Most people stop growing taller after their early twenties because the growth plates in the bones usually close after puberty. After this stage, significant natural height increase is generally not possible. However, experts say factors like posture improvement, spinal alignment, fitness, and maintaining healthy bones can make a person appear taller and more confident.
Exercises, stretching, and proper nutrition support overall musculoskeletal health but do not permanently increase bone length after growth plates close. Conditions like Growth Hormone Deficiency may affect height development earlier in life and require medical evaluation and treatment.
