Adolescence:

Adolescence is the era between childhood and maturity, lasting from the ages of ten to nineteen. It’s a special time in human development, and it’s critical to set the groundwork for long-term health.

Adolescents develop physically, cognitively, and psychologically at a rapid rate.This has an impact on how individuals feel, think, make decisions, and interact with others.

Adolescence is marked by considerable death, disease, and destruction, despite its reputation as a healthy time of life.Much of this can be avoided or treated. Adolescents form patterns of behaviour throughout this phase, such as those linked to diet, physical exercise, substance use, and sexual activity, that can either safeguard their health and the health of others around them, or put their health at danger now and in the future.

Adolescents require information, including age-appropriate comprehensive sexuality education, opportunity to build life skills, acceptable, equitable, appropriate, and effective health services, and safe and supportive environments in order to grow and develop in good health. They also require opportunities to take an active role in the development and delivery of programmes that will help them improve and maintain their health. Expanding such possibilities is critical to meeting the unique needs and rights of teenagers.

Puberty:

Puberty is the period in a person’s life when that person either boy or girl becomes sexually mature. It generally hits in girls between the ages of 10 and 14, and in boys between the years of 12 and 16. It causes bodily changes in boys and girls and has varied impacts on them.

Puberty symptoms include:

In females:

• The first symptom of puberty is the formation of breast.
• After that, hair begins to grow in the pubic area and armpits.
• Menstruation (or a period) usually happens last.

In males:

• The testicles and penis grow larger as puberty progresses.
• After that, hair begins to grow in the pubic area and armpits.
• As puberty progresses, muscles increase, the voice deepens, and facial hair grows.

Precocious puberty

Precocious puberty is a phrase used to describe puberty that occurs much earlier than normal. Puberty is the period in a child’s life when he or she has a growth spurt and begins to develop the sexual physical characteristics of an adult.

The hypothalamus in the brain releases chemicals (hormones) that cause the pituitary gland to release gonadotropin hormones. Gonadotropins promote the formation of the sex glands (also known as gonads), which are the testicles in boys and the ovaries in girls. The testicles in boys produce testosterone, whereas the ovaries in girls produce oestrogen. Puberty strikes girls between the ages of 8 and 13, and boys between the ages of 9 and 14.

Precocious puberty affects children significantly earlier: girls develop secondary sexual traits, such as breasts, before the age of eight, and boys with precocious puberty experience changes before the age of nine.

Stages of Adolescence :

Early Adolescence  (Ages 10 to 13)

• At this age, children frequently begin to grow at a faster rate. They also observe other physical changes, such as hair growth under the arms and at the genitals, female breast development, and male testicular enlargement.
• Some people may be curious and anxious about these physical changes, especially if they are unsure of what to anticipate or what is normal.
• Adolescents’ thinking is definite and black-and-white.
• Pre-teens have a stronger desire for privacy.

Middle adolescence:

• During middle adolescence, physical changes from puberty continue.
• Many teenagers start interested in romantic and sexual interactions at this age.
• As they want  independence in their life, many middle teens have more disagreements and conflicts with their parents.
• During this stage, the brain continues to evolve and mature, but there are still numerous distinctions between how a normal middle teenager thinks and how an adult thinks.

 Late Adolescents (18-21 years old and up)

Movement Toward Independence

• A stronger sense of self
•  The ability to postpone gratification

Differences between adolescence and puberty:

Conclusion :

The beginning of adolescence is closely correlated with the onset of puberty, which results in significant changes in hormone levels as well as a range of physical changes as a result of these changes.

Biological growth and development, an undefined position, greater decision-making, increasing demands, and the search for self are the five main features of adolescence.
