In this episode, Mario and Max discuss the benefits of nasal breathing compared with mouth breathing. The key reason nasal breathing is superior is the production of nitric oxide (NO) in the nose. This molecule dilates blood vessels, particularly in the lungs, leading to better oxygen uptake and higher blood oxygen saturation. They discuss causes of obstructed nasal breathing and simple biohacks to improve it.
The main advantage of nasal breathing is the production of nitric oxide (NO) in the nose. This gas dilates blood vessels, improves blood flow through the lungs, and optimizes gas exchange. The concentration of nitric oxide in inhaled air can more than double when breathing exclusively through the nose, resulting in higher blood oxygen saturation, even with the same breathing volume as mouth breathing.
Many people unconsciously breathe through their mouths, often because of obstructions in the nose. These include swelling of the nasal lining due to colds, allergies, or alcohol consumption. Anatomical features such as enlarged nasal turbinates or a deviated septum can also make nasal breathing persistently difficult.
Various aids can be used to support nasal breathing. Nasal strips placed on the front, cartilaginous part of the bridge of the nose mechanically pull the sides of the nostrils outward, making airflow easier. For colds or allergies, decongestant horseradish nasal sprays and nasal irrigation can also help soothe the nasal lining and clear the nose.
A simple, free way to boost NO production is to hum as you exhale through your nose. Studies suggest that this can increase NO release many times over. Another technique is mouth taping, which involves taping the mouth shut at night to prevent mouth breathing. However, caution is needed, particularly if you might have undiagnosed sleep apnea.
Breathe through your nose instead of your mouth? Mario and Max explain how nasal breathing more than doubles the release of nitric oxide, thereby noticeably increasing oxygen saturation in the body. They also explore how nasal strips, mouth taping, and nasal rinses can help with blocked airways.
Take a warm shower in the evening to cool down and fall asleep faster? Mario and Max explain the physiological process behind vasodilation and how a controlled drop in core body temperature can improve sleep efficiency. They also reveal why timing is crucial—and why just ten minutes in the sauna can be enough.
If you struggle to get out of bed in the morning, a lack of natural light indoors may be the reason. In this biohack, Mario and Max explain how daylight can increase morning cortisol levels by up to 40%—and why regular bathroom lighting simply isn’t enough.
Cold showers in the morning for better focus and fat burning? Mario and Max debunk myths about brown adipose tissue, explain how cold actually affects the nervous system, show how box breathing helps during ice baths, and explain why people who take cold showers get sick less often.
