First, whether it is harmful to the body.
Non-iodized salt water, namely physiological saline, is made of non-iodized salt+water. The best ratio is 500 ml of water and 4.5 g of salt, and the concentration is just 0.9%. Generally, non-iodine salts used for nose washing are salts without any additives, which are harmless to the body.
There is also iodized salt to wash the nose. Too much iodine absorption can easily cause damage to organs such as thyroid gland, so you can't wash your nose with iodized salt. Because the capillaries in the nasal cavity are very rich, the ability to absorb drugs is similar to that of intramuscular injection, which is harmful to the body.
Second, the difference between non-iodized salt and iodized salt.
Non-iodized salt refers to edible salt without iodide, which is mainly eaten by people in iodine-deficient areas. Non-iodized salt can control excessive iodine intake and eat non-iodized salt. In medicine, non-iodized salt is used to wash the nose with salt water. Non-iodized salt hyperthyroidism patients should eat non-iodized salt. When cooking, add salt first, then put vegetables, and iodine volatilizes when heated.
Iodized salt refers to sodium chloride salt containing potassium iodate, mainly in iodine-deficient areas. Iodized salt can promote energy metabolism and promote children's physique and brain development. When cooking with iodized salt, add iodized salt instead of too much vinegar. Even if you buy less and eat in time, iodine will easily play a role after a long time.
Extended data:
1, you can try to clean the nasal cavity with light salt water, but warm water is still needed. If the symptoms are still not relieved, it is best to go to a regular hospital for further examination, confirm the cause and give targeted treatment. It is best to use normal saline, that is, 0.9% sodium chloride injection, instead of iodized salt we eat.
2. It is no problem to wash the nose with iodized salt in the short term, and it is easy to get iodine poisoning when washing the nose for a long time. So it's best to use non-iodized salt. The mixing ratio is 500ml of water and 4.5g of salt, and the mixing concentration is only 0.9%.
3. According to the description of sinusitis, it is suggested to use budesonide nasal spray, Biyuanshu oral liquid and amoxicillin capsules to promote recovery by oral administration, avoid spicy food and do not wash your nose with iodized salt.
