The human body can last weeks without food, but only days without water.
The body is made up of 50 to 75 per cent water. Water forms the basis of blood, digestive juices, urine and perspiration, and is contained in lean muscle, fat and bones.
As the body can’t store water, we need fresh supplies every day to make up for losses from the lungs, skin, urine and feces. The amount we need depends on our body size, metabolism, the weather, the food we eat and our activity levels.
Water is needed for most body functions, to:
– Maintain the health and integrity of every cell in the body
– Keep the bloodstream liquid enough to flow through blood
– Help eliminate the byproducts of the body’s metabolism, excess electrolytes
– Regulate body temperature through sweating
– Lubricate and cushion joints
– Reduce the risk of cystitis by keeping the bladder clear of bacteria
– Aid digestion and prevent constipation
When you experience thirst, you are usually already dehydrated
Symptoms of Dehydration:
Thirst, lethargy, dry nasal passages, headache, dry/cracked lips, confusion/hallucinations, tiredness, dark-coloured urine.
Aim for 3 liters per day, generally speaking and watch just about everything improve ☺
