I feel it’s a myth.Fever can be caused by Autoimmune disorders,post vaccinations ,excessive heat or heat stroke ,Some medications like anti-seizures,anti depressants.

My opinion is that it’s a myth too. Raise in body temperature can be due to variety of reasons. Maybe the severity may vary.

Nice @Kavishri17 .When you say “stress or more”, what specific physiological mechanisms are you referring to (e.g., cytokine release, hypothalamic set-point change)?
You mention autoimmune disorders — which specific conditions do you think are most commonly associated with fever without infection?
I agree it’s a myth. A rise in body temperature can occur due to multiple non-infectious causes, though severity and pattern may vary. How do others differentiate infectious from non-infectious fever in clinical practice?
Like Systemic lupus erythematosus,Rheumatoid Arthritis.I read that the auto inflammatory diseases rather than autoimmune disorders cause such fevers without infection.

It depends on the associated symptoms and signs. Also history from the patient. Blood tests can give additional information too.

Yes ,It does mean all type of stress like neuro-endocrine , triggering of pro inflammatory cytokines , thermoregulatory set points and all.

Fever is a helpful warning signal, not an enemy. Panic and over-medicating are bigger problems than fever itself. Respect it, monitor it, and treat wisely.

Fever is not only occur when there is an infection or any microorganisms enters in our body. Iy is also occur due to abnormal processes.
When there’s inflammation, medication etc.

Fevers are classified into five main types: intermittent, remittent, hectic, continuous, and relapsing, based on temperature pattern and duration. Fever is a symptom, not a disease, and is commonly associated with chills, headache, body aches, fatigue, and loss of appetite. Infections are the most common cause, but fever may also result from inflammation, drugs, hormonal disorders, environmental heat, or cancer. High or prolonged fever with severe symptoms requires medical attention, while most fevers resolve with fluids, rest, light food, and antipyretics.

In your view, what red‑flag symptoms or thresholds warrant immediate medical evaluation vs watchful monitoring at home? 
Do you think the pattern of temperature change (like remittent vs continuous) helps narrow down causes clinically? 
Which type of fever pattern do you find most clinically challenging to interpret, and why?

Yes, it does continuous temperature change can be associated to UTIs and typhoid fever.
And remittent change can associated to respiratory infections
