Introduction
Fever refers to an elevated body temperature. Generally speaking, when the body temperature reaches 39°C, fever patches have limited effectiveness, and timely medical attention should be sought to avoid adverse effects. A temperature of 39°C is considered a high fever; at this level, fever patches are likely insufficient and may fail to reduce the fever. Prolonged high fever can lead to dehydration and, in severe cases, may cause febrile seizures.
Fever refers to an elevated body temperature. Generally, when the fever reaches 39°C, the effectiveness of fever-reducing patches is limited, and timely medical attention should be sought to avoid adverse effects. The detailed analysis is as follows:
Fever-reducing patches are a form of physical cooling that work by evaporating water within the gel to draw heat away from the skin surface, thereby lowering body temperature. Fever may be caused by factors such as exposure to cold or bacterial infection, and can be accompanied by symptoms like chills and headache. A body temperature of 39°C is considered high fever; using fever-reducing patches under such conditions has limited effect and may fail to reduce the fever effectively. Prolonged high fever can lead to dehydration and, in severe cases, febrile seizures. Under a doctor's guidance, patients may take medications such as ibuprofen sustained-release capsules, acetaminophen tablets, or aspirin tablets to achieve fever reduction.
In daily life, it is important to get adequate rest, ensure sufficient sleep, avoid staying up late, and engage in moderate outdoor activities such as walking or jogging, which can help promote recovery.
