Same here. It's natural up here in the north. As your body gets cold, it constricts the blood vessels in your extremities to preserve core body temperature.
Solution? Dress warmly. Don't wear gloves, wear mittens (the kind that allows your fingers to touch inside). Don't shake hands when your hand is freezing, that is a subconscious DLV to the HB. Besides, you should be giving her a hug anyway.
You CAN use cold hands to your advantage with kino. Do the nerve-ending routine by running your cold palms over her (hopefully) warm forearm, barely grazing the skin. The sensation should send a chill down her spine
