With the development of society, there are various professions have emerged. Many jobs require people to stand or sit for a long time. Many of us may know that standing for a long while will get varicose veins while sitting for a long while will get fat, get hemorrhoids or get cervical spondylosis. Actually, doing some jobs will get the so-called occupational disease, but the premise is that you are doing one of these kind of jobs for a long time.

According to the Wikipedia, an occupational disease is any chronic ailment that occurs as a result of work or occupational activity. It is an aspect of occupational safety and health. An occupational disease is typically identified when it is shown that it is more prevalent in a given body of workers than in the general population, or in other worker populations.
So there are many people who are not willing to do some jobs because of the occupational diseases. But in fact, we can do something to prevent these diseases or lower the risk of it. today, I’m going to introduce some occupational diseases and how to prevent them. Let’s take a look.
1. Lung Diseases
The lung diseases also called pneumocoinosis, which is a group of occupational lung diseases mainly because of the diffuse fibrosis of lung tissue caused by long-term inhalation of dust and retention in the lungs during occupational activities. The main manifestations are cough, sputum expectoration, chest pain and dyspnea. Usually, the course of the disease is long. Even if is out of dust contact environment, the condition will still progress and aggravate, requiring lifelong rehabilitation.

Pneumoconiosis usually presents a chronic course of clinical manifestations. In the early stage of pneumoconiosis, due to the large physiological function potential of the alveoli, the lung has a strong compensatory ability, and most patients have no obvious symptoms. But as the course of the disease progresses, the symptoms gradually become apparent.
So we’d better discover the disease at early stage. So in our daily life, we have to take some measures:
Firstly, you should actively understand pneumoconiosis-related knowledge in daily life and enhance awareness of safety protection. Secondly, these workers who working with high concentrations of dust must take protective measures and use protective equipment, including dust-proof masks, dust-proof helmets, dust-proof clothing, and dust-proof glasses. Thirdly, people with contraindications for dust operations are not allowed to participate in dust operations. Fourthly, those who are exposed to dust should go to the hospital for health check every year to find hidden dangers in time and receive treatment as soon as possible to minimize the harm to the body.
2. Skin Diseases
The so-called occupational skin diseases refer to diseases of the skin and its attached illness caused by occupational factors such as chemicals, physical factors and biological factors. Mainly manifested as dermatitis (allergic), acne, burns, melanosis, etc.
Occupational skin diseases are ranked among the top five occupational diseases in many countries. What are the common occupational skin diseases?
The first type is the dermatitis, eczema type. This is the most common type of occupational skin disease. The cause can be irritation or allergy. Inflammation can be acute, subacute or chronic. A variety of acids, alkalis, metal salts, organic solvents, petroleum products, dyes, resins (natural or synthetic), rubber, drugs, etc. can cause disease. The incidence of liquid contact objects is mostly on fingers, back of hands or forearms; aerosol contact objects are mostly on eyelids, face, neck and back of hands; dust contact objects are mostly on shoulders, neck, trunk and limbs covered and easily rubbed.

The second type is the acne, folliculitis type. The pathogens are mostly coal tar and petroleum processed products such as mineral oil, asphalt, paraffin, etc. Young workers and those with strong sebum secretion are prone to it. The site is mainly on the extensible side of the extremities, so it is different from that of acne on the face.
The third typeis the chemical burn type. It occurs on the skin and mucous membranes. The cause is long-term exposure to low concentrations of primary irritants, fluoride, chromate, arsenide, zinc chloride, calcium carbonate, etc. Small abrasions on the skin often occur first. The ulcer is round or oval, small and deep, with dry gray-black scabs on the surface, and raised edges. The entire ulcer looks like corns.
The final common type is the impetigo typ. The disease is caused by antimony powder, arsenic and aniline.
Because the occupational skin diseases is the top five disease in the occupational disease, and in our daily life, we are always get the skin peoblems. We should protect our skin at anytime, anywhere. So how we protect and prevent?
Firstly,patients with skin diseases should pay attention to eating less spicy and irritating food, and avoid contact with dry pots in the kitchen. Secondly, it is not suitable to eat “inducement food”, such as chicken, shrimp, fish, crab, etc. thirdly, in our daily life, we should avoid germs, skin damage and infection, and pay attention to personal hygiene. Also, we should avoid exposing our skin in the sunlight.

Indeed, the above measures are for you to prevent, if you have got skin diseases, you’d better to see the doctor.
3. Other diseases of concern
There are some other diseases because some professions. Such as lead posioning and occupational asthma and so on.
Lead posioning affecting workers in many industries that processed or employed lead or lead compounds. Chronic exposure to lead for a long period of time often causes fatigue, metallic taste in the mouth, muscle and joint aches in the early stage, followed by neurasthenia syndrome, loss of appetite, abdominal pain, constipation, etc. A few of the gums may have blue-black lead lines. When it get worse, people would feel their muscle paralysis, and even can not feel their limbs.

How people prevent lead posioning? The general principle is to lower the air lead concentration in the production environment to make it reach the sanitary standard is the key to prevention. At the same time, personal protection should be strengthened.
Occupational asthma is actually a disease caused by exposure to some substances during the production process. It is actually a type of bronchial asthma. It is also an obstructive disease. The symptoms will worsen in winter and spring and cause occupational asthma. Many of the complications seriously affect our physical and mental health.
For patients with occupational asthma, the emphasis is on early detection and early diagnosis. When the lung function is normal and the pathogenic factors are clear, a complete recovery can be achieved by leaving the original working environment in time. There are many factors that affect the prognosis of patients with occupational asthma, including exposure time, age of onset, degree of atopic physique, degree of lung damage and airway responsiveness. When the patient has irreversible airway obstruction and chronic obstructive pulmonary disease or other complications, the prognosis is poor.

The above are some commom occupational diseases and their prevention in our daily life, if your job is not in the above professions, you also can look through this article, just in case. I hope the above imformation can be helpful to you.
