Having Eyes Closed

This is simply taking the time to close the eyes when safe to do so for any activity, such as sitting quietly, exercising in place, listening, etc..

Rationale: Most threats are perceived by the eyes. In modern life the eyes are used to scan the environment vigilantly. Using the eyes tend to shift to the sympathetic in these conditions. Also, when the vestibular system is weak, the eyes are misused to maintain balance as a primary system. It is true that ultimately, eye contact is the pinnicle of contact, but most people today have very tight eyes that need a shift.
