Why Do People Experience Low Oxygen at Night?

Because we breathe less when we sleep, our blood oxygen level drops. Our alveoli may also function slower when we sleep. As a result, some people experience low oxygen levels at night. 

People with sleeping, breathing, or respiratory health disorders, such as COPD, sleep apnea, and asthma may also suffer from this situation. 

Signs & Symptoms of Low Oxygen While Sleeping At Night

The average oxygen level for people ranges from 90 to 100%. Once your oxygen level drops down to 88% and below, you must immediately consult your trusted respiratory therapists.

However, it is reasonable if you cannot measure your oxygen level during sleep. Instead, you may encounter signs and symptoms that indicate low oxygen while sleeping at night. These are as follows:

  • Waking up gasping for air or choking
  • Confusion or disorientation
  • Chest pain
  • Vision problems
  • Restlessness
  • Dizziness, drowsiness, or fatigue during the day
  • Rapid breathing or shortness of breath
  • Increased heart rate
  • Loud snoring
  • High blood pressure
  • Anxiety or depression for no reason
  • Memory loss or trouble remembering events
  • Bluish tints in ears, nails, and lips

5 Ways to Increase Oxygen Levels While Sleeping

Luckily, you can follow five essential tips to increase your oxygen levels while sleeping. This list includes improving your lifestyle, managing air quality, and using breathing equipment. Read the following to know more.

1. Daily exercise

First, doing daily exercises can improve your sleep duration and quality. It straightens your lungs, leading to more oxygen, increased lung capacity, and better performance. Moreover, it also enhances your immunity and endurance.

We recommend doing aerobic exercises, such as walking and cycling.

2. Improve air quality

You can keep the window open all night to have fresh ventilation. Using an air purifier may also help. Additionally, you can put various houseplants that remove toxins and produce oxygen inside your place. These houseplants may include peace lilies, chrysanthemums, golden pothos, Chinese evergreen, spider plants, etc.

3. Solve sinus problems

Another way to increase oxygen levels is to solve your breathing problems due to nasal congestion. You can clear your airways by using counter allergy medications, nasal sprays, or neti pot (for not more than three times a day). 

4. Do not sleep on your back

You may opt to sleep sideways to relieve the weight on the airways and lungs. It can improve ventilation for better breathing. Furthermore, it helps remove obstructions and decrease snoring.

5. Use portable oxygen concentrators

Lastly, an overnight portable oxygen concentrator gives you supplemental oxygen during sleep. It maintains your average oxygen level.

Portable oxygen concentrators have different brands, models, flow types, and rates, allowing you to choose which one suits your breathing condition. Nonetheless, you will still need to get a prescription from your respiratory therapist.

2. Nose dryness

Do not get alarmed by nose dryness because most people using portable oxygen concentrators can experience this due to the drying effect on nasal passages. Consequently, you can also suffer nose bleeding from nasal dryness.

3. Skin irritation

Due to dryness, your skin may also break down, leading to skin irritations. It is usually because of the cannula rubbing against your skin when using portable oxygen concentrators.


Skin irritation somewhat relates to nose dryness. You may also use moisturizers to lessen the dryness and give lubrication to your skin. 

4. Use the appropriate oxygen rate

When using a portable oxygen concentrator, inappropriate oxygen rates may harm your heart, lungs, and brain. It may also lead to oxygen toxicity.

Aside from that, high oxygen levels may increase radical formation, leading to mild to severely damaged lungs. You may also get different lung diseases, such as mild tracheobronchitis and diffuse alveolar damage.


You can go to your nearest respiratory therapist to perform an arterial blood gas (ABG) test or oximetry. This test will let you determine your oxygen flow rate by measuring your oxygen levels in the blood. After this, your therapist may prescribe what flow rate you should have.

5. Portable oxygen concentrator maintenance

Due to the constant usage of portable oxygen concentrators every day, some may encounter damage and wear, especially when you do not perform regular maintenance. This situation may lead to further machine errors that may cause an inability to use it.


We advise doing inspections daily or a few days a week. You can also clean the filters to ensure that they do not become clogged with dirt. Please follow the maintenance instructions provided on your machine, if there are any.

6. Battery life

It can be slightly annoying to have your oxygen concentrator drained when using it since you will be forced to stop and let it recharge for a while. This situation can be harmful to people who need emergency oxygen supplies.


Ensure always to check the battery life. Most portable oxygen concentrators have LCDs to see the status of your machine. You can also opt to use double batteries to have longer battery life.

7. Use the machine with caution

Some people need to use portable oxygen concentrators daily for a constant oxygen supply. Those with low oxygens while sleeping may also become required to have oxygen therapies 24/7. Therefore, it is advisable to use the machine with extra caution and ensure correct usage to avoid complications.


Follow your respiratory therapist's prescriptions to avoid oxygen toxicity and achieve the best outcomes. 

8. Maintaining the position of the cannula or oxygen mask

The rubber on your nasal cannula or mask may scratch your skin. Furthermore, the nasal prongs may also brush inside your nostrils, which can be uncomfortable and painful.


First, you can wrap the rubber in white first-aid tape to ease the pain whenever it scratches your skin. Also, ensure that the cannula or oxygen mask fits comfortably around your mouth and chin.
