Introduction
A child’s normal (baseline) body temperature ranges from 36.9°C to 37.4°C. Fever is generally defined as a body temperature exceeding the baseline by more than 1°C. Hypothermia is defined as a body temperature below 36°C. A mild elevation in body temperature in young children is not necessarily abnormal; not all temperature elevations constitute fever. If a young child develops a fever, the first priority is to ensure adequate fluid intake, followed by supplementation with various essential nutrients.
A child’s normal (baseline) body temperature ranges from 36.9°C to 37.4°C.
Fever is generally defined as a body temperature elevated by more than 1°C above the baseline. Hypothermia is diagnosed when the body temperature falls below 36°C. Infants and young children are particularly prone to hypothermia because their thermoregulatory center is not yet fully developed and their relatively thin subcutaneous fat layer facilitates rapid heat loss.
Infants with hypothermia typically exhibit characteristic symptoms, including weak crying, refusal to feed, cold skin, hypoglycemia, and sometimes indurated (firm, swollen) areas in the subcutaneous fat tissue. If left untreated, hypothermia can lead to generalized weakness, impaired immunity, and—severely—may even endanger life.
It is important to note that an elevated body temperature in infants and young children does not necessarily indicate pathology; not all temperature elevations constitute fever. Brief, transient fluctuations in body temperature—especially when accompanied by otherwise good general health and absence of other abnormal signs—should not be interpreted as fever.
If an infant or young child develops a fever, ensure adequate fluid intake first, followed by appropriate nutritional support. If the fever persists, prompt medical evaluation is essential.
