Replace your ropes after any hard fall, or if it develops flat or soft spots, becomes stiff, or shows other signs of wear and tear. Don't use your climbing rope for anything other than climbing. In general, the longer and more vertical your course, the higher your risk for injuries.

To avoid dehydration, drink plenty of water before, during, and after your climbing sessions, especially if you are climbing outdoors in a hot or arid climate.
