I started running again about a month ago. (It sounds so awesome to "say" that out loud!). Anyway, I've noticed that during normal, everyday activities, I get hot and sweaty, where I didn't before. I noticed it mostly when I'm cleaning the house. For example, it happened last night when I was vacuuming and picking up around the house - nothing too strenuous. I don't remember sweating like that when I cleaned the house before I started back to running. I wasn't winded, just sweaty and hot, like I had worked out lightly. Of course, I get sweaty during my c25k runs, and no more than expected, but it's the everyday stuff that has me concerned. Maybe because my body is becoming more efficient??? (I have no idea here!) Is this normal?
