A low body temperature after fever subsides generally does not pose a direct danger, but it may become concerning if accompanied by other abnormal symptoms.
Low body temperature following fever reduction may be caused by medication effects, excessive heat loss due to heavy sweating during the fever-reduction process, or insufficient warmth. In most cases, the drop in body temperature is temporary, and body temperature usually gradually returns to normal once the medication is metabolized or appropriate warming measures are taken. However, if the low temperature persists after the fever has resolved and is accompanied by other symptoms such as dizziness, fatigue, or drowsiness, it could indicate underlying pathological factors, such as dysfunction of the body's temperature regulation center or endocrine system disorders. In such cases, timely medical consultation is necessary for diagnosis and treatment based on the specific condition.
After fever subsides, consult with a doctor regarding whether to discontinue fever-reducing medication to prevent further drops in body temperature. Additionally, drink plenty of water to replenish fluids and electrolytes lost through sweating. Keep the body warm by adding appropriate clothing and avoid exposure to cold. If symptoms persist or worsen, seek medical attention promptly.
