I don't think so, but that is a symptom of breathing in quantities of
carbon monoxide. Which is present in the combustion gasses of a gas
appliance. IIRC it's a simple test to check for CO in the blood so might
be worth seeing your doctor. And get a competent gas engineer to check all
the appliances you have.
