Formaldehyde is naturally produced in very small amounts in our bodies as a part of our normal, everyday metabolism and causes us no harm. It can also be found in the air that we breathe at home and at work, in the food we eat, and in some products that we put on our skin.
As discussed above, formaldehyde can induce several symptoms, such as watery eyes, runny nose, burning sensations in the eyes, nose, and throat, and headaches. These symptoms may also occur because of the common cold, the flu, or other pollutants that may be present in the indoor air.ormaldehyde exposure can cause a variety of symptoms and potential adverse health effects. A. personâs ability to smell a chemical odor, such as formaldehyde, does not always mean that the. levels of the chemical are of concern or will cause an adverse health effect.
