Introduction

For babies, the thermoregulatory center is not yet fully developed, so their body temperature may be influenced by various factors such as clothing and activity levels. Under normal circumstances, a baby's axillary (underarm) temperature typically ranges between 36°C and 37.2°C. Maintaining good hygiene habits and paying attention to your baby's daily behavior can help detect health issues early.

Generally, a baby's axillary temperature of 37.2°C is considered normal. The detailed analysis is as follows:

For babies, the thermoregulatory center has not yet fully matured, so their body temperature can be influenced by various factors such as ambient temperature, clothing, and physical activity. Under normal circumstances, the typical range for a baby's axillary temperature is between 36°C and 37.2°C. If the baby is at rest and there is no sweat under the armpit, a measured temperature of 37.2°C reflects the baby’s true body temperature and falls within the normal range. However, if the baby has just finished exercising, eating, or bathing, the body temperature may temporarily rise due to increased metabolic activity, resulting in a slightly higher reading. When measuring a baby's temperature, it is important to ensure the baby is calm and that the armpit is dry to obtain an accurate result. If the baby's temperature remains above the normal range or if other symptoms of discomfort appear, prompt medical attention and appropriate treatment are recommended.

Maintaining good hygiene habits and closely observing the baby’s daily behavior can help detect health issues early and ensure healthy growth and development.
