Tonsils, for anatomical reasons, have bacteria in the crypt orifice for a long time, and when the body’s immunity decreases, the bacteria present in the crypt orifice become pathogenic, causing acute tonsillitis, and the acute lesions become chronic when they recur and are not healed. Children, especially those under 5 years of age, have an underdeveloped immune system, so the tonsillar tissue in the throat becomes the key first line of immune defense. Once immunity is low, bacteria invade the tonsils and inflammation occurs, causing fever, cough, sore throat and other symptoms. Almost every baby has experienced tonsillitis, and some have recurring episodes several times a year, causing parents a lot of headaches. In winter, when the climate is cold, the chances of getting tonsillitis increase a lot more, so here are some small ways for parents to prevent tonsillitis in winter for reference. 1, keep the air flowing winter cold, parents are afraid of children freezing cold, home to close the doors and windows, and some even almost do not take children out, this approach is not right. In winter, although cold air is prevalent, it is still necessary to open the windows moderately between about 10 am and 3-4 pm on a windy day to circulate indoor air and prevent the proliferation of bacteria and viruses. Or take your child outdoors to adapt to the warm and cold weather. As far as possible, you should minimize taking your children to densely populated public places, such as shopping malls and supermarkets. 2, pay attention to the development of good eating habits Most children are partial to food, especially meat, puffed food, fried food, a variety of drinks, this partial diet will lead to an imbalance in the intake of various nutrients, which will cause the body’s immunity to decline, and thus prone to tonsillitis.
