It’s typical to get cold hands during the chilly seasons, but icy hands 24/7 are not a good sign. Cleveland Clinic says “cold hands are often the result of a lack of blood flow to the extremities.”

Sometimes cold hands are a normal response to frigid temperatures or sickness such as a fever, since our bodies need to conserve heat. However, consistently cold hands can be a sign of thyroid issues, anemia, and a condition called the Raynaud phenomenon, or Raynaud's.

Raynaud’s makes your blood vessels constrict excessively, leading to cold hands and a blue tint under your nail beds. According to Mayo Clinic, Raynaud’s can be genetic, but there are other causes to consider, such as chronic stress or other conditions like lupus, making it important to check with a doctor.
