Is it normal to never run a fever?
Yep.Totally normal
Yes, it can be normal to rarely or never notice a fever. Not every infection causes one, and people’s temperature responses vary.
Some people just don’t seem to run fevers often. You may also have had mild illnesses that didn’t cause a noticeable temperature, or not checked your temperature at the time.
A fever is one possible response to illness, not a requirement—and never having one doesn’t mean you never get sick or that your immune system is unusually strong. Pay attention to how you feel overall, not just the thermometer.
