Height increase depends on three things:
1) Growth Plates
2) Genetics
3) Growth Hormone levels in the body
If the growth plates are open, then there is a good chance for height increase up to three to four inches but if the growth plates are closed, then it becomes difficult for height increase.
Genetics determines a person's height in most cases, but if proper nutrition is given to the child and proper exercises are done at a young age then the child can increase height and grow taller than the parents.
Growth hormone is very critical for height increase, if the growth hormone is less in the body, then even if the growth plates are open and even after following diet and exercises, the height will not grow.
Here are the top 6 ways to increase height:
1) Do proper height increase exercises, which include stretching exercises and cardio exercises.
2) Follow a well-balanced diet, rich in protein and calcium and less sugar and processed foods.
3) Sleep is very essential for the release of growth hormone, a minimum of seven hours of sleep is essential.
4) Take herbal supplements for height increase and avoid harmful synthetic supplements available in the market.
5) Avoid a sedentary lifestyle and follow an active lifestyle.
6) Do Surya namaskar daily as it is a very good exercise for height increase.
