Fever is a healthy biological response, it acts as a natural defense mechanism, boosting immune function and hampering the growth of many pathogens. For most infections, especially mild ones, letting a low-grade fever run its course is often beneficial, and simple comfort measures like light clothing, hydration, and tepid compresses can help manage symptoms without interfering with the body’s response. If a pregnant woman has a prolonged high fever above 39c, then you gotta a bigger problem that paracetamol alone won't resolve.
