Introduction

Low-grade fever refers to a mild fever. Having a persistent low-grade fever of 37°C for five days may be caused by physiological reasons or pathological conditions, such as colds or pneumonia, requiring targeted treatment depending on the specific cause. In addition, it could also indicate a urinary tract infection. If symptoms continue to worsen, it is important to seek timely medical evaluation at a hospital for proper diagnosis and treatment.

Low fever refers to a mild elevation in body temperature. A persistent low-grade fever of 37°C for five days may result from either physiological or pathological causes, such as the common cold or pneumonia. Treatment should be based on the underlying cause.

I. Physiological Causes

A continuous low-grade fever of 37°C for five days may occur when a woman is in her ovulation phase. Due to hormonal fluctuations, excessive secretion of estrogen and progesterone can affect the body's temperature regulation center, leading to a temporary rise in body temperature. This is a normal physiological phenomenon. During ovulation, it is important to get adequate rest and drink plenty of warm water. Specific medical treatment is usually not required.

II. Pathological Causes

1. Common Cold

When the body is exposed to cold or infected with a virus, it may develop a common cold. Symptoms include nasal congestion, sneezing, and sore throat. The body's temperature regulation center may be stimulated, resulting in a persistent low-grade fever of 37°C for five days. Under a doctor’s guidance, medications such as azithromycin tablets or Shuanghuanglian oral liquid may be used for treatment.

2. Pneumonia

In individuals with weakened immunity, invasion of pathogens into the respiratory tract may lead to pneumonia, which can cause prolonged coughing and a continuous low-grade fever of 37°C for five days. Under a doctor’s guidance, medications such as levofloxacin tablets or azithromycin tablets may be prescribed for treatment.

Besides the above, a urinary tract infection could also be a possible cause. If symptoms persist or worsen, prompt medical evaluation at a hospital is recommended for proper diagnosis and treatment.

Why does the temperature rise to 37°C every night?

A body temperature of 37°C at night may be a normal phenomenon, as body temperature naturally fluctuates throughout the day. After eating in the evening or being in a warm environment, body temperature may rise to around 37°C. However, pathological causes such as pneumonia, tuberculosis, or lung tumors cannot be ruled out. It is recommended to seek medical attention at a hospital promptly for diagnosis and appropriate treatment based on the underlying cause.

Is a body temperature of 37 degrees measured by an infrared thermometer normal?

A body temperature reading of 37 degrees from a thermometer gun refers to 37°C, which is generally considered normal. The normal human body temperature ranges from 36.1°C to 37.2°C, with 37°C being the upper limit of normal. Therefore, if a thermometer gun measures a body temperature between 36.1°C and 37.2°C, it can be regarded as within the normal range. If the temperature exceeds 37.2°C, it may indicate that the body is experiencing fever.

Is a body temperature of 37°C considered a fever in an 8-year-old child?

37 degrees generally refers to 37°C. Fever means an elevated body temperature, specifically when it exceeds the normal range. A temperature of 37°C in an 8-year-old child falls within the normal range and usually does not indicate fever, so there is typically no need for concern. Body temperature is generally measured under the armpit, with a normal range of 36.1°C to 37°C. The normal body temperature for an 8-year-old child is typically the same as that of an adult.
