A fever of 37.9 degrees in an adult can be a sign of a mild fever. A fever is usually defined as an increase in body temperature above the normal limit, which is around 36.1-37.2 degrees. In adults, fever usually starts when the body temperature rises above 38 degrees. In this article, we look at what a temperature of 37.9 degrees means for an adult and when it can be a cause for concern.

What is normal body temperature?

Normal body temperature varies from individual to individual and can depend on many factors, such as time of day, physical activity and measurement method. In general, a normal body temperature is around 36.1-37.2 degrees. The temperature may be slightly higher in the afternoon and evening and after physical exertion.

What does 37.9 degrees mean?

37.9 degrees is a slightly higher temperature than normal, but it does not yet meet the criteria for a fever, which usually starts at 38 degrees. However, this temperature can be a sign that the body is fighting an infection or reacting to some other stimulus.

Possible reasons for a slight increase in temperature

  • Infections: The most common cause of a slight increase in temperature is an infection, such as the flu or another viral infection.
  • Stress: Physical or mental stress can raise body temperature.
  • Physical activity: Heavy exercise can temporarily increase body temperature.
  • Environmental factors: Hot weather or high humidity can also raise body temperature.

When to see a doctor?

Although 37.9 degrees is usually not a cause for concern, there are some situations in which it is good to see a doctor:

  1. If the temperature rises above 38 degrees.
  2. If the fever lasts more than three days.
  3. If the fever is accompanied by other serious symptoms, such as severe headache, chest pain, breathing difficulties or confusion.
  4. If you have a weakened immune system or any chronic disease.

Summary

37.9 degrees in an adult is usually not a cause for concern, but it can be a sign of a mild infection or other temporary condition. It is important to monitor the symptoms and see a doctor if the situation worsens or the fever persists for a long time.
