Modern medical research shows that negative air ions have a wide range of biological functions. When they enter the human body with the air, they can improve the nervous system, make people refreshed and happy, raise the level of enkephalin and play a calming role. Air negative ions can also promote the synthesis of erythrocyte hemoglobin in blood, stimulate hematopoietic function and improve heart function; Lung is an important part of negative air ions, which can improve the tension of smooth muscle and improve the ventilation function of lung. At the same time, it also contributes to the cardiovascular system, which can reduce the diastolic blood pressure and systolic blood pressure of patients with primary and menopausal hypertension. Even strong people need to constantly absorb negative ions from the air to make their spirits more abundant.
At present, there are many diseases treated with negative ions. There are many negative ion rehabilitation hospitals and negative ion health parks in Japan, and many hospitals in China use negative ions to treat asthma and chronic bronchitis. When used in neonatal nursery, it can reduce bacteria and prevent neonatal infection.
