Is a body temperature of 36.4°C normal?
Under normal circumstances, a body temperature of 36.4°C is considered normal. The detailed analysis is as follows:

In medicine, the generally accepted normal temperature range is between 36–37°C when measured under the armpit, and between 36.3–37.2°C when measured orally. Regardless of the measurement method, a body temperature of 36.4°C falls within the normal range. Therefore, if repeated temperature measurements over a period of time consistently remain around 36.4°C, and there are no symptoms such as fatigue, chills, or excessive sweating, then 36.4°C is likely within the normal temperature range. However, it should be noted that if an individual usually has a higher baseline temperature and it suddenly drops to 36.4°C accompanied by symptoms such as chills, fatigue, or dizziness, this may indicate an underlying health issue, and medical consultation is recommended.
In daily life, maintaining healthy lifestyle habits, including a balanced diet, moderate exercise, and sufficient sleep, can help support a normal body temperature and overall health.
