Most children’s recurrent colds and coughs are caused by cold. If a child gets cold, when the condition is not serious, such as clear snot, or sneezing, or sweating is significantly reduced, this is the time when the condition is the least severe, and if it is treated at this time, the method is the simplest and most effective. Usually it is to scald the feet, keep heating the water for a while to warm up the child’s body, or drink some ginger water, or drink some decoction of perilla leaves, or wear thicker clothes, or raise the room temperature, etc. You can also use several measures at the same time, with one goal in mind, to make the child sweat a little. As long as the sweat comes out, the cold on the body surface goes out, the cold will be cured and the problem will be solved. This is the easiest way. This method is only applicable when the disease is mild. If the disease is serious, this method will not be effective, and it is time to seek medical attention.
