As soon as the weather gets cold, my girlfriend's hands and feet get cold. Is there any way to improve it? thank you

This is to prevent wearing clothes, mainly to protect women's neck, shoulders, stomach, feet and calves. Don't cut down on clothes when the weather improves slightly, it's easy to catch a cold. You can wear a scarf and coat when you go out, don't wear stockings often, and sleep with a quilt at night. I suggest you buy a long quilt, eat as little cold food as possible, exercise regularly after meals and eat high-calorie food, but it is not easy to eat it all.
