Why are my fingers blue and cold?

If you happen to look at your fingers and notice that they have turned an eerie shade of blue, don’t worry; you’re not becoming a Smurf. It’s possible for your fingers to appear blue if they are cold or if there’s an underlying health condition. However, fret not as I will be taking you through the reasons why this could be happening.

What causes my fingers to turn blue?

There are lots of different reasons why your fingers might start looking positively frosty. Some people naturally have colder hands than others, but it can also signify other issues such as:

Raynaud’s Disease

This is a disorder where blood vessels in the extremities like toes or even fingertips spasm when exposed to cold temperatures causing them to become pale, then blue before turning red.


Hashimoto’s Thyroiditis results from underactive thyroid gland inadequately secreting hormones responsible for maintaining body temperature regulation among other functions.


When skin advances beyond its protective mechanism in frigid environments it can lead tissue injury due to freezing conditions known casually as “frostbite”.

How do these conditions contribute?

Aside from changing colors on the tips of our digits how does each affected part mentioned earlier cause our palms reach arctic-like temperatures? Allow me demystify some medical jargon (that doctors usually love throwing around) used along with these conditions:

Decreased peripheral vascular resistance
A cluster of symptoms arising from overactivity from alpha2- receptors creating lack of blood flow resulting in feeling frozen solid

Reduced thermoregulation
Hypothalamus fails regulate heat loss frequently because who doesn’t want warmest toes?

Bodily tissues decreased metabolism
Observed imbalance fuel rates leads cellular respiration levels down reducing thermal energy expenditure thereby decreasing ability maintain warmth during normal activity/low external temperatures

What other symptoms should I look out for?

It’s fairly common to only notice the fingers being affected but sometimes there are additional indicators which suggest a more serious issue. Take note if you:

Experience headache, confusion or drowsiness

These might be due to low oxygen levels in your body resulting from reduced circulation from blood.

Shortness of breath and chest pain

Worth noting that an overworked heart beat faster leading worsened symptoms with blue limbs stemming specifically from each individual condition outlined earlier.

Worsening color change & Pain

Applying heat is recommended when extremities blue excessively/becoming painful (likely blocking adequate blood) while immediate medical attention required if accompanied by shortness of breath or lightheadedness.

How can I prevent it?

We now know what conditions cause our hands and feet develop freezing temperatures so let’s explore how we can fight these tendencies.

Dressing warmly limits amount time vulnerable areas exposed to cold air ensuring stable temperatures within your body as well reducing risk frostbite developing toes/fingers.

Exercise regularly
Impaired circulation mostly caused by inactive lifestyle due lack regular activity hence physical exercise improves circulatory functioning over time further improving overall temperature regulation process specific variations per affected part mentioned above.

Fluid Intake
Staying hydrated maintains good hydration leads to much better sweating rates effectively lowering chances hand becoming “snowflakes” especially during high heat/humidity periods

Other considerations:

I cannot emphasize enough on proper health care maintenance through consulting practitioners in case of any unusual discolorations noted anywhere else besides just fingertips/toes irrespective whether joined onset Raynaud’s disease along with thyroid disorders respectively. Always seek professional advice before indulging into home remedies as this could lead exacerbation owing unclear causative factors involved.

Lastly, ensure that hands are kept moisturized frequently given harsh weather/gloves usage yet another preventive measure against “Elsa-like” symptoms which doesn’t hurt to keep one warm – unless it’s overdone and we end up frying like festive turkeys.


In conclusion, being aware of possible causes towards freezing palms helps identification therefore allows for appropriate measures taken either preventative or medically in view of severity. With all said and done now you can face winter storms & Christmas shopping marathons with confidence without fear turning into a frosty snowman/ghost bride/Zombie Santa (although those could make great Halloween costume ideas 😉)!
