Apply lots of Vaseline on your hands put them in a plastic bag and rub in put hands under the duvet for as long as you have it works a treat , you can use hand cream ,olive oil , coconut oil is my current favourite
It is a great thing for your feet bag on lots of cream or oil bags on then socks go to bed.
When working apply lots of hand cream then a pair of surgical gloves then your warm gloves .
I do love waterproof gloves when the weathers really tough .
