Bad HRV-status correlates with having a cold?

Hi,

I was having a 14-days period when feeling sick and having a cold (mancold:)). I did no traing during this period. I think it is very interesting to see that my Epix 2 shows this HRV-status during the period:

I think it correlates very well with how I felt. What do you think? Is it just a coincidence or is my watch this "smart"?

Thanks,

Johannes
