Does she have fever
before her sweating? Sweating reduces the body temperature.
Is she on any medications like cough
preparations? They may cause excessive sweating
Though fever medications do not reduce the body temperature below normal, better avoid these medications if there is no fever.
Other common cause for hypothermia is hypothyroidism- reduced levels of thyroid hormone in the body.
Make sure the temperature outside is comfortable, she is adequately clothed, she eats and drinks well. Discuss this with your doctor and have her examined if needed.
Wish your daughter good health.
