OPIOID RECEPTORS SHOWN TO BE PART OF HYPERBARIC OXYGEN’S PAIN-RELIEVING EFFECTS

Recent research has shown that hyperbaric oxygen therapy (HBOT) can help alleviate pain both in acute and chronic cases. Much attention has focused on the anti-inflammatory effects of HBOT and associated reductions in pain.

This study, published in the European Journal of Pain in 2014, showed that opioid receptors may also have a big role in the positive effects of HBOT <view study>
