Hot compress when sleeping. You can also complain with a hot towel, soak a cup of hot Jiang Shui, and then put it under your nose for a while, and your nose will be ventilated. I've tried it before, and this method is very effective. But the disadvantage is that after the nose is removed, it will soon be blocked again. It is suggested that the landlord should cure the cold quickly to avoid rhinitis, which would be in trouble. I hope the following methods can help you. 1. Massage the nasal groove: rub your hands together, and massage Xiang Ying point (located in the nasal groove and at the midpoint of the outer edge of the flat nose) for more than ten times after the palm gets hot, which can prevent colds and relieve the symptoms of nasal congestion after colds. 2, nose onion: What should I do if my nose is not ventilated after a cold? When sleeping, you can put a fresh onion strip in each nostril and take it out after 3 hours, usually once. If not, you can plug it in the next day. It is worth reminding: first of all, the onion strips should be thicker and thinner. First, the drug intensity is small; Second, it is easy to inhale deep into the nasal cavity and not easy to take out; Secondly, if the patient's nasal cavity is allergic to fresh onions, a thin layer of cotton can be wrapped around the onion strips. 3, breathing steam: when the first cold, pour boiling water into the cup, take a deep breath into the hot air, until the water in the cup becomes cold, several times a day, can reduce the symptoms of nasal congestion. 4, drug treatment: the fastest effect, but not very serious, try not to use drugs. You must consult your doctor about specific drugs.
