Answer:
Raynaud’s disease (also called Raynaud’s phenomenon or Raynaud’s syndrome) occurs when the blood vessels in the hands and feet constrict in an overactive response to cool temperatures. People with Raynaud’s have extra sensitive blood vessels that become more narrow than normal, causing their hands and feet to feel temporarily cold and numb. It may happen during the winter time, or even in an air conditioned room. It can take 15 minutes for normal blood flow to return after warming.
There are two types of Raynaud’s: primary and secondary.
Primary Raynaud’s is the most common version (90% of those with symptoms) and isn’t linked to any underlying issues. Although people might experience discomfort while their fingers are numb and cold, it’s fairly harmless. Doctors haven’t identified any particular reason why this happens.
Secondary Raynaud’s signifies there is a link between these symptoms and another medical condition – usually an autoimmune disease like lupus or rheumatoid arthritis. It can also be caused by other secondary factors, such as taking certain medications, smoking, frostbite or jobs with repetitive motion or vibration.

Devoting ourselves to improving other people lives gives us that satisfaction and the drive to keep going.
