Wear rubber or cloth gloves for jobs around the house.
Once you get used to them, jobs like cutting and peeling vegetables are not as difficult as you might first believe them to be. If, however, the gloves (cotton ones) get wet, do take them off and let them dry before you put them on again.
Also do try to avoid direct contact with chemical cleaners, detergents and metal polishes.
Try to protect your hands from sudden changes or extremes of temperature. These are bad for circulation and give rise to chilblains.
Exercise your hands daily for suppleness. You can exercise your hands by bending fingers up and down fifteen or twenty times daily. To pep up circulation, take the fingers of one hand in the other and then gently pull each individual finger.
