What causes body aches when we’re sick?
In: 18
When you’re sick, your body produces chemicals called cytokines, which help your immune system fight off the illness. These chemicals can also cause inflammation in your body, which can lead to body aches. In addition, the infection itself can cause muscle pain and stiffness, leading to body aches. Finally, the body often becomes dehydrated when you’re sick, which can also cause muscle aches and pains.
