Some ideas: Keep your weight in its recommended range for your height, gender, and age. Get plenty of rest and exercise. Lighten up—try to laugh more & stress less. Make sure your vitamin D level is within the normal range. Eat more foods containing omega-3 fatty acids. Don't smoke. Drink alcoholic beverages moderately. Get all recommended vaccinations.
