In daily work, there are often some "unexpected gains" feedback: I originally received hyperbaric oxygen therapy for other diseases, but I was pleasantly surprised to find that the symptoms of insomnia have been significantly improved. Hyperbaric oxygen therapy is green and efficient. It can not only increase sleep time and improve sleep quality, but also regulate sleep disorders and reduce drug dependence. Insomniacs have received rave reviews after using it! One treatment with hyperbaric oxygen can restore your health.

About one-third of people in sub-health state suffer from sleep problems for a long time. Hypoxia is closely related to sub-health, and oxygen supplementation is an effective means to improve sub-health. The way of oxygen inhalation can be selected according to different states of sub-health.

Sufficient sleep, balanced diet and proper exercise are the three health standards recognized internationally. One-third of a person's life is spent in sleep. As a necessary process of life, sleep is an important part of the body's recovery, integration and memory consolidation, and an indispensable part of health.

World Sleep Day

In order to arouse the attention of the whole people on the importance of sleep and the quality of sleep, the Global Sleep and Health Program sponsored by the International Mental Health and Neuroscience Foundation launched a global activity in 2001-designating March 21 every year as the "World Sleep Day"--World Sleep Day.


In 2003, the China Sleep Research Association officially introduced "World Sleep Day" into China.

Chinese themes over the years

  • 2012: "Focus on sleep quality and sleep an extra hour"

  • 2013: "Natural deep sleep, sleep an extra hour"

  • 2014: "Sleep healthy, travel safely"

  • 2015: "Healthy Sleep, Get an Extra Day of Sleep"

  • 2017: "Healthy sleep, stay away from chronic diseases"

  • 2018: "Regular work and rest, healthy sleep"

  • 2019: "Healthy sleep, intelligence and brain protection"

  • 2020: "5G sleep, dream back home"

  • 2021: "Sleep healthy, travel safely"

  • 2022: "Sleep well, stay healthy"

This year's theme is: "Good Sleep, the Source of Health".

Survey on sleep status in China

The data in the "Investigation Report on the Current Situation of Sleep Diagnosis and Treatment in China" shows that 50% of netizens admit to having sleep problems, and high work pressure is the "culprit" that affects sleep quality. Although the average daily sleep duration of Internet users in China exceeds 7 hours, 56% of users still believe that they have sleep problems, including excessive dreams, continuous light sleep, and dizziness when waking up in the morning.

Sleep and sub-health

Sleep disturbance is a manifestation of sub-health in the central nervous system. The epidemiological study on the sleep state of sub-healthy people by the China Academy of Traditional Chinese Medicine pointed out that about one-third of the people in the sub-healthy state suffer from long-term sleep problems, lack of energy during the day, and sleep badly at night.

What is sub-health?


The World Health Organization defines sub-health as some functional changes without organic lesions. It is a transition stage between human health and disease. Although there are no organic diseases physically and psychologically, there are many uncomfortable symptoms and psychological experiences subjectively. Also known as "the third state of the body", "grey state".

Sub-health is between health and disease, and it is a state of low physiological function.


What are the manifestations of sub-health?

The symptoms of sub-health can be found in various systems of the body, but they are concentrated in the central nervous system with the largest oxygen consumption and the least oxygen reserve, such as: inattention, memory loss, headache, dizziness, insomnia, sleepiness, work ability decline, fatigue, etc.

If hypoxia cannot be corrected in time, other system discomforts will gradually appear, such as:

  • Respiratory system: Chest tightness, shortness of breath, easy to catch a cold

  • Circulatory system: palpitations, precordial depression, blood pressure fluctuations

  • Digestive: decreased appetite, diarrhea or constipation, feeling full

  • Motor system: fatigue, muscle soreness, bone and joint pain, numbness or chills in hands and feet

  • Immune system: prone to allergies, repeated colds

  • Endocrine and others: upset, menstrual disorders, night sweats, dry skin, dull complexion, vision loss, tinnitus.

What is the relationship between hypoxia and sub-health?

When the body is in a state of hypoxia, the energy (ATP) production will be deficient, which will cause the body to use ATP to complete normal physiological activities, resulting in a series of low or disordered physiological functions. And this disorder is the physiological state of sub-health.

Experimental research found that:

  • Hypoxia reduces the synthesis of ATP in rats, and the acid-base metabolism of cells, calcium channels of cells, and release of lysosomes are abnormal;

  • Hypoxia increases the blood viscosity of sub-healthy people, which will directly affect the blood flow velocity and affect the ability of hemoglobin to transport oxygen.

When hypoxia persists, hypoxia-inducible factors increase. Hypoxia-inducible factors are very sensitive to hypoxia and participate in the regulation of many hypoxic responses, which can cause cell membrane damage, decreased cell viability, and even nuclear pyknosis, shedding, and apoptosis.

How to replenish oxygen for sub-health?

Oxygen is the source of body metabolism, and hypoxia is one of the important causes of sub-health. Oxygen supplementation should obviously be an effective means to improve sub-health. The way of oxygen inhalation can be selected according to different states of sub-health.

Early stage of sub-health

Mild fatigue, sometimes insomnia, less enthusiasm and enthusiasm for work, loss of appetite, etc.

It is recommended that you pay more attention to your physical condition, and pay attention to whether there is hypoxia in the environment. According to the weather conditions, you should often open windows to ventilate, pay attention to physical exercise, and travel to places with good air in the suburbs, so that you can recover from the sub-health stage and stay away from the sub-health state. .

Early stage of sub-health

Inattention, dreaminess, insomnia or drowsiness, decreased ability to work, easy to catch a cold, diarrhea or constipation, full stomach, fatigue, blood pressure fluctuations, bone and joint pain, upset and other symptoms.

First of all, you should go to the hospital for relevant examinations to exclude organic diseases, and at the same time change your usual incorrect lifestyle and working methods;

Then try to ensure that you inhale oxygen 1-2 times a day, half an hour each time, and generally choose the noon break and after dinner. The method of oxygen inhalation is nasal catheter or face mask, oxygen bag or oxygen generator.

Sub-health state

The above-mentioned symptoms continue to appear, and often have headache, dizziness, chest tightness, breathlessness, palpitations, precordial depression, menstrual disorders, night sweats, dry skin, dull complexion, etc. There is no organic disease in the hospital examination, and oxygen therapy can be chosen. Including atmospheric oxygen therapy and hyperbaric oxygen therapy.

Normobaric oxygen therapy can refer to the early treatment of sub-health and the frequency can be appropriately increased according to the situation;

Hyperbaric oxygen therapy machine once a day, 2 hours each time, 10 consecutive treatments as a course of treatment. Practice has proved that hyperbaric oxygen is one of the ideal measures to treat sub-health. Usually, symptoms can be relieved after 1 to 2 courses of treatment, and intermittent oxygen therapy can be adopted for a period of time after that.

Hyperbaric oxygen and sub-health

What is hyperbaric oxygen therapy?

Hyperbaric oxygen therapy is the treatment of certain diseases by patients inhaling pure oxygen in a hyperbaric oxygen chamber under pressure (over one atmosphere). Hyperbaric oxygen has a unique therapeutic effect on some acute and chronic ischemic hypoxic diseases and secondary diseases caused by hypoxia.

At present, hyperbaric oxygen treatment of diseases involves various clinical disciplines, especially in the treatment of tinnitus and deafness, craniocerebral injury, cerebrovascular disease, anaerobic infection, carbon monoxide and other harmful gas poisoning, decompression sickness, air embolism and other diseases.

Why is hyperbaric oxygen better than normal pressure oxygen in treating sub-health?

  • Different treatment pressure and oxygen inhalation concentration: The mechanism of hyperbaric oxygen therapy and normal pressure oxygen is essentially different, which cannot be compared and replaced by ordinary oxygen inhalation.

  • Blood oxygen partial pressure is different: when pure oxygen is inhaled at normal pressure, the alveolar partial pressure of oxygen can reach up to 650mmHg, while the alveolar partial pressure of oxygen can reach 1433mmHg under conventional hyperbaric oxygen therapy.

  • The speed and distance of oxygen diffusion are different: under normal circumstances, the effective half-length of the diffusion distance of human gray matter capillaries is about 30 μm, but under hyperbaric oxygen, the effective half-length of the diffusion distance can reach about 100 μm.

  • The dissolved oxygen content is different: the physical dissolved oxygen increases under hyperbaric oxygen, up to 4.2 ml, which is about 14 times higher than that under normal pressure.

  • Oxygen reserves are different: under normal pressure, the average oxygen storage per kilogram of tissue is 13 milliliters, while inhaling pure oxygen under 3 atmospheres, the average oxygen storage capacity per kilogram of tissue can reach 52 milliliters.

  • Hyperbaric oxygen therapy also has a regulatory effect on the immune system and can mobilize the body's self-regulating potential.

Poor sleep quality is a common symptom of sub-healthy people. Reasonable use of hyperbaric oxygen therapy to supplement oxygen and break the vicious cycle of insomnia → hypoxia → insomnia will effectively promote the recovery of sub-health.
