Newborns are afraid of cold, because fear of cold belongs to the normal physiological reaction of human beings, and also belongs to the normal protection mechanism. The child’s skin nerves are more sensitive, if parents dress the child too little, the child will appear afraid of cold, fever, nasal congestion, runny nose, sneezing and other symptoms, and even diarrhea, the newborn will have cold hands and feet, crying and restless, parents should give the child timely warm treatment. Newborns have very little subcutaneous fat and poor tolerance for cold stimuli, so parents should give their children warm treatment in time, otherwise it will lead to neonatal cold syndrome and also neonatal sclerosis, so newborns will be afraid of cold. Parents should pay attention to the child’s warmth, especially in the cold winter.
