Do you need 8 glasses of water everyday?
Your body is about 60 percent water.
With continuous activities every day, how much water do you really need to keep yourself from dehydration? Many studies have been conducted over the years and experts recommend 8 glasses of water every day, but in truth, your water intake depends on many factors, including daily activity, where you live, and your health status.
Although there is no single prescribed formula for your water intake, knowing yourself will help you to estimate how much water you need to drink each day.
You might need to modify your water intake based on several factors:
Exercise. If you do any activity that makes you sweat, you need to drink extra water to cover the fluid loss. It's important to drink water before, during, and after a workout.
Environment. Hot or humid weather can make you sweat and requires additional fluid. Dehydration also can occur at high altitudes.
Overall health. Your body loses fluids when you have a fever, vomiting or diarrhea. Drink more water or follow a doctor's recommendation to drink oral rehydration solutions. Other conditions that might require increased fluid intake include bladder infections and urinary tract stones.
Pregnancy and breast-feeding. If you are pregnant or breast-feeding, you may need additional fluids to stay hydrated.
Most healthy people can stay hydrated by drinking water and other fluids whenever they feel thirsty. For some people, fewer than eight glasses a day might be enough, but other people might need more. Your fluid intake is probably adequate if you rarely feel thirsty and the color of your urine is colorless or light yellow.
