Many health article give suggestion to drink eight glasses of water a day to keep your body trim and healthy. Unlike other vital nutrients, water doesn’t have specific daily requirements. Just like everyone has different caloric needs, a person’s water intake is affected by age, weight, activity level, and environment. If you are sick, live in a hot or high-altitude environment, have extended sweat sessions at the gym, or are pregnant or breast-feeding, you may have to adjust your fluid intake accordingly. You may not have to drink as much as you think.
Institute of Medicine gives estimation: Women should drink approximately 2.7 liters (about 11 cups) and men approximately 3.7 liters (more than 15 cups) of total water a day.
The key word in this sentence is total. Liquids can include water, juice, milk, plus all of the juicy fruits and veggies you eat each day. Fruits such as strawberries, cantaloupe, and grapefruit, and vegetables such as broccoli, cucumber, and spinach are more than 90% water. Eighty percent of our water intake comes from beverages, but the other 20% comes from food.
To get enough fluids for your body, drink plenty of water and other low-calorie, nutritious beverages, eat fresh fruits and veggies, and rehydrate soon when you are thirsty.(health)
