Raynaud’s disease is when the small arteries that circulate blood in the extremities, such as the hands and feet, become narrow due to vapospasms. Vapospasms are contractions that can occur due to stress or cold temperatures. The result is the affected areas feeling numb and cold as a result of the restricted blood circulation. It most commonly affects women and those living in cold climates. Raynaud’s disease usually does not involve treatment, aside from exercising to maintain good circulation and keeping warm with thick gloves and socks in cold weather. There are medications available to treat the disease if symptoms worsen.
