Left Hand Cold Right Hand Warm | What's Going on?

So, what does it mean when your left hand's cold, but your right arm is warm? Per the Mayo Clinic, having cold hands even when you're not in a cold environment is common. Often, having cold hands is a part of your body's natural response to regulate your body temperature and shouldn't be cause for concern.

But if you have persistently cold hands, particularly if accompanied by color changes, it could be a warning sign. For example, having cold hands could mean you have a problem with the nerves or blood circulation or a problem with tissue damage in your hands or fingers. If you are outside in extreme cold weather and you have cold hands, you should watch for warning signs of frostbite.

Other signs and symptoms to watch for when you have cold hands include:

• Cold feet or toes
• Changes to the color of the skin on your hands, such as blue or white skin
• Numbness or tingling
• Open sores or blisters
• Tightened or hardened skin

Here are the causes according to the Mayo Clinic:

Although the cause of cold hands can be as simple as being in a cold environment or your body's natural response to maintain its normal temperature, if you have ongoing problems with cold hands, there could be a number of causes. Having cold hands could signal a problem with your blood circulation or the blood vessels in your hands.

Causes of cold hands include:

1. Anemia
2. Buerger's disease
3. Diabetes
4. Frostbite
5. Lupus
6. Raynaud's disease
7. Scleroderma

But, always work with your doctor for an accurate diagnosis.
