Introduction
37.2 refers to 37.2°C. Ear temperature measures the temperature inside the ear canal. Since infants have an immature thermoregulatory center, their body temperature may slightly increase or decrease by 0.1–0.2°C in response to external temperature changes. As long as an infant's ear temperature remains between 36.4°C and 38°C, it is considered within the normal range. Therefore, an ear temperature of 37.2°C in an infant is normal, and there is no need for excessive concern.

37.2 usually refers to 37.2°C. An infant's ear temperature of 37.2°C is generally considered normal.

Ear temperature refers to the temperature inside the ear canal and is one of the closest approximations of core body temperature. It is typically measured using an infrared ear thermometer, which provides quick electronic readings that are generally well-tolerated by infants. Since infants' thermoregulatory centers are not fully developed, their body temperature may fluctuate slightly with environmental changes, increasing or decreasing by about 0.1–0.2°C. As long as an infant's ear temperature remains between 36.4°C and 38°C, it is considered within the normal range. Therefore, an ear temperature of 37.2°C in an infant is typically normal and not a cause for concern.

If an infant’s temperature exceeds the normal range, parents should pay attention. For mild fever, physical cooling methods can be used. However, if high fever occurs or the fever persists, prompt medical evaluation and appropriate treatment are necessary to avoid delaying diagnosis and preventing any adverse effects on the infant’s growth and development.
