Initial Physical Reactions to Excess Formaldehyde Exposure

The initial physical reactions to excessive formaldehyde exposure mainly include the following: 1. Respiratory symptoms: such as shortness of breath, sore throat, coughing, and, in severe cases, difficulty breathing. Formaldehyde strongly irritates the respiratory tract, and long-term inhalation of high concentrations can cause respiratory damage. 2. Eye discomfort: symptoms such as dryness, redness, swelling, and continuous tearing of the eyes. The eyes are sensitive organs and are easily irritated by formaldehyde. 3. Skin symptoms: skin allergies may occur, including skin inflammation such as redness, rashes, and itching, especially on areas such as the face, hands, and neck that are exposed to air for extended periods. 4. Neurological symptoms: dizziness, headache, and fatigue; in severe cases, symptoms such as cerebral hypoxia and loss of consciousness may occur. If the above symptoms appear after exposure to formaldehyde, one should be highly alert and seek medical attention promptly.
