or illness, while coughing and sneezing are usually symptoms of respiratory infections or allergies. Rashes and skin irritations typically are caused by allergens or irritants rather than gas exposure. Thus, the correct answer focuses on the symptoms that are directly linked to carbon dioxide exposure.
