Cranial nerve 7 is a motor nerve that controls facial muscle movement. Peripheral facial nerve palsy is a condition of complete loss of movement or weakness of the muscles of half the face, which occurs when this nerve is compressed and causes inflammation.

75% of cases occur when the body is suddenly cold. When the body is weak, combined with the habit of leaving the air conditioner or fan blowing directly on the face, bathing at night, getting wet in the rain, going from an air-conditioned room to hot weather or from outside to an air-conditioned room suddenly, this condition can occur. Children with Bell's palsy are mainly caused by cold.

To prevent illness, everyone should keep the child's head, face, and neck warm. When it's cold, avoid opening the door suddenly to let the cold wind blow into the child's face. At night, don't let the child sit near the window to avoid drafts.

You should bathe your child at one of two times: 9:30-10:30am or 1-4pm. Bathing time should only be about 5-10 minutes for older children and no more than 2-3 minutes for younger children.

Limit children from going out at night. If they go out, they need to wear warm clothes, wrap a scarf, wear a hat, and play for a short time. Children traveling long distances must cover their jaws and wear masks. Children should not sit in the front of the car. They should protect their heads and necks. They should wear enough warm clothes and avoid sudden changes in temperature, such as from hot to cold.
