What is YOGA?

Yoga is basically a spiritual discipline which is based on an extremely subtle science that concentrates on bringing harmony between mind and body. It is a science and an art of healthy and sound living. The word ‘Yoga’ is derived from the Sanskrit word ‘Yuj’, signifying ‘to join’ or ‘to combine’ or ‘to unite’. Both Yoga and Ayurveda are historically closely related and have developed in tandem with each other since ancient times. According to Yogic sacred writings the act of Yoga prompts the union of individual consciousness with that of the Universal Consciousness, showing an ideal congruity between the mind and body, Man and Nature. Yoga is believed to balance the three doshas i.e Vata , Pitta & kapha. As indicated by modern scientists, everything in the universe is only an appearance of a similar quantum atmosphere. One who experiences this oneness of existence is said to be in yoga, and is named as a yogi, having achieved a state of freedom alluded to as Mukti, Nirvana or Moksha. Therefore, the prime objective of Yoga is Self-realization, to overcome all types of sufferings prompting ‘the state of salvation’ (Moksha) or ‘freedom’ (Kaivalya). Living with freedom in all aspects of life, health and harmony is the primary focus of yoga practice. “Yoga” likewise alludes to an inward science including an assortment of strategies through which people can understand this union and accomplish authority over their destiny.Yoga, being generally considered as an ‘Immortal cultural outcome’ of Indus Saraswati Valley civilization – going back to 2700 B.C., has substantiated itself taking into account both material and spiritual upliftment of humanity.Basic humane values are the very Identity of Yoga Sadhana.

20 ways yoga Improves health:

1. Builds muscle strength – Strong muscles do more than look good. They also protect us from conditions like arthritis and back pain, and help prevent falls in elderly people. And when you build strength through yoga, you balance it with flexibility. If you just went to the gym and lifted weights, you might build strength at the expense of flexibility.

2. Improves your flexibility – Improved flexibility is one of the first and most obvious benefits of yoga. During your first class, you probably won’t be able to touch your toes, never mind do a backbend. But if you stick with it, you’ll notice a gradual loosening, and eventually, seemingly impossible poses will become possible. You’ll also probably notice that aches and pains start to disappear. That’s no coincidence. Tight hips can strain the knee joint due to improper alignment of the thigh and shinbones. Tight hamstrings can lead to a flattening of the lumbar spine, which can cause back pain. And inflexibility in muscles and connective tissue, such as fascia and ligaments, can cause poor posture.

3. Perfects your posture – Your head is like a bowling ball—big, round, and heavy. When it’s balanced directly over an erect spine, it takes much less work for your neck and back muscles to support it. Move it several inches forward, however, and you start to strain those muscles. Hold up that forward-leaning bowling ball for eight or 12 hours a day and it’s no wonder you’re tired. And fatigue might not be your only problem. Poor posture can cause back, neck, and other muscle and joint problems. As you slump, your body may compensate by flattening the normal inward curves in your neck and lower back. This can cause pain and degenerative arthritis of the spine.

4. Prevents cartilage and joint breakdown – Each time you practice yoga, you take your joints through their full range of motion. This can help prevent degenerative arthritis or mitigate disability by “squeezing and soaking” areas of cartilage that normally aren’t used. Joint cartilage is like a sponge; it receives fresh nutrients only when its fluid is squeezed out and a new supply can be soaked up. Without proper sustenance, neglected areas of cartilage can eventually wear out, exposing the underlying bone like worn-out brake pads.

5. Protects your spine – Spinal disks—the shock absorbers between the vertebrae that can herniate and compress nerves—crave movement. That’s the only way they get their nutrients. If you’ve got a well-balanced asana practice with plenty of backbends, forward bends, and twists, you’ll help keep your disks supple. Long term flexibility is a known benefit of yoga, but one that remains especially relevant for spinal health.

6. Betters your bone health – It’s well documented that weight-bearing exercise strengthens bones and helps ward off osteoporosis. Many postures in yoga require that you lift your own weight. And some, like Downward- and Upward-Facing Dog, help strengthen the arm bones, which are particularly vulnerable to osteoporotic fractures. In an unpublished study conducted at California State University, Los Angeles, yoga practice increased bone density in the vertebrae. Yoga’s ability to lower levels of the stress hormone cortisol may help keep calcium in the bones.

7. Increases your blood flow – Yoga gets your blood flowing. More specifically, the relaxation exercises you learn in yoga can help your circulation, especially in your hands and feet. Yoga also gets more oxygen to your cells, which function better as a result. Twisting poses are thought to wring out venous blood from internal organs and allow oxygenated blood to flow in once the twist is released. Inverted poses, such as Headstand, Handstand, and Shoulderstand, encourage venous blood from the legs and pelvis to flow back to the heart, where it can be pumped to the lungs to be freshly oxygenated. This can help if you have swelling in your legs from heart or kidney problems. Yoga also boosts levels of hemoglobin and red blood cells, which carry oxygen to the tissues. And it thins the blood by making platelets less sticky and by cutting the level of clot-promoting proteins in the blood. This can lead to a decrease in heart attacks and strokes since blood clots are often the cause of these killers.

8. Drains your lymphs and boosts immunity – When you contract and stretch muscles, move organs around, and come in and out of yoga postures, you increase the drainage of lymph (a viscous fluid rich in immune cells). This helps the lymphatic system fight infection, destroy cancerous cells, and dispose of the toxic waste products of cellular functioning.

9. Ups your heart rate – When you regularly get your heart rate into the aerobic range, you lower your risk of heart attack and can relieve depression. While not all yoga is aerobic, if you do it vigorously or take flow or Ashtanga classes, it can boost your heart rate into the aerobic range. But even yoga exercises that don’t get your heart rate up that high can improve cardiovascular conditioning. Studies have found that yoga practice lowers the resting heart rate, increases endurance, and can improve your maximum uptake of oxygen during exercise—all reflections of improved aerobic conditioning. One study found that subjects who were taught only pranayama could do more exercise with less oxygen.

10. Drops your blood pressure – If you’ve got high blood pressure, you might benefit from yoga. Two studies of people with hypertension, published in the British medical journal The Lancet, compared the effects of Savasana (Corpse Pose) with simply lying on a couch. After three months, Savasana was associated with a 26-point drop in systolic blood pressure (the top number) and a 15-point drop in diastolic blood pressure (the bottom number—and the higher the initial blood pressure, the bigger the drop.

11. Regulates your adrenal glands – Yoga lowers cortisol levels. If that doesn’t sound like much, consider this. Normally, the adrenal glands secrete cortisol in response to an acute crisis, which temporarily boosts immune function. If your cortisol levels stay high even after the crisis, they can compromise the immune system. Temporary boosts of cortisol help with long-term memory, but chronically high levels undermine memory and may lead to permanent changes in the brain. Additionally, excessive cortisol has been linked with major depression, osteoporosis (it extracts calcium and other minerals from bones and interferes with the laying down of new bone), high blood pressure, and insulin resistance. In rats, high cortisol levels lead to what researchers call “food-seeking behavior” (the kind that drives you to eat when you’re upset, angry, or stressed). The body takes those extra calories and distributes them as fat in the abdomen, contributing to weight gain and the risk of diabetes and heart attack.

12. Makes you happier – Feeling sad? Sit in Lotus. Better yet, rise up into a backbend or soar royally into King Dancer Pose. While it’s not as simple as that, one study found that a consistent yoga practice improved depression and led to a significant increase in serotonin levels and a decrease in the levels of monoamine oxidase (an enzyme that breaks down neurotransmitters) and cortisol. At the University of Wisconsin, Richard Davidson, Ph.D., found that the left prefrontal cortex showed heightened activity in meditators, a finding that has been correlated with greater levels of happiness and better immune function. More dramatic left-sided activation was found in dedicated, long-term practitioners.

13. Founds a healthy lifestyle – Move more, eat less—that’s the adage of many a dieter. Yoga can help on both fronts. A regular practice gets you moving and burns calories and the spiritual and emotional dimensions of your practice may encourage you to address any eating and weight problems on a deeper level. Yoga may also inspire you to become a more conscious eater. One of the benefits of yoga is how the practices resonate through other areas of your life.

14. Lowers blood sugar – Yoga lowers blood sugar and LDL (“bad”) cholesterol and boosts HDL (“good”) cholesterol. In people with diabetes, yogahas been found to lower blood sugar in several ways: by lowering cortisol and adrenaline levels, encouraging weight loss, and improving sensitivity to the effects of insulin. Get your blood sugar levels down, and you decrease your risk of diabetic complications such as heart attack, kidney failure, and blindness.

15. Helps you focus – An important component of yoga is focusing on the present. Studies have found that regular yoga practice improves coordination, reaction time, memory, and even IQ scores. People who practice Transcendental Meditation demonstrate the ability to solve problems and acquire and recall information better—probably because they’re less distracted by their thoughts, which can play over and over like an endless tape loop.

16. Relaxes your system – Yoga encourages you to relax, slow your breath, and focus on the present, shifting the balance from the sympathetic nervous system (or the fight-or-flight response) to the parasympathetic nervous system. The latter is calming and restorative; it lowers breathing and heart rates, decreases blood pressure, and increases blood flow to the intestines and reproductive organs—comprising what Herbert Benson, M.D., calls the relaxation response.

17. Improves your balance – Regularly practicing yoga increases proprioception (the ability to feel what your body is doing and where it is in space) and improves balance. People with bad posture or dysfunctional movement patterns usually have poor proprioception, which has been linked to knee problems and back pain. Better balance could mean fewer falls. For the elderly, this translates into more independence and delayed admission to a nursing home or never entering one at all. For the rest of us, postures like Tree Pose can make us feel less wobbly on and off the mat.

18. Maintains your nervous system – Some advanced yogis can control their bodies in extraordinary ways, many of which are mediated by the nervous system. Scientists have monitored yogis who could induce unusual heart rhythms, generate specific brain-wave patterns, and, using a meditation technique, raise the temperature of their hands by 15 degrees Fahrenheit. If they can use yoga to do that, perhaps you could learn to improve blood flow to your pelvis if you’re trying to get pregnant or induce relaxation when you’re having trouble falling asleep.

19. Releases tension in your limbs – Do you ever notice yourself holding the telephone or a steering wheel with a death grip or scrunching your face when staring at a computer screen? These unconscious habits can lead to chronic tension, muscle fatigue, and soreness in the wrists, arms, shoulders, neck, and face, which can increase stress and worsen your mood. As you practice yoga, you begin to notice where you hold tension: It might be in your tongue, your eyes, or the muscles of your face and neck. If you simply tune in, you may be able to release some tension in the tongue and eyes. With bigger muscles like the quadriceps, trapezius, and buttocks, it may take years of practice to learn how to relax them.

20. Helps you sleep deeper – Stimulation is good, but too much of it taxes the nervous system. Yoga can provide relief from the hustle and bustle of modern life. Restorative asana, yoga nidra (a form of guided relaxation), Savasana, pranayama, and meditation encourage pratyahara, a turning inward of the senses, which provides downtime for the nervous system. Another by-product of a regular yoga practice, studies suggest, is better sleep—which means you’ll be less tired and stressed and less likely to have accidents. Sleep is one of the key benefits of yoga that nearly every practitioner can experience no matter what their skill level.
