Human height is an active field of research by different disciplines because it is determined by the combination of genetic and environmental factors. It is a quantitative or metric property, ie a property measured quantitatively, controlled by multiple genes and environmental factors. According to the researches, the average length of adult males is 176 centimeters and the average length of females is 163 centimeters. In addition, height varies from country to country depending on genetics and nutrition. In a study, the world's longest men were Dutch and Latvian women, and the average length of Dutch men was 1.83 centimeters, while the average height of Latvian women was found to be 1.70 centimeters. In addition, the world's shortest men are East Timor and the shortest women are Guatemalan. East Timor men are 160 centimeters tall, while Guatemalan women are less than 150 centimeters tall. These data are average numbers, and many people may go above or below the average height line. For the most part, height alone does not cause any specific health problems. However, longer and shorter people are at greater risk for certain health conditions.
Ovarian, Prostate and Other Cancers
Naturally, if a person is shorter than average, the risk of various cancers may be lower. Research has shown that tall women are more likely to develop both ovarian and breast cancer. Moreover, the risk of breast cancer is relatively low and the approximate risk rate increases by 1.2% per 10 cm. Tall women are slightly more susceptible to ovarian cancer, and this risk increases by about 2.1% every 10 cm. Various cancers, including colorectal cancer, skin cancer, kidney cancer, and leukemia, have a high risk of cancer for tall women.
Tall men face certain cancer risks, for example, prostate cancer risks increase by about 1% every 10 cm. However, this risk carries all types of cancer in men that are not related to smoking. As a matter of fact, all cancer types that are not directly affected by smoking are at a risk of approximately 0.5% higher at every 15 cm height. According to one theory, taller people have a higher risk of cancer. This is because people have more cells in their bodies. Because cancer is due to cell growth or irregular proliferation, more cells put people at greater risk.
Leg Length and Diabetes
Shorter people who are below average are at greater risk of diabetes. According to some studies, it may depend on general body shapes. In general, people with a larger belly are at greater risk of diabetes. However, longer-legged people may have slightly larger bellies than short-legged people without additional risk of diabetes. In a study of approximately 460 patients at risk for obesity, high blood pressure and type-2 diabetes, those with short legs were found to be less susceptible to insulin. Researchers have suggested that this may be due to malnutrition in childhood. Similar studies in China and Brazil have also confirmed the relationship between shorter legs and higher risk of diabetes.
Coronary Heart Disease
Shorter people have a higher risk of heart disease and heart attack, but this dis is not a factor. Roughly 180 genes contribute to shorter lengths, and some of these genes put the person at risk for heart problems. The shorter a person is, the higher the risk of heart disease. For every 6 cm shorter than the average, the risk increases by 14%. If it applies to this person, he does not need to worry. Much can be done to increase the chances of a healthy lifestyle. Not smoking, maintaining weight and blood pressure, preventing bad cholesterol (LDL), exercising regularly and doing what is necessary to keep the heart healthy.
Risk of Stroke
A person may seem to be protected from the risks of paralysis. When the blood flow in the brain suddenly stops, a stroke occurs, killing the brain cells. Depending on which brain cells are damaged, stroke can have various effects. The person at risk of stroke may have difficulty raising one arm, smiling on both sides of the mouth, or speaking consistently. Strokes can be small or large, and large ones can cause more severe stroke or death. A study followed more than 7,000 men and divided the men into four groups according to their height. As a result of the study, it was seen that the men in the longest group decreased the risk of stroke more than 50% compared to the shortest group. A similar study of 10,000 men found that the risk of paralysis of a man at a height of 5 cm was reduced by 13%. Other studies by both men and women in Japan and other countries have yielded similar results.
Risk of Blood Clots
A great health advantage for short people. If the person is taller, the risk of blood clotting in the vessels increases and this risk is usually experienced in the legs. The medical term for this is venous thromboembolism or VTE. It almost always affects one leg and can cause swelling, pain, redness and warmth in the VTE. It can be fatal when the worst blood clot pops and prevents blood flow to the lungs. In this case, chest pain, dizziness, rapid heart rate, breathing and sudden shortness of breath are experienced. Each year, more than half a million people are affected by VTE, and 60,000 to 100,000 of them are dead. As the global population continues to grow taller, events in this situation increase. The reason why taller individuals are more susceptible to blood clots has not been fully established, but experts have provided possible explanations. There is an opportunity for more clotting, as the blood circulates in the long legs further away. In addition, gravity itself can facilitate clotting in tall people.
In the case of different forms of dementia, including Alzheimer's disease, shorter people are at greater risk. Research has shown that both men and women have a higher risk of dementia, vascular dementia, and Alzheimer's. Some of these studies point out the main reasons for shortness. Fewer people are more likely to experience malnutrition that may suppress growth during childhood and may also make dementia even more likely. Another theory is that growth hormones protect against dementia in an unknown way, because other studies have shown that people with low growth hormone are more likely to develop these brain disorders.
How long a woman carries her unborn baby contributes. Women who are 155 cm or less give birth much longer than women who are 172 cm taller. The length of a pregnant mother can also help in predicting difficult births. As a result of the research, it was found that women who are first mothers who are shorter than 147 cm and 147 cm are more likely to deliver their babies by cesarean section. Shorter women also tend to have smaller babies. A study also found that a father's neck had no effect on the full duration of the baby.
Linked to Baldness Genes
Baldness is a very common problem affecting half of all men until the age of 50 years. According to a study investigating genes responsible for male pattern baldness, if the person is short, it is likely to become bald. According to researchers, at least 63 gene changes play a role in baldness, and some of these genes contribute to a shorter dimension.
There is a special genetic mutation that allows certain mice, flies, and even some worms to live longer. It is generally referred to as the Methuselah gene, which is named after the Bible character who lived until the age of 969. For mice, this gene has been shown to increase lifespan by up to 40%. Scientists have known the Methuselah gene for a long time, but have recently described it in humans. Researchers have discovered that people living until the age of 95 are more likely to carry this gene. This power plant gene makes the body less susceptible to a particular growth hormone, which helps explain why people with the Methuselah gene tend to be shorter than average. Some people are short for different reasons, including malnutrition. Some people may have a long life for different reasons, including income level and lifestyle. However, if the person is at least shorter than average, there is a possibility that they will carry genes for a longer life.
When working hard at an intense temperature or staying too long, being short can give an advantage. Shorter people can cool their body more efficiently than taller people. The more skin in the body, the larger the body mass. The larger the body mass, the more body temperature is formed. The skin is also the position where sweat collects body temperature before evaporating. Thus, it shows how much the skin can be heated and also where it cools. Unfortunately for people with more skin, the body cannot cool as efficiently as it warms. So the more the skin, the more heat it collects. Although this is a great advantage for people who are shorter in warmer climates, longer and overweight people have some advantages in cold. Because the larger the body, the faster it warms up and holds more heat.
In addition to potentially longer life and cancer, another advantage of being short is the low center of gravity. Shorter individuals are more likely to fall and the risk of injury is lower. Simply put, it is less dangerous for short people to fall down because they are closer to the ground. According to a study, women who are taller than 172 centimeters are more than twice as likely to have hip fractures during falls compared to short women below 1.57 centimeters. If a person is both a long and old adult, special precautions should be taken to prevent falls. These measures include observing prescription glasses, paying attention to drugs that cause dizziness, possibly going to the physiotherapist for special balance and strength exercises.
If a person has a lung problem, if a transplant is required and is on the waiting list, a short be a disadvantage. One study examined records of more than 13,000 adults waiting for lung transplants in the United States. In this study, it was found that people smaller than 1.60 cm waited for their lungs 35% longer than those who were taller. The probability of respiratory failure while waiting for the lungs is approximately 40% and mortality or lung extraction rates are higher than 60%. This problem affects women more because women are shorter than men.
Low Back Pain
Length may hurt the back. A study of 13,000 men and women found that being above average was significantly associated with higher back pain and a history of low back pain. On the contrary, this also applies to shorter people. Another great study of women has found that height can help predict future low back pain problems.
Risk of Glaucoma
Being tall helps to prevent glaucoma. Glaucoma, the second leading cause of visual impairment in the world, results from the accumulation of pressure in the eyes. Many studies confirm that people have different shapes depending on the size of their eyes. Other studies have shown that high cerebrospinal fluid pressure is associated with the risk of low angle glaucoma, the most common type of glaucoma. Tall people are more likely to have cerebrospinal fluid pressure. In addition, their eyes appear to be better adapted to eye pressure leading to angle-closure glaucoma, which can lead to sudden blindness and is generally considered more dangerous. Therefore, in both cases, taller people are believed to reduce the risk of glaucoma.
Even though the risks are reduced, taller people can still develop glaucoma. Regardless of height, the Glaucoma Research Foundation recommends regular eye examinations to prevent this debilitating disorder. Those under 40 should have their eyes checked every two to four years. This increases frequently if men and women are encouraged to have an eye examination every six months a year.
