What is Huberman's view on grounding?

Huberman views physical grounding as something that may feel pleasant, but whose specific benefits are not strongly established; by contrast, psychological grounding—redirecting attention outward—can be a useful strategy during stress or panic.

• Physical grounding: It means direct contact with the Earth, such as placing bare feet on soil or grass. 1
• Evidence and mechanism: Some studies report benefits, but the evidence is not strong enough for firm conclusions. It remains unclear whether effects come from electron exchange with the Earth, the tactile sensation of contact, or other factors. 2 3
• His practical stance: He says to try it if it feels good, and suggests pairing bare feet on the ground with morning sunlight outdoors. He emphasizes that getting outside and sunlight have benefits independent of grounding. 4
• Psychological grounding: Shifting attention to external details—such as touching a table or noticing the shape of a doorknob—can change what feels most salient and may help during panic. 5
