why is nitrogen builds up into your system
Nitrogen buildup in your system can occur in various contexts, but the most common and potentially dangerous situation is related to scuba diving. When diving, you breathe compressed air, which typically contains about 78% nitrogen.
As you descend underwater, the increasing pressure causes your body to absorb more nitrogen. This dissolved nitrogen is carried by your circulatory system to various tissues, including muscles, blood vessels, and organs. During the dive, the nitrogen remains dissolved and does not cause harm.
However, if you ascend too quickly during the dive or stay at depth for extended periods, the gradual increase in pressure causes the nitrogen to come out of solution and form bubbles. This process is known as decompression, and the resulting condition is called decompression sickness or "the bends."
The symptoms of decompression sickness can range from mild inconvenience to life-threatening conditions. They include joint and muscle pain, fatigue, dizziness, shortness of breath, skin rashes, and, in severe cases, neurological symptoms.
To prevent nitrogen buildup and decompression sickness, scuba divers use dive tables or dive computers. These tools calculate the maximum allowable dive times and depth limits to minimize the risk of nitrogen accumulation. These limits vary based on factors like the depth of the dive, bottom time, and previous dives. By following these guidelines, divers can safely eliminate excess nitrogen from their bodies during a gradual ascent.
It's essential to carefully monitor dive profiles, follow the recommended dive plans, and allow for proper decompression stops during ascent to prevent nitrogen buildup and avoid any potential risks associated with decompression sickness.
