Introduction
Low fever refers to a mild increase in body temperature. A temperature below 36°C is not considered low fever, but rather low body temperature. The normal body temperature range for healthy individuals is 36.1°C to 37.2°C. When body temperature falls below 36°C, it is considered low. Low fever is defined as a body temperature between 37.3°C and 38°C, which constitutes a mild fever. When body temperature exceeds 38°C, it is classified as high fever.
Low-grade fever refers to mild fever. A body temperature below 36°C is not considered a low-grade fever, but rather indicates low body temperature.
The normal human body temperature ranges from 36.1°C to 37.2°C. When body temperature falls below 36°C, it is considered low. In contrast, low-grade fever is defined as a body temperature between 37.3°C and 38°C, which is classified as mild fever. A temperature above 38°C is considered high fever. It's important to note that body temperature can be influenced by various factors such as ambient temperature, metabolic rate, and overall physical condition. Therefore, relying solely on body temperature to determine whether someone has a fever is not entirely accurate; other symptoms should also be taken into account.
If symptoms such as fever, headache, cough, or fatigue occur, it is recommended to seek medical attention promptly. In general, low-grade fever does not require special treatment. Maintaining adequate sleep and rest helps boost the immune system and supports recovery. Body temperature can also be reduced using lukewarm sponge baths or cold compresses, but avoid using very cold water or ice directly on the skin, as this may cause skin damage. If low-grade fever is accompanied by other symptoms like headache, cough, or fatigue, medications such as acyclovir tablets or oseltamivir capsules may be taken under a doctor’s guidance.
During episodes of low-grade fever, attention should be paid to diet. Avoid spicy, greasy, and irritating foods. Instead, consume easily digestible, nutritious foods such as vegetables, fruits, and porridge.
