How the timing of puberty affects adolescents and young teens

Puberty begins with hormonal shifts that trigger the development of male and female sex characteristics. In general, puberty usually starts for girls between the ages of 9 and 11, and for most boys between the ages of 9½ and 13 years, although the exact age at which puberty starts varies widely among individuals.

Adolescents are usually very aware of how their development compares to that of their friends. Any development that varies significantly from the norm can be a source of great anxiety along with social and emotional struggles.

Healthy Snacks for Teens

What's the first thing you do when you get home from school? If you're like most teens, you raid the refrigerator. But snacking on the wrong foods can add unwanted calories and make you even hungrier when mealtime rolls around. Eating snacks low in nutritional value does nothing to make you smarter or stronger, either. The key is to choose healthy snacks that will fill you up and help nourish you without adding too many calories.
