Your brain is 80% water

So is yours :p

Is that before, during or after a small barrel of cider, G&T or beer?

Health benefits of water

Water is your body's principal chemical component, comprising, on average, 60 percent of your weight. Every system in your body depends on water. For example, water flushes toxins out of vital organs, carries nutrients to your cells and provides a moist environment for ear, nose and throat tissues.

Lack of water can lead to dehydration, a condition that occurs when you don't have enough water in your body to carry out normal functions.
How much water do you need?

Every day you lose water through your breath, perspiration, urine and bowel movements. For your body to function properly, you must replenish its water supply by consuming beverages and foods that contain water.
A couple of approaches attempt to approximate water needs for the average, healthy adult living in a temperate climate.

• Replacement approach. The average urine output for adults is 1.5 liters a day. You lose close to an additional liter of water a day through breathing, sweating and bowel movements. Food usually accounts for 20 percent of your total fluid intake, so if you consume 2 liters of water or other beverages a day (a little more than 8 cups) along with your normal diet, you will typically replace the lost fluids.
• Dietary recommendations. The Institute of Medicine advises that men consume roughly 3.0 liters (about 13 cups) of total beverages a day and women consume 2.2 liters (about 9 cups) of total beverages a day.

Even apart from the above approaches, it is generally the case that if you drink enough fluid so that you rarely feel thirsty and produce between one and two liters of colorless or slightly yellow urine a day, your fluid intake is probably adequate.



Staying safely hydrated

It's generally not a good idea to use thirst alone as a guide for when to drink. By the time one becomes thirsty, it is possible to already be slightly dehydrated. Further, be aware that as you get older your body is less able to sense dehydration and send your brain signals of thirst. Excessive thirst and increased urination can be signs of a more serious medical condition. Talk to your doctor if you experience either.
To ward off dehydration and make sure your body has the fluids it needs, make water your beverage of choice. Nearly every healthy adult can consider the following:

• Drink a glass of water with each meal and between each meal.
• Hydrate before, during and after exercise.
• Substitute sparkling water for alcoholic drinks at social gatherings.

If you drink water from a bottle, thoroughly clean or replace the bottle often. Refill only bottles that are designed for reuse.

Still or fizzy?:D

Tap(ped) or bottled?:frog:

brown or grey?:eek:

metered or unmetered:confused:

Ray

The hunger reflex is usually triggered when you're hydration levels drop, and usually a long time before the thirst reflex kicks in!
So if you already feel thirsty you have a lot of drinking time to make up! :D
and the next time you're feeling hungry, have a drink!
Mines a pink gin :p :burn:

Heh, maybe they need to be a little more precise with this point!

Well I never!

What happens if you don't drink enough liquids? Do you use less liquid to compensate (so that your overall fluid percentage remains the same) or you you end up shrivelling up as you eventually end up with no liquid in your body?

Wikipedia says:

Dehydration symptoms generally become noticeable after 2% of one's normal water volume has been lost. Initially, one experiences thirst and discomfort, possibly along with loss of appetite and dry skin. Athletes may suffer a loss of performance of up to 50%, and experience flushing, low endurance, rapid heart rates, elevated body temperatures, and rapid onset of fatigue.

...

The symptoms become increasingly severe with greater water loss. One's heart and respiration rates begin to increase to compensate for decreased plasma volume and blood pressure, while body temperature may rise because of decreased sweating. Around 5% to 6% water loss, one may become groggy or sleepy, experience headaches or nausea, and may feel tingling in one's limbs (paresthesia). With 10% to 15% fluid loss, muscles may become spas.tic [it's a medical term!], skin may shrivel and wrinkle, vision may dim, urination will be greatly reduced and may become painful, and delirium may begin.

Losses greater than 15% are usually fatal.
