Hello readers:
Sleep and Off Gassing
This is a finding that derived from my NASA-based research (on gas exchange and EVA). When we are inactive, the heart rate slows and the circulation throughout the body (with the exception of our brain) is reduced to its lowest level. Since perfusion (blood flow) is the mechanism by which dissolved nitrogen is eliminate from tissues following the dive, you want to have the greatest degree of blood flow possible.
Sleeping is the exact opposite of what you want in this regard. Some degree of activity is very useful, such as moving your arms and legs. Some amount of walking is permissible since tables were developed in walking subjects), but strenuous activity is to be avoided since it appears to promote the development of tissue micronuclei (microbubbles that grow with inward diffusion of nitrogen).
DCS and Sleep
In addition to dissolved nitrogen exchange, a sleeping diver is unaware of any change in the body especially neurological conditions. It is important that divers watch a too-quiet buddy and see that s/he has not experienced neurological DCS.
Arterialized gas bubbles can go to the brain and the result can be a diver who is not fully cognizant of the situation that has developed. :280:
Several responders have already pointed this out.
