The harm of sand blowing weather to people

We usually call it "inhalable particulate matter". Because of its light volume, it can float in the atmosphere for a long time, and the floating range can reach tens of kilometers, which can cause continuous accumulation in the atmosphere and gradually aggravate the pollution degree. Floating dust can directly drive human body through collision, diffusion and deposition, invade human alveoli and stay in different parts of respiratory tract, and most of them with particle size less than 5 microns stay in upper respiratory tract. Particles trapped in the nasopharynx and trachea, together with harmful gases such as sulfur dioxide entering the human body, stimulate and corrode mucous membranes, damage mucous membranes and cilia, cause inflammation and increase airway resistance. Persistent effects can lead to chronic nasopharyngitis and chronic tracheitis. Particles trapped in bronchioles and alveoli can also combine with nitrogen dioxide, damaging alveoli and mucous membranes and causing inflammation of bronchi and lungs. The effect of floating dust can last for several years. A large amount of floating dust deposited on alveoli can cause chronic fibrosis of lung tissue, reduce the on-off function of alveoli, and lead to a series of pathological changes such as cor pulmonale and cardiovascular diseases.

Facing the influence of sandstorm on human body, individuals should take necessary protective measures;

First, when chronic cough is accompanied by expectoration or shortness of breath, wheezing and chest pain, you should go to the hospital as soon as possible.

Second, protect yourself. Dust storm weather, reduce going out, close doors and windows in time. If you must be outdoors, it is best to use a dust-proof mask to reduce the dust inhaled into the human body. Wet towel, gauze towel, etc. Can be used to protect eyes, mouth and nose. However, this simple protection can't stop the smaller particles. Other protective measures include wearing glasses, dust-proof gloves, shoes and socks, wearing clothes, protecting eyes and skin, and washing hands and faces frequently (especially before eating). Schools at all levels should temporarily stop outdoor activities before the sandstorm recedes.

Third, drink more water. Sandstorm-prone season, dry weather, coupled with dust, the water on the skin surface is easily lost, leading to rough skin. Dust is easy to clog after entering pores. If not removed in time, it may cause acne. People with allergies are also prone to various allergic dermatitis and rashes. Drinking plenty of water can replenish lost water and accelerate the discharge of various metabolic wastes in the body, which is very beneficial to skin care and general health.
