Immune tip no 5 - Use a neti pot when you have a cold

 One study found that a daily saltwater nasal rinse may be beneficial for colds. The participants who used saline nasal rinses (six times per day initially and TID during the rest of the 12-week study) had fewer nasal and throat symptoms, they were healthier, and fewer of them used medications to manage their symptoms than those who did not use the rinses. The nasal rinse was a standard 0.9% saline (sodium chloride) solution with trace elements and minerals in concentrations similar to those in seawater. (Sea Salt)

 Method:

Mix a pinch of salt and a pinch of bicarbonate of soda in about half a pint of warm water. Use a bulb syringe (a neti pot) to squirt water into the nose. Hold one nostril closed by applying light finger pressure while squirting the salt mixture into the other nostril. Let it drain. Repeat two to three times, then treat the other nostril.
