Respiratory infections are a very common disease, including various types of flu, influenza and pneumonia, which seriously affect people ‘ s health and quality of life. Effective preventive measures can significantly reduce the risk of respiratory infections.
First, maintaining good hygiene practices is the basis for preventing respiratory infections. Hand-washing is a key step in which hand-washing is carried out with soap and running water after meals, after exposure to public goods, after coughing or sneezing, for no less than 20 seconds, to ensure that the heart, back, finger stitches and nails are cleaned. In the absence of mobile water, hand-washing fluids containing alcohol can also be used for cleaning. In case of cough or sneeze, cover your nose and mouth with paper towels to avoid the spread of foam. If the paper towel is not available, the inside side of the elbow should be used to cover the nose and nose instead of the hand, as there are more items exposed to the hand and the virus can easily be transmitted elsewhere. When used, paper towels should be thrown into the trash can and wash hands as soon as possible.
Increased indoor ventilation is equally important. The windows should be ventilated on a regular basis every day to allow fresh air to enter the room, dilute and remove possible viruses and bacteria. It is generally recommended that there should be 2 – 3 ventilations per day for no less than 30 minutes each. In particular, there is a need to improve ventilation in densely populated locations, such as offices, classrooms, etc. During cold seasons, when ventilated, care is taken to keep warm and to avoid cold. In addition, the maintenance of indoor sanitation, regular cleaning of the ground, cleaning of furniture, cleaning of curtains, etc., reduces the accumulation of dust and allergies and also helps to prevent respiratory infections.
Increased self-immunization is central to the prevention of respiratory infections. A balanced diet is an important guarantee of increased immunity. The daily diet should contain abundant proteins, such as skinny meat, fish, beans, eggs, dairy products, etc., to provide the body with the raw materials for repair and immunocellation. More fresh vegetables and fruits, which are rich in antioxidants such as vitamin C, vitamin E, beta-carrotin, can increase the resilience of organisms to oxidation and protect cells from free radical damage, thus increasing their immunity. For example, fruits such as oranges, lemons and monkeys are rich in vitamin C, vegetables such as broccoli, spinach and carrots are rich in vitamins and minerals. At the same time, adequate water intake is ensured and 1,500 – 2000 ml of water is consumed daily, which helps to maintain the moistification of the mucous membranes of the respiratory tract, making it difficult for pathogens to bind and invade.
Moderate physical exercise is essential for increased immunity. Aerobic activity of a medium intensity of at least 150 minutes per week, such as walking, jogging, swimming, cycling, etc., can also be combined with force training such as weight lifting, push-ups, sit-ups, etc. Sport promotes blood circulation, enhances CPR function, increases the metabolic level of the body, and makes immune cells more active. Care must, however, be taken to rationalize the strength and timing of the exercise and to avoid excessive fatigue and physical damage.
Vaccination is an effective means of preventing specific respiratory infections. Influenza vaccine can be effective in preventing influenza virus infections, and vaccination against influenza before the onset of the annual influenza season can significantly reduce the risk of influenza and reduce its symptoms. Inoculation against influenza is particularly important for the elderly, children, pregnant women and people with low levels of immunity, such as chronic diseases. Pneumonia vaccine, for example, prevents pneumonia caused by streptococcus, and it is recommended that specific groups at high risk be vaccinated as recommended by a doctor.
During the epidemiological season of respiratory infections, access to densely populated and air-traffic sites, such as malls, cinemas, theatres, etc., is minimized. If travel is necessary, it is advisable to wear masks and reduce close contact with others. Masks can effectively prevent the spread of foam and reduce the likelihood of infection. In addition, maintaining a regular rest time, avoiding lateness, ensuring adequate sleep and adequate rest and recovery of the body will also help maintain a good state of immunization against respiratory infections. In sum, a combination of the above-mentioned preventive measures can significantly reduce the likelihood of respiratory infections and protect the health of themselves and others.
