If you want to get rid off from back pain that is the best option you can do.


I have seen several times who work the whole day would complain back pain. Though it is unavoidable but you can do some ways to relieve the condition. There are lots of activities that you can perform to relieve the back pain. However, the most preferred activity of many people is the yoga. The good thing about this activity is that it offers several benefits such as breathing techniques, exercises and postures. Once you perform yoga you can enjoy remarkable effects that can improve the pain and disorder.

Moreover, performing yoga exercise does not only relieve back pain but it can also relieve stress, increase resistance and improves health. Likewise, you body can benefit mental and physical strength when doing yoga exercise. Because your body is healthy you can resist diseases. In this sense, as soon as you feel back pain you should not think twice in adhering yoga exercise.

However, aside from tedious working, back pain can be the result of several health problems such as injuries in the ligaments and muscles, kidney problems and a lot more. Moreover, improper sitting position can also make you suffer back pain as well as tension and stress. That is why to completely relieve back pain and other health issues, performing yoga regularly is the best option.

The first thing to do in yoga exercise is to lay your back with the legs and arms relaxed. Inhale while bringing your knee close to the chest and hold for some time. Release your breath and return to the original position. Repeat the procedure with the other leg. The next position is called locust position. Lie flat allowing the forehead touching the surface. Stretch arms in such a way that your palms can touch the ground. Slowly lift your two legs without feeling pain.

The next position to perform is the corpse position. You can do it by lying on your back with the arms on the sides. You should perform it in a relaxing way and taking a slow breath. This position decreases the pain in the back as well as release the stress.This procedure is called back strengthening exercise that helps improve balance and control.

If you want to achieve effective result, you should perform the yoga exercises properly. You need to familiarize the different positions and techniques so that you perform the exercise with great ease. On the other hand, you should take into consideration your safety and comfort while doing yoga. Supervision from a certified yoga instructor is the best way to perform well.

Here I mentioned some images of yoga those we can follow when we need to perform accurately in different places with different positions.

Is physical exercise able to keep us fit??


We all know that physical activity is beneficial in countless ways, but even so, Dr. Mark Tarnopolsky, a professor of pediatrics at McMaster University in Hamilton, Ontario, was startled to discover that exercise kept a strain of mice from becoming gray prematurely.

In the experiment, Dr. Tarnopolsky and his colleagues used lab r

odents that carry a genetic mutation affecting how well their bodies repair malfunctioning mitochondria, which are tiny organelles within cells. Mitochondria combine oxygen and nutrients to create fuel for the cells — they are microscopic power generators.

All we know that the mitochondria have their own DNA, distinct from the cell’s own genetic material, and they multiply on their own. But in the process, mitochondria can accumulate small genetic mutations, which under normal circumstances are corrected by specialized repair systems within the cell. Over time, as we age, the number of m

utations begins to outstrip the system’s ability to make repairs. And after that mitochondria start to malfunction and to die .

Although many scientists consider the loss of healthy mitochondria to be an important underlying cause of aging in mammals. As resident mitochondria falter, the cells they fuel wither or die. Muscles shrink, brain volume drops, hair falls out or loses its pigmentation, and soon enough we are, in appearance and beneath the surface, old.

The mice that Dr. Tarnopolsky and his colleagues used lacked the primary mitochondrial repair mechanism, so they developed malfunctioning mitochondria early in their lives, as early as 3 months of age, the human equivalent of age 20. By the time they reached 8 months, or their early 60s in human terms, the animals were extremely frail and d

ecrepit, with spindly muscles, shrunken brains, enlarged hearts, shriveled gonads and patchy, graying fur. Listless, they barely moved around their cages. All were dead before reaching a year of age.

Except the mice that exercised.

Half of the mice were allowed to run on a wheel for 45 minutes three times a week, beginning at 3 months. These rodent runners were required to maintain a fairly brisk pace, Dr. Tarnopolsky said: “It was about like a person running a 50- or 55-minute 10K.” (A 10K race is 6.2 miles.) The mice continued this regimen for five months.

At 8 months, when their sedentary lab mates were bald, frail and dying, the running rats remained youthful. They had full pelts of dark fur, no salt-and-pepper shadings. They also had maintained almost all of their muscle mass and brain volume. Their gonads were normal, as were their hearts. They could balance on narrow rods, the showoffs.

But perhaps most remarkable, although they still harbored the mutation that should have affected mitochondrial repair, they had more mitochondria over all and far fewer with mutations than the sedentary mice had. At 1 year, none of the exercising mice had died of natural causes. (Some were sacrificed to compare their cellular health to that of the unexercised mice, all of whom were, by that age, dead.)

The researchers were surprised by the magnitude of the impa

ct that exercise had on the animals’ aging process, Dr. Tarnopolsky said. He and his colleagues had expected to find that exercise would affect mitochondrial health in muscles, including the heart, since past research had shown a connection. They had not expected that it would affect every tissue and bodily system studied.

Other studies, including a number from Dr. Tarnopolsky’s own lab, have also found that exercise affects the course of aging, but none has shown such a comprehensive effect. And precisely how exercise alters the aging process remains unknown. In this experiment, running resulted in an upsurge in the rodents’ production of a prote

in known as PGC-1alpha, which regulates genes involved in metabolism and energy creation, including mitochondrial function. Exercise also sparked the repair of malfunctioning mitochondria through a mechanism outside the known repair pathway; in these mutant mice, that pathway didn’t exist, but their mitochondria were nonetheless being repaired.

Dr. Tarnopolsky is currently overseeing a number of experiments that he expects will help to elucidate the specific physiological mechanisms. But for now, he said, the lesson of his experiment and dozens like it is unambiguous. “Exercise alters the course of aging,” he said.

Although in this experiment, the activity was aerobic and strenuous, Dr. Tarnopolsky is not convinced that either is absolutely necessary for benefits

. Studies of older humans have shown that weightlifting can improve mitochondrial health, he said, as can moderate endurance exercise. Although there is probably a threshold amount of exercise that is necessary to affect physiological aging, Dr. Tarnopolsky said, “anything is better than nothing.” If you haven’t been active in the past, he continued, start walking five minutes a day, then begin to increase your activity level.

The potential benefits have attractions even for the young. While Dr. Tarnopolsky, a lifelong athlete, noted with satisfaction that active, aged mice ke

pt their hair, his younger graduate students were far more interested in the animals’ robust gonads. Their testicles and ovaries hadn’t shrunk, unlike those of sedentary elderly mice.

Dr. Tarnopolsky’s students were impressed. “I think they all exercise now,” he said.
