There are receptors throughout the respiratory tract, which are vagal afferent nerve endings distributed in the mucosal epithelium that, when subjected to mechanical or chemical stimuli, cause a defensive respiratory reflex to clear the irritant and avoid its entry into the alveoli. What can be done to prevent impaired respiratory reflex regulation? Let’s take a look at it: Blood pressure can reflexively affect respiration when there is a large change in blood pressure, and when blood pressure rises, respiration weakens and slows down; when blood pressure decreases, respiration strengthens and speeds up. The regulation of respiration by chemical factors is also a reflexive regulation of respiration, chemical factors are O2, CO2 and H+ in arterial blood or cerebrospinal fluid. The body regulates the levels of O2, CO2, and H+ in the blood through respiration, and changes in the levels of O2, CO2, and H+ in the arterial blood regulate respiration through chemoreceptors, thus forming a control loop that maintains the relative stability of these factors in the internal environment. Treatment needs to be related to the above listed etiology. Insomnia is a subjective definition that can consist of two main components: First, the individual feels that he or she has difficulty falling asleep, wakes up easily in the middle of the night, wakes up very early and cannot fall back to sleep, cannot get enough sleep no matter how much he or she sleeps, and has combined problems with poor sleep. Second, poor sleep leads to daytime dysfunction, such as easy fatigue, depression, poor mood, and even physical discomfort, such as palpitations, gastrointestinal discomfort, etc. Improve sleep environment a good air quality is very important, long stay in the city confined room, people will feel dizzy, when coming to the forest, seaside, waterfalls and other places, we will feel refreshed, this is the role of negative air ions. Negative air ions, also known as negative oxygen ions, refers to the excess electrons and negatively charged oxygen ions. It is the formation of oxygen molecules in the air combined with free electrons. Nature’s discharge (lightning) phenomenon, photoelectric effect, fountains, waterfalls, etc. can make the surrounding air ionization, the formation of negative oxygen ions. Negative oxygen ions in the medical community enjoy “vitamin oxygen”, “air vitamin”, “longevity”, “air vitamin “and other beautiful name. United Nations experts in the field of environmental protection pointed out that the standard for judging the quality of air is the content of negative air ions, negative air ions can improve the ecological, living environment, and thus strengthen the organism’s own immunity, negative oxygen ions in the small ions can capture floating micro-dust, so that they coalesce and settle, thereby purifying the air. When the concentration reaches 2000/cm3, the floating dust in the air will be reduced by more than 98%, and the smaller the diameter of the floating dust, the easier it is to be precipitated. So in the air environment with high concentration of negative oxygen ions, the micro-dust, bacteria, viruses, etc. below 1 micron in diameter are almost zero. So the air environment that is not harmful to human body is created, so it can be said that the amount of negative oxygen ions is one of the important criteria to measure whether the air is fresh or not.
