Teens Inspiring Teens: Healthy Teens, Healthy Planet

Have you ever finished a takeout meal and noticed how much plastic packaging was left behind?

And here's an even bigger question: If we're swallowing tiny plastic particles, are they actually entering our bodies?

Welcome to Healthy Teens, Healthy Planet! I'm your host, Titus Ko, from Teens Inspiring Teens, a student-led 501(c)(3) nonprofit organization.

In October 2026, researchers at Columbia University and UC Berkeley published a new study in Nature showing that microplastics in water can generate highly reactive molecules called hydroxyl radicals.

What does this discovery mean for our health? What do we know, and what are scientists still investigating?

In this episode, we'll explore:

• New 2026 research: How microplastics interact with water and why scientists are interested.

• Swallowing vs. absorbing: Why eating a plastic particle doesn't necessarily mean it enters your bloodstream.

• Plastic numbers 1–7: What those little numbers really mean, and why they aren't safety ratings.

• Microwave safety: Why transferring food into glass or ceramic containers can be a useful habit.

• New scientific solutions: How researchers at UC Berkeley and USC are developing ways to recycle plastics and create alternatives.

🌱 JOIN OUR 7-DAY TAKEOUT CHALLENGE!

Choose one disposable item you regularly use, such as a plastic cup, lid, straw, or utensils.

For seven days, try one practical alternative. You could skip unnecessary utensils, bring a reusable water bottle, or transfer takeout food into a microwave-safe glass bowl before reheating.

Notice what works, what gets in the way, and what you might want to keep doing.

Small actions can add up when we share them with friends!

Can AI help you finish homework faster but make it harder to think on your own?

In a 2025 study, students using a basic AI assistant performed better during math practice. But when AI was removed, they scored 17% lower on independent exams compared with students who practiced without AI.

So, is AI making us smarter or just making us more dependent?

I'm Titus Ko, your host at Teens Inspiring Teens: Healthy Teens, Healthy Planet, a student-led 501(c)(3) nonprofit.

In this episode, we explore three scientific studies from the University of Pennsylvania, Harvard University, and Microsoft Research with Carnegie Mellon University.

We'll discover:

• Why getting the correct answer doesn't always mean you've learned something.
• How an AI tutor designed to give hints can improve learning.
• Why confidence in AI isn't the same as critical thinking.
• How to use AI for homework without giving up independent thinking.

🧠 THE 7-DAY AI BRAIN CHALLENGE

Try this for just 10–15 minutes a day!

Day 1: Solve three questions without AI. Record your starting score.

Day 2: Try solving problems first. Ask AI for hints instead of answers.

Day 3: Ask AI to teach you something, then explain it back without looking.

Day 4: Fact-check an AI answer using your textbook or trusted sources.

Day 5: Solve a new version of a problem without copying the AI's method.

Day 6: Take a mini quiz with no AI help.

Day 7: Solve three fresh questions independently and compare your results with Day 1.

The challenge isn't about avoiding AI. It's about learning how to use it wisely. Your score is a personal practice check, not a scientific te

Ever looked up before bed and wondered where all your time went? You're not alone. In this video, we break down a recent 2026 study from JAMA Pediatrics on teen phone use at night, look at sleep guidelines from the American Academy of Sleep Medicine, and launch a simple 7-Day Challenge to help you put your phone away when you actually want to!

🧠 What you'll learn in this video:

- How much time teens actually spend on phones between 10 PM and 6 AM

- The impact of night scrolling on your sleep and health

- A simple, 3-step 7-day challenge to build better nighttime habits
