Coughing is a protective physiological reflex of the human body. Germs and sputum in the respiratory tract can be expelled from the body through coughing, which plays a role in cleaning the respiratory tract and keeping it open. Normally, organisms secrete fluid in the throat and bronchi to maintain humidity. When foreign matter such as pathogens or dust adheres to the throat or bronchi, the secretion of fluid will increase, sending impulses to the cough center of the brain, causing a physiological reflex – coughing. In addition, changes in temperature and other factors that irritate the throat and bronchi can also cause coughing. Some babies are fine during the day, but cough when sleeping at night. This is because the secretions from the nose and sinuses will flow into the throat when the baby is lying down, causing itchiness in the throat and triggering a new round of cough; another reason is the activity of the vagus nerve and sympathetic nerves that control the lungs, and sympathetic nerves control the lungs during the day. Nerve excitement inhibits coughing, while vagus nerve excitement at night causes bronchial smooth muscle contraction and increased glandular secretion, which increases airway resistance, resulting in dyspnea, wheezing and frequent coughing. This is a common condition among cough symptoms. If the inflammation intensifies, it will cause airway spasm, make the cough more severe, and even cause the child to be unable to lie down. Quick home remedies for what to eat when a child coughs: ▼Add more fluids and drink more boiled water to make it easier to cough up phlegm. You may want to let your baby drink warm boiled water or warm milk, rice soup, etc. You can also give your baby fresh fruit juice. Apple juice and pear juice, which are less irritating, should be used instead of orange juice, grapefruit juice and other citrus juices. Feed the baby in small amounts many times. ▼Pay attention to the position. If your baby keeps coughing when falling asleep, you can raise his head and pat his back. The coughing symptoms will be relieved. Elevating the head is helpful for most coughs caused by infection, because it will make it easier to discharge respiratory secretions and promote the dissipation of inflammation; if there are many secretions and affect breathing, use a suction device to remove sputum in time. Keep your airway open. People with cough and asthma symptoms can be given oxygen inhalation, and the sleeping position should be changed frequently. It is best to sleep on the left and right sides, which is conducive to the discharge of respiratory secretions. ▼ Go to the bathroom to inhale steam. If your baby has a severe cough, you can turn on the water heater and put in some hot water to spread the moist water vapor in the air. Hold your baby and sit in the steam-filled bathroom for a few minutes. The moist air will help your baby to clear the air. Mucus in the lungs, calms coughs. Ultrasonic atomization inhalation can also be used. ▼If you have a serious cough, you need to stop it. Coughing is an activity performed to expel phlegm from the body, so do not stop the cough casually. However, if your baby coughs so badly that he cannot sleep or drink breast milk or milk, you can use cough-relieving or phlegm-reducing drugs prescribed by your doctor. To relieve a baby\’s cough, it is not just about taking cough medicine, but also to treat the cause. For babies who cough, it is suitable to use cough medicines that have both expectorant and phlegm-reducing effects. Syrups are better than tablets. After taking the syrup, it adheres to the pharyngeal mucosa, weakening the irritation to the mucous membrane. It can achieve the purpose of antitussive by itself. When taking it, Do not dilute with water or take with water. It is best not to give cough medicine for adults to babies. ▼Adjust room temperature and humidity to keep the room temperature at 20℃~25℃. Parents should keep the air in the home fresh and exhaust fumes from the kitchen.Therefore, parents should avoid smoking at home, open windows regularly for ventilation, and maintain appropriate humidity. Add or remove clothes and quilts for the baby in time, try to let the baby rest in bed more, and ensure that the baby gets enough sleep to facilitate the body\’s recovery. Quick tips on what to eat for children with cough: 1. Coughing is not necessarily a disease. Modern medicine believes that biting cough is not a disease, but a symptom that may occur in many diseases. Baby biting and coughing is a body defense reflex to expel respiratory secretions or foreign matter. In other words, biting and coughing is a protective physiological phenomenon of the baby. But if the cough is too severe and affects diet, sleep and rest, then it loses its protective significance. Therefore, for coughs, it is necessary to identify the cause and then treat it accordingly. Never think of a cold or pneumonia as soon as you hear a cough and blindly treat it. 2. Formaldehyde exceeds the standard and the child coughs. When formaldehyde in the air in your home exceeds the standard, babies are usually the first to be harmed, and the main symptom is coughing. As living conditions improve, people often encounter this kind of \”happiness trouble\” after moving to a new home. Formaldehyde is a colorless, soluble, irritating gas that can be absorbed through the respiratory tract, and its aqueous solution (formalin) can be absorbed through the digestive tract. Modern scientific research shows that formaldehyde has a negative impact on human health. Long-term exposure to low-dose formaldehyde can cause chronic respiratory diseases, female menstrual disorders, infertility, reduced physical fitness of newborns, chromosomal abnormalities, and even nasopharyngeal cancer. High concentrations of formaldehyde are toxic to the human nervous system, immune system, liver, etc. 3. How to identify allergic cough in babies? Allergic cough can occur in babies of any age, and the cough occurs repeatedly or lasts for more than one month. The onset is not limited to winter and spring. Attacks are more common at night and in the morning, and coughing worsens when exercising or crying. Most babies\’ coughs are irritating and may produce sputum. There is often a family or personal history of allergies, and most babies have a history of infantile eczema and allergic rhinitis in infancy. Treatment with antibiotics and cough suppressants is ineffective.
