Respiratory Viruses: Building Immunity That Protects You

By FXMed Team

Why Some People Get Every Virus Going

In Lagos's crowded offices, markets, and transport, respiratory viruses circulate continuously. Yet some people seem to catch every illness while others rarely get sick. The difference is almost never luck — it reflects the underlying state of your immune system, nutritional status, and stress resilience.

What Makes You More Vulnerable

FXMed tip: If any of this sounds familiar, our Immune Support Programme may be exactly what you need. Book a free assessment to find out where your health stands today.

  • Vitamin D deficiency — vitamin D is the immune system's master switch; deficiency more than doubles infection risk
  • Zinc deficiency — zinc is required for the production of T-lymphocytes and natural killer cells that fight viral infection
  • Chronic stress — cortisol suppresses immune function; Lagos's high-pressure environment is a genuine immune suppressor
  • Poor sleep (see our sleep health guide) — immune regeneration happens during deep sleep; consistently less than 7 hours cuts immune effectiveness by 30%
  • Gut dysbiosis — 70% of immune tissue lines the gut; microbiome (see our gut health guide for Lagos professionals) imbalance directly impairs systemic immune response
  • Processed food diet — ultra-processed foods drive systemic inflammation that diverts immune resources

Evidence-Based Immune Support

  • Vitamin D3 optimisation (target serum level 60–80 ng/mL)
  • Zinc supplementation at maintenance doses
  • Elderberry and quercetin — both with clinical evidence for respiratory virus protection
  • Probiotic strains targeted to respiratory immunity (Lactobacillus rhamnosus GG, L. acidophilus)
  • Sleep hygiene that protects immune regeneration
