Why does my child keep having a dry cough?

Sometimes, coughing due to a cold is a very normal thing, but after the cold is cured, the child still keeps coughing, and it is a dry cough. Many people don’t know what’s going on. Of course, the most important thing to do is to find out the cause of the disease, because in addition to some diseases that can cause dry coughs, allergies can also cause children to cough constantly. So let’s immediately understand why children keep having dry coughs.

1. Children are neither afraid of cold nor heat (applicable in autumn and winter). Appropriate temperature and humidity are important factors in keeping children's respiratory tract clean. When the indoor temperature is too high and the humidity is too low, the child's respiratory cilia movement function will be greatly reduced, and the ability of the respiratory tract to resist germs will be reduced. The child will be repeatedly attacked by germs, the respiratory tract lining will be damaged, and the child's cough will not heal for a long time. For children, the most suitable indoor temperature is 18-22 degrees.

2. Improve the dry environment (applicable in autumn and winter). Viruses and bacteria are often attached to floating dust that is several times larger than themselves. Dry air causes dust to fly, allowing the carried germs to be inhaled into children's respiratory tract, causing respiratory infections. Experts and scholars have obtained quantitative data: suitable environmental humidity can effectively inhibit the survival of influenza virus. When the environmental humidity is lower than 35%, the survival time of influenza virus exceeds 24 hours; when the environmental humidity is higher than 50%, the survival time of influenza virus does not exceed 10 hours. Therefore, as long as the environmental humidity is appropriately increased and controlled above 50%, the survival of influenza viruses can be effectively inhibited and virus invasion can be prevented. There are many ways to humidify the air, but the most scientific way is to use an air humidifier.

3. The temperature difference in the room should not be too large (applicable in autumn and winter). The temperature in your child's room should be consistent with that in other rooms. The cold air from other rooms will not enter the child's room when the door is opened. When the indoor temperature is too high, the pores all over the body are in an open state; when encountering air conditioning, children's pores cannot shrink as quickly as adults to block the invasion of cold wind. Lacking protection, viruses and bacteria will take advantage of the opportunity to enter.

If your child keeps coughing while sleeping at night, you can raise his head a little bit, and the coughing symptoms will be significantly relieved. Elevating your head can help relieve coughs caused by many reasons. So you can take your children outdoors to exercise more often.
