The Importance of the Element Oxygen

Oxygen is a gas that we usually take for granted, but it's a life-sustaining element that can be found almost everywhere on Earth. Without it, human beings and most other living organisms would not be able to survive for long. The human body cannot remain functional for even a few minutes without oxygen present in the surrounding environment. This article explores how much oxygen the body needs, where it can be found, and why this element is so important.

How Much Oxygen Does the Body Need?

The precise amount of oxygen needed by the body varies from person to person, but the general rule of thumb is that a healthy adult needs between 19 and 21% oxygen in the air. When the amount of oxygen in the air around us falls below this level, our bodies experience a range of symptoms including dizziness, headaches, fatigue, and difficulty thinking clearly. These symptoms can develop into something more serious if the oxygen levels drop further, so it’s important to be aware of the signs of low oxygen and take action to increase it.

Where Does Oxygen Come From?

The oxygen we need for survival is found in the air around us, as well as in some of the food we eat and some of the liquids we drink. When gas travels from the air into our bloodstream, it is absorbed through the alveoli in the lungs. These are tiny sacs that are surrounded by blood vessels, meaning that oxygen from the air can easily be transferred into the bloodstream. As the blood travels throughout the body, it carries oxygen to dead tissues that need it.

Why is Oxygen so Important?

Human beings cannot live without oxygen for long, but it’s not just our survival that’s at risk. When the amount of oxygen in the blood drops, it can lead to a condition called hypoxia. This is a serious issue that can lead to organ damage and even death if it goes untreated. When oxygen levels drop too low, the body must rely on an alternative source of fuel instead of oxygen. This can be dangerous because many of the chemicals the body uses as fuel are toxic and can damage organs.

The Importance of Red Blood Cells

Blood is a complex network of vessels, cells, and plasma that transfers oxygen to the body’s tissues. Cells called red blood cells to make up the majority of this blood and are responsible for transporting oxygen throughout the body. When blood travels through the lungs, it picks up oxygen that it then delivers to different organs around the body. In the process, it also picks up carbon dioxide and other waste products, which it then carries back to the lungs to be released into the air. Red blood cells are responsible for around one-third of the oxygen found in the bloodstream.

3 Ways to Increase the Amount of Oxygen in Your Body

There are a few different ways you can increase the amount of oxygen in your body and help it fight against the effects of low oxygen. It’s important to be aware of the signs of low oxygen so that you can take action before it’s too late.

- Breathe through Your Nostrils - When you breathe through your nostrils, you can control the amount of oxygen that enters your bloodstream. By only breathing through one nostril at a time, you can increase the amount of oxygen in your body.

- Exercise - Regular exercise helps to increase the amount of oxygen in your body by increasing your heart rate and blood flow. This is particularly important if you are experiencing symptoms that may be caused by low oxygen.

- Drink Water - Hydrating your body with water can help to increase the amount of oxygen in your bloodstream. Drinking plenty of water can also reduce the risk of dehydration and improve your general health.


The human body needs oxygen to function properly, but it’s important to remember that we can only access oxygen in the air around us. Oxygen delivered through breathing, eating certain foods, and drinking certain liquids can help the body to fight against the effects of low oxygen and remain healthy and alive. When oxygen levels are low in the air, there are a few things you can do to increase the amount of oxygen in your body and keep your organs healthy and your mind clear. Remember that oxygen is important for more than just survival, it is also critical for many other bodily functions.
