【科学研究告诉你,针灸到底什么原理】

【科学研究告诉你,针灸到底什么原理】古老的针灸是否真的有效,仍然存在争议,有些研究称针灸仅作为安慰剂。新发表的一项研究发现,针灸确实会导致我们的身体发生变化。如果采用正确的针灸方式,你的身体会在插入针头的地方释放更多的一氧化氮,增加血液流动,并引发您的身体释放天然麻醉剂,从而产生升温或变冷的感觉。探索针灸和细胞机制的关系之旅,刚刚开启~

What’s happening in your body during acupuncture?

Trials have shown mixed results, but a new study shows that something is happening when those needles go in

 

Thousands of years after acupuncture was invented, controversy remains over whether the Chinese traditional medicine technique works. While previous trials have shown mixed results, a new study shows that, at the very least, those needles really do cause something to happen in our bodies.

Scientists have long been skeptical about the value of acupuncture, though practitioners have questioned whether the acupuncture in many studies was done “correctly.” Other trials suggest that acupuncture does “work,” but only as a placebo. In a study published this week in the journal Evidence-based Complementary and Alternative Medicine, researchers measured the biological effect of the procedure. They found that if you do acupuncture correctly, your body releases more nitric oxide at the points where the needles are inserted. The nitric oxide increases blood flow and triggers your body to release natural anesthetics, which can create either warming or cooling sensations. (The study was funded in part by the National Institutes of Health.)

The scientists inserted acupuncture needles into 25 people, ages 18 to 60 and both men and women. Then they tried two different methods. In one, they twisted the needles for two minutes every five minutes, for a total of 20 minutes. In the other, they applied electrical heat for 20 minutes.

Using a device that can measure the molecules in specific skin regions, researchers were able to detect the nitric oxide being released at these acupuncture sites for both methods.

There are caveats, as always. The sample size is small, and these results should be considered in light of more skeptical research as well. Next, the team wants to do further research to understand the underlying cellular mechanisms and the differences between the two techniques.
