Here is the YouTube video "Heavy breathing at sleep". This video clip has information and
quotes from medical studies, which are described above.
heavy breathing during sleep effect explains decades of medical research and clinical observations that sleep and especially early morning hours (4-7 am) are the times of highest mortality rates for asthma, angina pectoris, stroke, seizures, and many other conditions.
American pediatricians from the Washington University School
Medicine in St. Louis in their publication noted symptoms
related to bronchial asthma are often more prominent during sleep. These scientists found reduced lung function results (PEF and VEF) in the early
morning hours (Porter et al, 1999).
A group of Brazilian medical scientists investigated,
according to their title Morning-to-evening variation in
exercise-induced bronchospasm (Vianna et al, 2002). Their
objective was to test morning vs. evening exercise-induced
bronchoconstriction, as well as MV (minute ventilation) during physical exercise. The results confirmed that morning parameters were worse: FEV1 was significantly lower during early
morning hours, while minute ventilation was higher meaning heavier breathing through narrower airways.
Over 30 years ago the Thorax published a study: Physiological
patterns in early morning asthma (Hetzel, et al, 1977). The
goal of the study was also to explain the sudden nature of some asthma
deaths since, as these researchers discovered, these mortality cases often occur during early morning hours.
Several other publications were devoted to effects of sleep on
patients with COPD (chronic obstructive pulmonary disease). American
scientists from the Yale Center for Sleep Medicine (Yale University
School of Medicine, New Haven) wrote that COPD symptoms during sleep are common in patients with moderate and severe COPD,
especially in the elderly. They experience stronger hypoxemia (reduced oxygenation of the arterial blood). In conclusions, it was stated that sleep has "profound
adverse effects" on respiratory parameters and exchange of gases (oxygen and CO2 in alveoli) in patients with COPD
(Urbano & Mohsenin, 2006).
Moreover, Sheppard and colleagues in the publication from the
Chest magazine noted that epidemiologic research has revealed that
patients with COPD have higher mortality rates during
the early morning hours (Sheppard et al, 1984). The load on the heart
muscle during episodes of nocturnal hypoxemia, according
to their conclusion, can be "as great as during maximal
Coronary spasms and cardiac arrest
If patients with pulmonary conditions can die due to heart
problems at night, what about heart patients themselves? This team of scientists found that coronary artery spasm is most likely to occur "from midnight to early morning" when the person
is at the state of rest (Yasue & Kugiyama, 1997). This Japanese study was published in the Journal of Internal Medicine. The main and the only sleep-related variable and cause of these spasms is heavy breathing.
Intensive care professionals from the Department of
Anaesthesia and Intensive Care Medicine of the Hadassah Medical Centre
in Jerusalem, Israel also decided to investigate, according to their
title, In-hospital cardiac arrest: is outcome related to the
time of arrest?
These health professionals tried to find out if outcomes from in-hospital (CPR) cardiopulmonary
resuscitation is different when it takes place at night. It was concluded that resuscitation during night shifts have poorer outcomes (Matot et al, 2006).
from Ankara published a study with the goal to explain
morning increase of sudden cardiac death. Their hypothesis was based on the
role played by the sympathetic nervous system (Batur et al, 1999). It is known that sympathetic nervous system drives respiration or minute ventilation up, thus, causing tissue hypoxia induced by hyperventilation.
A group of American cardiologists from the Georgetown
University Medical Center in Washington, D.C. was also interested in
the most likely time of death in 96
of the 139 patients who died suddenly. They found a
distinct peak in death rates during morning hours (with high significance p = 0.04) (Behrens et al, 1997).
Swiss medical doctors stated in their study higher chances of the appearance of symptoms of Prinzmetal's angina during early morning hours. These researchers directly concluded, in their abstract (click the link below) that overbreathing could cause vasoconstriction of
coronary arteries (Jacob et al, 1994).
Even healthy people have heavier breathing and lowered
oxygenation of the brain during early morning hours, as Australian
scientists from Latrobe University in Melbourne revealed. After testing
health subjects, these scientists concluded that changes in CO2 (carbon dioxide) may be a
contributing factor that explains the
high incidence of cases of acute episodes and stroke in the morning (Cummings et al, 2007).
effects will cause symptoms of morning sickness fatigue or morning
headache fatigue with possible adrenal fatigue and high morning cortisol.
Cerebral ischemia and stroke
It is not a surprise then that British researchers from the
National Heart and Lung Institute (Imperial College, London) also
noted an increased risk
of cerebral ischemia and stroke in the morning possibly related to changes in CO2 reactivity, used as a provocation test (Meadows et al, 2005).
Similarly, Californian neurologists noticed this reduced
morning response to hypercapnia in patients with stroke. These scientists also observed the increased risk of exacerbations due to stroke during the morning hours (Ameriso et al, 1994).
Patients with diabetes also suffer from lower oxygenation in
tissues during nights. In one study, they tested 40 patients with
insulin-dependent type 2 diabetes. The measurements of tissue oxygen levels and blood rheological properties were investigated during different parts of the day. The study found reduced tissue oxygenation at night and disturbance of
hemorheological blood properties when a person with diabetes as sleeping (Galenok et al,
Japanese doctors from the Department of Pathology for the
Handicapped in Ehime University warn that those who care about people
with epilepsy should know about higher chances of seizures during
nights. They stated that s-w paroxysms (or seizures) combined with symptoms and lasting for over four seconds were less common during the afternoon rather than the
morning hours. But even higher chances of seizures were observed during sleep (Nagao et al, 1990). Since heavy breathing reduces blood
supply and oxygenation of the brain, while also making nerve cells
over-excited (due to a lack of CO2 that has calmative or tranquilizing nerve cell effects), it is sensible that epileptics are most likely to
experience seizures during sleep (early morning hours).
A marker of inflammation, C-reactive protein, was measured
during different parts of the day in obese patients (Punjabi &
Beamer, 2007). The conclusion of these medical scientists from the
Johns Hopkins University in Baltimore was in the title of their study: C-rеactivе
prCеtеin is assCеciatеd with slееp disCеrdеrеd brеathing indеpеndеnt Cеf
Hence, it is not just obesity, but disordered
breathing at night that can lead to inflammation due to SDB (sleep-disordered breathing).
Inflammation in the amnesic patients
Since inflammation can get worse during nights in many
patients, is it possible that cortisol production (cortisol is one of
the key hormones to fight inflammation) also decreases at nights?
In this study, a group of German researchers suggested that the expected (or normal) morning cortisol
increase, due to circadian changes, is not present in the amnesic patients. These patients with severe global amnesia were lacking a normal cortisol rise that takes place during early morning hours (Wolf et al, 2005).
During the first trimester of pregnancy, it is common, for up to 65 percent of females to experience vomiting and/or nausea. These symptoms are described as "morning sickness" (Flaxman & Sherman, 2000).
It is known that pregnancy of modern women means chronic
hyperventilation. Many of these women have even heavier breathing
during sleep in comparison with their usual daily chronic
hyperventilation. Hence, they often experience adrenal fatigue and high
morning cortisol and morning headache fatigue.
Conclusions. Most diseases appear and progress due to
heavy breathing during
early morning hours. Severely sick people are most likely to die during
the same time of the day (about 4-7 am). The real health of the person
can be only as good, as their morning CP measured immediately after
waking up. All previous tables and graphs do not reflect the full story
about the health state of the sick people since all those measurements
(minute ventilation, CP, etc.) were done during the daytime.
Causes of Heavy Breathing at Night
breathing during sleep
- Overeating or too late meals
- Poor quality of air and allergies
- Upper-chest breathing
- Sleeping on one's back
- Lack of physical exercise
- Lack of grounding to Earth
- Lack of essential nutrients and low blood cortisol levels
To solve the problem with morning hyperventilation is one of
the main goals of the Buteyko breathing method.
Note. These results (about heavy breathing and
critically low body oxygenation in the sick) also suggest that all our
previous considerations (Graphs and Tables about the prevalence of
hyperventilation in the sick, their oxygenation, etc.) underestimate
the real picture. The real respiratory parameters in the sick patients are worse
than those that have been measured by doctors, scientists, and
researchers during daytime studies and investigations.
Two main causes of heavy breathing
at night and millions of deaths during sleep worldwide every year are 1) sleeping
on one's back and 2) mouth breathing at night. There are simple and specific
methods or techniques to address these and other problems. The links to
these methods (how-to instructions) are provided right below here as your
