Can Cold Air Cause Facial Palsy? The Truth About Drafts, Air Conditioning and 7 Common Bell’s Palsy Myths

“You must have caught a cold draft!” In much of the Arab world this is the first thing anyone with facial palsy hears. But can cold air cause facial palsy? Here’s what the science says — and the most common myths that can delay proper treatment.

What does the science say about cold air?

Research suggests Bell’s palsy is caused by inflammation and swelling of the facial nerve, most likely from a reactivated virus such as herpes simplex. We explain this in what causes Bell’s palsy.

As for cold air:

• There is no conclusive evidence that it directly causes palsy.
• Some studies have noted slightly more cases in colder months, but this may be explained by more colds and flu in winter rather than the air itself.
• Palsy often appears in the morning after waking, because symptoms develop over hours — so people blame night air or the air conditioner.

Bottom line: cold air is probably not the direct cause. And even if it plays an indirect role, the treatment is the same: early diagnosis, steroids where appropriate, eye protection and rehabilitation.

7 common myths about Bell’s palsy

Myth 1: “It’s just a draft — no need for a doctor”

Fact: sudden facial palsy needs medical assessment within 72 hours. Early treatment improves recovery, and a doctor rules out dangerous causes such as stroke.

Myth 2: “Cauterisation or cupping cures it”

Fact: there’s no scientific evidence for either, and both can cause burns, scarring and infection. See our treatment guide for what is actually supported by evidence.

Myth 3: “Don’t wash your face or shower”

Fact: hygiene is safe and important. Just protect the affected eye from water and soap and pat it dry gently.

Myth 4: “Chew lots of gum to strengthen your face”

Fact: excessive chewing overworks the healthy side and increases asymmetry. Good exercises are slow, precise and symmetrical — see common exercise mistakes.

Myth 5: “The harder you exercise, the faster you recover”

Fact: forceful movements may increase the risk of synkinesis. Quality matters more than strength.

Myth 6: “Facial palsy is permanent”

Fact: most people with Bell’s palsy recover fully or almost fully, and improvement usually starts within weeks. See Bell’s palsy recovery time.

Myth 7: “Facial palsy is contagious”

Fact: Bell’s palsy is not contagious and cannot be passed on to others.

So should I shield my face from wind?

Yes — but for a different reason: the affected eye doesn’t blink properly, so direct airflow dries it out fast. So:

• Don’t point the air conditioner or fan directly at your face.
• Wear glasses outdoors, especially in wind and dust.
• Use artificial tears regularly — see our eye care guide.
