Dormant Viruses & Viral Reactivation

What Are Dormant Viruses?

Dormant viruses, also known as latent viruses, can stay hidden in your body for years without causing symptoms. Common examples include herpes viruses (like Epstein-Barr and shingles), cytomegalovirus, and even certain cold viruses. They become active again when your immune system is compromised due to stress, illness, or poor lifestyle choices.

Signs of Viral Reactivation

Many people experience viral reactivation without realising it. Symptoms can include:

• Fatigue and brain fog

• Muscle aches and joint pain

• Skin rashes or cold sores

• Gut issues and food intolerances

• Weakened immune function

Why Do Viruses Reactivate?

Several factors can trigger dormant viruses, including:

• Chronic stress and poor sleep

• Nutrient deficiencies (e.g. vitamin D, zinc)

• Gut dysbiosis and leaky gut

• Environmental toxins

• Other infections (e.g. Lyme disease, mould exposure)

How Functional Medicine Can Help

Instead of just treating symptoms, functional medicine looks at root causes and supports your body's natural defences. Strategies include:

• Optimising gut health – A balanced microbiome strengthens immunity.

• Reducing stress – Mindfulness, breathwork, and adaptogenic herbs help regulate the nervous system.

• Targeted nutrition – Key nutrients like vitamin C, quercetin, and omega-3s support immune resilience.

• Detoxification – Minimising toxins from food, water, and the environment reduces viral burden.

• Antiviral herbs – Lemon balm, astragalus, and reishi mushroom have natural immune-boosting properties.
