An important but uncommon cause of headaches is carbon monoxide exposure. Clues that carbon monoxide may be the cause include:

- Headaches that occur only in your home

- Cold weather requiring windows to be shut

- A gas smell in your home

- Using a wood burning or coal stove

- Other family members complaining of headache

Is there any chance that carbon monoxide levels are high in your home?

Yes, this may be true.

No, this does not apply to me.
