Hello,
Thanks for posting your query.
Height under natural conditions increases due to increase in length of long bones in the arms and legs. Long bones have epiphysial plates located towards the end of the bones, which are cartilaginous tissue. After a particular age, this cartilaginous tissue gets converted to solid bone tissue and the height seizes to grow.
Height in males can increase up to the age of 19 years usually or a few years later if puberty is delayed . However its rare to see natural increase in height after 25 years 1.Simple stretching exercises can be beneficial in increasing height.
2.There have been several claims which suggest that use of Human Growth Hormone can also aid in increasing the height, but it's been linked with a host of detrimental effects on the overall health of an individual. Also the treatment requires a thorough evaluation and prescription by a endocrinologist .
3.Healthy diet also plays a vital role in improving height.
