Why is the tip of my nose always cold?

A cold nose tip has many possible causes, including hypothyroidism, cold weather, the aging process, seasonal affective disorder and certain viral infections, according to Right Diagnosis. A cold nose, especially when accompanied by cold toes, may be connected to menopause and is often associated with the rebound effect of dilated blood vessels that precedes hot flashes.

Hypothyroidism should be ruled out when a cold nose is experienced along with being tired and having diminished concentration. Having a cold nose may also be the result of a subnormal body temperature, which when accompanied with chills, can indicate the presence of the common cold, according to the University of Oregon.
