Question

I am from 6th class I want answer to this question while running our cheeks get Red but not legs why

Answer 1

hi,

Whenever there is more blood flow to an area of skin (such as your cheeks), the blood vessels enlarge to compensate. ... Facial flushing is usually more of asocial worry than a medical concern.

Answer 2

Due to lack of water our cheeks get red but due to lack of oxygen lactic acid is produced in muscles of legs.
Also you know breathing during time of running makes our mouth cool and dry.
