Naturally strengthen the immune system: The 10 best strategies for autumn

Autumn not only brings colorful leaves and cozy evenings, but unfortunately also the first cold wave of the year. When temperatures drop and we spend more time indoors, our immune system is particularly challenged. But with the right natural strategies, you can strengthen your defenses and get through the cooler season healthily.

Why is the immune system particularly challenged in autumn?

The cooler months present special challenges for our bodies. Less sunlight leads to a vitamin D deficiency,dry heating air irritates our mucous membranes, and being in closer proximity to others indoors increases the risk of infection. At the same time, the transition from warm to cold temperatures can stress our body and weaken the immune defense.

The 10 best natural strategies for a strong immune system

1. Supplement vitamin D specifically

Why it is important: Vitamin D plays a central role in immune regulation and helps fend off infections. In autumn and winter, our body produces less sun exposure significantly less vitamin D.

How to implement it:

• Have your vitamin D levels checked by a doctor
• If deficient, supplement with 800 IU daily (What)
• Take advantage of sunny autumn days for outdoor walks
• Eat vitamin D-rich foods like fatty fish, eggs, and Mushrooms

2. Promote gut health through probiotics

Why it matters: About 70% of our immune system is located in the gut. A healthy gut flora is therefore essential for strong immune defenses.

Here's how to do it:

• Incorporate fermented foods like sauerkraut, kimchi or kefir into your diet
• Eat prebiotic foods like onions, garlic, and artichokes
• Reduce Sugar and processed foods
• Consider a high-quality probiotic if needed

3. Get enough restful sleep

Why it's important: During sleep, our immune system regenerates and forms important defense cells. Lack of sleep has been shown to weaken immune defense.

Here's how to implement it:

• Sleep 7-9 hours per night
• Maintain consistent sleep schedule
• Create a cool, dark sleeping environment
• Avoid screens 1-2 hours before bedtime
• Develop a relaxing bedtime routine

4. Actively reduce stress

Why it's important: Chronic stress increases the stress hormone cortisol, which suppresses the immune system and makes us more susceptible to infections.

This is how to implement it:

• Practice 10-15 minutes daily meditation or mindfulness exercises
• Consciously plan relaxation times into your day
• Try breathing techniques like the 4-7-8 method
• Reduce sources of stress where possible
• Seek professional help for chronic stress

5. Exercise regularly but moderately

Why it's important: Moderate physical activity boosts the immune system, while excessive exercise can temporarily weaken it.

How to implement it:

• Engage in 30 minutes of moderate exercise daily (brisk walking, cycling)
• Use the stairs instead of the elevator
• Even go for walks in bad weather in the fresh air
• Try out Yoga or Tai Chi for exercise and relaxation
• Avoid overly intense workouts

6. Use immune-boosting foods strategically

Why it is important: Certain foods contain natural compounds that directly support the immune system and reduce inflammation.

How to implement it:

• Ginger: Drink ginger tea daily or use fresh ginger in cooking
• Garlic: Integrate 1-2 cloves of garlic into your meals daily
• Citrus fruits: Eat Vitamin-C rich fruits daily, such as oranges, lemons, or grapefruits
• Berries: Enjoy antioxidant-rich berries like blueberries or cranberries
• Leafy greens: Eat spinach, kale, or broccoli daily

7. Drink plenty of fluids and keep mucous membranes moist

Why it is important: Well-hydrated mucous membranes can better ward off viruses and bacteria. Dry heating air in autumn makes adequate fluid intake particularly important.

Here's how to implement it:

• Drink 1.5-2 liters of water or unsweetened teas daily
• Use a humidifier in heated rooms
• Inhale with salt water for dry mucous membranes
• Drink warm herbal teas like chamomile, sage, or thyme
• Reduce dehydrating drinks like Alcohol and Caffeine

8. Cold-Warm Stimuli for Immune Training

Why it is important: Temperature stimuli train the immune system and improve circulation. This strengthens the natural defenses.

How to implement it:

• Start with short cold showers (30 seconds)
• Alternate between warm and cold water temperatures
• Try sauna sessions followed by cooling down
• Go for regular walks in cool weather
• Gradually increase the cold stimuli and listen to your body

9. Maintain social contacts and observe hygiene

Why it is important: Social isolation weakens the immune system, while too close contact without hygiene measures increases the risk of infection.

How to implement:

• Maintain regular social contacts, even outdoors
• Wash your hands frequently and thoroughly
• Avoid touching your face, nose, and mouth
• Keep your distance from others if you have cold symptoms
• Ventilate closed rooms regularly

10. Use natural medicinal plants and home remedies

Why it is important: Many medicinal plants are said to have immune-strengthening and antiviral properties. However, please note that for many, the study situation regarding effectiveness is limited or their health effects in humans have not been sufficiently investigated or scientifically proven.

How to implement it:

• Echinacea: Take Echinacea supplements at the first sign of a cold
• Elderberries: Drink elderberry juice or syrup preventively
• Propolis: Use propolis drops or spray for the throat
• Cistus tea: Drink 2-3 cups of antiviral cistus tea daily
• Manuka honey: Take a teaspoon of high-quality Manuka honey daily
