38)Nature is timed to the alternating rhythm of light and dark produced by Earth’s rotation. (B) Birds sing, and blossoms open and close in tune with this twenty-four-hour cycle. Daylight also sets the pace for the activity of our mind. When deprived of regular intervals of dark and light, the mind can lose its bearings. (C) This is especially true with elderly people. For example, some older people whose brain function is fine at home can become confused when hospitalized where artificial light is always on.(A) The loss of rhythmic light and dark exposure will only worsen their condition. Simply moving the patient to a bed that is near a window and darkening the room at night can significantly improve mental state.
