How to keep immune system healthy

To maintain a healthy immune system, Andrew Huberman suggests several strategies. Here are some key points:

1. Avoid Touching Eyes: The eyes are a major entry point for viruses and bacteria. It's essential to avoid touching them after being in contact with potentially contaminated surfaces. Keeping your hands clean is crucial 1.

2. Promote Gut Health: Enhance your gut microbiome with 2-4 servings of low-sugar fermented foods daily, such as kimchi or sauerkraut, to bolster the immune system and reduce inflammation 1.

3. Regular Sauna Use: Sauna sessions can boost the innate immune system by increasing leukocyte production. If you aren't used to high heat, start with moderate sessions to stimulate your immune response effectively 2.

4. Balanced Exercise: Incorporate high-intensity workouts as short as 12 minutes into your routine. These should be intense but balanced with longer cardio and strength training to keep the immune system robust 3.

5. Maintain Humidity: Use a humidifier to keep nasal passages moist, supporting your respiratory system's defenses during flu season, especially when indoors for extended periods 4.

6. Stress Management: Manage stress, as chronic stress can impair immunity. However, brief stress episodes may enhance immunity if they don't disrupt sleep 5.

By following these guidelines, you can help your immune system stay strong and effectively combat illnesses.
