Hi Poulpe:
Nitrogen (azote) Absorption
There is considerable debate about this. Generally, it is thought that colder temperatures cause an increase in nitrogen absorption in the body. This is primarily because of blood flow. If the temperature is low, the body will send blood to the limbs to keep them warm. If the temperature is very cold, the body will attempt to save heat by not sending blood to the arms and legs. Diver movement to help keep warm and shivering will both increase blood flow and increase nitrogen loading.
Thus, depending on how cold it is, we can see opposite effects.:cold:
Warm temperatures, on the other hand, have generally been thought to be protective for DCS. In addition, the warmer the temperature of the water, the less nitrogen will dissolve. This is the opposite of most substances. For example, if you wish to dissolve more sugar in water, you bring the water to a boil. If you wish to remove nitrogen from water, then you boil it.
