I used to be sick with sinusitis every single year(especially winters) for approx. 8 years. I don't even want to count how many packs of antibiotics did I consume during that time.

One September, I started to shower myself with cold water at least once a day.

It's been 4 years now and I haven't taken a single antibiotic since.

It also has a great mental effect - doing something a bit uncomfortable every single day makes it easier to do something else that's also uncomfortable.
