What is the reason for facial paralysis caused by air conditioning

The hot summer is coming, and many people turn on the air conditioner when they return home from outdoors. In fact, this practice is not advisable because it will stimulate the nerves in the pores of the face, resulting in symptoms of facial paralysis. You can learn more about this.

The weather is hot in summer, sweating increases, and the pores all over the body are open. When the nerves and blood vessels around the face are stimulated by cold, it is easy to cause spasms, blood circulation disorders, and lead to facial paralysis. Using the air conditioner for a long time, setting the temperature too low, or entering and leaving an environment with a large temperature difference, as well as sweating profusely after exercise and being blown directly into the air conditioner or electric fan are all common causes of acute facial paralysis.

Facial paralysis occurs suddenly, often without precursor symptoms. The typical symptoms are inability to frown the forehead on the affected side, disappearance of forehead wrinkles, drooping eyebrows, inability to close eyes, enlarged palpebral fissure, disappearance of nasolabial groove, philtral ridge deviating to the opposite side, food easily accumulated in the gingival-buccal groove, buccal mucosa often bitten involuntarily, drooping corners of the mouth, lower lip tilting to the opposite side when opening the mouth, water flowing out of the corners of the mouth when drinking or rinsing the mouth, inability to blow air or puff up the cheeks, unclear pronunciation when making labiodental sounds, and most patients have varying degrees of pain and tenderness behind the earlobe on the paralyzed side.

If you suffer from facial paralysis, you should go to the hospital for treatment in time to rule out other diseases causing facial paralysis. Worry and tension will aggravate facial nerve and vascular spasm and ischemic damage, so pay attention to keeping the affected side warm, especially be careful not to let the affected side of the head and face be exposed to wind and cold, and take some B vitamins, compound danshen tablets, dichlorobenzene, cytidine and other blood-activating and neuroactive drugs in appropriate amounts.

Physical therapy can include acupuncture, far infrared, laser irradiation, ultrashort wave thermal diathermy, hot compresses around the affected mastoid area, and massage, etc., which can promote the early dissipation of facial nerve edema and the recovery of nerve function. However, special attention should be paid to the prohibition of rapid direct current stimulation during the acute period of two weeks after onset, so as not to aggravate the degeneration and damage of the facial nerve.

At the same time, functional exercises should be carried out as early as possible. Patients can do actions such as raising eyebrows, raising forehead, closing eyes, whistling, and puffing cheeks in front of a mirror. As long as facial paralysis caused by cold wind is treated promptly and correctly and attention is paid to rest, most patients can be completely cured within 3 to 6 months.
