From reading the forum I gather a few people have low body temperatures. I myself now have a complete intolerance to cold that I never had before using finasteride. So I decided to go out and buy a thermometer to measure my own body temperature.
My result: 34.3ºC
Actually, the thermometer that i bought only went as low as 34ºC!
Normal human body temperature is around 37ºC.
I therefore think it is a good idea to see how common this is and to accumulate results in one place. This is a good objective symptom - something a doctor cannot ignore (or put down to depression!).
