Continuing heat loss associated with wetsuit diving mounts with each consecutive dive. After the first dive:

• Some skin/surface cooling.
• Skin reheats during rest period but leaves some subsurface cooling.

After the second dive:

• Additional diving re-cools the skin and increases level of subsurface cooling.
• Skin reheats during rest period, but subsurface cooling increases, affects comfort, and diving requires more effort.

On subsequent dives:

• Additional dives re-cool skin and add substantially to subsurface/body heat content drop.
• Reheating of the skin takes an extended amount of time. Body heat content drop causes increased fatigue and enjoyment ceases.
