The “two-legged” simply rests one leg on the other, wanting to be comfortable will be so harmful? People are animals that like to toss and turn and need to constantly change body posture to maintain muscle tension and adjust the relative position of the body to maintain a comfortable state. Crossed arms, jaws on the cheeks, stretched legs are all such actions. Why is it called “Erlang-leg”? One cultural explanation is that in many temples in Sichuan province where the god Erlang is worshipped, he sits in this position. Therefore, the action of resting one leg on the other leg is called “stilted legs”. Interestingly, there is always a part of life is difficult to comfortably and beautifully stilt legs. For example, many friends with thick and short lower limbs, it is very difficult to do this posture. From an anatomical point of view, the thighs need to be maintained by the thigh muscles, which are in charge of the contraction of the foramen ovale nerve. Therefore, if the foramen ovale nerve is damaged, you will not be able to stilt comfortably. In addition, abnormal contracture of the gluteal muscles can also cause the inability to stilt. Does stilting affect reproductive health? There is no evidence! The leg that is resting on top of the leg is relaxed and comfortable when stretched because there is no need to carry weight. There is no doubt that the weight-bearing leg below will be under increased pressure. In terms of physiological structure, this will make the knee joint and the nearby nerves and blood vessels are subject to some compression. In addition, because the legs are in a crossed position, the heat dissipation in the thighs and perineum will also be reduced. For men, stretched legs may briefly increase the temperature of the perineum and even bring discomfort. This is mainly due to the increased local pressure, which affects the blood flow in the area. Therefore, it is not recommended that long periods of tightly clamped stilts, which are indeed too invasive to the male “that space”. However, there are no clear findings on whether the above effects will affect male reproductive function. For women, stilting does not usually lead to perineal discomfort, and there are no clear studies suggesting that stilting causes an increased risk of gynecological disease. In other words, there are so many different types of gynecological diseases and so many different factors that we cannot attribute them solely to the action of stilting. Stretching your legs can cause high blood pressure? Not true! Hypertension and elevated blood pressure are two different things. To be precise, there are studies that show that stilting does cause a transient increase in blood pressure. This is especially strong for people who already have high blood pressure. However, a one-time increase in blood pressure is not diagnostic of hypertensive disorders. Why does stilting cause an increase in blood pressure? Because this action affects the return of venous blood from the feet and legs to the heart, and then the heart can only overcome this problem of reduced blood return by raising the blood pressure. When a person with hypertension stretches his legs, his systolic blood pressure increases by 6.7 mmHg and his diastolic blood pressure increases by 2.3 mmHg. The good thing is that when you don’t stretch your legs, this effect of increased blood pressure disappears. This is the reason why health care professionals usually ask patients to sit upright with their feet on the ground when taking their blood pressure. Can stilts aggravate varicose veins in the lower extremities? It’s true. People who already have varicose veins in their lower extremities, stretched legs will make the veins more strongly compressed locally, which will further aggravate the symptoms of varicose veins, thus making the calves numb and swollen, and even painful. Therefore, if you want to stilt your legs, the time should not be too long, such as three or five minutes after the leg change. And people who have varicose veins or edema in their lower limbs, it is better not to stilt. As a lifestyle habit, there is no obvious harm in stretched legs. Even if it will cause some health damage, mostly on top of the original disease, and is a long-term chronic process. What’s more, compared with poor office study sitting, long periods of sedentary, stilted legs can not be considered a bad body posture. Studies show that 30% of adults worldwide do not do exercise, mainly for long periods of sedentary, watching TV and other bad habits. These bad habits can cause damage to an individual’s health, most notably by increasing the risk of death. In other words, compared to excessive attention to such a pet peeve as leg stretches, we should pay more attention to sedentary.
