Adolescence & Puberty: What It Means

Adolescence is the big “level-up” stage between childhood and adulthood — your body, brain, and social world all change.
Puberty is the body’s process of physical maturation, including growth spurts and sexual development.

Timing: What’s Normal (and Very Normal)

Puberty does not follow a single schedule. Two people can be the same age and be in totally different stages — and both can be healthy.

Body Changes (All Bodies)

Puberty changes can happen in different orders. Here are common ones — and none of them are “weird.” They’re just biology doing its job.

Brain, Emotions & Mood Swings (You’re Not “Crazy”)

During adolescence, the brain is still developing. That can mean stronger emotions, bigger reactions, and learning how to manage stress and impulses.
This is also when identity and confidence can feel extra intense.

Hygiene & Body Odor (No Awkwardness)

Sweating and body odor can increase in puberty. That’s not “gross.” It’s glands turning on. A simple routine can make you feel comfortable and confident.

Sleep, Energy, Growth Spurts

Teens often feel sleepy later at night and struggle with early mornings. Sleep matters for mood, memory, growth, and immune health.

Body Image & Confidence (The Teen Way)

Puberty can change how you look and how you feel about your body. Social media can make it worse by showing “highlight reel” bodies that don’t represent real life.
Your job isn’t to become someone else — it’s to take care of your body and learn to respect it.

Red Flags: When to See a Clinician

Checkups, Vaccines, Privacy

Preventive care is a “future-proofing” move. A routine checkup can include growth tracking, mental health screening, sports clearance,
and vaccines. If you’re unsure about privacy, you can ask: “What can be confidential for teens in my state?”
