Correction: The most common cause of a fever is [infection](https://www.uofmhealth.org/health-library/hw198785). Because a fever is the body's natural response to fight off an infection, it does [not always require immediate medical attention](https://www.fda.gov/consumers/consumer-updates/when-give-kids-medicine-coughs-and-colds). For an adult, a fever is not usually a cause for concern unless it reaches 103 degrees Fahrenheit. For infants, however, any fever may be a cause for concern.

纹身能帮你保持健康？

Tattoos have existed for over 5,000 years, as seen on Ötzi the Iceman, whose preserved skin bears 61 black tattoos predating the Egyptian pyramids. Today, tattoos are not just art or identity—they can become functional tools using nanotechnology. Color-changing inks can signal sunburn risk or body temperature shifts, turning skin into a real-time health monitor. This leap promises a future where tattoos are beautiful and life-enhancing.
