On the way to yoga, we should pay attention to the endocrine system, which is another important functional regulation system besides the nervous system
. 
The endocrine system can be divided into two categories: one is the endocrine organs, such as pituitary gland, pineal gland, thyroid gland, parathyroid gland, thymus gland, adrenal gland, etc., which exist independently in morphology and structure and can be seen by naked eyes; the other is the endocrine cells scattered in other organs and tissues, such as islets in pancreas, interstitial cells in testis and ovarian cells Cell and luteal cell
. 
Endocrine gland without excretory duct, also known as glandular duct
. 
Its secretions are hormones, which directly enter the blood or lymph, and are transported to the whole body through the circulatory system, mainly regulating the metabolism, growth and development or reproductive function of the body
. 
The influence of yoga postures on the endocrine system of the human body — the thyroid gland is located in the front of the neck
. 
It is an unpaired gland, brownish red and “H”, which is composed of the left and right lobes and the thyroid isthmus connecting the two lobes
. 
Thyroid gland secretes iodine containing thyroxine, which is mainly used to promote metabolism, accelerate blood glucose decomposition, maintain normal development and growth, especially for bone and nerve development
. 
Parathyroid gland is oblate oval, brown yellow, the size of mung bean, generally has two pairs, both attached to the posterior edge of the left and right thyroid leaves or buried in thyroid tissue
.
Parathyroid gland secretes parathyroid hormone
.
Its main function is to regulate calcium metabolism and maintain blood calcium balance
.
If parathyroid hormone secretion insufficiency, may cause the blood calcium to drop, appears the hand foot convulsion
.
In clinical practice, excessive secretion of thyroxine causes nervous system excitation and body metabolism
.
Most of them are excited, irritable, insomnia, nervous and anxious
.
Even palpitations, appetite, weight loss, sweating, eye protrusion and other symptoms
.
On the contrary, if the secretion is too little, there will be drowsiness, loss of appetite, obesity, ptosis and other symptoms
.
Yoga postures require us to keep deep and long breathing in a stable and comfortable position, while individual postures have a certain stretching effect on the front side of our neck
.
If combined with deep breathing, more oxygen is integrated into the blood, thus strengthening the blood circulation of the neck and enhancing the secretion of thyroxine
.
Therefore, it should be noted that patients with thyroid hormone secretion (hyperthyroidism) are not suitable for these postures
.
For example, we are familiar with the cobra, locust, bow and so on
.
Also because these postures belong to the hot postures, they are easy to accelerate the blood circulation in the body, making the body excited and in high mood
.
On the contrary, for patients with low thyroid hormone secretion, if the neck is not thick and oppresses the throat and trachea, these postures can be properly practiced
.
There is another point that needs to be explained
.
These postures have a strong effect on stretching the abdomen, stimulating and massaging the intestines and stomach
.
Therefore, people suffering from gastroptosis, intestinal tuberculosis, hernia and gastric ulcer are not suitable for practicing these postures, so as not to cause damage to the intestines and stomach mucosa, or aggravate the ptosis
.
In addition, our mandibular retraction postures, such as mandibular retraction, plow type, shoulder inverted position, lock the blood in the jaw, so as to stimulate the thyroid body and strengthen the metabolism in the body
.
Therefore, patients with hyperthyroidism are not suitable to practice mandibular retraction postures
.
However, for patients with hyperthyroidism, how to practice yoga? To recommend several: 1, practice some forward bending postures, such as leg back stretch, beam angle, head knee twist, etc., can reduce irritability, easy to make people calm
.
2
.
Practice rest technique, voice meditation, etc., can be very good to relax the mood, release the pressure, in the process of paying attention to oneself, stabilize the mood, improve the body’s excited state
.
3
.
Yoga breathing method can balance the metabolism of the body, slow down the heart rate, make the body quiet and peaceful, regulate the body function, stabilize the breathing and control the senses
.
How to practice yoga breathing? When doing any posture, don’t force yourself to bear the limit, breathe as deep and natural as possible, and learn to pay attention to self, so that consciousness and self, breathing and body can be integrated into a harmonious state given by yoga
.
The influence of yoga posture on the endocrine system of human body – adrenal gland is located at the upper end of the two kidneys, one on the left and one on the right
.
It is yellow, the left side is nearly half moon shaped, and the right side is triangular
.
The glandular parenchyma can be divided into outer cortex and inner medulla, and their structures and hormones are different
.
Adrenal cortex secretes a variety of hormones, such as the regulation of water and salt metabolism of mineralocorticoids (such as aldosterone)
.
In order to prevent blood loss, mineralocorticoids store sodium and increase blood content, which can lead to hypertension
.
In addition, it has the function of secreting sex hormones
.
The adrenal medulla secretes epinephrine and norepinephrine, both of which make the heart beat faster, strengthen the heart force, and contract the small arteries, thus raising the blood pressure
.
Human beings are in a state of stress for a long time
.
Smoking, drinking, irregular diet and unstable sleep will cause sympathetic nerve excitement and make adrenal medullary hormone secrete vigorously
.
Norepinephrine causes the contraction of peripheral arterioles, while epinephrine increases cardiac output and makes blood pressure rise
.
Sustained hypertension can promote the occurrence and development of atherosclerosis, and cause a variety of pathological changes of heart, brain and kidney
.
1
.
For the heart, high blood pressure and overload of left ventricle can make left and right ventricles hypertrophy and expansion; because of its impact on blood vessels, it can lead to myocardial ischemia
.
2
.
Cerebral arteriosclerosis can be accompanied by vasospasm or thrombosis, resulting in cerebral hemorrhage
.
3
.
Arteriosclerosis of renal arterioles, atrophy of some nephrons, compensatory hypertrophy of others, granular renal surface and thinning of cortex
.
4
.
In addition, there may be retinal hemorrhage, exudation and nerve papilledema
.
Adrenal gland belongs to the abdominal ring
.
These postures have good effects on the abdominal ring: 1
.
Twisting position – because twisting position mainly adopts abdominal breathing, it has good massage effect on the viscera around the navel, including kidney, intestine and stomach
.
Due to the torsion of the spine, the blood circulation around the spine is strengthened, so the secretion of adrenaline can be regulated
.
2
.
Forward bending posture: stretch back muscles and spine, which can nourish the lower spine
.
In addition, the forward bending posture can ease the mood, improve the irritable and nervous mood, so it can reduce the activity of peripheral sympathetic nerve, reduce the secretion of norepinephrine, and reduce the blood pressure
.
However, patients with hypertension must be careful to practice head down posture, or simply do not do, so as not to oppress the blood vessels in the head, causing danger! 3, butterfly, pigeon king style – relax the hip joint, at the same time improve the blood circulation of abdominal organs, relax the stomach, massage the back, promote renal blood circulation
.
When doing yoga postures, patients with hypertension must keep deep and natural breathing, do postures slowly, and cooperate with good ideas and breathing
.
Remember, do not hold your breath, especially the internal suspended breath, it is very appropriate to cause cardiac pressure, so that the peripheral blood pressure rise
.
In addition, drink light food, quit smoking and alcohol
.
For patients with hypotension, you can practice: 1, Japanese worship – promote blood circulation in the body, increase myocardial blood supply
.
2
.
Handstand posture – strengthen the blood supply to the head, restore brain energy, make brain cells full of vitality, and improve the mind
.
And it relaxes the blood vessels in both legs
.
Such as plow, shoulder handstand, etc
.
The influence of yoga postures on the endocrine system of human body pancreas is the second largest digestive gland of human body, which is located behind the stomach and horizontally adheres to the posterior abdominal wall at the height of the 1st and 2nd lumbar vertebrae
.
The shape of pancreas is long, which can be divided into three parts: head, body and tail
.
The head of pancreas is large, surrounded by duodenum
.
The body of pancreas is the middle part of pancreas, crossing the inferior vena cava and the front of aorta abdomen
.
The tail of pancreas is thin, extending to the upper left, to the lower back of splenic hilum.
