"Buddy up!" That's what swimming instructors say. Always swim with a partner, every time — whether you're swimming in a backyard pool or in a lake. Even experienced swimmers can become tired or get muscle cramps, which might make it difficult to get out of the water. When people swim together, they can help each other or go for help in case of an emergency.
Get skilled. Speaking of emergencies, it's good to be prepared. Learning some life-saving skills, such as CPR and rescue techniques, can help you save a life. A number of organizations offer free classes for both beginning and experienced swimmers and boaters. Check with your YMCA or YWCA, local hospital, or chapter of the Red Cross.
