Daytime body temperature: Adrenal issue?

As I understand it (or not) your body temperature is coolest in the early morning and peaks in the early evening. If that is correct, should I read anything into the fact that the reverse is the case for me? I'm a full degree or so cooler in the evening than the morning.

Is this also normal, or is there something I might want to investigate? I often see people referring to their temperature in relation to possible adrenal issues so it did make me wonder.

  • It can indeed indicate an adrenal issue. Does your energy slump mid afternoon?

  • I have noticed that sometimes, yes. And I thought it was odd since I'm on a lowish carb diet so a post-sugar high crash couldn't be the culprit...

  • Yes I have found this get hot in the eve but central heating dosnt help either.

  • This is an explanation and the temp is taken on awakening before one gets out of bed. This is called the Basal Temperature Test and why it can be helpful:_

    "Basal body temperature is the lowest body temperature attained during rest (usually during sleep). It is generally measured immediately after awakening and before any physical activity has been undertaken, although the temperature measured at that time is somewhat higher than the true basal body temperature (see Fig. 1). In women, ovulation causes an increase of one-half to one degree Fahrenheit (one-quarter to one-half degree Celsius) in basal body temperature (BBT); monitoring of BBTs is one way of estimating the day of ovulation."

    It is usual when hypothyroid that our temperature is lower than average until we get to an optimum of medication but sometimes it doesn't come back to normal.

  • I have measured my temperature before getting out of bed, result usually around 37.4, but wondered whether a bloody great duvet and electric blanket would skew the result. In any case I feel colder in the evening and have recorded temperatures of 36.3 or so. Not as cold as some, but enough to give me odd facial chills...

  • I think our body has to regulate our temp, i.e. on a boiling hot day we sweat to keep our body at a particular temp (or even under a duvet). If we have an infection, temp rises to kill virus. That's why it's important to have as near a normal temp as possible and why some hypo complain constantly of cold at their very core till on optimum meds.

  • If you wanted to know for sure re the adrenal function you could get a 24 hour saliva test done (Genova diganostics), details through Thyroid UK's website. Or you could try doing the Dr. Rind's metabolic temperature chart:

    Or just go ahead and trial some adrenal support supplement e.g. Nutri Adrenal or Nutri Adrenal Extra or Thorne's Cortex. The Nutri Adrenal Extra might be a good one to try first, as it not only has some adrenal glandular in it but multi vits & mins also to support these glands.
