Many of us are suffering from lots of lifestyle diseases. Among them is the blood oxygen levels. People are looking at how to increase blood oxygen levels1. People spend more money to treat this lung disease. Many natural ways can also be followed to increase the blood oxygen level.

The variation in the oxygen saturation or oxygen levels may lead to dangerous situations. How to increase blood oxygen level is a popular question in today’s lifestyle. People are not bothered about the upcoming consequences their has to face in their life.

1. What Does a Blood Oxygen Level Mean?

In simple words, we can explain the amount of oxygen present in our blood. It can be measured in the easiest way using the pulse oximeter readings. There must be certain measures of oxygen to be maintained in our blood otherwise it leads to various diseases. Many breathing problems will be faced lifelong.

In order to function properly there must be a constant amount of oxygen in the blood. The oxygen breathed into the lungs is passed through the bloodstream and circulated through the body in the red blood cells. This oxygen reaches all parts of the body and makes the normal range of blood oxygen level.

The proper balance of oxygen saturation is needed for the proper balance of the body. Beyond medical conditions, the blood oxygen level may vary due to our environment. The emission of carbon dioxide in the atmosphere results in a variation in blood oxygen levels and seems to have difficulty breathing.

2. What Should Be a Normal Blood Oxygen Level?

A small machine helps us to measure the oxygen saturation level2 or blood oxygen level, it is named a pulse oximeter. A pulse oximeter reads our blood oxygen level by shining a light through the capillary veins near our skin’s surface. It is normally referred to in percentage or shown in the form of SpO2.

During the blood test, we can determine the amount of oxygen present in the blood sample. Normal blood oxygen level ranges from 95 – 100%. It is seen lower in people suffering from lung diseases or chronic obstructive pulmonary disease.

The low blood oxygen levels are seen below 90%, and they must seek medical attention. Trouble breathing is the main symptom seen in those people. The varying body temperature can also help us to find the function of oxygen in the blood.

The blood oxygen level below 90% is quite low and it is quietly seen in the cases of COVID -19 situations. Low blood oxygen level is a serious symptom seen in COVID-19 patients. Pulse oximetry must be always checked in these people otherwise even death may happen. In aged people, lung capacity will be very low. So their blood pressure and blood oxygen level will vary in their blood test.

In normal cases, all must have the right knowledge of how to increase blood oxygen levels. There are many easier ways to increase blood oxygen levels through food and exercise. The blood oxygen saturation must be on the same path to be healthier. The red blood cells are the area where oxygen is transported through blood it acts as a medium.

3. How to Increase Blood Oxygen Level: 6 Simple Ways for That

The overall blood oxygen level must be balanced for the functioning of the body. Many breathing exercises, food, breathe fresh air, and some physical activity helps to increase oxygen levels. A healthy person has a normal blood oxygen level. So, that person has proper body functioning and a smooth respiratory system.

9 Ways to Increase Blood Oxygen Levels Naturally | How to Increase Oxygen Level in Body

Shortness of breath indicates that person is suffering from a low blood oxygen level. Iron-rich foods can also, maintain the oxygen level. How much oxygen passed through the blood indicates the level in pulse oximetry. Without medicine, we can increase the blood oxygen level. We can achieve the typical blood oxygen level through these natural ways.

Oxygen therapy 3is also available in this situation of low blood oxygen levels. Blood oxygen saturation must be balanced to get a rapid breathing procedure. The amount of oxygen needed for the body must be maintained to a great extent. The pulse oximeters must be pointed at 100% while checking the oxygen level.

There are many ways to increase blood oxygen levels naturally. Instead of taking too much of medicines, the supply of blood through red blood cells can be increased by simple home procedures. Blood oxygen saturation determines the amount of oxygen present in the blood.

There is no need to spend too much money or make drastic life changes to enhance the amount of oxygen in the blood. You must have simple lifestyle changes and follow healthier habits to gain success in this case. Below mentioned are the simple ways to increase it.

3.1. Exercise

To ensure the supply of oxygen level in the blood regular workout is important. While doing regular exercises, the cells in the body burn oxygen more than before. the level of carbon dioxide in the body increases, the brain increases the respiration rate to get more supply of oxygen.

The lung and heart perform at optimum capacity while taking exercise to intake more oxygen supply. People suffering from low oxygen saturation can feel a great change while doing regular workouts. This is the simplest remedy for the question of how to increase the blood oxygen level.

3.2. Getting Fresh Air

Another simple way to get good oxygen levels is by breathing fresh air. It can be created in our home itself. Something as simple as opening the windows or taking a walk through the fresh atmosphere enhances the flow of more oxygen through the blood and increases oxygen levels.

Care should be taken to make sure that unwanted gases like carbon dioxide or carbon monoxide are inhaled into the lungs as your walk through the dirty atmosphere. In a clean atmosphere, deep breaths can be taken as it is a free oxygen supply naturally.

3.3. Quit Smoking

Another reason for low blood oxygen is the people’s habitat of smoking or intake of alcohol. The blood ph will be affected and affect the lung tissue and get damaged. People with these habitats have spongy lungs that can be destroyed easily. That is the reason why all are advising that “alcohol or smoking is injurious to health.

After only two weeks of being smoking-free, people understand that their circulation and blood oxygen levels improve significantly. It will be magic for your life to be in a stable condition and free from lung disease. Also, increase your blood oxygen normally by yourself.

3.4. Grow Some Plants

House plants will help to purify the air indoors. They remove carbon dioxide and fill the atmosphere with oxygen which is needed for our bodies to breathe. Hence we can inhale fresh oxygen from our homes itself. There are many plants available in the market that can be placed indoors to gain a fresh breathing atmosphere. How much light do the pants absorb helps us to absorb more o2. How to increase blood oxygen level can be maintained through this method.

3.5. Practice Breathing Exercises

Simple breathing exercises help us to attain stable conditions. The doctors themselves recommend pulmonary oxygen therapy or exercise like pursed lip breathing, and deep belly breathing to increase oxygen supply through blood. Through this blood pressure also can be maintained. Slow breathing techniques can also be practiced. Inhale slowly can also be treated here.

3.6. Through Food

Food also plays a vital role in increasing blood oxygen levels. Enough oxygen needed for the cells can be gained through food. Food that is rich in iron and nitrates is the key to increasing the oxygen supply through the body. Antioxidant-dense foods are also a reason to improve the oxygen flow through the blood.

Green leafy vegetables and fruits are also good for this function. We must remember to eat iron-rich foods for getting enough supplemental oxygen. The antioxidant food includes:


  1. Garlic



  2. Dates



  3. Carrot



  4. Bananas



  5. Spinach



  6. Lemon


These food have a ph value of 8 that boosts oxygen naturally. Lemons are the top oxygen-rich food that is acidic outside the body and turns alkaline within the body. So these types of vegetables and fruits must be included in your daily diet to maintain blood oxygen levels. It is the remedy for how to increase blood oxygen level

3.7. Drinking Plenty of Water

The next tip to increase oxygen saturation in our body is hydration. When you drink a lot of water, your lungs remain hydrated and improve the process of oxygenation. Thus it helps in oxygen monitoring. All this leads to getting rid of other gases and releasing oxygen to the body. In order to maintain it drink at least 2- 3 litres of water a day. We can easily answer the question of how to increase blood oxygen level from this.

Final Note

From this above article, you will be able to read out the techniques and ways needed for the question of how to increase the o2 level. By following the above methods we can improve it naturally. The difficulties in shortness of breath and sleep apnea can be slowly cured by these procedures. Here you can get the result for how to increase blood oxygen level.

In some pandemic situations, we can ask for medical help. Otherwise, we can cure it from our home itself. Medical treatment prefers strong pain medications which just be carried lifelong. So be in mind the food items and liquid forms to get good readings in pulse oximeters4. You can identify the changes by yourself.
