Adolescent children begin to face the pressure of schoolwork, after-school tutoring and staying up late to study are very common, when the refreshing caffeine drink has become one of the choices of adolescent children. However, adolescent children are in a stage of rapid development, the body is not yet fully developed, excessive caffeine intake will interfere with the child's growth.

First, caffeine may affect bone development. Bone cells can be roughly divided into two types, one is osteoblasts, which fix blood calcium in the bone, and the other is osteophagocytes, which are responsible for integrating bone calcium into blood calcium to maintain the constancy of blood calcium. However, studies have confirmed that caffeine can stimulate osteophagocytic activity. in adult studies, it has been found that bone loss occurs when calcium intake is insufficient, while calcium intake in adolescent children is generally inadequate. and adolescence needs enough calcium to build bones, and drinking coffee during this period will affect children's bone development.

Second, caffeine has the effect of activating the sympathetic nerve, resulting in a short-term increase in high blood pressure, but it has a long-term effect on growing children. The study found that adolescent children who are used to drinking caffeinated drinks such as pick-me-up drinks and coffee generally have higher blood pressure than other children who have no drinking habits, and have a significantly higher risk of developing high blood pressure in the future, which is not conducive to their cardiovascular development.

The Mayo Clinic in the United States recommends that adolescents consume no more than 100 milligrams of caffeine a day, while a medium cup of coffee from a supermarket may exceed it. Although coffee has many healthy nutrients and can be used as a refreshing drink, it may be less suitable for growing children.
