Introduction
Whether formaldehyde causes permanent damage to the human body mainly depends on the level of exposure. Brief or low-level exposure generally does not result in permanent harm; however, long-term exposure to high concentrations may lead to permanent damage. It is advisable to avoid prolonged contact with formaldehyde as much as possible, particularly by ensuring proper ventilation in newly renovated homes and selecting building materials and furniture with low formaldehyde emissions.
Generally, whether formaldehyde exposure causes permanent harm to the human body mainly depends on the level of exposure. If the contact is minimal, it typically does not result in permanent damage; however, long-term exposure to high concentrations may lead to permanent harm. Detailed analysis is as follows:
If one is only briefly exposed to a low-concentration formaldehyde environment and promptly takes effective protective measures, such as leaving the contaminated area and ventilating the space, the harm caused by formaldehyde may be mild and temporary, possibly manifesting as symptoms like tearing, nasal congestion, sneezing, and throat pain. These effects typically do not result in permanent damage after a period of rest and recovery.
However, if one is exposed for a prolonged period to a high-concentration formaldehyde environment, or if the individual has a weak constitution or is particularly sensitive to formaldehyde, the damage may be more severe and could even result in permanent injury. Long-term exposure to formaldehyde may trigger respiratory diseases such as chronic bronchitis and emphysema, as well as neurological symptoms like headache, insomnia, and difficulty concentrating, which may cause irreversible damage to the body.
It is important to avoid prolonged contact with formaldehyde as much as possible, especially in newly renovated homes, where proper ventilation and the selection of low-formaldehyde building materials and furniture are essential. If symptoms of formaldehyde poisoning occur, prompt medical attention and standardized treatment should be sought.
