Bone marrow is found in the bone marrow cavity of the body and is the body’s blood-forming organ. The regenerative function of bone marrow is stimulated mainly by adjusting diet, strengthening exercise and promoting sleep. Since iron, high quality protein and vitamins are needed for the synthesis of human blood cells during hematopoiesis, it is important to pay attention to eating more iron-rich foods such as animal blood, liver, purple cabbage, dates, shiitake mushrooms and black fungus. Eat more milk, eggs, fish, shrimp, poultry, mutton, beef, lean meat, soy products, dairy products and other foods rich in high quality protein. Eat more fresh vegetables and fruits to ensure balanced nutrition. Bone marrow growth is more vigorous at night when you sleep, so pay attention to regular life and ensure sufficient sleep to help the growth of bone marrow. You can do more jumping and stretching as well as suspension exercises to help stimulate the regeneration of bone marrow.
