Dinghu Mountain is located in Zhaoqing City, Guangdong Province. It is known as the "Green Pearl of Lingnan" and is a famous nature reserve and tourist attraction in China. It has rich plant species and beautiful scenery, and is one of the four famous mountains in Guangdong. Its negative ion concentration is as high as 125,000/cm³. Such an environment has many positive effects on human health.

Benefits of negative ions to humans:

1. Enhance immunity: Negative ions can neutralize positive ions (such as free radicals) in the body, helping to enhance immune system function and improve the body's ability to resist disease.

2. Improve the respiratory system: Negative ions help reduce the symptoms of asthma and other respiratory diseases and promote respiratory health by improving gas exchange in the lungs.

3. Improve cardiovascular health: Negative ions help lower blood pressure, stabilize heart rhythm, and have a certain positive effect on preventing heart attacks and strokes.

4. Improve sleep quality: An environment rich in negative ions can help people relax their body and mind, thereby improving sleep quality and reducing insomnia.

5. Reduce stress and anxiety: Negative ions can increase serotonin (a neurotransmitter) level in the brain, thereby helping to relieve stress and anxiety and improve mood and mental state.

6. Promote metabolism: Negative ions can promote the activity of enzymes in the body, help strengthen the metabolic process and maintain physical health.

In an environment like Dinghu Mountain, people can return to nature and enjoy the tranquility and peace brought by nature. In addition to enjoying the beautiful scenery, you can also engage in various outdoor activities, such as hiking, mountain climbing, bird watching, etc., which can bring people closer to nature and feel the power of nature.

Due to the extremely high negative ion content in the air of Dinghu Mountain, people can inhale a large amount of negative ions when staying here or engaging in outdoor activities, which has significant benefits for health. In addition, the beautiful scenery here also helps reduce stress and improve people's mood, further promoting physical and mental health.

In short, Dinghu Mountain is an ideal leisure vacation and health resort destination, which not only provides people with the opportunity to get close to nature, but also brings many health benefits, especially thanks to the extremely high concentration of negative ions in the air.
