Primary Function: Filled with about 1 lb. of hand-mined pink Tesla crystals encased in a military-grade Faraday bag and decorative outer cloth, the Deep Sleep Grounding Bag helps shield you from electromagnetic frequencies (EMFs), grounding and recharging your energy field for deeper, more uninterrupted sleep. Placed on or under the bed—especially at the head—you can experience up to ~60 % improvement in deep sleep, reduced stress, enhanced lucid dreaming, and an overall boost in wellness. Designed for anyone sensitive to EMFs or seeking better sleep quality via natural resonance and earth connection.
