There is a relationship between visible blood vessels and low body fat percentage, but visible blood vessels may be related to factors such as regular body labor and relative thinness.
1. Low body fat rate: When the body fat rate is low, there is no excessive accumulation of fat in the body and relatively less subcutaneous fat, which may lead to the phenomenon of visible blood vessels.
2. Frequent physical labor: Frequent physical labor requires an increase in blood supply to the muscles and an increase in the amount of blood returning to the heart, which increases the speed of blood circulation and leads to a gradual expansion of local blood vessels and a corresponding expansion of the veins, resulting in the appearance of relatively visible blood vessels.
3. Relatively thin: the body may be too thin, resulting in a weak subcutaneous fat layer, blood vessels will also be prominent and obvious.
Low body fat rate should be kept within the normal range to avoid other adverse reactions due to low body fat rate.
