Should you drink 8 glasses of water a day?
Well, it is indeed important to stay hydrated. However, there has been some discussion about this “recommended” daily intake of 8 glasses.
It is indeed the perfect way to ensure that your body is getting adequate hydration, but how do we know this?
Does your body actually signal to you that it is thirsty and needs water or can you just drink when you feel like it? Are we genetically programmed to need much less, as some researchers have suggested?
The common recommendation of 8 glasses of water a day traces back to 1942. At that time, the Food and Nutrition Board of the National Research Council released a paper suggesting that most people dramatically under-drink. In fact, the recommendation was 56-114 ounces of water a day (depending on your size and activity level).
The latest edition of the Dietary Guidelines, released in 2005, says that most adults will satisfy their fluid needs by letting thirst be their guide. They say “Concentrate on drinking water.”
But wait, if we don’t know how much we need, then how can we trust our thirst mechanism? Won’t we suffer from chronic dehydration?
Maybe our thirst mechanism is bad and we are in fact chronically dehydrated.
Let’s think about this.
First of all, if our thirst mechanism is that bad, how did we survive as a species?
Second, there are many places in the world where water is scarce, and still people manage to live in those places, so it can’t be that bad.
The recommendation to drink 8 glasses of water a day is based on research done on people who live in hot arid environments. These people sweat a lot and lose a lot of water. They also don’t eat much, hence they also lose lots of sodium (salt) through their urine.
Other factors that increase your need for water include:
* High fevers – fevers can cause you to have a increased sweating and an increased loss of vital minerals. * Menstruation: Most women notice an increase in the amount they urinate and the need to urinate more frequently when they have their periods. This is because blood is denser than other fluids so it weighs more than other fluids that pass through your body.
Just an ounce of blood weighs more than a pound of water. That’s why your doctor or midwife checks to see if you are hydrated by weighing your pee in grams. (If you’re curious, a normal-sized adult pees around 1.7 grams in 24 hours. If you weigh less than 1.2 gm, you are dehydrated.) That’s why you need to drink more water when you have your period. When eating a normal amount of food for you, most women find that they don’t need to drink any extra water during their periods as their pee still weighs enough. However, if you are dehydrated you will need to drink more water during your periods. One reason why people don’t feel like drinking when they are on their periods is not due to a lack of thirst, but rather a dislike of the taste of the water (due to its mineral content). One trick that some women in the past have used is to dilute their pee with extra water by drinking extra amounts of liquid. Another trick is to pee less often. This can be achieved by waiting until you really have to go, then going, even if you only peed a little bit. (Don’t worry, your kidneys will make up the difference later.) Peeing less often helps prevent them from peeing out all the extra minerals their bodies are holding onto. * Vomiting and diarrhea: Both vomiting and diarrhea can cause you to lose lots of water and vital minerals. If you’ve been vomiting or having diarrhea, you need to make up for the fluid loss. If you don’t make up for the fluid loss, you can become dehydrated and lose vital minerals as well. That’s why people who vomit or have diarrhea are often encouraged to drink clear sodas like 7-Up or ginger ale which contain lots of sodium and little potassium (electrolytes).
