7 Ways to Naturally Boost Nitric Oxide in Your Body
Did you know that nitric oxide (NO) is often called the "molecule of cardiovascular health" or even the "molecule of life"?
Nitric oxide is a powerful compound with antibacterial and antiviral properties. Crucially, it's also a vasodilator, meaning it relaxes and widens your blood vessels. This process begins in the nasal cavities, which is a key reason why breathing through your nose is so fundamental to good health.
But it's not just your nose. The cells lining your blood vessels (the endothelium) can also produce nitric oxide. This remarkable substance allows your body to control blood flow to every single part of your system. The discovery of this mechanism was so significant that it led to the development of medications for high blood pressure and even the famous drug Viagra. For this breakthrough, pharmacologist Dr. Louis Ignarro was awarded the Nobel Prize in Medicine.
As a vasodilator, NO plays a critical role in your overall health. It helps prevent the formation of blood clots that can cause heart attacks and strokes, regulates blood pressure, reduces the buildup of plaque in arteries, lowers cholesterol, helps prevent diabetic complications, and even improves memory.
So, how can you naturally increase the levels of this vital molecule in your body?
1. Breathe Through Your Nose
Your nose is designed for breathing; your mouth is for eating and speaking. When you breathe through your nose, the breath is naturally slower and deeper, directing air to the lower lobes of the lungs. This is followed by a slow, controlled exhalation.
The higher the quality of your breath, the longer the natural pause will be after you exhale, before you feel the need to inhale again. This very pause allows nitric oxide to be produced in your nasal cavities. If you breathe quickly and shallowly, you rob yourself of this essential process. It's also crucial to breathe through your nose while you sleep, as this significantly contributes to your body's regeneration and recovery.
2. Practice Breath Holds
Holding your breath is another powerful way to give your body a direct signal to produce NO. Even a few seconds of holding is enough for your body to release a shower of nitric oxide and other beneficial substances.
- Gentle Repetitions: Extend your exhale, and at the very end, gently hold your breath for a count of 2-3 seconds. The hold should only be long enough that your next inhale can remain soft and gentle. Repeat this cycle for 5-6 minutes. You can take 1-2 normal breaths between holds as needed.
- Longer Holds: Another method is to hold your breath after an exhale for as long as your body can comfortably tolerate while gently swaying your head from side to side. Follow this with a slow, gentle inhale and several normal breaths. Repeat this 5 times.
Note: Pregnant women should not practice breath holds.
3. Hum, Murmur, or Chant "Om"
When you hum or chant "Om" with your mouth closed, you can increase the production of nitric oxide in your nasal cavities by up to 15 times! That's a significant boost. As an added benefit, these vibrations activate your parasympathetic nervous system, which helps calm your body and mind.
4. Try Cold Exposure
That's right—even chilling your body can trigger a massive increase in nitric oxide. The constriction of tissues from the cold is followed by a powerful vasodilatory response. But a word of caution: not everyone's constitution is suited for cold therapy, and like anything, it should be approached with common sense.
This reminds me of Vincenz Priessnitz, a 19th-century pioneer of hydrotherapy, who was truly ahead of his time with his treatments involving cold wraps, fresh air, and movement.
5. Eat Nitrate-Rich Foods
Your diet plays a huge role in NO production. Focus on foods rich in natural nitrates, such as:
- Spinach
- Beets
- Celery
- Arugula
- Lettuce
- Carrots
- Parsley
- Radishes
- Almonds
Raw Cacao is another excellent choice, as it's packed with antioxidants and polyphenols that significantly influence nitric oxide production.
Garlic and Vitamin C: A powerful combination. In one study, participants were given 2 grams of vitamin C along with 4 tablets of aged garlic extract for 10 days.
The results were astonishing:
- NO production increased by an incredible 200%.
- Systolic blood pressure decreased from an average of 142 mmHg to 115 mmHg.
- Diastolic blood pressure decreased from 92 mmHg to 77 mmHg.
6. Get Some Sunlight
Researchers at the University of Edinburgh discovered that when sunlight comes into contact with the skin, nitric oxide is immediately released into the bloodstream. This process can help lower blood pressure and reduce the risk of stroke later in life.
7. Move Your Body
Finally, don't forget to move. Exercise improves blood circulation and helps deliver oxygen to your cells, both of which are essential for optimal health and NO production. You can learn more about how to breathe correctly during exercise in this article here.
I am truly fascinated by all the intricate connections within our bodies. So straighten your posture and let your breath flow freely. You can learn more about functional breathing right here >>>.
