The acronym SHIELD sums up the habits that may help ward off cognitive decline. SHIELD stands for sleeping at least seven hours per night, handling stress, interacting with friends, exercising daily, learning new things, and eating a healthy diet. Ideally, one should incorporate all of these healthy lifestyle habits into each day. If that feels overwhelming, doctors advise focusing on a different healthy habit per day, until it's possible to practice all of the habits every day.
