Do your hands change color from cold? It can be a sign of a serious illness


If we go outside in winter without gloves, we will surely see our white fingers.  This is just the normal reaction of our body to cold temperatures and our hands will return to normal after warming them up.

However, for some people these symptoms can be a sign of a more serious condition, called Raynaud's Disease, which can be harmful to health.

What is Raynaud's disease

When Raynaud's disease occurs, the arteries that supply blood to your skin become narrowed due to cold temperatures or emotional stress.  This, in turn, makes the hands, toes and sometimes other parts of the body turn white and / or blue and feel numb.  Then they turn red when the blood flow returns.  This process can also be associated with pain.  Symptoms usually last only a few seconds or minutes, but they can last up to several hours in severe cases.

Causes of Raynaud's Disease

There are 2 types of Raynaud - primary (Raynaud's disease) and secondary (Raynaud's syndrome).

The cause of the primary Raynaud is not known.  It is normal for blood vessels close to your skin to shrink when cooled.  But when people have Raynaud's disease, their blood vessels shrink more and faster than normal.  However, it is milder and more common than Raynaud's syndrome and often does not need any treatment.

On the other hand, Raynaud (Raynaud syndrome) occurs due to a underlying condition or another factor.  It is less common than Raynaud's disease, but it can cause serious health problems, such as skin wounds and gangrene.  Medications or surgery are sometimes needed for this type.

Some causes of Raynaud syndrome are:
  • Diseases and conditions that damage the arteries or nerves that control the arteries in the hands and feet (eg rheumatoid arthritis and atherosclerosis)
  • Repeated actions that damage the arteries or nerves that control the arteries (eg piano pressing or playing for long periods of time)
  • Medicine narrowing arteries
  • Exposure to certain chemicals (eg nicotine)
  • Injuries to hands or feet

Symptoms of Raynaud's Disease

Raynaud's syndrome usually affects the toes and hands, but it can also affect other parts of the body, such as the nose, ears, lips and nipples.

Due to cold temperatures or emotional stress, the arteries can shrink and shrink or cut off blood supply to certain areas.  Some symptoms are:
  • Fingers turn white and then blue
  • Feel the cold, they get numb and they can hurt
  • They turn red when blood flow returns

How can you prevent an episode of Raynaud

To prevent an attack of Raynaud's disease, try to:
  • Avoid cold temperatures and wear warm clothing, especially on the hands and feet
  • Exercise regularly, it helps improve circulation
  • Stop or limit your use of caffeine and alcohol
  • Avoid excessive pressure at your fingertips
  • Stop smoking
  • Avoid emotional stress and learn to manage it.
