Dr. Katie To explains why a warm salt-water gargle each morning clears post-nasal drip and biofilm from your throat. Swallowing that biofilm introduces unwanted microbes to your gut, but spitting it out after rinsing reduces microbial load and supports a healthier microbiome. It costs nothing and takes seconds.
One thing I would say I do every single day, and it's something that you can stick for a lifetime, is salt water. Growing up, my parents always said, first thing you wake up, you do warm salt water rinse, you gargle your throat, and then you spit out. Because a lot of people have postnasal when they wake up in the morning. Most people just swallow all the biofilm down to the gut. And so we have to thinking about those that doesn't cost money, doesn't change the microbiome. Bonus is living your best life without stress about how many steps you have to do every day. And how many supplements and how many things you have to like add on to your routine.
