What to do if formaldehyde levels are excessive and causing dizziness and nausea
In general, if dizziness and nausea are caused by excessive formaldehyde exposure, it is recommended to immediately leave the polluted environment, increase fluid intake, engage in more physical activity, receive oxygen therapy, or take medication to alleviate symptoms.

1. Immediately leave the polluted environment: Formaldehyde is a harmful chemical substance that can damage the respiratory and nervous systems when inhaled. Dizziness and nausea indicate that the body has already been adversely affected by formaldehyde. Remaining in the contaminated environment will worsen symptoms. It is advised to quickly move to a place with fresh air and good ventilation, such as outdoors or a well-ventilated room.
2. Increase fluid intake: Formaldehyde is an inhalable toxic gas that may damage the nervous, digestive, and respiratory systems after inhalation. Symptoms may include dizziness, nausea, vomiting, breathing difficulties, and skin rashes. Drinking plenty of water is recommended to boost basal metabolic rate, promote formaldehyde elimination from the body, and relieve symptoms.
3. Increase physical activity: Increasing exercise can enhance metabolism. During physical activity, the body absorbs more oxygen, increasing blood oxygen saturation and alleviating oxygen deficiency in the nervous and respiratory systems caused by formaldehyde inhalation. This effectively reduces dizziness and nausea due to excessive formaldehyde exposure.
4. Oxygen therapy: Formaldehyde poisoning may lead to hypoxia, causing symptoms such as dizziness and nausea. Oxygen therapy increases blood oxygen levels, improves hypoxic conditions, and reduces discomfort like dizziness.
5. Medication: If symptoms caused by high formaldehyde levels are severe, oxygen therapy may be necessary to improve blood oxygen saturation and relieve symptoms. Under medical guidance, appropriate medications can be used for symptomatic treatment. Drugs such as flunarizine hydrochloride capsules or betahistine hydrochloride tablets may be taken to improve cerebral blood flow and reduce dizziness.
Excessive formaldehyde exposure significantly affects health. If related physical discomfort occurs, prompt medical attention is recommended. It's important to promptly leave the formaldehyde-contaminated environment. Additionally, in daily life, it's advisable to engage in moderate physical activities such as walking or jogging, while avoiding strenuous exercise.
