Always plan ahead. Cold temperatures are a main cause of raynaud's phenomenon, so cold weather can trigger symptoms. If a person has only mild symptoms, he can keep his hands, feet, face, and ears warm with well-insulated clothing. Gadgets such as heated gloves and heated socks from winter sports stores may help. Never getting lost, using portable heaters, pre-warming the car, keeping dry, etc..., are helpful ideas.
Keep warm. Wearing warm gloves and shoes will help. For severe symptoms, taking vasodilator drugs or even moving to a warmer climate for the winter may help. Finally, a complete physical exam and blood testing for other causes of raynaud's may also help.
