Indoor Air Pollution Against The Elderly

There are various sources of indoor air pollution. Outdoor air pollutants, such as particulate matter and gaseous pollutants, enter the room through the doors and windows of the living room and the gaps in the building, which increases the concentration of the corresponding indoor pollutants. Some buildings contain certain volatile harmful substances, such as radioactive radon in building stones and floor tiles.

There are also indoor pollution sources that are easily ignored by ordinary people. For example, in addition to water and carbon dioxide exhaled by humans and other organisms, there are also smoke from smoking, pollutants emitted from interior decoration materials, hydrogen sulfide emitted from toilets, and air filters, refrigeration coils, Bacteria and fungi growing in ventilation ducts and cooling water, cooking fumes, etc., can cause indoor air pollution.

Nowadays, many elderly people are prone to illness. Every year, a large number of cardiovascular and cerebrovascular diseases such as stroke and myocardial infarction and respiratory diseases such as asthma threaten many elderly people. On the one hand, it is due to the weakened physical function and weakened immunity of the elderly because of age, and on the other hand, it is also related to the environment in which we live, especially the indoor environment.

When the human body enters old age, various bodily functions are declining, and it is easier to be affected by environmental factors and induce various diseases. More than ten years ago, my country’s housing construction was basically made of raw wood materials, including paint, etc., all used raw materials. With the increase in housing demand and the continuous development of construction technology, a large number of artificial synthetic paints, composite reinforcement materials, etc. are used. Produced in batches, it has also been used in a large number of housing constructions, making it difficult for indoor air pollutants to volatilize and causing indoor environmental pollution. In modern life, the elderly live indoors most of the time, and are more prone to respiratory harmful substances. When the indoor pollutants exceed a certain standard, the elderly are prone to various diseases.

How harmful is indoor air pollution to the elderly?

Due to the weak immunity of the elderly, indoor air pollution often induces respiratory diseases such as asthma, weakened lung and function.

Indoor air pollution can lead to colon cancer and brain tumor in the elderly, and induce Alzheimer’s disease.

Living in a polluted environment for a long time will lead to weakened liver and kidney functions in the elderly. In addition, chemical pollution such as formaldehyde has a strong carcinogenic effect, which increases the incidence of cancer in the elderly.

A new study published in the March issue of the international journal “Journal of Hypertension” tells us that indoor air pollution not only damages the lungs, but also affects the cardiovascular and cerebrovascular of the elderly.
