Supporting the Immune System as the Seasons Change
Non-member article, published Sept 17, 2025.
Adjusting to Seasonal Shifts
As the seasons shift and the air grows cooler, our bodies naturally adjust to the changing environment. The soil, plants, and air go through seasonal transformations, which can subtly affect our bodies and immune system. These shifts can influence how the body responds to the variety of viruses and microbes we encounter - reminders that our immune system is constantly learning and adapting.
Viruses Are Part of the Body
Colds and flu aren’t something to fear - they can be signals that the body is out of balance or that the immune system is being “reminded” to stay sharp. In fact, as Dr. Zach Bush shares, the human body naturally hosts enormous numbers of viruses at any given time - around 100 million (10⁸) viruses - illustrating that viruses are a normal part of our biology. Rather than something to avoid, they are part of the ongoing process of keeping the immune system active and resilient.
Preparing the Body Thoughtfully
Supporting the body through seasonal transitions doesn’t mean avoiding viruses altogether; it’s about preparing the body in ways that align with individual health needs and the guidance of medical professionals. Simple adjustments, like ensuring nutrient-rich foods and targeted supplementation, can help create an environment where the immune system functions optimally.

Preparing for Fall
As the seasons shift and the air grows cooler, supporting the immune system is about more than just supplementation. Supplements, such as those in Fullscript’s expert-designed immune support plan, are meant to complement a nutrient-rich diet - they can’t replace healthy food choices, and they aren’t appropriate for everyone. It’s important to work with a medical practitioner or licensed nutritionist to determine what aligns with individual needs. Preparing for seasonal changes also includes prioritizing sleep, staying hydrated, moving your body, managing stress, nourishment with whole nutrient rich foods, spending time with friends and in communities that fuel and nourish you, and nurturing your overall well-being. When approached thoughtfully, these strategies help create an environment where the immune system can function optimally and your body can thrive.
