This triangle is not the old Thai-Myanmar Golden Triangle, is long in the men’s body of some triangular area, if not protected these areas, will give you a lot of trouble, and even life-threatening, some are known as the “Dangerous Triangle”. 1, the danger triangle location: this triangle area by the root of the nose and both sides of the mouth line. There are 6 veins in the head and face that can lead to the intracranial veins, which have branches and communicate with each other, forming a dense vascular network. Dangerous formation: The facial veins are the only veins that do not have valves, and the venous blood carries the waste products in a continuous flow to the “waste disposal station”. However, due to the special structure of the facial veins, the blood will not only flow normally down into the jugular vein, but also up into the skull, leading to intracranial infections that can cause death. Safety warning: boils and pimples in the Dangerous Triangle, do not use your hands to squeeze, and to maintain hygiene, if necessary, go to the hospital to ask the doctor to deal with. 2, occipital triangle Location: The occipital triangle refers to the range under the occipital bone and including the first and second cervical vertebrae at the back of the neck. Here are the most complex joints in the human body. The left and right rotation of the head, head nodding, head shaking movements are mainly completed by these joints. Normal cervical vertebrae are slightly convex forward, nerves, arteries in the middle of the passage, such a curvature is easy to increase the elasticity of the cervical vertebrae, so that the head vibration to slow down. Dangerous formation: If you keep a bad posture for a long time, the cervical anterior convexity will gradually become straight, or turn into posterior convexity, it will compress the normal work of the nerves, blood vessels, not only easy to trigger migraine, stroke and other diseases, but also lead to cervical angina pectoris. When riding in a car, climbing high and other activities, pay attention to protect the pillow triangle to avoid danger. Safety warning: avoid sleeping on a high pillow; avoid prolonged forward bending of the head; avoid cold neck; avoid trauma. 3, the bladder triangle location: this area consists of two ureteral orifices and the urethral orifice of the three line. The place is the place to store the residual urine in the body. Dangerous formation: the mucous membrane at the bladder triangle is only a very thin layer of tissue, and the submucosal tissue lacks abundant blood vessels. As a result, the blood supply is insufficient and the ability to protect itself is relatively poor. Most of the lesions in the bladder, such as cystitis and bladder tuberculosis, occur here. In addition, although urine is generally sterile, it is prone to harbor bacteria. If you often hold your urine, especially if you have prostate hyperplasia, it will lead to a weakened bladder contraction, and the urine will not be able to empty completely in the bladder, contributing to the generation of bacteria and inflammation. Safety Alert: Drink plenty of plain water, at least 1,000 to 2,000 milliliters a day; and pay attention to the regular emptying of the bladder, do not hold urine for a long time, to avoid bacterial growth; to keep the urethral orifice clean and dry; to stop smoking and limit alcohol, and eat less spicy and stimulating food; to avoid urinary tract infections. 4, the reproductive triangle location: located in the pubic bone and perineum composed of triangular area, is the male reproductive system, urinary system, gonads location. Sexual well-being and succession depend on this. Risks: Trauma (broken penis, torn foreskin, external injuries, etc.), infections (sexually transmitted diseases, epididymitis, seminal vesicle adenitis, prostatitis, etc.), developmental anomalies (prepuce, cryptorchidism, absent testicles, small testicles, etc.), and masturbation and overindulgence are the common causes of problems in the genital triangle. Safety warning: keep clean and dry, avoid unclean sex, avoid masturbation, moderate regular sex, avoid trauma. 5, shoulder triangle Location: shoulder triangle is equivalent to the location of the upper arm shoulder joint deltoid muscle. This area is thick, the deltoid muscle from the front, outside, after three bread around the shoulder joint, the axillary nerve is distributed in which dominates the contraction and diastole of the deltoid muscle. Other joints in the body can only do two movements of flexion and extension, while the shoulder joint, due to its special ball and socket structure, can do five-direction movements. Dangerous formation: Due to the loose structure of the shoulder joint, if the movement is not proper, it is easy to injure the soft tissues of the shoulder due to instantaneous muscle strain; in addition, due to a variety of movements of the upper body will often use the shoulder joint, the soft tissues around the joint will be friction and extrusion, and it is easy to occur chronic strain or inflammation of the soft tissues. Safety Alert: Warm up sufficiently before exercise, so that the muscles and ligaments are fully stretched; the amount of exercise should be moderate, and all joints should be kept slightly bent in the exercise to avoid excessive movement and to avoid the resistance of the confrontation to injure the joints.
