you probably heard about drowning but have you heard about secondary drowning I work at a first aid post at one of the busiest beaches in Belgium it's obvious when you're drowning you can't breathe and you're breathing water and we're not fish so that doesn't work out for us there is a substance in your lungs that's called surfact and it helps with a transport of oxygen and CO2 in out your body but when you breathe in water that surfactant gets washed away and that makes it more difficult to do that transport of oxygen and not enough oxygen in your lungs can lead to brain damage or even death if left unchecked so go see your doctor subscribe for more
