How does carbon dioxide affect us?

Carbon dioxide is expired from the body during normal respiration. If this poisonous gas is allowed to build up in the body it affects us in many negative ways.

1. Hypoxia is a lack of fresh oxygen in the breathing process. This causes a euphoric feeling that can be very dangerous. The overall feeling of well being through oxygen deprivation can cause a pilot to preform foolish acts. Similar issues have been reported by mountain climbers in this situation. The desire to just lay down in extreme weather or other poor decisions can be traced back to this situation.

2. Carbon dioxide buildup will trigger significant increases in the relative acidity of your blood and other body fluids. If this acidity continues, you can lose your normal lung function. If still left unchecked, you could develop shock, which can be fatal.
