Pay attention to the protection of the human danger triangle, because you can't understand these things without health.

Triangle is the most stable shape, but do you know? There are several dangerous triangles in the human body, so we can't touch them at will, otherwise it will have serious consequences. I believe everyone has heard of the facial danger triangle. This place can't be squeezed by hand at will, which is easy to cause facial infection. There are other triangles on the body that need our good protection.

1, physical danger triangle

First, the triangle of the face

Be careful to prevent infection.

The connecting line between the root of the alar and the corners of the mouth on both sides constitutes the "triangle" of our face. In this area, six veins leading to the skull pass through here, and they branch and communicate with each other, forming a dense vascular network.

High risk factors

Infection: There are abundant blood vessels around the mouth and lips, which communicate with intracranial capillaries. If you squeeze acne at will and shave carelessly, bacteria will invade from capillaries, which will easily lead to intracranial infection and serious illness.

Oral ulcer: be alert to recurrent attacks.

Acne constantly: beware of hair follicle infection.

Cracked corners of the mouth: Vitamin B2 and B3 may be lacking.

expert opinion/advice

If you have acne, don't squeeze it at will, pay attention to maintenance and do a good job of sun protection.

Ensure adequate sleep and avoid anxiety.

Clean frequently, the water temperature is 35℃ when washing your face, and choose mild and irritating cleansing products with weak acidity.

Adjust the diet to be light; Eat less sweet, oily and spicy food; Eat more egg milk and fish; Make sure to eat some dark green vegetables every day.

Second, the triangle of the neck

Exercise regularly to prevent strain.

The cervical vertebra consists of cervical vertebra, and the golden triangle of the neck refers to the area below the occipital bone of the neck, including the first cervical vertebra and the second cervical vertebra.

Normal cervical vertebra is slightly convex forward, and this curvature can increase the elasticity of cervical vertebra and slow down the head vibration. If you keep a bad posture for a long time, the lordosis of the neck will gradually become straight, or it will become kyphosis, which will oppress the nerves and blood vessels that work normally and easily lead to migraine and stroke.

High risk factors

Long-term bow, sedentary, cervical disc herniation.

Rough massage, cervical ligament injury.

Pillow or pillow is too high, cervical ligament strain.

Nest in the sofa, against the physiological curvature of the spine.

I slept too much on my desk, and my cervical vertebra was deformed.

expert opinion/advice

Correct sitting posture: shoulders back, spine upright, feet on the ground.

Move your neck: Turn your neck once every hour or two, with gentle movements.

Looking up and looking far: avoid sitting at your desk or bowing your head for a long time.

Sleep mode: choose a pillow suitable for sleep.

Cold and dampness: Cold and dampness can cause vasoconstriction and slow blood flow.

Third, the shoulder triangle

Correct posture and reduce pain

The shoulder triangle corresponds to the position of the upper arm shoulder deltoid muscle. The muscles in this area are very thick. The deltoid muscle surrounds the shoulder joint from front, outside and back, and the axillary nerve is distributed in it, which dominates the contraction and relaxation of the deltoid muscle.

However, the structure of the shoulder joint is relatively loose, and it is easy to damage the shoulder soft tissue due to instantaneous muscle strain; Shoulder joints are often used for various sports of the upper body. If overused, it will rub the surrounding soft tissue, which is prone to chronic strain or soft tissue inflammation.

High risk factors

People who study on the computer or sit for a long time suffer from scapular muscle strain.

Improper backpack posture such as one shoulder and oblique back can cause muscle soreness.

Sleeping in an incorrect position may not keep the natural curve of your back.

Wrong shoes. High heels and flip-flops can change the balance of the body, uneven stress on the spine and aggravate back pain.

expert opinion/advice

Avoid holding a posture for too long, and often stand up and wrap your shoulders.

It's best to carry your shoulders when backpacking, and don't carry heavy objects for a long time.

Fully warm up before exercise, exercise moderately, and keep the joints slightly bent during exercise to avoid hurting the joints due to resistance.

Fourthly, the triangle of bladder.

Pay attention to hygiene and avoid holding your urine.

The triangular area between the ureteral orifice and the internal urethral orifice on both sides is the high incidence area of bladder tuberculosis and tumor.

High risk factors

Less urination at ordinary times may induce stones. In addition, the female urethra is short, and intestinal bacteria are easy to breed in the vulva, and then invade the bladder through the urethra.

Male sedentary, high prostate pressure, affecting normal blood circulation, making glandular fluid excretion poor, causing prostatitis, not urinating in time, aggravating the condition.

expert opinion/advice

Empty bladder urine in time.

Drink plenty of water, guarantee 1500 ml every day, and flush the bladder.

Limit high purine diet, such as animal viscera and thick soup; Eat more foods rich in vitamin E, such as kiwi fruit, spinach and cabbage.

Pay attention to the hygiene of private parts, change underwear frequently and clean frequently.

V triangle of feet

Regular massage and diligent self-examination.

The plantar triangle refers to the forefoot area with the thumb as the vertex.

High risk factors

Not paying attention to hygiene: washing feet and changing socks is not timely, and fungal infection.

Often wear high heels: the foot is squeezed, leading to bunions, hammertoes and gliosis.

Serious illness: diabetes causes long-term unhealed foot injury; Hypothyroidism makes your hands and feet cold; Gout and arthritis produce big toes.

expert opinion/advice

Often soaking feet: it can speed up blood circulation, contact leg and foot pain and improve sleep. But the foot bath time should not be too long and the temperature should not be too high.

Keep exercising: lift your feet, stretch your knees and hook your feet, and swing your legs every day.

Hygiene: change socks in time and wear soft, comfortable and breathable shoes and socks.

2. Women's Danger Triangle

1No.: Face triangle prone to acne

Danger zone: this triangular area consists of the connecting line between the root and two corners of the alar. There are six veins leading to the skull in the head and face, which branch and communicate with each other to form a dense vascular network. This area is rich in blood vessels and nutrients, and wastes and toxins are removed in time, so facial skin is the most sensitive and active, and systemic problems can easily be reflected here.

Danger formation: facial vein is the only vein without venous valve, and venous blood keeps flowing to "waste treatment station" with waste. However, due to the special structure of the facial vein, blood will not only flow down to the jugular vein normally, but also flow up to the skull.

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 will easily enter the blood and wander around along the venous network, which is most likely to cause infections of organs such as eyes and nose, and even lead to intracranial infection, which is life-threatening.

Second: the occipital triangle causes headaches.

Danger zone: the occipital triangle refers to the area under the occipital bone, including the first cervical vertebra and the second cervical vertebra behind the neck. There are the most complicated joints in the human body: the pillow-the first cervical vertebra-the second cervical vertebra joint. The left-right rotation, nodding and shaking of the head are mainly accomplished by these joints. The normal cervical vertebra protrudes slightly forward, and the nerve artery passes through the middle. This radian can easily increase the elasticity of the cervical spine and slow down the head vibration.

Danger formation: If you keep a bad posture for a long time, the lordosis of the neck will gradually become straight or backward, which will oppress the nerves and blood vessels that work normally, 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 bends the head forward, which increases the pressure on the cervical spine and easily accelerates the pathological changes of the cervical spine; Keep your neck and shoulders warm, because cold is the easiest way to hurt your bones and muscles. If the neck is blown by cold air for a long time in an air-conditioned environment, it is prone to stiffness and pain; In addition, always correct the posture of head, neck, shoulders and back, and don't shrug your shoulders often; After maintaining the same posture 1 hour, we should pay attention to relaxing the shoulder and neck muscles, and do some flexion, extension and rotation of the head and upper limbs to enhance the ability of the neck and shoulder muscles to cope with sudden changes.

NO3: The easily injured shoulder triangle.

Danger zone: the shoulder triangle is equivalent to the deltoid muscle of the upper arm joint. The muscles in this area are very thick. The deltoid muscle surrounds the shoulder joint from front, outside and back, and the axillary nerve is distributed in it, which dominates the contraction and relaxation of the deltoid muscle. Other joints in the whole body can only do flexion and extension, while the shoulder joint can do five movements because of its special ball and socket structure.

Danger formation: due to the loose structure of shoulder joint, if you exercise improperly, it is easy to damage the soft tissue of shoulder 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, which is prone to chronic strain or soft tissue inflammation.

Safety warning: fully warm up before exercise so that muscles and ligaments can be fully stretched; The amount of exercise should be moderate, and all joints should be slightly bent during exercise to avoid excessive exercise and damage to joints due to resistance.

Fourth place: female reproductive triangle

Danger zone: Genital triangle consists of deep transverse perineum muscle, urethral sphincter and lower three layers of fascia. This triangle includes all the female reproductive organs, and the estrogen secreted by these organs maintains the unique menstruation, body shape, skin and body sensation of women.

Danger formation: Because women's private parts are open organs, if they are not careful, bacteria will March in. Because of this dark and humid environment, it is especially suitable for the growth of bacteria. When there is inflammation, the rich blood vessels in this area will allow bacteria to spread all the way up.

Safety tip: Because this area is close to anus, there are many skin wrinkles and rich sweat glands, it is most important to clean and protect it. Especially during menstruation, sanitary napkins must be changed frequently to prevent blood stains from becoming a culture base for bacteria; Wash your hands before going to the toilet to prevent bacteria from invading.

Besides facial triangle, there are privates triangle, shoulder triangle and so on. The triangle relationship of human beings is very fragile. In daily life, we need to protect our triangle, because the triangle is rich in blood vessels. Once injured by external force, it will cause symptoms such as massive bleeding, infection and shock, which will seriously endanger life safety.
