In view of how to maintain physical and mental health and have a healthy body, Lao Tzu put forward several answers.
The first is simple food, diet and health. Laozi said: "Nothing, nothing, tasteless." Do it with a leisurely attitude, do it with a leisurely attitude, and taste the taste of peace. Laozi advocates a simple diet. The real way to eat is not big fish and big meat and delicacies, but simple tea and light rice. Many facts of later generations have proved the benefits of vegetarianism to people, as well as the scientific and profound nature of Laozi's health preserving thought.
In concrete practice, Lao Tzu put forward "Hold your breath, as soft as a baby?" Slow breathing rhythm means slower metabolism and blood flow, less heart load and less energy consumption. For example, the life span of a tortoise is closely related to its breathing style. Turtles breathe very slowly, breathing on their bellies. This special way of breathing is also the reason why turtles can live a long life.
Laozi thinks that abdominal breathing is very beneficial to people's health, especially the natural massage effect of turtle breath on abdominal organs, which promotes their life activities and stimulates their life potential.
Lao Tzu also said, "Living in a good place is good for your heart." Living in a beautiful land, the heart is like a clear and deep water. The so-called "auspicious land" is what later generations call the land of geomantic omen. In fact, Feng Shui has a certain scientific basis and is closely related to geography, architecture, psychology and meteorology. The subtle influence of feng shui on people is very great, even decisive, so we must choose a good place for health preservation.
