How Much Water Should You Drink a Day

How Much Water Should You Drink a Day

The amount of water that your body requires every day depends on several factors such as body weight, health condition, daily physical activity and more. It is very difficult to answer the question, how much water should you drink a day because every body type is different. You need to fulfill the minimum requirement of water in your body, but you need to know how much that is at first.

The main sources of water for your body are vegetables, fruits, and fruit juices apart from the raw fluid itself. You should consume all these in good amount along with your regular food. This will contribute to the maximum water requirement in your body. Drinking water and other beverages contribute to most of the water in your body.

Out of the total water requirement, fruits and vegetables contribute about 25% of the water. So, even if you forget to drink water at regular intervals, the daily dose of vegetables and fruits can cover up to an extent. Although maintaining exact measurements of water consumption is extremely difficult, you should at least be aware of it.

For starters, you need to know that women require 91 ounces or 2.7 liters of water every day. On the other hand, men require 125 ounces or 3.7 liters of water. The approximate measurements are claims made by The National Academy of Sciences. As per scientific claims, you need to drink 80-100 oz of water every day.

When should you drink more water?

After the problem of how much water should you drink a day is over, you need to know when you need it more. Although life is impossible without water, there are certain times when you lose body fluid. This is when you should drink more water to replenish the shortage. The following are situations when you need that extra dose of water:

  • If you are suffering from a fever
  • If there is excessive sweating due to heat or physical activities
  • During the hot summer season
  • When you are not well due to diarrhea and you are vomiting

Some quick facts about water

  • As per reports, men consume more water compared to women
  • Lean tissues have more water than fatty tissues
  • The bodies of children and babies are made out of more water than adults. When a baby is born, it is made up of almost 78% of water. As it grows up to 1 year, the water content drops down by 10% to 13%.

Do you think you drink enough water?

A study was performed on 3,500 adults to prove how much water should you drink a day. As per the results:

  • 7% of adults do not consume drinking water at all
  • 36% of adults consume only 1-3 cups of water every day
  • 35% of adults consume only 4-7 cups of water every day
  • 22% of adults consume about 8 or more cups of water every day

People who consume at least a cup of fruits or vegetables every day are likely to drink a little less drinking water. We have already mentioned that drinking water is not the only source of water. Other beverages are also fluids that we can consume. However, drinking water is the healthiest as it contains no calories, alcohol or caffeine.

People who consume less or no drinking water are more likely to consume little or no fruits or vegetables. These people are risking their health due to fluid-deprivation. These people do consume some kind of fluid to stay alive. But such fluids that they consume are not healthy at all.

What are the risks of not drinking enough water?

Drinking water is extremely essential but drinking excessive or very little water is risky. Now we will get to know about these risks.

1. Dehydration

We already know the reasons why our bodies lose fluids. At times, the body also releases more fluids than it normally does. There is a high chance that you may suffer from dehydration in that case. The major signs of dehydration are extreme thirst and fatigue. Be careful if you notice that you are not urinating at regular intervals. It is riskier if the urine is darker in color than it should be.

Children may experience dryness in their tongue and mouth, no tears while crying and also dry diapers over a prolonged period. Other symptoms of dehydration include confusion, shock, mood swings, kidney stones, constipation and overheating. Treatment of mild dehydration is possible at home with increased water consumption. On the other hand, if there is a problem of major dehydration, you must go to the hospital.

2. Hyponatremia

Just like a lack of fluid causes dehydration, excess water causes Hypernatremia. This proves that drinking excessive water is also not at all good for our health. When we drink excessive water, a dilution process of the electrolytes in our blood happens. This is when the body’s sodium level drops and hyponatremia can occur. Symptoms and signs of the syndrome include confusion, coma, headache, seizures, fatigue, muscle cramps, spasms, weakness, irritability, and nausea.

Hyponatremia is a rare syndrome. Children who are unaware of their food requirements are at a higher risk of this problem. Also, sportspeople who tend to consume more water in a short time may suffer from hyponatremia. If you are at a risk due to excessive physical activity, you should try sports drinks containing extra sodium, electrolytes, and other minerals.
