Why do I feel hot and sweat without having a fever?

Generally, feeling hot and sweating without having a fever may be caused by physiological factors, or it could result from pathological conditions such as indigestion or autonomic nervous system dysfunction. The specific analysis is as follows:

I. Physiological Factors

If the weather is hot and the individual engages in intense physical activity, the body generates heat, which is then released through sweating. This does not constitute a fever and is considered a normal physiological response. Usually, no special intervention is needed—simply resting appropriately allows for recovery.

II. Pathological Factors

1. Indigestion

Consuming overly complex meals or excessive amounts of hard-to-digest food in daily diet may increase the burden on the gastrointestinal tract. When the digestive system fails to properly process ingested food, internal heat may accumulate and fail to be expelled promptly, leading to a relatively elevated body temperature. However, body temperature readings during measurement remain within the normal range. Patients may take medications such as Bifidobacterium Trilive Capsules or Lactasin Tablets under medical guidance.

2. Autonomic Nervous System Dysfunction

Long-term mental stress or high pressure can disrupt the balance between the sympathetic and parasympathetic nervous systems, resulting in various symptoms such as fatigue, sweating, and sensations of heat. Patients may be treated with medications like Mecobalamin Tablets or Oryzanol Tablets as directed by a physician.

In addition to the above conditions, this may also be associated with hyperthyroidism or diabetes. It is recommended to seek prompt medical evaluation at a hospital and receive targeted treatment from a healthcare professional.
