Are negative ions harmful to the human body?

Negative ions are charged oxygen ions. They are used quite frequently in our lives and are of great help to our bodies and lives. They generally have the effects of calming, helping sleep, relieving cough, diuresis and increasing appetite. In medicine, negative ions can also be used to treat diseases. They have many positive meanings for our lives and bodies. Let's take a look at whether negative ions are harmful to the human body.

The impact of negative ions on the human body:

According to expert observations and research, the main effects are as follows: it affects the nervous system, can strengthen the function of the cerebral cortex and mental 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. The 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. It affects the blood system.

Studies have confirmed that negative ions can slow down blood flow, prolong clotting time, increase the oxygen content in the blood, and facilitate blood oxygen transport, absorption and utilization. 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 2%, and the amount of carbon dioxide discharged by 14.5%. Therefore, negative ions can improve and increase lung function. Since negative ions are very beneficial to human health, in order to change the problem of negative ion reduction when using air conditioners, air conditioner developers have developed negative ion generators so that people can absorb "air vitamins" to their heart's content while sitting at home.

Through the above introduction, we know that negative ions are not harmful to the human body. In our daily life, we often come into contact with negative ions and use them frequently. It is good for our life and body. Therefore, we must pay attention to the correct use of negative ions in normal times to play the best role.
