The very first lesson you will learn in diving is to breathe slowly and continuously, never holding it. The theory sessions will remind you over and over of how important that is to breathe. Slowly. Continuously.
It’s kind of worrying, to be frank. They showed a wide range of risks related to breathing only. Be it the air quality in the tank, the failure in the regulators, the descending and ascending techniques, and a little bit of physics from high school that suddenly bothers you again, hehe.
Equalizing is a very important method you need to master. You will experience change of pressure gradually and repetitively when you go up and down underwater. Do it as often as needed, that’s when you feel even a slight discomfort in your ears. Don’t inderestimate equalizing. Ignoring this simple step could seriously damage your ear. It’s always wiser to be careful.
So that’s the story for today. When you’re not underwater, you could still apply the theory. Keep breathing. Slowly. Continuously. It surprisingly will calm you down.
