Negative ions are called "air vitamins" in the medical community. Their main functions are as follows:
1. Effect on the nervous system. It can strengthen cerebral cortex function and mental activity, invigorate the spirit, 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. It affects the cardiovascular system. According to the observations of scholars, negative ions can significantly expand blood vessels, relieve arterial vasospasm, and achieve the purpose of lowering blood pressure. Negative ions are also very beneficial to improving heart function and improving myocardial nutrition, which is beneficial to the condition of patients with hypertension and cardiovascular and cerebrovascular diseases. recover.
3. It affects the blood system. Research has confirmed that negative ions can slow down blood coagulation and flow, prolong blood coagulation time, increase the oxygen content in blood, and facilitate blood oxygen transport, absorption and utilization.
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 people's lung capacity. Someone once tested that inhaling negative air ions in a glass mask for 30 minutes can increase the amount of oxygen absorbed by the lungs by 20%, and the amount of carbon dioxide emitted can increase by 14.5%. Therefore, negative ions can improve and increase lung function.
In addition, negative ions in the air also have sedative and hypnotic effects. If we inhale an appropriate amount of negative ions every day, it will be of great benefit 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 disease and prevent colds and respiratory diseases. Improve symptoms of cardiovascular and cerebrovascular diseases. Under the action of negative ions, the excitability of bones can be increased and the duration of exercise can be reduced, which helps athletes improve their performance, especially for some events that require rapid response, such as sprinting, swimming, etc.
