Im an aerial photographer and im in the air quite a bit. Ranging 0-10,000ft
Wondering about going from negative to positive pressure and vice versa when freediving/spearfishing.
Bound to have some medical affects?
Not really diving much depth yet it all but just curious of anyone is involved in similar conditions or knows?
