For some time now I am always feeling very cold. Even throughout July and August and September my heat would be on - not always for hours but quite a long time.
Now when people visit me complain of the terrible heat and ask me to turn it off , I'm wondering am I lacking in something.
I agree with Calmck. Constantly feeling cold can be a sign of an underactive thyroid or of anaemia.
However I believe that you're diabetic. Diabetes can lead to kidney damage (diabetic nephropathy) which can also leave someone constantly feeling cold, so that's something else that your GP might want to consider.
Whatever the cause is, finding a solution will not only improve your health but also save you a lot of money on your heating bills! Get a check up!
