I understand that you are well aware of the term Puberty. Now, it’s time to discuss more Adolescence. Let’s begin, shall we?

Introduction to the term “Adolescence”.

The meaning of Adolescence is to grow up. It is a Latin word derived from, Adolescere. Basically, the definition of Adolescence is the age of transformation that happens during Puberty. Adolescence is the step towards Adulthood. It leads to the physical and mental in the human body.

To achieve Adulthood, it is important to understand that the changes occur in the human body. Adolescence affects one’s body as well as mind. At the right time, the human body starts releasing hormones that work in a rhythm with organs to achieve physical maturity. Therefore, due to the highest level of Hormones in the human body, Children’s behaviour seems on the top between the ages of 16-19. In their early years, a typical teenager has lots of mood swings. Therefore, it is not time to get mad at them. You need to deal with care and love. Always remember, patience is what you need during these years. Try to help them with what they are going through.

These hormones both transform the mind and body both. The emotions of teenagers are uncontrollable during Adolescence. Males exhibit more emotional behaviour of anger than females. The boys gain muscle strength and become unstoppable due to millions of emotions. 

However, females become mature at a very early age than males. Also, girls start growing and go through changes earlier in the age we call “Preadolescent age”. Therefore, females achieve Adulthood at the speed of light. However, it is quite the opposite when it comes to males. The male bodies take their time to go through the changes and become mature. According to the studies, the puberty period for males is generally 16-17. However, unlike girls, they become mature at 21.
