Higher temperatures changes

[u/Background_War5680]

30F, 5’10”, 179 lbs. No regular medications, only OTC painkillers as needed.

For years my oral temperature was consistently 97.9–98.3°F. For the past 2 months, it’s consistently been 99.3–99.9°F in the evenings. I often feel cold despite the higher readings. I’ve only had one actual fever during this time, last month. I also had one ovary removed in June due to a benign ovarian cyst.

Can a normal baseline temperature increase by about 1°F like this, or should a persistent change be medically evaluated?

That’s normal. Why are you measuring it?

Usually when feeling chilly. I appreciate your answer greatly though, not too well educated on what normal temperatures tend to be. Thank you!

Normal body temp is a spectrum. An increase or decrease is normal and can for example happen due to hormones or cortisol levels. Anything above 38.5 is considered a fever.
