Numbness in a body part is typically caused by a lack of circulation, which cuts off blood supply. The body part, such as your fingers, will then begin to tingle or go numb. This is your body warning you that something is up. It is often simple to cure numb fingers, though fingers that go numb often and for long periods of time can be signs of something more serious, such as carpal tunnel or Raynaud's disease. Contact your physician if this is a reoccurring event.

Warm up your fingers. Fingers can go numb if they are too cold. If this appears to be the case with you, move to a warmer area. If this isn't possible, put your fingers under your arm pits, or the crooks of your arms or legs to generate heat.

Get moving. Poor circulation can easily be fixed by wiggling and stretching your fingers. Windmilling your arms may also help to get blood flowing.

Massage your fingers. Rubbing is another way to promote proper blood flow.
