Patients with facial palsy should preferably not drink beer during treatment, and they should also not smoke as well as consume spicy foods, such as seafood products. This is because these things can stimulate the facial nerve and aggravate the symptoms of facial palsy. During the treatment period, facial palsy patients should also pay attention to keeping their face warm to prevent it from getting cold. Facial palsy is mostly caused by the invasion of cold air from outside, which leads to facial nerve dysfunction and inability to innervate facial muscles, resulting in muscle stiffness and restricted movement. Therefore, facial palsy patients should pay attention to the factors that aggravate facial palsy and wear a mask before going out to prevent getting cold. Recovery from facial palsy usually takes 3-6 months, so it is best not to drink alcohol during this period.
