Whether Dr. David's underwear really works needs rational judgment. From the propaganda point of view, Dr. David's underwear is implanted with far-infrared light waves, which vibrate with the light waves of human life and continue to wear to open up the microcirculation of the human body, thus playing the role of anti-inflammatory, analgesic and promoting metabolism. Tens of thousands of people wear it, and they get up less at night, and their waist and legs can be less painful. Some people have improved dysmenorrhea and prostatitis for many years.

From a scientific point of view, whether Dr. David's underwear is really effective needs further verification. At present, many merchants apply far infrared technology to underwear and other products, but whether these products are really effective still needs to be verified by scientific experiments. At the same time, we should also be alert to the exaggerated propaganda and false propaganda of some businesses.

Therefore, if you are interested in Dr. David's underwear, I suggest you know more and compare more before buying, and spend rationally.
