I am not sure if this idea is even valid due to the curvature of each individual person head relative to the vertebrate. However maybe the easiest way to increase one’s height is to develop a more confident, upwards posture.
The three parts towards displaying confidence through body language in males is to…
- Breath in the stomach
- Pushing upwards the chest
- Lifting the Shoulders
It is basically the idea that having one’s chest pushed outwards means that the vertebrate will be more likely to be straighter.
What I am describing is what most people do when they are getting their height measured, which is to try to maximize the height measured.
Most people who stand have some curvature in all of the sections of the vertebrate, from the cervical to the thoracic to the lumbar area.
In general there is little that simple posture and stretching can change the lumber are of the back. Only rolfing or a chiropractor can have a chance of causing the vertebrate to be aligned striaghter.
The thoracic section is usually curved and that is also not easy to straighten out. The cervical region is the area which is the most flexible.
The human body is designed so that most people can only bend in the forward direction. Contortionist are the exception. What we want to focus on is to decrease the natural curvature of the vertebrate to something that is straighter. If the series of vertebrate bones are kept taut and aligned properly, there will be less height lost from curvature.
So there is basically one concept in this idea on possibly increasing ones height. It is to use the muscles in the torso to expand out to pull the upper body area up against the gravity, thus resulting in a slightly increased measured height. However I have wondered whether lifting the shoulders up, breathing in the stomach, and pushing out the chest would mean that the overall torso would move upwards or it just seems that way.
Something else to note
Most people are actually really bad at estimating height, except for people who are 2 inches taller or shorter than them. (Whatever most men may think of themselves at being better than average height guessers, most are very wrong)
What most people do to compare their height with someone else is to look to where where they eye level is compared to the other person. For most people, as long as the eye level height of themselves is higher than the other person, they automatically assume that they are taller. What is not known to most people is that the distance from the middle of their eye level to the top tip of their head is around 4-5 inches long.
This might explain why more dominant , alpha males always tilt their head up and look straight forward instead of lowering their head and look down on the ground.
The main point is that maybe from good strong, dominant body language where the shoulder, stomach, and chest are held in position that makes one look more dominant, it would appear to other people that one is taller.
If it actually works in using the body’s core abdominal muscles to temporarily hold up the upper torso higher to elevate one’s height is not known.
