How is it that the weather is cold and the calf itches?

The cold weather, slow circulation of blood and heat, can not supply the nutrients needed by the skin, and the skin is dry, causing itching. Proper exercise at ordinary times, speeding up blood circulation and rubbing body lotion after bathing can improve the symptoms of itchy skin. If there are red papules or white dander falling off in addition to itchy skin, it is recommended to go to the hospital dermatology department for diagnosis and symptomatic medication. Eat less spicy food in winter, eat more fruits and vegetables to supplement the vitamins your body needs, and drink more water.
