It is caused by the reactivation of the varicella-zoster virus—the same virus that causes chickenpox.
What Herpes Zoster (Shingles) REALLY Is
After you recover from chickenpox, the virus stays dormant (inactive) in your nerve cells for years—sometimes decades.
It can reactivate when the immune system is weakened.
What Actually Triggers Shingles
✔ Weakened immunity (aging, illness)
✔ Severe or chronic stress
✔ Lack of sleep / exhaustion
✔ Cancer, HIV, autoimmune disease
✔ Chemotherapy or steroid use
✔ Recent surgery or trauma
🚫 NOT caused by:
-
Cold weather
-
Mucus buildup
-
Cold showers
-
Cold drinks
-
Poor hygiene
Those are common myths.
