Internal fever: what é, main symptoms and what to do

Internal fever is the feeling that the person has that the body is very hot, despite the thermometer not showing an increase in temperature. In these cases, the person may have the same symptoms as in the case of a real fever, such as malaise, chills, headache, tiredness and cold sweat, but the thermometer remains at 36 to 37ºC, which is not indicative of fever.

Although the person complains that the body feels very hot, in fact, internal fever does not exist, it is just a popular way for the person to express that he has the same symptoms that are present in a common fever, but without the rise in temperature can be felt in the palm of the hand, nor proven by the thermometer. Here's how to use the thermometer correctly.

Symptoms of internal fever

Although scientifically there is no internal fever, the person may have common signs and symptoms of fever, which is when the body temperature is above 37.5ºC, the main ones being:

  • Feeling hot;
  • Cold sweat;
  • Disease;
  • Headache;
  • Tiredness;
  • Power outage;
  • Chills.

However, in the case of internal fever, although all these symptoms are present, there is no measurable rise in temperature. It is important that the person is aware of the duration of signs and symptoms and the appearance of others, as it may be necessary to go to the doctor for tests to be carried out to identify the cause of the fever and, thus, to start treatment.

Main causes

Emotional causes, such as stress and anxiety crisis, and the woman's ovulation during the fertile period are the main causes of internal fever. However, a person may also find that they have a fever after exercising or doing some type of physical exertion, such as carrying heavy bags or walking up a flight of stairs. In this case, the temperature usually returns to normal after a few minutes of rest.

At the beginning of a cold or flu, malaise, tiredness and a feeling of heaviness in the body are frequent, and sometimes people refer to a feeling of internal fever. In this case, taking a home remedy, such as hot ginger tea, can be a good way to feel better.

It is essential to observe other symptoms that may arise and that are more indicative of infection by the new coronavirus, such as dry cough, excessive tiredness, loss of taste and smell or fever. Learn about the main symptoms of the coronavirus.

If symptoms persist, go to the doctor for a physical exam to find out what may be happening. In addition to blood and urine tests, the doctor may also order a chest X-ray, for example, to check for any lung changes that could be causing this feeling of fever and discomfort.

It is advisable to seek medical help when, in addition to the sensation of internal fever, the person has other symptoms such as:

  • Persistent cough;
  • Vomiting, diarrhea;
  • Mouth sores;
  • Rapid temperature rise above 38ºC;
  • Fainting or decreased attention;
  • Bleeding from the nose, anus or vagina, with no apparent explanation.
