Air pollution - the impact of external factors on human health
Air pollution has a significant impact on people's respiratory system, especially emissions from transport vehicles, which are very harmful to the lungs. In addition, fine dust is the most dangerous pollutant because it exists for a long time in the air and disperses very far. Because of its small size, if it penetrates deep into the lungs and blood it will cause diseases such as respiratory disease, infertility. Air pollution also makes people tired to experience dizziness, headaches, and heart problems. Each target group will be affected differently depending on health status and pollution levels but the most affected people are the elderly, pregnant women, sick person, children under 15 years old.
In addition, heat waves or noise also cause certain harm to people. Noise is more likely to cause injury to the ear but also causes headaches, stress, nervous stress.
