Moreover, toes, knees, shoulders and fingers belong to joint areas with more exercise, because there are relatively few fat and blood vessels, and heat is easily lost. * When blood sugar is too low or blood pressure is low, food is an important source of heat for the body.

Carrots can be warmed by daily complementary foods, such as walnuts, sesame seeds, pine nuts and other nuts. Vegetables such as leeks, carrots, kale, spinach, etc. ; Fruits, such as apricots, peaches and papaya, are the best choice.
