What should I do if I want to grow taller at 18?

At 18 years old, if you still wish to grow taller, you should first undergo an epiphyseal line assessment. If the epiphyseal lines have already closed, your height is likely fixed, and there are generally no effective methods to further increase it. However, if the epiphyseal lines remain open, there is still potential for growth. In such cases, you can promote height growth by appropriately consuming calcium-rich and protein-rich foods—such as eggs, milk, and shrimp—engaging in regular jumping exercises, and ensuring sufficient sleep to stimulate the secretion of growth hormone.
