What you describe is unusual as I have never heard similar stories before.
Surely enough, the body will warm up significantly after (as well as
during) a workout session. That, as a matter of fact, is the reason why you
are likely to sweat following a workout, even after showering. The body
exerts its heat which accumulates due to high activity inside the muscles.
Likewise, if you are unused to working out on a regular basis, your muscles
will be affected for longer periods of time. You might expect them to make
you feel warmer.
More points to ponder: are you eating differently? Has the weather or
clothing changed? Have you been exposed to the sun more often then before?
The body repearing itself is a process that, in my opinion, will not
release much thermal energy. Soreness is more likely to be a cause for
