no1: facial triangle prone to acne
danger zone: this triangle area is composed of the connecting line between the root of the nose and the corners of the mouth on both sides. There are 6 veins in the head and face that can lead to the intracranial. They have branches and communicate with each other to form a dense vascular network. This area is rich in blood vessels, sufficient nutrient supply, and timely removal of waste and toxins, so the facial skin is the most sensitive and active, and the problems of the whole body are easy to be concentrated here.
dangerous formation : facial vein is the only vein without venous valve, and venous blood flows continuously with waste & ldquo; Waste disposal station & rdquo;. However, due to the special structure of facial veins, blood will not only flow down to the cervical veins, but also flow up to the intracranial.
safety warning: if you have acne on your face, don’t squeeze it with your hands, otherwise the bacteria and dust on the skin around your hands or acne can easily enter the blood and flow around the venous network, which is most likely to cause organ infections such as eyes and nose, and even intracranial infection in severe cases.
no2: occipital triangle causing headache
danger zone : occipital triangle refers to the range under the occipital bone, including the first cervical vertebra and the second cervical vertebra behind the neck. Here are the most complex joints of the human body: occipital – first cervical – second cervical joints. The left-right rotation, nodding and shaking of the head mainly depend on these joints. The normal cervical spine is slightly convex forward, and the nerve artery passes through the middle. Such radian can easily increase the elasticity of the cervical spine and slow down the head vibration.
risk formation : if you keep bad posture for a long time, the lordosis of the neck will gradually straighten or turn into kyphosis, which will compress the normal working nerves and blood vessels, which will not only easily lead to migraine, stroke and other diseases, but also lead to cervical angina pectoris.
safety warning: avoid high pillow sleep. The high pillow makes the head bend forward and increases the pressure on the cervical spine, which is easy to accelerate the disease of the cervical spine; The neck and shoulders should be kept warm. The cold wind is most likely to hurt the muscles and bones. If the neck is blown by cold wind in the air-conditioned environment for a long time, it is easy to have rigidity and pain; In addition, we should always correct the posture of head, neck, shoulder and back, and don’t often tilt our head and shrug our shoulders; After maintaining the same posture for 1 hour, pay attention to relax the shoulder and neck muscles, and do some forward flexion, backward extension and rotation of head and upper limbs, so as to enhance the ability of neck and shoulder muscles to deal with sudden changes.
no3: easily injured shoulder triangle
danger zone : shoulder triangle is equivalent to the position of deltoid muscle of upper arm joint. The muscles in this area are thick, the deltoid muscles wrap around the shoulder joint from the front, outside and back, and the axillary nerve is distributed in it, controlling the contraction and relaxation of the deltoid muscle. Other joints of the whole body can only do flexion and extension, while the shoulder joint can do actions in five directions due to its special ball and socket structure.
risk formation: because the shoulder joint structure is relatively loose, if you do not exercise properly, it is easy to damage the shoulder soft tissue due to instantaneous muscle strain; In addition, because the shoulder joint is often used in various movements of the upper body, the soft tissue around the joint will be rubbed and squeezed, prone to chronic strain or soft tissue inflammation.
safety warning: fully warm up before exercise to fully stretch muscles and ligaments; The amount of exercise should be moderate. During the exercise, each joint should keep a slight bend to avoid excessive movement and injury to the joint caused by the resistance.
no4: female reproductive triangle
danger zone : the reproductive triangle is composed of deep transverse perineal muscle, urethral membrane sphincter and three layers of fascia below. This triangle region includes all female reproductive organs. The estrogen secreted by these organs allows women to maintain their unique menstruation, body shape, skin and body feeling.
dangerous formation: because women’s vagina is an open organ, bacteria will drive in if they are not careful. Due to the dark and humid environment of this part, it is especially suitable for the breeding of bacteria. When there is inflammation, the region is rich in blood vessels, which will make bacteria spread all the way up.
safety warning: as the area is close to the anus, there are many skin wrinkles and rich sweat glands, it is most important to do a good job of cleaning and protection. Especially during menstruation, you must change sanitary napkins frequently to avoid blood stains becoming a culture base for bacteria; Wash your hands before going to the toilet to avoid bacterial invasion.
no5: bladder triangle is easily injured by holding urine
danger zone : this area is composed of two ureteral orifices and urethral orifices. This is the place where the residual urine in the body is stored. The urinary system is one of the main ways for the body to detoxify. Therefore, the bottom of the bladder is the area where toxins and waste stay most.
dangerous formation: the mucosa at the bladder triangle is only a very thin layer of tissue, and the submucosal tissue lacks abundant blood vessels. Therefore, the blood supply is not sufficient and the self-protection ability is relatively poor. Most of the diseases in the bladder, such as cystitis, bladder tuberculosis and nephritis, occur here. In addition, although the urine is generally sterile, it is easy to breed bacteria. If you often hold the urine, it will weaken the contractile capacity of the bladder, and the urine cannot be completely emptied in the bladder, prompting the formation of bacteria and inflammation. The bladder is connected with the kidney, and the kidney is easy to be hurt.
safety warning: drink more water, at least 1000 ~ 2000 ml per day, and pay attention to regularly emptying the bladder to avoid bacterial proliferation; Keep the urethral orifice clean and dry; Eat more foods containing vitamin E. In addition, smoking is associated with a 3 fold increase in the risk of bladder cancer. Therefore, it is also important to quit smoking.
