Water helps get important nutrients to your kidneys and move waste to your bladder in the form of urine. If you don’t drink enough, the tiny filters inside your kidneys can get stopped up and lead to kidney stones and infections. Even mild dehydration can damage your kidneys if it happens often enough. Four to six cups a day is typically about right, but you might need more if you’re sick or out in the heat. Want to keep your kidneys healthy? Learn simple ways to protect your kidney health and support your overall well-being. wb.md/4jrmetY
