Answer 1

My topic to be going to discussing is "WATER"

Human body can last weeks without food but without water we cant live many days.Human body is made up of 60-80% water. Body can't store water that can losses from the lungs,skin,urine,faeces.The amount of water depend upto the body size,metabolism,weather the food we eat and our daily activity level.

Role of water in body:

• Water maintain health weight of the body.Water helps to eliminate the waste product from the body and excess electrolytes(eg:Potassium,Sodium)
• Water helps to maintain and regulate the body temperature through sweating.
• Water moisten the mucous membrane such as lungs.
• It helps to lubricate joints and reduces the risk for developing cystitis by keeping the bladder free of bacteria.
• It helps to in digestion process and prevent constipation.
• Water can carry nutrients and oxygen throughout the body.
• Water serve as shock absorber inside the eyes and in the aminotic sac surrounding the foetus in pregnancy.
• Water helps to moisten skin to maintain texture.

Recommended fluid intake:

The recommended amount of fluid need every day depend on several factors such as age,gender,pregnant or breast feeding women.

Age	Quantity
Infant(Age 0-6 months)	0.7 L
Infant(7-12 months)	0.8 L
1-3yrs	1L
4-8Yrs	1.2L
9-13Yrs	1.6L
14-18Yrs	1.9L
19Yrs	2.6L
Pregnant women(14-18yrs)	1.8L
Pregnant women(19yrs)	2.3L
Lactating Women	2.6L

Food that contain enough water:

• Water is the best drink compare to other because it does not contain any energy.Water will boost and hydrate the body.
• Milk contain about 80 percent of water especially for infants.
• Different types of tea contain water like ginger tea,green tea, podina tea,lemon tea that helps to meet your daily requirement and contain the source of antioxidant and polyphenols ,which help to protect from the heart diseased and cancer.
• Fruits and vegetables also contain water such as oranges,apple, cucumber, tomatoes, Broccoli, grapefruit and watermelon.

No,I don't think that we are taking enough water in our daily busy schedule or any fasting conditions.

Consequences of too much of water is called as water intoxication:

• Drinking of too much can disrupt brain function by increasing the amount of water in blood that water can dilute all the electrolyte in the blood and eliminate through urine that may cause hyponatremia.
• If we observed decreased level of sodium in the body due to excess water consumption, the water may shift from inside to outside that make you swell.If these happen the place of brain,it might become dangerous and become fatal.Hyponatremia can cause nausea,vomiting,Increase blood pressure,swelling.
