My age is 19 years 8 months, my height is 5 feet 6 inches only. are there any tips to increase my height?

Height: Nope. It is now time to accept yourself as you are.

Be yourself: At your age, further vertical growth is unlikely. What you want to do instead is trim and develop your body -- which is at its prime. A muscular, lean man of any height looks far better than most of his peers. A shorter man is less threatening and may be preferred as a friend.
