My extremities get cold very easily?

Young female, no health problems. For the past year or so, my fingers and toes get cold really easily. Just sitting around in my 72 degree house, wearing socks, my fingers and toes are freezing; I'm always wearing blankets around. Whenever I am in the same environment as many other people, I am freezing while everyone else feels comfortable. I am not extremely thin, either: 5 foot 6 inches, about 128 pounds.

I talked to my doctor and she didn't say much, just suggested I take a multi-vitamin, which I have been doing.

I have looked into Raynaud's Syndrome, but I don't believe I have this because my skin never changes color nor do I ever feel tingling sensations.

Is there any solution to this, Reddit? Or am I just going to be cold everywhere I go?
