Skin temperature

[Graham84]

Hi I've just got the charge 4 and getting used to new features like the metric health.

I've noticed my skin temperature is between 0.7 and -2.1 F

Should I be concerned or have it checked? Or is this a normal reading of a fitbit?

Thanks

Not actual skin temp but variation from you average.

Reading from just above the chart:

"This graph shows variations in your nightly skin temperature ..."

So zero means you temp was at its average, with no indication of what your average actually is.

I have a related question. What information are we able to draw from these measurements? It doesn't seem to correlate with anything that I can discern. The number doesn't correlate with whether I feel hot or cold or my internal temperature (measured by thermometer) and wasn't higher when I had a fever. Also, is there a normal range?

I've never seen any explanation of a real use for it.  It seems to me just another piece of information Fitbit was able to gather, and you can see for yourself if it seems to correlate with anything else.  I did see something mentioned by a Fitbit employee (not the designer) that one night he had thrown off his covers, and noticed that his skin temp was lower that night, as expected and not particularly meaningful.

I could see maybe if you turn the heat up or down at night and see skin temp move accordingly, maybe you could try to correlate that with how well you slept.

Just my thoughts - nothing official.
