Drinking enough water is crucial for maintaining good health. It helps regulate body temperature, lubricate joints, transport nutrients and oxygen to cells, and remove waste from the body. Dehydration can lead to fatigue, headaches, dizziness, and other health problems. Aim to drink at least 8 cups (64 ounces) of water per day, more if you are physically active or live in a hot climate. Don’t like plain water? Try adding fresh fruit or herbs for flavor.
