I noticed that when it's cold, I actually sweat more under the arms. No amount of antiperspirant stops it. It just gushes out like a fountain and I'm always finding myself going in the bathroom to soak it up with tissue so it does not go through my clothes. It does not help that short sleeve shirts arn't available at this time of year so any new clothes I buy are long sleeves. I sweat easily in the summer but that's a bit different considering it's hot. Is this something I should see a doctor about, or is it perhaps a known issue that I can fix myself, either change of diet, or w/e? It's +15 in my house, yet I'm sweating. I'm actually a bit cold, yet, still sweating.
