How to get taller at the age of 30

Getting old - this is how our body changes

In contrast to the growth phase, which is usually completed after two decades, the gradual "decay" of our body takes much longer. When the first signs of age appear cannot be clearly determined - too many influences play a role.

One thing is certain, however: the aging process is irreversible in many respects. This means that once degenerated areas of our body can no longer return to their original state on their own. A fountain of youth or the legendary philosopher's stone - which are supposed to ensure eternal youth - has not been found to this day.

Primary and secondary aging process

Two important factors are decisive for the aging of our organism and ultimately make our life finite:

  • Primary aging: Many parts of our body have a limited lifespan. Above all, various processes in our cells are responsible for the fact that at some point they can no longer carry out their tasks to the extent necessary. While the body systematically renews itself at a young age, this ability decreases with increasing age. This is therefore also called physiological aging.

  • Secondary aging: In addition to the natural aging process, there are also individual external influences. Various factors such as diseases, environmental toxins or our general way of life also affect our maximum life expectancy. The more stressful different things affect us, the shorter our life span becomes - depending on the individual constitution.

This shows how complex the aging process in our body is. Both the biological prerequisites due to genetic predisposition and external factors determine our age.

Everyone ages differently

The aging process is just as diverse in each and every one of us. Some face thinning hair and an increasingly higher forehead at an early age. Others, on the other hand, still enjoy thick hair growth in old age and you have to look in vain for even gray or even white hair with them.

The individual gene cocktail defines how strong our cells' ability to regenerate is. Some people are more resistant to external influences, while others are more often afflicted by diseases. In addition, it is also very different which areas of our body age faster than others.

However, a study with identical twins also confirmed the extent to which external circumstances affect the aging process. The study included pairs of twins in which one of the two smoked regularly while the other did not smoke at all.

As a result, the smoking twin showed clearly visible signs of age - more so than the non-smoking sibling. Signs of this were more pronounced wrinkles and more pronounced bags under the eyes and under the eyes. With our lifestyle - which also includes other factors such as a healthy diet, sufficient exercise and the avoidance of harmful environmental influences - we can influence our lifespan ourselves.

Do women get older than men?

There are statistical differences in life expectancy depending on gender. The external living conditions are more responsible for the differences. At the biological level, basically the same prerequisites exist for both sexes.

Signs of aging in our body

The aging process is noticeable in a wide variety of areas. Some of these are externally visible, such as changes in our skin or hair. Others, on the other hand, concern internal processes in our organism that can still be felt for ourselves. However, this often happens very slowly and only over time do we notice that our performance or mobility is restricted.

The aging of our sense organs

Presbyopia or hearing loss are typical complaints that can arise with increasing age - regardless of external influences. There are also differences in the eye:


Presbyopia - the age-related farsightedness - is caused by the gradual decline in the ability to accommodate. This means that the lens can no longer be focused sufficiently. This is by no means due to the slackening of the eye muscles, but rather to the fact that the lens loses its elasticity.

However, glasses are one of the most widespread correction options here and have become a fashion accessory in the process. While the frames used to be quite clunky due to the often thick glasses, everything is possible today thanks to the progress in production. Thanks to slim lenses, even with high diopters, there is a wide range of options - glasses have long since lost their character as a health aid. Adapted to the respective eyesight, they ensure that we can still see well up close, without restrictions, into old age.

Furthermore, the risk of losing sight due to various diseases increases with age. These include age-related macular degeneration as well as glaucoma (glaucoma) or cataracts (cataracts). Various treatments and surgeries can stop vision loss.


Our hearing ability also decreases with age. This becomes clearer for many from around the age of 50. The so-called age-related hearing loss (presbycusis) is largely due to external influences - for example, from noise pollution. Here too, hearing aids can be used to compensate for the loss of hearing. Depending on how severely the hearing ability is impaired, different models come into question. At the same time, these devices have now become so small due to technical progress that they can be worn relatively inconspicuously.

Further sense organs

The sense of taste and smell also decline with age, as the sensory cells on the tongue and nose become fewer. The influence of nicotine consumption or the intake of various medications also have a negative effect.

Changes in hormonal balance

Hormones play a central role in controlling many processes in our body, including aging. This is most evident in women during menopause. The two hormones estrogen and progestin are released less and ensure that the ability to reproduce is gradually ceased. This is associated with typical side effects such as sudden hot flashes or severe mood swings, which can sometimes be troublesome.

The end of menopause is known as menopause and it also marks the end of a woman's fertile period. On average, they are between 45 and 55 years old.

In men, however, menopause is usually less noticeable. The hormonal changes are less pronounced here and are much more gradual. This means that more severe complaints are rare. The word andropause is used as a counterpart in the male gender. Yet men are not affected by the complete loss of their fertility.

Further hormonal changes affect glucose tolerance for both sexes. This often results in an increased blood sugar level and the risk of developing diabetes increases.

Our skin also gradually loses the ability to produce vitamin D through exposure to the sun. This has a negative effect on bone density - a secondary disease is osteoporosis.

The skin as a reflection of our age

The skin is the largest visible indicator of our age anyway, even if no reliable statement can be made about our actual age. Because here, too, it applies that with some the skin looks young and fresh for a long time, while others are already strongly marked.

The slowed cell metabolism ensures that the elasticity of our skin decreases from around the age of 25. As by far the largest organ, it is exposed to external influences more than anyone else throughout its life. For this reason, we can also strongly influence the extent of visible skin aging ourselves.

Not only factors such as smoking or strong sunlight, stress can also accelerate the aging process. But UV light in particular is responsible for the formation of free radicals in the skin cells, some of which can be irreparably damaged as a result. In the worst case, skin cancer can result.

However, the aging of our skin is also genetically determined. The connective tissue loses its elasticity and stability because collagen and elastin, the necessary building blocks, are gradually missing. The consequences are poor moisture regulation and a decrease in fat production - wrinkles form and the top layer of skin becomes thinner, while the pores become larger.

With increased care, i.e. sufficient moisture and fat supply, e.g. through creams, the aging process can be reduced to a certain extent. In addition, the skin should always be protected from excessive UV radiation throughout life.

Changes in the cardiovascular system

The heart achieves true top performances in the course of our lives. Hundreds of liters of blood are pumped through our organism every day - with physical exertion the strain increases even further. There are differences between the sexes, because the female heart is on average smaller than the male and has to compensate for the missing volume with a stronger pump.

As part of the natural aging process, the heartbeat volume decreases as the years progress. This means that when the heart is challenged, it has to beat faster. In addition, it is increasingly difficult for our blood vessels to adapt to the changing blood pressure when pumping. When sitting or standing, in contrast to a horizontal body position, circulatory problems can arise.

Above all, our lifestyle and diet can lead to deposits and constrictions in the blood vessels, which makes blood circulation more difficult and stresses the heart. If atherosclerosis is advanced, there is a risk of a heart attack or stroke. High blood pressure (hypertension) is one of the most widespread diseases today and, together with obesity or diabetes, is the most common cause of atherosclerosis.

How resilient the cardiovascular system remains in old age, however, also depends on how much it is regularly challenged. Because it is precisely the performance of the heart that can be trained through sport, for example.

Changes in the musculoskeletal system

Our bones are supported by muscles, tendons and ligaments, all of which are exposed to great stress. Of course, this leaves its mark. Muscle mass decreases with age. Even with increased training, it becomes more difficult to build muscle. The basic skeletal muscles are also affected. The result is a decrease in our strength and a gradual decrease in our mobility.

Ligaments and tendons

Since these cannot be renewed, they wear out due to daily stress. In the event of injuries, there are only limited options for “repairing” them. So if there is damage, we usually have to live with restrictions on our mobility. Nevertheless, they naturally lose their elasticity.


Here it is the so-called osteoarthritis that causes creeping degeneration over the years. If these are subjected to above-average stress, for example through being overweight or regularly exercising heavy physical strain at work, inflammation or deformations can occur. The knee is most often affected here.

However, medicine can help with various methods to maintain mobility for as long as possible. On the one hand, an attempt is made to reduce the friction and thereby further wear, on the other hand, an artificial joint can be used if the cartilage and bones are severely worn.

Immune system as a mirror of vitality and performance

The state of our immune system changes again and again in the course of our lives - depending on our overall physical condition. The immune cells lose their capacity due to a decrease in special white blood cells, and their overall activity decreases.

In addition, from around the age of 30, the basal metabolic rate of our metabolism gradually decreases. As a result, other processes in our body run more slowly and our organism as a whole becomes more vulnerable. If the task of warding off diseases can no longer be fully carried out, the vitality of our entire body suffers.

The deterioration of the immune defense is influenced by other factors such as chronic illnesses, stress or other stressful living conditions. Here in particular, diet and physical fitness through sport and exercise play a decisive role.

Changes in the digestive processes

There are also noticeable changes in all internal organs that are involved in the digestive process. In the case of the kidneys, for example, the ability to filter pollutants from the urea decreases over time. This means that more of it remains in the body and can possibly damage the organism.

The fact that we have to urinate more often is also often perceived as uncomfortable. The muscles of the urinary bladder lose their elasticity and can no longer hold the fluid so easily. In addition, the capacity of the bladder decreases.

Many seniors feel less hungry or thirsty as they get older. If you don't take care to drink enough fluids and food yourself, you put additional strain on your body. In the worst case, it can lead to gradual dehydration, and the body is also lacking more and more nutrients in order to function properly.

Mental degeneration

As a typical illness that affects our mind, the first thing that comes to mind is dementia or Alzheimer's. The performance of our brain decreases, which is reflected in various effects. Thinking, working memory, language skills and motor skills can all be impaired.

Age dementia is initially noticeable in an increasing forgetfulness. Further symptoms are an impaired ability to concentrate, or a decrease in the speed of information processing.

The causes of the decline in intellectual abilities are changes in our brain, triggered by the destruction of nerve cells due to circulatory disorders (vascular dementia) or protein deposits (Alzheimer's dementia). In some cases this is also genetic and can be inherited.

Like other age-related complaints or illnesses, the restriction of our brain performance has a not inconsiderable influence on everyday life. With increasing dementia, many previously self-evident situations can no longer be mastered alone. In many cases, the elderly are then dependent on help.

A great way to prevent dementia is to challenge our minds for as long as possible. If you keep your memory busy, you ensure that connections between the cells continue to be made. The loss in the case of gradual destruction is then not so significant.


Aging shows itself in our body in the most diverse areas and we are sometimes confronted earlier, sometimes later with the resulting restrictions and complaints. The more vital each individual component remains, the fewer negative effects there are for the entire organism. With our way of life we ​​can make a major contribution to staying physically and mentally fit for as long as possible and to increasing our life expectancy. Because a significant part of the impairments in old age is caused by external influences.
