It is believed that a person's height increases from birth to the age of 18 to 20 years. After this, his body height remains the same. In such a situation, the question arises that if there is no change in the height of a person's body even after 20 years, then why does his height start looking short as he grows older. In today's article, let us answer questions related to this.
When does body height start decreasing?
Live Science reports that when a person's age is between 40 and 50, bones stop forming in the body. Apart from this, the density of bones also starts decreasing at this age. Gradually, when the length and width of the bones start decreasing, the human body starts bending.
A report published in the American Journal of Epidemiology in 1999 claimed that between the ages of 30 and 70, men lose 1.2 inches in height and women lose about 2 inches. For this research, 2084 people were studied.
Spinal cord can also be a reason
The human spine is made up of 24 bones and the intervertebral discs located between them. These discs act like a cushion, whose job is to reduce vibrations. When you are young, these discs are fluid-filled and flexible.
They help maintain a person's height, but as people age, the amount of fluid in these discs decreases. This causes the spinal cord to lose length. Although this process is very slow, it continues and with age, its effect starts showing on a person's height.
Apart from the spine, a decrease in bone density also contributes to a decrease in body height with increasing age. In fact, bone density starts to decrease with age. Especially in women, this process accelerates after menopause, when estrogen hormone levels start to decrease. Due to the decrease in bone density, their structure starts to weaken, due to which they start to shrink and this leads to a decrease in height.
