How is 'dry blindness' dangerous to health?

This phenomenon is appearing in Ho Chi Minh City and neighboring provinces, very dangerous health. The eyes and respiratory tract are directly affected if there is no timely response.

Harmful effects of dry blind that you do not know

According to experts, the most obvious impact of dry blindness is hindering vision , causing problems in transportation, congestion and traffic accidents. In particular, the phenomenon of dry blindness due to dust pollution is suspended in the air layer near the ground, it will certainly have a direct impact in the direction of harm to people's health.

As forecast, this situation will last for a few days. In addition, the time of season allocation is September-November 11, dry blind will repeat many times. This makes many people worried.

BSCKI Vu Thi Huyen Trang, Ear - Nose - Throat Hospital said that dust and environmental pollution is very harmful to health. People infected with dust can lead to upper respiratory infections such as pharyngitis, rhinitis, even superinfection leading to lower respiratory infections such as bronchitis, pneumonia .

According to Dr. Xuanzang, with a high concentration of dust in the air, ordinary masks cannot protect people when they are in traffic. Therefore, people should be equipped with activated carbon masks to ensure health. In addition, after returning home, we should use physiological saline to clean the nose and gargle to prevent dust.

According to the master, Le Quoc Viet Dermatologist, Dermatology Clinic, Hanoi Dermatology Hospital, air dust due to pollution or dry blind does not immediately cause skin diseases but they is a place that contains many pathogens, agents that carry bacteria, viruses, and mold into the human body if exposed long term and depending on the location of each person. This phenomenon also disturbs the humidity of the air, negatively affecting our skin.

Three towers of Thuan Kieu Plaza and a high-rise building in District 5 area are in fog of the evening of October 6.

Dr.BS Do Quang Ngoc, Central Eye Hospital, also recommends that the hospital has received many cases of eye and corneal infections due to dust and gas. Therefore, doctors recommend that people who are exposed to dry blindness need to be more alert, better eye protection.

'In parts, eyes are the first and direct contact with dust outside the environment. They are agents that cause water-secreting eyes to cause inflammation and dust can cause stubbornness, discomfort, even scratching the cornea if angled, ' Dr Ngoc said.

To protect the eyes, according to Dr. Ngoc, people need to wear goggles when going out; Daily eye hygiene with salt water; limiting movement to the impacted areas of dry blindness.

In addition, people can also suffer from intestinal diseases caused by environmental pollution such as acute diarrhea, cholera, dysentery, typhoid, helminths caused by eating unsafe and unshielded food sources. . In particular, the composition of carbon dioxide, carbon monoxide, lead and other toxic chemicals will have the most health impact on the respiratory, cardiovascular and nervous system.

Mr. Dang Van Dung, Deputy Director of the Southern Hydrometeorological Station of the Southern Region (KTTV-NB) said that the fog layer in Ho Chi Minh City and some neighboring provinces is in fact due to environmental pollution.

Huge amounts of emissions and fumes emitted from factories, enterprises and vehicles accumulate in the lower air layer close to the ground. Normally, the wind will push this layer of smoke up high. Two days now, the southwest monsoon works weakly in the Southern region. Therefore, dust and smoke cannot be diffused, causing dry blindness.

Meteorological expert Lu Thi Thu Trang added: ' Normally, morning fog is the phenomenon of tiny droplets flying in the air reducing visibility. And the dry blind is not the water particles, but the dust particles, which appear when the humidity drops below 75%. Air with too much dust and exhaust gas, reducing visibility, will create dry blindness'.

Compared to fog, dry blinds cause more dangerous levels of environmental pollution . The stronger the dry blind, the higher the pollution, seriously affecting health.

'To overcome this situation, there is only a way to make the environment cleaner and less waste and forest fire. However, the country is in the process of development so the emissions are increasing. Therefore, this phenomenon is becoming more and more easy to meet , 'Trang said.

Principle of living with dry blind:
