Hi Kanchan,

Hope you are fine. Unfortunately, there is very less possibility for you to increase your height by 2cm that too within 1 month since you're already 22. Generally at the age of 22, any individual is most likely to have reached their maximum growth as the growth plates close by this age.

However, there are plenty of ways a person can improve their posture to look taller.

• Do immense stretching exercises like hanging from bars, swimming, etc.
• Take daily sprints (fast running up to 75m - 100m)

Hope this helps and wish you the best of luck.
