Today a missed a freediving session due to sinus pain and congestion. Usually in the case I get out the neti pot and do stream treatments with some essential oils; that is, I tend to be reactive. But I wonder if there is a way to be more proactive -- some natural sinus and ear care routine that would help prevent this in the first place. Does anyone have any advice or techniques that work for them? What kind of treatments do you do, how often, and how well do they work?
