Breastfeeding has many benefits. The latest research shows that breastfeeding children are more adaptable to the outside world. Studies have shown that breastfeeding children aged 0 to 1 years have higher cortisol levels in their saliva than children of the same age fed formulas. Speaking of cortisol, people may not be familiar with it. Cortisol, also known as "cortisone" or "hydrocortisone", is a hormone produced by the human adrenal glands in response to stress.

　　Cortisol is important in infancy Role: Participate in the formation of the HPA axis, and can affect the body''s responsiveness to stress. Studies have shown that breastfeeding children aged 0 to 1 years have higher levels of cortisol in their saliva, which may affect the individual''s ability to respond to stress and adapt to development.

How do hormones pass from mother to child? Studies have shown that the concentration of cortisol in the mother is related to the concentration of cortisol in breast milk, and during breastfeeding, the concentration of cortisol in the mother’s serum is Was dropped. The researchers speculate that this is due to the transfer of the mother’s cortisol into the child’s body through breast milk.

　　Cortisol is an indispensable hormone of the human body. When the human body is under stress, the body needs cortisol to maintain normal physiological functions; without cortisol, the body will not be able to respond effectively to stress. Because cortisol secretion releases amino acids (from muscle), glucose (from liver), and fatty acids (from adipose tissue), these are transported into the blood for energy use.

　　Cortisol has a particularly important effect in manipulating emotions and health, immune cells and inflammation, blood vessels and blood pressure, and maintaining connective tissues (such as bones, muscles, and skin). Under stress, cortisol generally maintains blood pressure stability and controls excessive inflammation.

　　 Therefore, children who eat breast milk, the hormones from the mother have a good stimulating effect on the child, so that the child has a stronger adaptability to the outside world. And this hormone from the mother is harmless to the child, which is completely different from the hormone directly ingested from the outside world (direct intake requires the use of hormones, there are many side effects.) This is another magical function of breast milk.

　　The relationship between infant feeding methods and cortisol content

　　Some studies have shown that breastfeeding children aged 0~1 years have a higher cortisol content in saliva than children of the same age fed formula #xFF05;.

　　 Previous studies have shown that maternal cortisol concentration is correlated with breast milk cortisol concentration (studies have shown p < 0.001), and during breastfeeding, the concentration of cortisol in the maternal serum has decreased. The researchers speculate that this is due to the transfer of the mother’s cortisol into the child’s body through breast milk.

　　Cortisol plays an important role in infancy: it participates in the formation of the HPA axis and can affect the body’s responsiveness to stress. Breastfeeding children aged 0 to 1 years have higher levels of cortisol in their saliva, which may affect the individual’s ability to respond to stress and adapt to development.

Cortisol, also known as "cortisone" or "hydrocortisone", is a hormone-like hormone produced by the adrenal glands in response to stress. C24H30O5, 11β, 17α, 21-trihydroxy-4-pregnen-3, 20-dione. Also known as hydrocorticoid or compound F (compoundF). It is extracted from the adrenal cortex that has the strongest effect on carbohydrate metabolism. It is produced by 11-deoxycortisol through the action of 11β-hydroxylase in the mitochondria of the adrenal cortex. Cortisol can also pass 11-β-hydroxysteroid dehydrogenase (11-β-hydroxysteroid dehydrogena-se) becomes corticosteroids.

　　Stress requires cortisol to maintain normal physiological function; without cortisol, the body will not be able to respond effectively to stress. Because cortisol secretion can release amino acids (from muscle), glucose (from liver) and fatty acids (from adipose tissue, these are transported into the blood for energy use.

　　Cortisol is used to manipulate emotions, health and immunity The connection between cells and inflammation, blood vessels and blood pressure, and the maintenance of connective tissues (such as bones, muscles, and skin) have particularly important effects. Under stress, cortisol generally maintains blood pressure stability and controls excessive inflammation.
