In a 2018 study by Zhang, the effects of alpha brainwave stimulation on cortisol levels were explored. The study was based on the premise that alpha brainwave stimulation has been linked to a decrease in stress levels and an increase in relaxation. The research aimed to determine whether this form of brainwave stimulation could have a direct impact on cortisol levels, a hormone that is often elevated during periods of stress.

The study involved participants undergoing sessions of alpha brainwave stimulation while their cortisol levels were measured. The results showed a significant decrease in cortisol levels after the sessions, suggesting a direct link between alpha brainwave stimulation and decreased stress levels. This study provides evidence that such stimulation could potentially be used as a non-invasive, non-pharmaceutical treatment for stress and related conditions.

In conclusion, Zhang’s 2018 study provides promising evidence for the use of alpha brainwave stimulation in managing stress levels. By demonstrating a decrease in cortisol levels, the study suggests that this method could be a viable alternative to traditional stress management techniques. However, further research is needed to fully understand the potential benefits and limitations of this approach.
