From Strangers to a Team : This Is How It Begins!

There's something magical about the moment a group of strangers becomes a team.

On September 12, 2026, COOL Lab welcomed its newest volunteers at the Canadian University of Bangladesh for our Summer 2026 Orientation and what a morning it was!

From the moment volunteers walked in, they were greeted by name by Research Assistants Akbor Hosain Santo and Mehedia Muna a small gesture that set the tone for everything that followed. Nobody walked in as an outsider.

The program was anchored with warmth and structure by Lab Coordinator Md. SM Sajid and Research Assistant Israt Jahan Mohona. Then Lab Head Mohammad Hamid Al Muktadir took the floor to share the story of how COOL Lab came to be and why it exists.

"Our mission is grounded in evidence-based inquiry and the belief that science can meaningfully improve health trajectories starting from early childhood," he told the new recruits. It was a mission statement, but it landed like an invitation.

🎯 More highlights from the day:
✅ A fun COOL Lab-themed bingo game that turned strangers into collaborators—congrats to Elma Zahan Esha for winning first prize!
✅ A powerful role-play on real-world data collection titled "Gobeshonar Bishoy," written by Refat Jahan Busra and performed by Mushfiq Alam and Md. S M Sajid
✅ Volunteers submitting their own research ideas from day one—because their voices matter
✅ Honest, personal stories from Research Assistants Mehedia Muna, Tahsin Tabassum, Mushfiq Alam, and Hossain Sakib Chayan about growing within COOL Lab
✅ A heartfelt closing note from Co-Supervisor Maria Haider Shanta, reminding everyone they're part of something larger than a single project

By the time the hall emptied, nervous smiles had transformed into confident ones. Our new volunteers arrived as strangers and left as a team ready to turn evidence into action, one child, one family, one community at a time.

"Ever wonder what actually goes into keeping a community healthy? It takes more than just doctors and hospitals."

At COOL Lab, we believe that strong public health isn't just about reacting to illness—it's about building systems that prevent it in the first place.

That’s why we’re sharing this powerful framework: The 8 Capabilities Every Public Health System Needs.

From Surveillance that catches early warning signs, to Promotion that empowers you to live healthier, to Communication that ensures transparent information—every single piece of this puzzle is vital.

When these 8 capabilities work together in harmony, we don't just manage crises; we prevent them. We save lives. And we build healthier, resilient communities for our children and families.

💬 We want to hear from you!
Which of these 8 capabilities do you think is most crucial right now in your local community? Let us know in the comments! 👇

Visit lab-cool.org to see how our research supports these pillars.

The biggest warning sign often isn't more screen time.

It's what starts disappearing because of it.

Sleep. Outdoor play. Conversation. Curiosity.

Our latest article explores why these subtle changes deserve more attention—and what parents can do before they become lasting habits.

📸 Swiping through the Fall 2025 archives and feeling so proud of this team!

From measuring heights on the street to chatting with local shop owners about food access, our COOL Lab volunteers were OUT THERE doing the work. This isn't just research; it's real connections, real data, and real steps toward healthier communities.

Our volunteers were out measuring heights in alleyways, interviewing shopkeepers about what they stock and why, and collecting data in neighborhoods where most researchers don't bother showing up. No simulations. No textbooks. Just fieldwork on childhood obesity in Dhaka, with communities who let us in.

BUT HERE IS THE EXCITING PART: We are already gearing up for our Summer 2026 projects, and we are looking for new faces to join the squad! 🧬📋

Are you a student or an aspiring researcher who wants to trade the classroom for the real world? At COOL Lab, you don't just sit in a lab you get your hands dirty (in the best way!) learning how to fight childhood obesity from the ground up.

👉 Why join us?
✅ Get real training in data collection and analysis
✅ Learn directly from senior researchers
✅ Earn a verified certificate (and maybe even your name on a publication!)
✅ Be part of a team that actually cares about the communities we serve

If you're a public health student or fresh graduate in Bangladesh who wants real research experience on your CV, not just coursework, this is it. You'll learn data collection, analysis, and academic writing by doing them, with researchers who can actually vouch for your work when you're done.

It is an unpaid position, but we promise the experience and mentorship are priceless.

⚠️ Deadline is approaching fast: 14 August 2026! (Only BDT 150 to register).

✨ Drop a ❤️ in the comments if you’d tag a friend who needs to see this! Let’s build the next generation of public health leaders together.

Research days don't always look like fieldwork ,sometimes they look like this.

Today our Lab Head, Mohammad Hamid Al Muktadir, pulled the team together to go through all the physical activity and sleep data we collected during the Fall 2025 semester. Before we can analyze anything, we need to make sure every entry is accurate and consistent. That means going record by record, catching errors, and agreeing on how to handle anything unusual.

A rough comparison: before you bake, you check whether your measurements are right. We're doing the same thing, except the recipe is children's health research and getting it wrong has real consequences.

Our researchers spent hours on this today. What comes out of that work will eventually become findings we can share with families, clinicians, and policymakers. That's the part worth waiting for.

One day. 24 hours. A whole lot of potential for our kids! 💪

Have you ever thought about what a "healthy day" really looks like for a child? 🤔 It’s more than just eating your veggies—it's a perfect recipe of movement, rest, and play!

At COOL Lab, we love this simple but powerful 24-Hour Movement Guideline for children and youth (5–17 years). It breaks down the perfect day into easy-to-understand parts:

🌙 Sleep: 9-11 hours of quality shut-eye to recharge those growing brains!
🏃‍♀️ Physical Activity: At least 60 minutes of heart-pumping, fun movement.
🛋️ Light Activity & Breaks: Don't sit for too long! Light movement throughout the day keeps energy flowing.
📱 Recreational Screen Time: A limit of 2 hours to balance fun with movement.

The goal? Move more, sit less, sleep well! ✨ It’s not about being perfect, but about making small, healthy choices every hour of the day.

Question for our families:
What is your child's favorite way to get their 60 minutes of activity in? Share your tips for getting active as a family below! 👇
