Nitrogen and Breathing
Nitrogen is a colorless, odorless and tasteless gas which makes up 78% of the Earth's atmosphere. It is non-toxic and is safe to breathe. In fact, it is essential to life. Oxygen is the most important gas we need for breathing, but nitrogen is also important in maintaining proper air pressure and providing the correct atmosphere for our bodies.
Hypoxia is a condition caused by a lack of oxygen in the body. It can be caused by altitude sickness or a lack of oxygen in the air. Nitrogen helps to prevent hypoxia by forming a buffer in the air. This means that nitrogen absorbs excess oxygen and prevents the oxygen levels in the air from dropping too low.
Oxygen Toxicity is a condition caused by breathing too much oxygen. This can be dangerous and can cause convulsions, seizures, and even death. But because nitrogen is present in the air, it helps to prevent oxygen toxicity by forming a buffer and preventing the oxygen levels from rising too high.
So, in conclusion, nitrogen is safe to breathe. It does not cause any harm to humans and is an important part of the air we breathe. It helps to prevent both hypoxia and oxygen toxicity, and is essential for maintaining the correct atmosphere for our bodies.
