Is carbon monoxide poisoning from burning charcoal painful?

Whether carbon monoxide poisoning is distressing depends on the severity of the poisoning. Mild cases may cause only slight discomfort, easily overlooked; severe cases can lead to intense suffering and even life-threatening conditions, requiring immediate emergency treatment. The details are as follows:

In mild poisoning, a small amount of carbon monoxide is inhaled, possibly causing only symptoms such as dizziness, headache, fatigue, and nausea—similar to common cold symptoms—with relatively mild discomfort. If the person promptly leaves the contaminated environment, moves to a well-ventilated area, and opens windows for air circulation, symptoms usually subside gradually without special medical intervention.

In severe poisoning, symptoms such as dizziness and headache intensify, accompanied by blurred vision, confusion, difficulty breathing, chest tightness, palpitations, vomiting, weakness in limbs, and even loss of consciousness. The discomfort becomes extremely severe. In such cases, emergency services must be called immediately. During transport, ensure the patient’s airway remains unobstructed—loosen the collar and place them in a lateral position to prevent airway blockage from vomit.

Prevention is key to avoiding carbon monoxide poisoning. When using charcoal for heating or cooking, ensure poor room sealing (i.e., adequate ventilation) and install proper exhaust systems. Use certified charcoal appliances and avoid burning charcoal for extended periods in small enclosed spaces such as bedrooms or bathrooms.
