Internet Deception About Ideal Sleep Position
Why Sleeping on Your Back is Very Bad for Your Health
Surely, sleep is crucial for good health and each sleep parameter matters
for well-being and even the life of many people. What are the ideal sleeping
positions for better health? If you try to search the World Wide Web using
simple keywords like “best sleeping postures” or “correct sleeping
positions” or “perfect postures for sleep”, you will find out that over 80%
of popular websites advise to sleep on one’s back (called "supine sleep"). They
say that it is the ideal sleep position due to minimum stress for a human spine.
These internet resources are usually created by chiropractors, medical doctors,
nurses, and alignment specialists. They view the human body as a physical device
with angles, bones, curves, pressure, and tension. These professionals surely
have good intentions while providing this advice, but their oversimplified view
of the human organism has catastrophic effects
Professional medical research has found that sleeping on one’s back is the
most harmful sleeping posture for: - coughing attacks, - sleep apnea, -
back pain in pregnancy, - irregular or periodic breathing, - sleep paralysis
and terrifying hallucinations, - nocturnal asthma, - health of geriatric
inpatients, - asthma, - health of pregnant women, - asthma and allergies, -
pulmonary tuberculosis treated by thoracoplasty, - snoring, hypopneas and
apneas, - heart failure with sleep apnea, - chronic respiratory
insufficiency, - bruxism and clenching episodes, - stroke in elderly patients.
For references and abstracts of all these studies quoted, see the links below.
Furthermore, there are no professional medical publications or articles that
found positive aspects of sleeping on one’s back for any health problem. (As
I am going to argue below, supine sleep will gradually destroy even bones
and the spine in predisposed individuals.)
Is there any common mechanism since numerous studies revealed the same
adverse impact of supine sleep on very different health troubles? Authors of
several healthcare publications found the biggest reduction in the oxygenation
of the arterial blood for sleeping on one’s back in comparison with lateral
sleep (left side or right side) and prone sleep (sleeping on the stomach,
chest or belly) (Hjalmarsen & Hykkerud, 2008; Trakada et al, 2003; Szollosi
et al, 2006; Fast & Hertz, 1992). It is a common finding that reduced oxygen
content in the body is the critical factor that leads to the progress of many chronic diseases.
Furthermore, scientific publications have
clearly determined that the highest mortality rates and most pronounced acute
symptoms occur during the early morning hours (from about 4 to 7 am) for
diabetes, COPD, coronary spasms, sudden cardiac arrest and deaths, inflammatory
disorders, cerebral ischemia and stroke, epilepsy seizures, asthma and morning
sickness. Other healthcare articles devoted to circadian variations in different
physiological parameters in healthy subjects also determined that these early
morning hours are their worst times. For medical references and quotes see the
Why do all these problems occur?
If you observe the respiratory movements of people
sleeping on their backs, you can discover that they breathe more (e.g., faster
and deeper) in comparison with any other sleeping posture. For example, snoring is
a very common effect present for many people only during their supine sleep.
Why? This is because our rib cage and tummy are not limited and can freely move
in and out without any resistance. When we sleep on our sides or the stomach, breathing
movements are confined. Hence, sleeping on one’s back lowers the oxygenation of
cells due to overbreathing or hyperventilation (or breathing more than the tiny
medical norm: 10-12 breaths per minute and only 4-6 l/min at rest).
Breathing and ideal sleep positions
The reasons that overbreathing lowers the body's oxygen content are:
1. With tiny normal breathing, human arterial blood is approximately 98 per cent saturated with
oxygen. Hence, deep and big breathing cannot increase oxygenation of the
2. Most hyperventilators are chest breathers. Lower segments of the lungs do
not receive fresh air with superior oxygen content. Therefore, oxygenation
of the arterial blood becomes less.
3. Overbreathing signifies a CO2 deficiency in the blood and body cells, and that
immediately creates two effects: A) constriction of blood vessels (less blood and
oxygen is transported to all essential organs of the human body) and B)
the suppressed Bohr effect (less oxygen is
released in our tissues by red blood cells
since this oxygen release is controlled by carbon dioxide).
Both these effects
REDUCE oxygen and blood supply to cells promoting heart disease, asthma, stroke,
arthritis, cancer, diabetes, COPD, epilepsy, obesity and many other common
Moreover, numerous medical research articles found that hyperventilation
disrupts normal calcium metabolism and can lead to osteoporosis, brittle
bones and other related abnormalities. Hence, sleeping on one's back will
gradually destroy bones too. The effect will be even stronger, if a person
sleeps the whole night in a supine position.
Sleep is not a joke to take care about bones only. It is a fatal poison for the
chronically sick since millions of patients die every year because of the
impacts of sleep, where supine sleep is one of the leading factors of these
deaths. Therefore, the ideal or best sleeping postures must be selected based on
optimum personal respiratory parameters (easier and slower breathing) and
the greatest body-oxygen test test results. A particular stress-free breath-holding time check is the
easiest way to choose your best individual sleeping positions, as it is
explained in the first link above "Proper Sleep Postures".
