COLD WEATHER AND SEASONAL CHANGES: BE ALERT FOR PERIPHERAL FACIAL NERVE PALSY (7TH CRANIAL NERVE PALSY)

When the weather turns cold or during seasonal transitions, the body often becomes more sensitive. According to Dr. Hoang Van Duc, Specialist Level I (Head of Traditional Medicine Department – Thai Nguyen International Hospital):

“This is also the time when cases of peripheral facial nerve palsy (commonly known as facial paralysis) tend to increase.”

WHAT IS PERIPHERAL 7TH CRANIAL NERVE PALSY?

Peripheral facial nerve palsy is a common clinical condition characterized by weakness or paralysis of the facial muscles on one side, which significantly affects facial appearance, chewing function, speech, and the patient’s psychological well-being.

Among the causes, facial nerve palsy triggered by cold exposure accounts for a considerable proportion. The condition often develops suddenly after exposure to cold wind, cold weather, or abrupt temperature changes.

WARNING SIGNS YOU SHOULD NOT IGNORE

People should pay special attention and seek medical care promptly if experiencing the following symptoms:

• Mouth drooping or facial asymmetry when smiling or speaking
• Inability to fully close the eye, watery eyes, or dry eyes
• Loss or reduction of forehead wrinkles on one side
• Numbness or tingling sensation on the affected side of the face
• Reduced sense of taste
• Difficulty blowing air, whistling, or food and drink spilling easily

POSSIBLE CAUSES

Dr. Hoang Van Duc explains that cold weather, drafts, or sudden temperature changes may cause vasoconstriction and swelling of the facial nerve, leading to facial paralysis. In addition, factors such as weakened immunity, viral infections, and ear–nose–throat inflammation may also increase the risk of developing peripheral facial nerve palsy.

EARLY TREATMENT BRINGS BETTER RECOVERY

Peripheral 7th cranial nerve palsy has a high chance of full recovery if detected early and treated promptly.

At Thai Nguyen International Hospital, patients receive comprehensive examination and assessment, followed by an appropriate treatment plan that may include:

• Traditional medicine therapies tailored to each individual case
• Physical therapy and rehabilitation, including facial muscle exercises
• Medical treatment when indicated by specialist doctors

Among these methods, acupuncture is considered the key treatment approach and plays a crucial role in managing peripheral facial nerve palsy. It is widely chosen by both specialists and patients thanks to its high effectiveness (over 90% of patients can recover completely) and safety.

RECOMMENDATIONS FOR PREVENTION DURING COLD SEASON

To protect your health and that of your loved ones during harsh winter weather, Dr. Hoang Van Duc recommends the following simple habits:

• Keep your body warm, especially the head, face, and neck when going outside
• Avoid cold drafts: do not let fans or air conditioners blow directly onto your face, especially while sleeping
• Avoid showering too late at night and do not take sudden cold showers
• If facial asymmetry occurs, visit a medical facility as soon as possible, ideally within the first 7 days, to achieve the best recovery outcome
