Can the fumes from burning magnesium cause a headache?

Yes, the fumes from burning magnesium can cause a headache.

Magnesium is a highly reactive metal that readily burns in air, releasing a bright white light and producing magnesium oxide fumes. These fumes are composed of tiny particles of magnesium oxide that can be inhaled and cause respiratory irritation, including a headache. Additionally, the high temperature generated during the combustion process can release other toxic gases, such as carbon monoxide, which can also contribute to headaches.

It's important to avoid exposure to magnesium fumes by taking appropriate safety precautions, such as working in a well-ventilated area or using respiratory protection. If you experience a headache or any other adverse health effects after exposure to magnesium fumes, seek medical attention promptly.
