Autumn immunity: How to strengthen your health during seasonal changes?

As temperatures drop and daylight hours shorten, our bodies face new stressors. The transition from summer to autumn often brings:

Increased exposure to viruses (especially in schools and workplaces);
Fluctuating temperatures that strain thermoregulation;
Lower vitamin D levels due to reduced sunlight;
Changes in sleep patterns and mood.

These factors can weaken immune defenses, especially in adolescents and young adults whose bodies are still adapting to hormonal shifts.

Puberty and immunity: A critical connection

Puberty is a transformative period not only for physical development but also for the immune system. According to recent research, hormonal changes during puberty - particularly the rise in sex hormones - significantly influence immune function:

Increased cytokine production and antibody responses;
Enhanced activity of dendritic cells and T-helper cells;
Greater susceptibility to autoimmune conditions like multiple sclerosis post-puberty.

This means that teens and young adults may experience temporary immune imbalances, making them more vulnerable to infections during seasonal transitions.

Sleep: The foundation of immune resilience

Sleep is one of the most powerful tools for immune health - especially during adolescence.

Teens need 8–10 hours of sleep per night, yet over 70% of high school students report getting less than 7 hours. Chronic sleep deprivation increases inflammation and lowers resistance to viruses. Poor sleep disrupts melatonin production, which plays a role in immune regulation

Tips for better sleep

Maintain a consistent bedtime, even on weekends;
Limit screen time 1 hour before bed;
Create a calming nighttime routine (reading, journaling, herbal tea).

Nutrition: Fueling the immune system

A balanced diet rich in antioxidants, vitamins, and minerals is essential for immune strength.

Key nutrients for autumn immunity:

Vitamin C (citrus fruits, bell peppers, broccoli);
Vitamin D (fatty fish, fortified foods, supplements);
Zinc (pumpkin seeds, legumes, whole grains);
Probiotics (yogurt, kefir, fermented vegetables).

Practical advice:

Add seasonal produce like apples, beets, and squash to meals;
Stay hydrated - dry indoor air can dehydrate mucous membranes;
Limit processed sugar, which suppresses white blood cell activity.

Movement: Exercise as immune medicine

Regular physical activity boosts circulation, reduces stress, and enhances immune surveillance.

Moderate exercise (30–60 minutes/day) improves immune markers.
Overtraining, especially in adolescents, can temporarily suppress immunity.
Outdoor movement increases vitamin D and mood - even a brisk walk counts!

Autumn-friendly activities:

Nature walks in parks or forests;
Dance workouts at home;
Team sports with proper warm-up and recovery.

Emotional wellness

Stress and emotional strain can weaken immunity. Adolescents are especially vulnerable due to academic pressure, social dynamics, and hormonal fluctuations.

Supportive strategies:

Practice mindfulness or breathing exercises;
Encourage open conversations about feelings;
Limit multitasking and overstimulation.

Immune checklist for Autumn

Here’s a simple guide to help teens and adults stay resilient this season:

Get 8+ hours of sleep;
Eat colorful, nutrient-rich meals;
Move your body daily ;
Supplement vitamin D if needed ;
Practice stress-reducing habits;
Schedule preventive checkups (especially for teens).
