Sleepy After Eating, Falling Asleep and Tired After Meals: Low Body O2

Effects of overbreathing on brain oxygen levelsFor most modern people, sleep generates the most negative impact on personal breathing and body-oxygen levels. The next most detrimental factor is eating, in particular, overeating leading to sleepiness after meals and naps after eating. Any person can easily prove the powerful negative effects of overeating using the body oxygen test.

It is common that body-oxygen test results are reduced by 20-40% or by about 5-10 seconds due to heavy breathing or hyperventilation. In addition, many people get sleepy after eating and even drowse into a nap after a meal, especially a large meal such as lunch or supper.

What are the causes and mechanism? In this video interview below, Dr. Artour Rakhimov explains causes and treatment for being sleepy after eating. Why do people need napping after larger meals even for 20-30 min or more?

Changes in breathing during last 100 years explain sleepiness after eating

Sleepy and tired after eating, with food in the stomach

Sleepy After Eating, Falling Asleep and Tired After Meals: Low Body O2 When food is still present in the stomach and the person overeats, overeating produces a biochemical shock on the whole organism due to factors related to heavy breathing. Falling asleep and tired after eating (usually in 20-60 minutes after eating) are frequent signs of this biochemical shock.

This effect of having sleepiness after eating with naps due to large meals is much stronger after eating junk food and especially overeating (see the second half of this page for more info about this effect). We start to generate free radicals, which cause oxidative stress or damage to the cells when the body oxygen levels drop below 20 seconds (see the link to the test below).

The solution to this problem is to chew food very well (to prevent overeating) or to eat half of the meal and wait for 20 minutes, waiting for signs of hunger. For nearly all people, their hunger disappears and they feel fine.

Falling asleep and tired when the food is gone from the stomach

If sleepiness takes place some 1.5-2.5 hours after meals (not immediately), it can indicate Candida yeast overgrowth in the small intestine (especially if a person has digestive symptoms, such as greasy stool, offensive gas, and so forth, see digestive health for details), or lack of sleep or deep stages of sleep (including sleep apnea).

The best remedy for such cases is to avoid simple sugars and fruits (if you have an excess of Candida yeast in the gut) and to do a simple breathing exercise that is explained in this video. The title says that this exercise is for people with anxiety. However, it works fine to get energized and alert in 1-2 minutes!

How overbreathing causes obesity

Person gets epilepsy during sleepThis effect (feeling sleepy after eating) is even more common in overweight people. Both signs (obesity and getting sleepy after eating) indicate ineffective breathing (breathing too often and too much air per one breath) at the same time. The solution to this common problem for obese people is to practice reduced breathing to increase body oxygenation. Any time an overweight person eats complex carbohydrates or fats, his body-oxygen levels and breathing immediately become much worse. Furthermore, hunger for starches and fats indicate a state of stress and lower body-oxygen content with a higher heart rate. This causes people to feel sleepiness after eating meals and take naps for more than 10 minutes (that is generally unhealthy unless one sleep-deprived).

Why and how can hyperventilation cause obesity? According to Professor KP Buteyko, MD, Ph.D., and research conducted by Russian medical doctors, CO2 is also responsible for the control of membrane permeability of fat cells. When we hyperventilate, due to low CO2, glucose is driven from the blood into fat cells, and the blood-glucose level naturally becomes low due to hyperventilation alone. Since glucose is crucial for the brain and well-being, it is sensible to eat in a manner that increases blood sugar levels up to the norm. Eating more intensifies respiration and this leads to the formation of a vicious circle:
– hyperventilation drives glucose into fat cells
– the person gets hungry
– he eats more and …
– hyperventilates more.
Hence, over 70% of people “naturally” gain weight when they hyperventilate. And low brain and body-oxygen levels are the expected effects of overbreathing.

People with low body O2 naturally dislike exercise, while high body O2 commonly means craving for and joy of exercise. But there is one crucial health tip that less than 1% of exercising people use. This tip is provided below in the bonus section.

These are the most natural methods or techniques to lose weight and increase body-oxygen levels. Moreover, breathing less makes obese people more alert and more energetic. All these factors make breathing retraining more meaningful than other weight loss techniques.

Permanent solution for feeling sleepy and tired after meals problem

If you feel tired or sleepy after meals with taking naps later, this means that your current body oxygenation is less than 20 seconds. You need to increase your brain and body-oxygen content up to a certain level (measured in seconds) so as to have much more energy and a clear mind 24/7 naturally. Find out this criteria and requirement as your bonus content right below here.

1. Physical exercise with only nasal breathing is a great way to fight fatigue, obesity, and extract maximum benefits from exercise. Exercise with mouth breathing often makes people feel worse. and it is unsafe in relation to acute exacerbations.
