Why Your Body Aches When You Have a Fever
Body aches, pain, and stiffness are common symptoms accompanying a fever. Many people attribute these sensations to fatigue or lack of sleep, but medical experts explain that body pain during a fever is a natural part of the body’s infection-fighting process.
Dr. Tirta, a physician and health influencer, stated that joint and muscle pain during a fever indicates an inflammatory response within the body. This reaction isn’t harmful; it’s a sign the immune system is actively combating viruses or bacteria.
Inflammation is a complex biological response to harmful stimuli,such as pathogens. According to the National Center for Biotechnology Information, inflammation is characterized by redness, heat, swelling, and pain. These symptoms arise from the release of chemicals like cytokines and prostaglandins, which sensitize nerve endings and contribute to the feeling of discomfort.
The body’s inflammatory response isn’t limited to the site of infection.Systemic inflammation, occurring throughout the body, can cause widespread muscle and joint pain. This is because inflammatory molecules circulate in the bloodstream, affecting tissues beyond the initial infection site.
While generally not a cause for concern, persistent or severe body aches alongside a fever warrant medical attention. The Centers for Disease Control and Prevention recommends seeking medical care if a fever reaches 103°F (39.4°C) or lasts longer than three days.
