Why do I have to drink water?

I have heard this so many times “Why do I have to drink water?”

Let´s deconstruct this and really get down to the nitty gritty of why we need to drink water.

Contrary to popular belief nutrients do not flow around your body in tea and coffee, they need blood. Blood is made up of aprox 90% water.

For your cells to communicate effectively and work efficiently they need water. For your hormones to disperse, your food to digest and your bones to be strong you need water. Every system in the body requires water.

Ok. You get the point. So your body is an incredibly amazing piece of kit and when it was designed, back in the day, it was fitted with a survival system called Fight or Flight to keep you safe when a sabre tooth tiger was about to attack.

Nowadays that sabre tooth tiger comes in the form of an angry boss, pile of bills or 6 weeks of kids being at home on school hols whilst you try to carry on with your work/life balance.

Stress = Dehydration. Dehydration = Stress.

Stress is very dehydrating on your body. When your body goes into Fight or Flight (F/F) physiological changes happen – adrenaline and cortisol is released and amongst many other things you lose water via sweating, urinating or defecating more (think IBS) – all lightening the load getting your body ready to run away. Water is cleverly diverted from your frontal cortex where you make your informed decisions to your hind brain where you make snap decisions. It is moved from wherever it may be (could be digesting your lunch or breaking down a tumour) into your arms and legs ready to run away or stay and fight.

Batten down the hatches!

Your body goes onto what we call Dehydration Alert and your cells start to build up a thicker cell membrane to keep in the water that they have inside and stop it from leaving. This means that cell communication and oxygen and nutrient flow is

impaired due to thick cell membrane. Stagnant water and toxicity builds up inside and the flow of fresh water into the cell is seriously impeded. Your cell starts to shrink. Your body does this to look after you though as some skanky water is better than no water at all.

F/F can also occur when we eat or drink certain foods. Anything that is a stimulant eg sugar, alcohol, caffeine sets the body off into F/F and it thinks it is under attack going through the  same physiological changes. Alcohol and caffeine are also diuretics meaning they overwork your kidneys and make you pee more. Some foods take a lot of water to digest such as wheat and dairy.

So the low down is steer clear of stimulants, stodge and stress!

Seriously though they will always be around so you just need to find away to limit the damage. Limit your intake of toxic stimulants such as coffee, booze, sugary and stodgy foods and up your intake of water rich foods, fresh juices and herbal teas. Find a way of dealing with stress so your cells can stay away from Dehydration Alert.

And yes. Drink more water!

I hope this has helped answer the age old question of why we need to drink more water and I would love to hear your thoughts – do you feel you drink enough water?

  1. I’ve never read such a brilliantly clear explanation of it. Thanks Sarra! I’ll get a glass of water once I’ve finished this wine. (Love the angry, dehydrated cells btw).

  2. Thanks Kate. Yes unfortunately even though wine is made from grapes and is watery it doesn´t count towards one of our “5 a day” or towards our 2 litres of water a day! Such a shame 😉

  3. Thanks for this Sarra! I was cycling to work a lot and not drinking enough water and found myself stressed out despite the exercise. You helped!!
