[Deep breathing, the simplest longevity action] Modern people only take an average of 3.3 seconds to breathe at a time. The shallow and short way of breathing is not only easy to make people lack oxygen and feel tired in the brain, but also closely related to anxiety, stress, depression, and cardiovascular and cerebrovascular diseases. Zhi Xiuyi, director of the Lung Cancer Diagnosis and Treatment Center of Capital Medical University, recommends a simple breathing training method: inhale - stop (hold your breath for 10 to 20 seconds) - exhale, and the process is as even and smooth as possible. When breathing, let the amplitude of the lungs have a distance of more than two intercostals to ensure the elasticity of the lungs. Within 3 to 10 minutes of each control, do it two or three times a day and exercise lung capacity in situ.
