Puberty is the normal physical process of transition from childhood to adulthood.
As well as a time of multiple physical changes, puberty is also a time of significant emotional and social change. Puberty heralds a period of brain development only matched by that during infancy.
The emotional brain, or ‘limbic system’, develops first, and the ‘neo-cortex’, or thinking brain, develops last. This means that the capacity to reason, regulate emotions and control impulses may be a conflicting process for teens.
All of this brain development means that those going through puberty may be acutely sensitive to their environment and its stressors, meaning that puberty can be a time of often overwhelming emotional experience.
