The role and efficacy of negative ions

Now many people know that there is a negative ion beauty method. Because negative ions are called vitamins of the air, negative ions have many effects on the human body. Moreover, negative ions have many benefits to the human body. They can have a particularly obvious impact on the human nervous system, cardiovascular system and blood system. So what are the effects and functions of negative ions?

Negative ions are called "air vitamins" in the medical field. Their main functions are:

1. Impact on the nervous system. It can strengthen the function of the cerebral cortex and brain activity, boost spirits, improve work efficiency, and improve sleep quality. Negative ions can also strengthen the oxidation process of brain tissue, allowing the brain tissue to obtain more oxygen.

2. Impact on the cardiovascular system. According to scholars' observations, negative ions have a significant effect of dilating blood vessels, which can relieve arterial vascular spasms and achieve the goal of lowering blood pressure. Negative ions are also very beneficial for improving heart function and myocardial nutrition, and are beneficial to the recovery of patients with hypertension and cardiovascular and cerebrovascular diseases.

3. Impact on the blood system. Studies have confirmed that negative ions can slow down the blood coagulation rate and prolong the coagulation time. They can also increase the oxygen content in the blood, which is beneficial to the transport, absorption and utilization of blood oxygen.

4. Negative ions have the most obvious impact on the respiratory system. This is because negative ions enter the human body through the respiratory tract, which can increase human lung capacity. Someone once conducted an experiment and found that inhaling negative air ions through a glass mask for 30 minutes can increase the amount of oxygen absorbed by the lungs by 20%, and the amount of carbon dioxide discharged can increase by 14.5%. Therefore, negative ions can improve and increase lung function.

In addition, negative air ions also have a calming and hypnotic effect. If we inhale an appropriate amount of negative ions every day and persist in doing so, it will be beneficial to our health: it will make people energetic, eliminate fatigue and burnout, and improve work efficiency. Improve sleep and eliminate neurasthenia. Reduce the incidence of diseases and prevent colds and respiratory diseases. Improve the symptoms of cardiovascular and cerebrovascular diseases. Under the action of negative ions, the excitability of bones can be increased and the exercise time can be reduced, which helps athletes improve their performance, especially in some events that require quick response, such as sprinting and swimming.
