Electric space heaters can be dangerous in winter. LAWTON Okla_ Electric space heaters can be dangerous as the winter days get colder. Overnight temperatures are now regularly dropping below freezing, and people are using electric space heaters. Some don't use them correctly, and they can quickly create a danger.
However... if you were trying to heat a small, poorly insulated bedroom with an electric heater and tightly sealed up all the little air cracks and such to an extreme extent, then yes, it could be unhealthy: not because of the heater but because you sealed up all the air exchange so thoroughly.
