UK warns of carbon monoxide risk from gas stoves, urging detectors and vigilance during Christmas cooking.

The UK Health Security Agency warns households using gas stoves during Christmas cooking to be alert for carbon monoxide leaks, which can be deadly. Over half of UK homes have gas hobs, and faulty appliances or supply lines may release the odorless, colorless gas. Symptoms include headaches, dizziness, nausea, and confusion. The agency urges installing working carbon monoxide detectors, checking for warning signs like yellow flames or soot, and seeking immediate medical help if symptoms occur, including calling 999 for severe cases.
