How long does it take for a pregnant woman to stay in a room with formaldehyde?

A newly renovated house is usually not occupied until some time has passed, because after the renovation, a certain amount of formaldehyde will be produced in the room. Formaldehyde is a chemical substance. If it is dispersed in the air, it has a very strong smell. People who are often in such an environment are prone to illness and may also suffer from formaldehyde poisoning, especially for special groups such as pregnant women. So how long does it take for pregnant women to stay in a room filled with formaldehyde before it will have an impact?

Aldehyde residue. Pregnant women have special physical conditions. How long should they stay in a room with formaldehyde before it will have any impact? Let’s take a look together below!

1 How long does it take for a pregnant woman to stay in a room with formaldehyde?

Pregnant women are best to stay away from formaldehyde.

Everyone has a different physical condition, and the degree and type of environmental pollution are different. How long a pregnant woman stays in a room with formaldehyde will have an impact depends on the actual situation. Formaldehyde is a mutagenic substance, and long-term stay in polluted air can easily cause cell deformation.

2What will happen if pregnant women smell too much formaldehyde?

Induce respiratory diseases

Formaldehyde has the effect of inducing cell mutations. Pregnant women have poor immune systems and are prone to respiratory diseases, which will eventually affect the fetus in the womb.

Shorten pregnancy period

The reactions to formaldehyde poisoning are the same as those during pregnancy, including nausea, vomiting, dizziness, discomfort, etc. Pregnant women will not feel anything unusual. In fact, it is very harmful to the baby. Over time it will shorten the pregnancy period and even cause miscarriage.

3 Symptoms of pregnant women smelling too much formaldehyde

It manifests as irritation symptoms to the respiratory mucosa, skin, conjunctiva, etc., such as skin irritation, difficulty breathing, cough, sore throat, chest tightness, eye irritation and tearing. Routine physical examinations and chest X-rays will not reveal any abnormalities.

The eyes and upper respiratory tract reactions are prominent, with redness, swelling and congestion of the eyes, and breathing difficulties, shortness of breath, hoarseness of voice, dry throat, etc. In addition, there are symptoms such as blurred vision, dizziness, and general weakness. The poisoned person can clearly feel the difficulty in breathing, and a chest X-ray examination in the hospital will reveal enhanced lung texture and throat edema of one to two degrees.

Symptoms include constant coughing, sputum, chest tightness and pain, extreme difficulty breathing, and hoarse voice. A chest X-ray will show that the lung texture changes into scattered small spots and mass shadows, which is medically known as bronchopneumonia. Throat edema increased to grade three. The poisoned people suffer from mild to moderate hypoxia.

Symptoms include worsening of lung and throat conditions, redness and swelling of the laryngeal area, as well as suffocation and pulmonary edema. The poisoned person suffers from severe hypoxia and is prone to coma and shock.

4Main hazards of formaldehyde

This is the most basic hazard. Formaldehyde has a strong irritating odor, which can irritate the skin, eyes, respiratory mucosa, etc., causing skin stinging, red and swollen eyes, tears, and difficulty breathing. Pregnant women with low immunity are particularly susceptible to being affected if they stay in a room containing formaldehyde for a long time. It may even irritate the fetus through the placenta, and in severe cases, cause congenital malformations in the fetus. Therefore, pregnant mothers must be careful and try not to go to newly renovated houses. If you have to go, be sure to reduce the time you spend inside.

Long-term exposure to formaldehyde can easily cause skin allergies, inflammation, necrosis, and pigmentation. If high-purity formaldehyde is inhaled, it can easily cause asthma. Once an expectant mother develops asthma, it will affect the fetus in her womb and increase the incidence of unexpected situations during delivery.

Generally speaking, inhaling formaldehyde will cause varying degrees of skin tingling, dizziness, weakness, nausea, retching, sore throat, chest tightness, eye pain, etc.; inhaling too much will also cause symptoms such as insomnia, weight loss, memory loss, and autonomic nervous system disorders. Pregnant women are particularly vulnerable to harm once they inhale formaldehyde.

It has been confirmed in animals that long-term inhalation of high concentrations of formaldehyde gas can easily induce rhinitis and tumors. Experiments have also shown that high concentrations of formaldehyde gas are a genotoxic substance and its mutagenic effects are very severe. Pregnant women should be especially careful to avoid affecting the health of the fetus in their womb.

5 How long does it take for a pregnant woman to move into a house after renovation?

Indoor air quality inspection should be carried out for indoor decoration projects 7 days after completion. This means that you can only move in after at least 7 days of renovation and after the air quality inspection has been passed.

For pregnant women, after the house is renovated, if the acceptance meets the standards, try not to move in immediately; if the acceptance does not meet the standards, you cannot move in even if the house has been renovated for more than half a year. It is necessary to wait until the indoor air quality test is qualified before deciding to move in.

6 Ways to Remove Formaldehyde

This is the simplest method, which reduces the content of harmful gases in the room by circulating indoor and outdoor air. Many families often keep their doors and windows closed during the cold winter. People indoors have red faces due to lack of oxygen, and the air is not circulating, which not only increases the formaldehyde content, but also the nitrogen content, endangering human health.

This method is also extremely simple, but it is only suitable for medium and low levels of pollution. Choose and place plants according to the size of the room. Generally speaking, a room of about 10 square meters can hold two or more pots of plants.

This method is also relatively cheap and practical. Activated carbon can deodorize and absorb drugs. Its principle is physical adsorption, and the adsorption is thorough. What makes activated carbon reassuring is that it does not contain any chemical ingredients and can be used with confidence.

This is a high-tech nano-absorption technology that combines natural nano-raw materials with general oxidants to remove harmful gases from indoor environments. Its function is so powerful that it can not only effectively absorb formaldehyde, but is also effective against ammonia, benzene, carbon monoxide, etc.

In addition to the above methods, there are also black tea method, chemical method, pure Chinese herbal spray decomposition method, etc., all of which have obvious effects on removing formaldehyde gas. Expectant mothers may wish to try them.
