Why Some People Get Sick More Often Than Others

Genetics determine part of your immune response speed.
Poor sleep, nutrition, or chronic stress weaken resistance.
Smoking and pollution impair protective barriers.
Frequent contact with crowds increases exposure chances.
Certain medications suppress immune function.
Gut health differences also play a major role.
Over-sanitization can reduce immune “training.”
Children and elderly have naturally weaker defenses.
Consistent lifestyle habits build durable resilience.
Immunity is personal—no two systems fight alike.
