The Science Behind Grounding

Grounding, also known as earthing, is the practice of connecting the body to the Earth’s natural electrical charge. While it may sound simple, a growing body of research suggests this connection may play a role in supporting overall wellbeing, sleep, and recovery.

  • Some studies suggest grounding may help reduce inflammation markers in the body
  • Research has shown improvements in sleep quality in grounded participants
  • Grounding has been linked to reduced stress and cortisol levels
  • Early findings suggest improved circulation and blood flow

Studies

Study 1

A 2004 study published in the Journal of Alternative and Complementary Medicine found that grounding during sleep may help normalize cortisol levels, supporting better sleep patterns.

Study 2

A 2015 study by Oschman, Brown, and Chevalier observed improved blood viscosity after grounding, which may support circulation.

Study 3

Infrared imaging studies have shown reductions in inflammation markers in grounded subjects compared to control groups.

Who it may help

Grounding may support individuals who experience:

  • Poor sleep or insomnia
  • Stress and anxiety
  • Chronic fatigue
  • Muscle soreness or inflammation
  • Sedentary lifestyles (desk work, long sitting)

Important Note

While early research is promising, grounding is still an emerging area of study. It should not be considered a replacement for medical advice or treatment.
