After suffering from respiratory infectious diseases, people often feel stuffy nose. Try these moves, which may be more comfortable and can be used by the whole family: 1. Increase humidity: the nasal mucosa of the "small environment" that the nose likes to be wet, and dryness will aggravate the stuffy nose. You can use a beaker of warm water, place your nose close to the cup mouth (not too close to avoid burns), and inhale steam for 5-10 minutes; Alternatively, after taking a shower, you can stay in the bathroom for a while longer and use the water vapor in the bathroom to moisturize your nose. This will make your nose soft and relieve nasal congestion. Putting a humidifier at home and adjusting the humidity to 50% to 60% is also very effective. 2、 Moisturizing nasal mucosa: Spray physiological saline on the nose. You can use physiological saline nasal spray or nasal wash salt, spray 2-3 times a day, 1-2 times per nostril each time. It does not contain drugs, is mild and safe, and can be used by infants and pregnant women. It can directly wet the nasal mucosa, dilute nasal mucus, and flush out bacteria in the nasal cavity, effectively relieving nasal congestion. 3、 Assistive ventilation: Use as needed to make nasal congestion more comfortable and affect sleep. You can adjust your sleeping posture, try sleeping on your side, raise your head a bit, and use gravity to reduce nasal congestion. Older children and adults can use ventilation nasal patches to physically dilate their nasal cavity. This will not affect health, but should not be used for more than 12 hours per day. If there is local skin rupture or allergy, it should be avoided. Or apply a warm towel to the nose for 10-15 minutes each time, 2-3 times a day. It should be noted that if there is a nasal congestion and runny nose, many people will instinctively blow their nose hard, thinking that this can help to ventilate faster. However, they may not realize that blowing their nose incorrectly may cause problems, especially when blowing both nostrils together, which is completely wrong. There are two common adverse consequences of blowing your nose incorrectly: one is that children are prone to otitis media, because there is a "small tube" (Eustachian tube) between the nasal cavity and the ear, which is short and straight. When catching a cold, the mucous membrane of the Eustachian tube swells and becomes blocked, creating negative pressure in the middle ear and accumulating secretions. When blowing the nose forcefully, the pressure in the nasal cavity can directly "press" the mucus and pathogens into the ear, causing otitis media. This disease is very painful, and children who cry in pain are often seen in outpatient clinics, which may also affect hearing. Secondly, elderly people may experience a surge in blood pressure. For those with underlying diseases such as hypertension and arteriosclerosis, blowing their nose forcefully can cause sudden changes in pressure in the chest and blood vessels, leading to vasoconstriction, temporary increase in blood pressure, dizziness, headache, and even danger. The correct steps for blowing your nose are: take a soft tissue, gently press one nostril, exhale gently through the other nostril, and blow your nose out. Don't use too much force, just blow it out. Then switch sides and repeat this step. After blowing your nose, wash your hands to avoid getting the virus on them. If the child doesn't know how to do it, parents can use a nasal cannula to help, and don't let the child blow it hard on their own. In addition, when the nasal congestion is severe, the mucus is too thick to blow out, accompanied by nosebleeds or nasal mucosal damage, and there are underlying diseases such as hypertension, heart disease, cerebrovascular disease, etc., it is advisable to avoid blowing the nose forcefully and seek medical help if necessary to avoid worsening symptoms and prolonging the course of the disease.
