Which describes a regular breathing pattern while diving?

• A. Faster and shallower
• B. Very irregular
• C. Slightly slower and deeper than you normally breathe
• D. Same rate and depth as on land

Answer: (C)

Regular, controlled breathing is essential underwater. The best description is slightly slower and deeper breaths than you normally take on land. Slower, deeper breathing uses each breath more efficiently, conserving air and helping keep your buoyancy steady as lung volume changes with depth. It also reduces the chance of CO2 buildup and keeps you calm, which is important for staying relaxed and focused during the dive. Breathing faster and shallower wastes air and can cause buoyancy and gas-exchange issues, and breathing the same as on land doesn’t account for the underwater environment.
