Your heart’s capacity to support an elevated blood output decreases with age and with disease.Active warming during dives increases inert gas uptake. Being cold at the end of a dive traps inert gas.

Why can divers only dive for 10 minutes?
Divers can only spend around 12 minutes under water at a time to help avoid decompression sickness. Decompression illness symptoms generally begin within 6-48 hours after diving.
