What is the golden rule of scuba diving?
1. Never hold your breath. This is undoubtedly by far the most crucial of all safety rules for diving because failure to adhere could result in fatality. If you hold your breath underwater at the depths at which scuba divers reach then the fluctuating pressure of air in your lungs can rupture the lung walls.
Can you scuba dive with braids?
A braided ponytail works well, but a french braid is even better. In either case, leave hair braided until after the dive. Rinse hair with fresh water before undoing the braid, and gently detangle.
Why do scuba divers cross their arms?
Simply to keep them out of the way. You shouldnt need/use your arms whilst diving. Your lungs control bouyancy.
