Why do some people say "whipped" like "hwipped"?

And some people don’t?
Like words with ‘wh’ at the beginning, some people kind of breathe a ‘h’ before the w.
Like whip would be
“hwip”
and whetstone would be
“hwetstone”

etc. It seems to me just a solid ‘w’ would be easier to say, so where has thiks little speech quirk come from? I find it quite interesting actually but where has it originated? Do you do it?
