The required nutritional composition of your glass of water will depend on its source. Mineral and spring water, which are typically derived from underground reservoirs and springs, may provide additional nutrients in the form of minerals like calcium and magnesium.Water is a colourless liquid composed of hydrogen and oxygen (H20). It is vital for life, and it supplies no calories.

Drinking adequate amounts of water, or staying hydrated, is the principal rule of health and nutrition. Our bodies can supposedly last weeks without food, yet just a few days without water. This makes sense when you realise our bodies are made up of about 60% water and that being dehydrated can affect us both physically and mentally. Humans are 60 percent water, our blood is 90 percent water and around 71 percent of the planet’s surface is covered by water.

There is no universally agreed quantity of water that must be consumed daily.Water is essential for the kidneys and other bodily functions.When dehydrated, the skin can become more vulnerable to skin disorders and wrinkling.Drinking water instead of soda can help with weight loss.Keeping hydrated is crucial for health and well-being, but many people do not consume enough fluids each day.

Here are some reasons our body needs water:

  • Drinking water improves memory and mood study has shown that even mild dehydration may impair memory and mood in everyone from children to the elderly. Hydration impacts the brain, as well as the body, and research has shown that even mild dehydration may have a negative impact on moods and may heighten anxiety. A lack of water may also increase the risk of a headache or migraines in some individuals. It cushions the brain, spinal cord, and other sensitive tissues Dehydration can affect brain structure and function. It is also involves in the production of hormones and neurotransmitters. Prolonged dehydration can lead to problems with thinking and reasoning.
  • Drinking water prevent constipation Water helps to ‘keep things moving’ in the digestive system, so staying hydrated may help prevent constipation in children, adults and the elderly. There is some evidence that carbonated water may be of particular benefit to aid weight maintenance The brain can’t actually tell the difference between hunger and thirst, so often we mistake thirst as a ‘sugar craving’. The next time you feel the need for something sweet, try a glass of water first.
  • Staying hydrated may also help with weight maintenance. Research has shown that having water before a meal may fill you up more and therefore promote weight loss through suppressing your appetite. A study in 2015 which diet drinks were swapped for water gave results which showed how water lead to greater reduction in weight and improved insulin resistance.
  • It prevents kidney damageThe kidneys regulate fluid in the body. Insufficient water can lead to kidney stones and other problems.In severe cases, dehydration can lead to kidney failure, which can be life-threatening. Possible complications of chronic kidney failure include anemia, damage to the central nervous system, heart failure, and a compromised immune system. When the kidneys are unable to maintain a balance in the levels of electrolytes, these electrical signals become mixed up. This can lead to seizures, involving involuntary muscle movements and loss of consciousness. Dehydration happens if we use and lose more water than the body takes in. It can lead to an imbalance in the body’s electrolytes. Electrolytes, such as potassium, phosphate, and sodium, help carry electrical signals between cells. The kidneys keep the levels of electrolytes in the body stable when they function properly. The leading cause of kidney stones is a lack of water. People who report them often do not drink the recommended daily amount of water. Kidney stones may also increase the risk of chronic kidney disease.
  • Drinking water also reduces the chance of a hangover When partying, unsweetened soda water with ice and lemon alternated with alcoholic drinks can help prevent overconsumption of alcohol.
