A sore throat is a very common childhood illness, mostly caused by respiratory infections or excessive use of the voice. A sore throat caused by excessive use of the voice can be cured by resting well, drinking more warm water, and talking less. Children’s sore throats may also be caused by the following: 1. Viral or bacterial infections: Children’s immunity is not fully developed and can easily be combined with viral and bacterial infections, resulting in upper respiratory infections, including influenza, pharyngitis, tonsillitis, laryngitis, etc. These symptoms can lead to sore throats. Parents should pay attention to their children’s living environment, don’t take them to crowded places, wash their hands regularly, pay attention to hygiene, open windows and ventilation often, and exercise to strengthen their resistance. 2, outside environmental stimulation: some children’s physique is poor, the stimulation of cold air will also lead to children’s sore throat phenomenon, and some areas with serious air pollution, the phenomenon of sore throat will also occur. So pay attention to keep warm in time when the weather changes and don’t let children go to places with serious pollution. 3. Excessive use of voice: Many children like to shout. Long-time loud shouting will cause the vocal cords to vibrate too high, thus making the voice stimulated and start to hurt. So don’t let your child shout a lot to avoid damaging the voice and vocal cords. Finally, although children’s sore throat is not a major disease, it should be given enough attention by parents to avoid delaying the seriousness of the condition. Parents can give their children more nutrition in their daily life to strengthen their resistance against viruses or bacteria, so as to reduce the phenomenon of children’s sore throat.
