Anastasia Akulova, a cardiovascular surgeon, spoke about this. She noticed that if in the cold the fingers start to turn pale or blue – this is not the norm. According to the specialist, this hints at circulatory problems.
“The norm is when the fingers turn red in the cold, and then in the warmth their color is quickly restored. If there is pain, and the fingers are pale or even become “cyanotic”, then it is worth considering. Usually the color change occurs on the second and fourth toes. As a rule, fingers turn white, and then turn blue symmetrically, that is, on two hands ”– Akulova told the Russians.
