Q: During winters, while sleeping at night, the lower portion of my legs becomes very cold. This disturbs my sleep. Despite taking proper protection from cold, I still fell cold. I don't find any problem in other parts of the body. Is this a disease? What should I do to prevent this?

A:The temperature of a body part is dependent on blood circulation to that region. If you have no symptoms, this is an unlikely cause. Wash your feet before sleeping in hot water and then wear warm stockings and keep a hot water bottle at night. These steps should help.
