In medicine, negative oxygen ions are known as "vitamins in the air" and "longevity factors", which can effectively decompose and reduce harmful gases in the air, make people clear-headed, refreshed, enhance skin elasticity, alleviate aging, prevent and improve respiratory diseases and cardiovascular and cerebrovascular diseases, lower blood pressure, increase appetite, and regulate physiological functions of the body.
Extended data:
Function:
The researchers mainly studied the effects of small negative oxygen ion groups on human body through three ways of lung breathing:
First, it can accelerate the movement of respiratory epithelial cilia locally;
Second, after the body fluid enters the blood, it releases charges to act on cells and protein, thus oxidizing and inhibiting 5- hydroxytryptamine in the blood;
Third, reflex stimulates the conduction of receptors and nervous system, but it acts on the central nervous system and autonomic nervous system of the brain, and its charge enters cerebrospinal fluid through the blood-brain barrier until it affects nerve function. Experiments show that negative air ions can reduce the content of 5- hydroxytryptamine in blood and enhance the process of nerve inhibition.
It has sedative, hypnotic, and blood pressure lowering effects, which can speed up the frequency of brain waves, speed up the duration of motor sensation, slow down the erythrocyte sedimentation rate, reduce blood viscosity, increase plasma protein and erythrocyte hemoglobin, enhance the oxidation process of kidney, liver, brain and other tissues, and enhance the oxygen absorption and carbon dioxide excretion functions of the lungs.
