Meditation increases awareness. Energy can feel like heat or tingling or various other sensations to a person so there is a likelihood that you ae either becoming moire aware of your body becoming hot or becoming more aware of your own energy. Meditation can also raise the frequency of a person's energy and/or increase a person's energy, some people have noticed that their own temperature seems to rise as a result of meditation for these reasons as well. (I could be wrong on some points since they are based on what I read, feel free to correct me)

At any rate it is not something you should worry about but something you should explore and gain a better understanding of. If it does not affect you negatively and is a result of meditation then chances are it is beneficial or at least harmless.
