Question

why our legs become fair when we wear socks for a long period of time ( 4-5 hrs )

​

Answer 1

Answer:

It is because the blood flow to our legs gets restricted and, as the blood partially gives some colour to our body and the pigments don't reach the legs properly which gives a whitish coloration to our legs.

P.S try this thing out- press any finger for 1-2 mins then you'll observe that your finger has a whitish coloration.
