Here’s a handy guide : How much water should i drink?
Some health gurus believe that you need to sip on water constantly throughout the day, even when you’re not thirsty. So, how much water should i drink is enough, good for health?
The body of a human adult is about 60% water. Water performs numerous critical physiological functions in the human body, including those of a solvent, a carrier for nutrients and waste products, a thermoregulatory and a lubricant. Staying properly hydrated is contributing to well-being.
Each individual’s needs are unique to them and depend on their health, age, size and weight as well as activity levels, the type of job they do and the climate they live in. Drinking little and often is the best way to stay hydrated.
Why drinking water ?
Juices or sugar-sweetened beverages can be drunk occasionally, but not all day long for daily hydration purposes. They are full of calories, which may impact health when over consumed. Since it contains no sugar or calories, plain water should be THE choice for daily hydration.
Mild dehydration may occur when only 1-2% of body weight is lost due to insufficient water intake. It may be accompanied by common symptoms such as headaches, dry or sticky mouth, thirst, sleepiness or tiredness. Research shows that mild dehydration can reduce cognitive (mental) as well as physical performance .
How much water should i drink?
We take in water both from food and drink but the amount of water we get from food alone is not enough to maintain the body’s water balance. In fact, the European Food Safety Authority (EFSA) estimates that we take in 80% our water from beverages (including water itself) and only 20% from food.
Current understanding of the body’s very precise water balance regulation mechanisms allows experts to estimate that, on average a healthy sedentary adult living in a temperate climate needs to drink 1.5L (8 x 200 mL glasses) over the course of a day.
This is an average amount because, of course, fluid requirements vary depending on factors such as age, gender, phase of life (for example, pregnancy), physical activity level, climate and diet
For those who feel more comfortable going off official guidelines rather than thirst, the UK’s NHS advises drinking between six to eight glasses of fluid a day, including lower fat milk and sugar-free drinks, including tea and coffee.________________________________________________________________________________________
