You need to drink a lot of water per day to stay healthy, but how much water should you drink per day? Well, first you need to determine your weight and then divide that number by two and then that number is how many fluid ounces you need to drink each day. Your body is also very close to being made of 70% water. There are also many ways to lose water including sweating, talking, breathing, etc. Bottled water is very unhealthy compared to tap water, which is way healthier than bottled water. We could dring too much water and could become fatal. Water can also heal heartburn, arthritis, back pain, and a lot more. My mom likes lemon water because it has vitamin C and keeps your body from getting sick and helps your liver get all the poison out of your body. I’m thankful for water.
