Many naturopathic doctors recommend dry brushing because it is said to stimulate the lymph nodes, aid the body in getting rid of toxins, improving digestion and kidney function, and more.
Athough, there have not been a great deal of scientific studies about dry brushing,most will agree that gently brushing the skin does have exfoliating benefits and may even help reduce stress too. The movement of the brush on skin helps loosen dead skin cells, remove dirt and oil and hence naturally exfoliating skin. Soon there is an improvement in skin texture and there is a healthy glow. When dry brushing you may feel an increase in circulation, or a relaxed/tingly feeling that sends signals to the brain that are similar to the relaxing effects of massage.
There are many articles and videos posted on line showing how to's. If you are interested in starting be sure to get a very soft and natural bristle brush. The natural bristle is softer and smoother reducing chances of causing abrasions. And starting soft will ease you into the process, with very soft and gentle strokes. Always stroke towards the heart, from feet to legs moving towards the trunk, then hands to arms and chest. Get as much of your back as you can reach, this is when a long handled brush comes in handy. I do my dry-brushing in the shower before I turn on the water, that way the dead skin...ew...can just go down the drain!
PS if none of these benefits appeal to you then there are some who say dry brushing can help with cellulite! Now that may just be worth the extra few minutes a day added to the shower routine
