Introduction
Bloodletting is a traditional therapy that, in theory, may provide temporary relief for certain heat-related conditions. However, modern medicine has confirmed that fever is mostly caused by infections or immune responses. Bloodletting cannot eliminate the underlying cause nor effectively reduce body temperature, and may instead delay proper medical treatment. For fevers caused by bacterial or viral infections, targeted anti-infective medications are required, whereas bloodletting has no actual therapeutic value.
Generally speaking, bloodletting for fever has no clear therapeutic effect and may pose health risks; self-administered procedures are not recommended. If you have concerns, it is advisable to seek medical advice promptly. Detailed analysis is as follows:
Bloodletting is a traditional therapy that theoretically might provide temporary relief for certain heat-related conditions. However, modern medicine confirms that fever is mostly caused by infections or immune responses. Bloodletting cannot eliminate the underlying cause nor effectively reduce body temperature, and may delay proper medical treatment. For fevers caused by bacterial or viral infections, targeted anti-infective medications are required—bloodletting offers no actual therapeutic benefit.
Self-administered bloodletting carries numerous risks. Improper procedures may lead to skin damage, infection, and even serious complications such as anemia or shock. Particularly in children, elderly individuals, or those with weak constitutions, bloodletting may increase physical stress and impair recovery. Furthermore, fever can sometimes be a warning sign of severe illness; blindly resorting to bloodletting may mask symptoms and delay diagnosis—such situations must be strictly avoided.
When experiencing fever, priority should be given to physical cooling methods or taking antipyretic medications as directed by a physician. It is essential to seek timely medical care to identify the underlying cause and receive appropriate treatment. Do not believe in bloodletting therapies without evidence. If persistent high fever or severe symptoms such as intense pain occur, immediate medical attention at a hospital is necessary.
