If you mean by going to a forest or outside then yes it may lower stress and get vitamin d from sunlight.
But people say that grounding (touching the ground or earth) can give "free" or "mobile" electrons to your body that could reduce inflammation and reduces stress.
Its fake becausse our body biology is not based on absorbing free electrons from outside. the body use chemical reactions in which electrons are transferred from molecule to molecule inside your cells. And also you dont get constant flow of electrons when you touch the ground. Once you touch the ground the electrons quickly balances and there is no potential difference on the earth and the body. So no electron flow once after you touch the ground. and also most studies saying that grounding works has weak evidence and not conclusive
