Grounding has been shown to improve sleep quality and regulate circadian rhythms by affecting the secretion of cortisol, a stress hormone. Cortisol levels typically follow a diurnal rhythm, peaking in the morning and declining throughout the day. Disruptions in this rhythm can lead to poor sleep quality and various health issues. Grounding can help to normalize cortisol secretion, improving sleep patterns and reducing stress. Studies have shown that individuals who practice grounding experience improved sleep, reduced stress, and better overall well-being. References: Ghaly, M., & Teplitz, D. (2004).
