Grounding (Earthing): 10 Minutes Barefoot Outdoors

If you spend most of your day indoors, even ten minutes of barefoot outdoor time is a low-cost addition to your daily routine. Grounding (also called "earthing") asks you to stand or sit with bare feet on grass, sand, or unsealed earth for ten minutes a day. Advocates claim direct electron transfer from the ground reduces inflammation and improves sleep — the controlled evidence is sparse and based on small samples, so treat grounding as an outdoor habit rather than a validated protocol.

The protocol

• Surface: grass, sand, or unsealed earth (not concrete, not painted decking).
• Duration: 10 minutes.
• Frequency: daily if feasible — pair with morning light exposure for a single outdoor block.

What you get

• Guaranteed outdoor time, which independently correlates with better mood and circadian alignment.
• Possible parasympathetic (rest-and-digest) activation from the act of standing still outdoors.

Contraindications

• Open wounds on the feet.
• Sharp-object risk in the chosen environment (broken glass, debris).

Evidence level

Low. Published trials exist but are small (typically < 50 participants), short-duration, and frequently funded by grounding-product vendors. Treat it as a free, low-risk habit; do not buy expensive equipment.
