Introduction
A temperature of 37.4°C is considered a low-grade fever. Normal body temperature ranges between 36°C and 37°C; anything above 37.3°C is classified as a fever. Patients with low-grade fevers may initially avoid taking antipyretic medication and instead focus on drinking more water, getting adequate rest, and using physical cooling methods such as cooling patches or fever-reducing stickers. If the temperature continues to rise or shows no signs of decreasing, prompt medical attention at a hospital is recommended.
A temperature of 37.4℃ is considered a low-grade fever. Normal body temperature ranges between 36℃ and 37℃; any reading above 37.3℃ is classified as fever. Patients with low-grade fever may initially avoid taking antipyretic medication and instead focus on drinking more water, resting adequately, and using physical cooling methods such as cold compresses or fever-reducing patches. If the temperature continues to rise or shows no signs of decreasing, prompt medical attention is necessary for targeted treatment under a doctor's guidance.
The reference range for body temperature varies depending on the measurement method. When measured under the armpit, the normal temperature range is 36–37℃. Low-grade fever may sometimes be physiological, occurring after eating, upon waking from sleep, during menstruation or pregnancy in women, or due to intense emotional fluctuations. These factors can temporarily elevate body temperature, but it typically returns to normal shortly afterward, which is categorized as physiological fever.
If low-grade fever is accompanied by symptoms such as generalized muscle aches, runny nose, or sneezing, it could indicate an early sign of pathological fever caused by infection. In such cases, effective fever-reducing measures should be taken promptly. First, increase fluid intake to prevent dehydration from excessive sweating during fever. Wear comfortable, sweat-absorbing clothing to aid heat dissipation. Avoid using heavy blankets or wearing excessive clothing to induce sweating, as this may lead to severe dehydration.
If body temperature continues to rise, antipyretic medications such as acetaminophen (paracetamol) or ibuprofen may be taken as directed by a healthcare provider. Additionally, further diagnostic tests are needed to identify the underlying cause, followed by targeted treatment to promote recovery.
