The Original BON Acupressure Pillow
Bed of Nails works similar to acupuncture, as the pressure of the rounded nails against the skin can help the body release endorphins. Endorphins serve as the bodyʼs very own happiness drug, providing a sense of joy, energy, pain relief and oxytocin, which makes you calm and relaxed.
