Backpacks are packed, lunchboxes are labeled, and the bell is ringing in a new school year. But alongside the thrill of fresh notebooks and fall routines comes something less exciting: increased risk of sniffles, sneezes, and seasonal sickness. As kids return to classrooms, germs tag along—and families may wonder what they can do to stay one step ahead.

Thankfully, there’s a lot you can do! By embracing healthy habits and making a few intentional lifestyle shifts, you can help strengthen your child’s (and your own!) immune system and give your household a better shot at a smooth, healthy school year.

At Healthier 901, we believe health isn’t just something you react to: it’s something you can build. That’s why we’re committed to empowering you with practical, evidence-based tools to feel your best in every season—especially as peak respiratory season approaches.

Why immune health matters now

Once school starts, children are exposed to more people, more surfaces, and by extension, more germs. While minor illnesses are often part of building a resilient immune system, consistent support through lifestyle choices can help reduce how often—and how severely—those illnesses strike. According to pediatric experts, core pillars like nutritious eating, physical activity, sleep, and stress management are essential to bolstering the body’s natural defenses.

“There’s no magic vitamin or supplement that can replace the basics. A well-balanced diet, regular movement, restorative sleep, and healthy stress management are the best ways to support your child’s immune system and overall well-being.” – Landon Pendergrass, MD, with Le Bonheur Pediatrics

Immunity-boosting tips for back-to-school

Ready to give your family a healthy head start? Here are eight science-backed strategies to help keep immune systems strong throughout the school year:

1. Prioritize sleep, every night. Kids need 9–11 hours of sleep each night to allow their bodies time to repair and recharge. Stick to a consistent bedtime routine and wind down with screen-free time before bed.

2. Fuel up with nutritious meals and snacks. Serve balanced meals rich in fruits, vegetables, lean proteins, whole grains, and healthy fats. A hearty, high-protein breakfast helps kids stay focused and energized all morning.

3. Encourage daily movement. Physical activity supports circulation and helps immune cells do their job. Aim for at least 60 minutes of moderate activity each day—even if it’s just a walk or dance break after dinner.

4. Manage stress in healthy ways. School-related anxiety is real, and chronic stress can weaken the immune system. Encourage your child to talk about their feelings and try techniques like deep breathing or stretching together.

5. Stay hydrated. Water helps transport nutrients, regulate body temperature, and flush out toxins. Send kids to school with a refillable water bottle—and model good hydration habits yourself.

6. Promote excellent hygiene. Handwashing is still one of the most effective tools for preventing illness. Teach kids to wash with soap and water for at least 20 seconds and to sneeze or cough into their elbow.

7. Limit screen time, especially before bed. Excess screen time can disrupt sleep and raise stress levels. Keep recreational screen use under two hours per day and power down devices at least 30 minutes before bedtime.

8. Don’t skip those check-ups. Annual wellness visits and up-to-date vaccinations are important for preventing illness and catching any potential health concerns early.

“It’s easy to overlook the small, daily habits that play a big role in health. But the truth is, small steps—like packing a balanced lunch or carving out 10 minutes to walk and talk with your child about their day—can make a big difference in both immunity and emotional well-being.” – Landon Pendergrass, MD, with Le Bonheur Pediatrics

Keep up the good work all year long

Back-to-school doesn’t have to mean back-to-sick days. By making smart, consistent choices, you can help set your child up for a school year filled with energy, learning, and fewer sniffles.
