Hi everyone,
I'm a 16 year old boy and I want to know how I can get accustomed to cold climates since I'm almost always cold except during spring and summer

. Will simply choosing to not put on more clothes when I feel cold help?
Here are a few possible explanations as to why I feel cold all the time, lol:
1. I'm not underweight, but I'm on the skinny side of normal weight, I'm 145 lbs and 5 foot 11.
2. I was born in Hawaii and growing up there probably did not toughen my body for the cold, moist climate of Washington state.
