For a good health; Healthy Nervous system, Healthy Endocrine Glands and Healthy Digestive System is must. Spine and the brain is the key to health. Yoga is for developing Healthy Nervous system, Healthy Endocrine Glands and Healthy Digestive System. These three are very essential prerequisites for vitality and energy. You must follow the basic yoga guidelines.
Healthy Endocrine System
The most vital glands in the human body are the pituitary, pineal, thyroid, adrenal, pancreas and sex glands. The pituitary and pineal glands are situated in the brain, the thyroid is in the neck area, the adrenals and pancreas in the solar plexus area and the sex glands in the pelvic region. The function of these glands is to secrete powerful hormones which control your growth, weight and size. They also determine your metabolism, vitality, and emotional stability. Since the pituitary and pineal glands are situated in the brain, the headstand has a powerful effect on them.
Thyroid gland problems are very common and often go undiagnosed until the symptoms are very obvious. The shoulder stand is specific for the thyroid gland and will prevent and help cure thyroid gland problems.
The hormones secreted by the sex glands are key for sparkling eyes, smooth skin and a warm personality. The reverse posture stimulates these glands and therefore the production of the hormones.
The adrenal glands produce a variety of hormones such as adrenaline and cortisone that are important in controlling your stress and immunity. The twist posture is a powerful stimulant to the adrenal glands, causing them to release extra energy to boost your vitality level.
The correct functioning of the pancreas is vital to our health. The pancreas, secretes two hormones, called insulin and glucogen, which help to balance the body’s sugar level. If the pancreas is not working properly, diabetes may develop. Diabetes is a serious disease, since complications such as blindness, heart attacks or strokes may occur. To help prevent diabetes, it is recommended that you follow the nutritional principles outlined here, especially by avoiding concentrated sugar foods.
Healthy Nervous System (Brain and Spine)
Nerves from the brain and spine go to every tissue in the body and therefore the health of every tissue in the body depends upon the health of the brain and spine.
Yoga poses like headstand causes an increase in circulation to the brain, which stimulates the brain’s nerve cells. This results in increased vitality and improved brain function (intelligence and memory). Since the nerves from the spine go to all the organs and glands of the body, a healthy spine obviously plays an important role in vitality and rejuvenation. In fact, the spine is more critical to our well-being than the brain, since the brain is well protected by the cranium or skull bone. Where the spinal nerves leave the spine and pass through the intervertebral foramina is a very vulnerable area. If a vertebra is slightly out of place, it may cause the nerve to be ‘pinched’ in the intervertebral foramina. The spinal nerves do not have protection against mechanical insults as the brain does.
The ancient yogis fully understood the vulnerability of the spine and the tendency for slight spinal misalignments to occur. They also knew that if the spine was kept flexible by yoga asanas there would be much less chance of spinal misalignments. Some of the asanas will even correct some minor misalignments.
