Is it normal that i pull my pants up high when i'm cold?

Whenever it's cold, I like to pull my pants up high, like up to my belly button. I feel so much warmer when I'm wearing pants that cover my stomach. I'm actually doing this right now because it's cold in the house right now. But yeah, I guess it would make sense that pulling my pants up to my stomach makes me feel warmer because then there's more than half of my body covered up. It also feels kind of good to wear my pants up to my actual waist instead of sagging them on my hips. It's more comfortable this way too so that's a plus.
