In a 1973 study by Oster, the effects of alpha brainwave entrainment on anxiety reduction were explored. Alpha brainwaves are associated with relaxation and calmness, and the study aimed to determine whether stimulating these brainwaves could help alleviate anxiety. Participants in the study were individuals diagnosed with anxiety. They underwent sessions of alpha brainwave entrainment and reported on their anxiety levels before and after the sessions.

The results showed a significant reduction in reported anxiety levels after the sessions, suggesting that alpha brainwave entrainment could be an effective method for managing anxiety. This study provides evidence that alpha brainwave entrainment could potentially be used as a non-invasive, non-pharmaceutical treatment for anxiety. In conclusion, Oster’s 1973 study provides promising evidence for the use of alpha brainwave entrainment in anxiety reduction, but further research is needed to fully understand the potential benefits and limitations of this approach.
