The word "Yoga" came from the Sanskrit word "yuj”, which means "to unite or integrate”, "to join". "Yoga" can be more accurately described by the Sanskrit word asana, which refers to the practice of physical postures or poses. Asana is only one of the eight "limbs" of yoga, the majority of others which are more concerned with mental and spiritual well-being than physical activity. In the West, however, the words asana and yoga are often used interchangeably. Ancient Yogis had a belief that in order for man to be in harmony with himself and his environment, he has to integrate the body, the mind, and the spirit. For these three to be integrated, emotion, action, and intelligence must be in balance.
Standing poses are often used as warm up or as a starting point for other poses. Standing poses are beneficial for strengthening your legs, opening your hips and develop stamina and your balance.
Seated poses are useful for practicing breathing exercises and relaxation or meditation techniques. Seated poses are also often used as a warm up or as a starting point for other poses. Performing seated poses can help improve your posture and flexibility of your hips, knees and ankles. You can perform twists to stretch and strengthen your back and abdominal muscles, increase the flexibility of your spine and improve your circulation.
These Asanas, if regularly practiced as per the instructions below, have great advantages incurring back pain and all spine related problems as it removes stiffness starting from the neck to the lower spine and greatly increases the flexibility. Further cures Asthma and Lungs related problems.
It is important to take time to perform relaxation or restorative poses at the end of each yoga practice. You can use this time to relax your body and mind and allow energy released by the poses in your practice to move freely throughout your body.
Balancing poses are great for improving your balance and coordination as well as developing your ability to remain grounded in a pose. Keeping your body balanced encourages you to focus, quiet and balance your mind.
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.
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.
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.
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 Shoulder stand, 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 haemoglobin 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.
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.
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.
Asana and pranayama probably improve immune function, but, so far, meditation has the strongest scientific support in this area. It appears to have a beneficial effect on the functioning of the immune system, boosting it when needed (for example, raising antibody levels in response to a vaccine) and lowering it when needed (for instance, mitigating an inappropriately aggressive immune function in an autoimmune disease like psoriasis).
Yoga quells the fluctuations of the mind, according to Patanjali’s Yoga Sutra. In other words, it slows down the mental loops of frustration, regret, anger, fear, and desire that can cause stress. And since stress is implicated in so many health problems—from migraines and insomnia to lupus, MS, eczema, high blood pressure, and heart attacks—if you learn to quiet your mind, you'll be likely to live longer and healthier.
